Vue occupies an interesting position in the triumvirate of frontend JavaScript frameworks. Not hyped to the extent that React is, and not as established as Angular, it’s spent the last couple of years quietly minding its business and building an engaged and enthusiastic community of developers. One of these developers is Marina Mosti: her book Building Forms with Vue.js is just the latest step in her career journey from a backend developer getting frustrated with Java to Vue.js evangelist and educator. She’s a great person to explain the attraction of Vue.js, and to provide an insight into how she first entered the community - luckily, I was able to chat with her. Buy Building Forms with Vue.js on the Packt store. Her background is interesting: “I actually started out as a PHP developer and found myself in a position where I forced myself into learning front end. It’s not until very recently that I started doing front end in terms of it being my main focus” she says. Rather than moving deeper down into the stack, she has gone the other way, gravitating towards the front end. That might not be completely conventional, but it’s also indicative of the evolution of both JavaScript and frontend development in general. Read the first chapter of the book for free on the Packt platform. Rethinking JavaScript Things today, Marina suggests, are quite different. She’s quick to tell me, for example, that “the current state of JavaScript is just so much better than what it used to be,” and recalls a general antipathy towards JavaScript in the early years of her career that she “dragged… around for many years.” “I went to this very small school where they taught us the basics of front end development” she explains. “And for good or for bad the teachers were always very adamant about saying ‘oh don’t bother learning vanilla JavaScript because we have jQuery and vanilla JavaScript is so bad that you’re not gonna use it.’” However, the framework boom changed this. “I got to a point where all these cool frameworks were coming out and you just realise ‘hey I don’t know javascript; I know jquery so how do I make this jump?’” This ‘jump’ wasn’t without challenges. “Just having to go back and learn the basics - that has been the most ‘challenging’ part of going onto front end - because the front end that I knew [at the time] was php side-generated HTML code with maybe a little bit of javascript, maybe some CSS.” Read next: Vue maintainers proposed, listened, and revised the RFC for hooks in Vue API Laravel and Vue.js Marina explains that she first encountered Vue while using Laravel. “We... wanted to take advantage of this built-in connection that Vue had with Laravel. Obviously this didn’t involve any fancy set up, there was no vue CLI, nothing of this good pre-compiling or anything, it was just injecting vue into the html and creating the components there on the fly” However, discovering Vue in this way proved to be revelatory: it actually underlined what makes it, in Marina’s view, a great front end framework. “You don’t really have to commit to the whole framework,” she says; “it just got the job done for what I needed at that moment.” What problems can Vue.js solve? Marina has a pretty clear perspective on the challenges in front end development. “The problems we’re currently facing in front end development... is that people don’t want the old browsing experience where you’re clicking around and having to wait for reloads” she says. “We want to make applications… that are very performant, they have a great user experience, you are not waiting for page refreshes - it flows. What we are looking for is having your applications flow in a way that makes sense, like if you were using a desktop application.” Vue is particularly good for this, Marina explains, because of its “reusable component structure.” To a certain extent, this way of working is just another example of the wider trend across engineering towards breaking things apart. “You are trying to make these small units of code, that do this specific thing… a very common way to describe it is like this lego system where you’re just putting pieces on top of each other and it just starts making sense.” I’ve heard that analogy before in relation to containers - there’s clearly a recurring theme that’s evolving out of core principles of design. If Vue is well-suited to building lightweight but highly performant front ends, another important element is that it makes development relatively easy. Again, Marina contrasts working with Vue today with what JavaScript development looked like in the past. “You used to have... these massive massive amounts of code, and code separation of concerns was just very complicated to manage. You had to [do] a lot of overhead and work... trying to figure out how are we going to structure these files so that it makes sense.” The Vue CLI Tooling was also more complicated; something that the Vue CLI has helped to solve.“You had to deal with - at a very intricate level - how tools like Grunt worked, for example. And now you have like these pre-build tools like the Vue CLI which allow you to not have to really think about things," she says. “You don’t have to think like ‘hey, how is this going to get compiled? How is webpack going to figure things out?’ At least not at an entry level because you have it all neatly packed in this box for you with the Vue CLI.” Comparing Vue.js to React and Angular Although it’s clear that Marina is incredibly passionate and enthusiastic about Vue, she’s also circumspect about ranking JavaScript frameworks against each other. “All 3 frameworks are fantastic. All 3 get the job done. This is like asking someone why is this your favorite flavor of ice cream?!” Vue.js v. React She notes that React and Vue have a lot in common. “They share a lot of similarities - both of them use a virtual DOM… they both have this reactive component structure.” However, the key difference, from Marina’s perspective, is JSX. “If you’re talking about React, you’re talking about JSX, this approach where everything is javascript. You’re writing HTML inside the JavaScript, you’re writing CSS inside the JavaScript.” It’s JSX that puts Marina off React, saying that the way it requires you to work “doesn’t really click. I know how to do it, but just in the way I like to code things I prefer just having the separation where HTML is HTML, and where CSS is CSS.” Want to learn React.js?

Angular Angular, meanwhile, is “great for enterprise projects where you need this huge huge framework” says Marina. “But that also comes at a cost of having to know all the framework. All the libraries, everything that Angular brings to the table, you have to know TypeScript - it's just very opinionated at what it does and sometimes the shoe is going to be very big for the project.” So, for Marina, Vue has a degree of flexibility. It’s not as opinionated as Angular, and it doesn’t require you to write using JSX. “It can grow up until the point you need it to… From the smallest component in your application to powering full enterprise solutions.” And related to this, it means Vue is accessible - the learning curve isn’t that steep. “Vue is just very gentle in that you can start using it; you can start building things right away.” “There's a very good pay off in making yourself an expert in it... once you start getting into the core of Vue, and understanding all the little tools that are at your disposal… you can start building upon this knowledge... the framework can grow and adjust to what you’re needing.” Search the latest Angular eBooks and videos. The Vue.js community There are undoubtedly many technical reasons to consider using Vue. However, another aspect that Marina emphasises throughout our conversation is how welcoming and supportive the Vue community is. “The Vue community is one of the biggest selling points of why you should pick Vue and why Vue is so amazing.” The Vue community was, Marina says, integral in getting her to where she is now. “I was, at one point, not very into vue… and I just found a very welcoming community and a very inclusive community... People in the community care about other developers that are getting into Vue. We try our best to make this feel like a very safe, inclusive community to just get people in here and get them developing vue and help them out with the problems they’re having.” Marina deserves credit for playing a part in fostering a welcoming and supportive culture. Not only has she created a wealth of learning materials (such as a great free introductory tutorial series), she also works closely with Vue Vixens, and provides mentoring and support for other women finding their way in the industry. “This focus on education just basically became my goal… Hey, let’s do things to teach people, to get more people involved with vue,” she says. In an industry that’s sometimes defined by hyper-competitiveness, and marred by toxicity, it’s certainly a worthwhile and important goal. It’s something we can all work at.

This year's Skill Up survey produced some interesting results when it came to the best front end frameworks. Angular remains the most established tool with 40% of web developers reporting that they used it regularly. React is actually a little further behind, with 25% using it regularly. Similarly, Vue.js is growing but used by 20% of respondents. However, opinion was a little different when we asked what front end frameworks should win the battle of the 3 big front end tools. Respondents were split on Angular and React, with both JavaScript tools winning 34% of the vote. Vue wasn't far behind, at just over 30%. With the web development world apparently split over what framework is going to define the future of the field, how are we to pick them apart? Or do we even really need to worry? Read the report in full. Sign up to our weekly newsletter and download the PDF for free. The fact that we have three great front end tools jostling for developer attention is surely a good thing, right? To help us make sense of these trends, we caught up with Angular expert Minko Gechev to find out what he makes of web development in 2018, and what front end developers should be learning. Minko Gechev is the author of Switching Angular. You can find the latest edition here on the Packt Store. Which front end framework should you learn: Angular, React, or Vue? Respondents to the Skill Up survey were evenly split between Angular, React, and Vue in the 'battle of the frameworks'. Which do you think developers should learn, and why? In all of them, there are unique and interesting ideas which are worth exploring. I truly believe that learning all the major frameworks can help developers go to the next level! This doesn’t necessary mean to be proficient in all of them. Having a high-level understanding of how the frameworks work and how to use them is completely enough and will allow you to adapt according to the projects’ requirements. This is similar to learning programming languages from different paradigms – it helps you discover how problems are being solved in different ways. For the past a couple of years, the redux pattern became the de facto standard for state management in the modern front-end development. The good thing about redux is that it’s view agnostic so you can use it with any framework – Vue, React, Angular, etc. Angular has its own redux alternative called ngrx which empowers a declarative approach with RxJS but in general, it follows the same underlying pattern. My recommendation would be to understand how to manage the state of our applications because that’s probably the most complex problem that we’re solving in our day to day development process. Once we have a solid understanding of this, we can easily switch between different frameworks depending on the problems we’re solving, what the rest of the team is using, and the project’s requirements. A very interesting characteristic of learning Angular is that if we get comfortable with the framework we’d be also familiar with TypeScript, RxJS, and techniques such as dependency injection. This may look like an initial overhead but it’s a great long-term investment which pays off really well in large projects. How important is TypeScript to front end development? How important is TypeScript to modern web development? Why? Over the past a couple of years I see a strong increase in the excitement around the language, not only in the Angular world but also in React and Vue. I’m personally using TypeScript for a few projects – a platform that we built with React and an educational application written in Angular. I see a lot of value in using TypeScript. Recently I haven’t started any project with JavaScript – for everything new I’m using TypeScript and I’m trying to migrate, as many of my existing projects as possible.There are a few reasons for this: TypeScript provides great development experience! Especially, combined with VSCode, you can instantly notice when you’ve misspelled a property, method, you’re trying to access a property of a nullable value, etc. It gives you a sense of security that your program is correct to given extent. Of course, TypeScript cannot save us from logical mistakes but if we use its type system wisely, we can get great benefits. You might be curious what benefits? Well, TypeScript can help us reduce the number of bugs in our programs. In the study “To Type or Not to Type: Quantifying Detectable Bugs in JavaScript” the authors shown that the average JavaScript program can benefit with 15% bug reduction if it uses the type system of TypeScript. The study was using TypeScript version 2.0; with the latest features of the language the number of detectable bugs is growing dramatically. Since recently webpack is leveraging TypeScript as well because it helps discover already existing issues in the codebase. Web developers and JavaScript fatigue Do you think we're past web developers experiencing 'JavaScript fatigue'? JavaScript is very dynamic and it moves very quickly. There are a lot of potential issues which could be caused by a variety of reasons. With semantic versioning and powerful type systems (such as the type system of TypeScript), we’re walking in the right direction but we definitely have a long way to go until the ecosystem matures. Web development over the next 12 months: WebAssembly and machine learning What do you think will be the most important thing for developers to learn in the next 12 months? There are a lot of exciting things happening nowadays! Web browsers are getting more and more powerful, exposing hundreds of APIs and opportunities. WebAssembly is moving very quickly and I believe that together with Rust it has a lot of potential in future. On the other hand, Google recently announced TensorFlow.js. This is a library which allows us to use machine learning (ML) in the browser. In the next years, ML is going to take a larger portion of our development process (directly or indirectly) for: Implementing features in our applications Improving development process I’m specifically interested in the second point – improving our development process by using ML. Together with Addy Osmani, Kyle Mathews, and Katie Hempenius, we’ve been working on a toolkit called Guess.js. It aims to provide predictive bundling and pre-fetching based on ML techniques in order to let us develop faster Angular/React/Vue/etc. applications. I’m really excited about what’s coming up in near future! So are we! Thanks for taking the time to speak to us, Minko!

Angular is one of the most popular JavaScript frameworks. Today, it's jostling for position with React and Vue as the leading front-end development framework. But if you're not using it, you're probably wondering why you should switch to Angular at all. What makes Angular such a good web development framework? And what does it give you that the likes of Vue and React don't? To help you decide if you should switch to Angular, we spoke to Minko Gechev, author of the third edition of Switching to Angular. Minko has worked incredibly closely with the Angular project - he was the author of the Angular 2 style guide. That means he's well placed to explain the benefits of Angular and to help you decide if its the right framework for you. Key Takeaways: Angular as against the public opinion has a consistent development lifecycle and is trustworthy for the developers to start their career with. The primary goal of the Angular community is to make the framework lighter and much more efficient. The book Switching to Angular - Third Edition works as a perfect stepping stone for new developers looking to start their journey with Angular. Angular.js and Angular are two different frameworks. Often people incorrectly refer to AngularJS as Angular version 1 which makes developers think that Angular is the next version of AngularJS. Although similar in nature, they should never be considered as predecessor and successor.   How has Angular come to dominate front-end development? What do you think is the primary reason for Angular to have the lion's share of front-end development market? Minko Gechev: There are several important reasons: Angular is a really well-designed framework which provides entire solution for the developers working on the user interface. The framework is developed and maintained by Google. This means that it is very well engineered and a high-quality solution. Angular provides great development experience. Since the beginning Angular was designed to simplify the development process dramatically. The framework provides friendly APIs which makes the process of building complex user interface trivial. Out of the box, Angular has very performant and well tested implementations of two-way data-binding, dependency injection and change detection. Notice that these will not only reduce the boilerplates in the process of application development but also make our code more testable, thanks to dependency injection. This means that the Angular team also thinks about improving the quality characteristics of our applications. On top of that Angular for web development provides a lot of external modules maintained by the Angular team itself, so the same team which works on Angular core, also develops Angular router, Angular forms, Angular material, etc. This allows us to confidently use the entire stack without bothering that the individual pieces of the puzzle may not fit well together. Another important fact is that the framework is developed by Google. This implies a high-quality engineering power for enterprises and individuals who can confidently bet on Angular as a long-term solution for development framework. As it is unlikely from Google to drop support for the framework unexpectedly. Keeping in mind that Angular is used in tonnes of projects inside Google itself, we can rest assured that it’s being tested on a very high-scale constantly. Google would never make a compromise in terms of quality. Development experience is something I am really interested in. The framework is developed with TypeScript. It provides great tooling support implemented in different text editors and IDEs; with precise auto completion suggestions and warning about typing errors; developers’ productivity can increase a lot. On top of that, Angular’s templates are very convenient for static analysis. This helps programmers to build tools which ease the development process even further. A few examples of such tools are codelyzer and the Angular Language Service. Finally, the framework provides predictable release schedule following semantic versioning. We always know what changes to expect in the next release to plan accordingly. What would you like to tell your followers about the latest development in the Angular eco-system? MG: Google is constantly making Angular for web development smaller and faster. Each new release introduces better tooling which drops more unused code from the bundles and makes them smaller. The Angular compiler also brings plenty of optimizations which transform our applications to better  performant versions of themselves. At the same time, we can see very minor incompatibility changes across major releases. The Angular team does an amazing job in making sure that they improve the framework a lot behind the surface but for us, the developers, they leave the APIs unchanged. On the other hand, we have the Angular community which builds on top of the core. There are plenty of community tools improving our day-to-day development process. Also, there are plenty of high quality material which help us to get started with the framework. Should beginners use Angular? Would it be advisable for a newbie JavaScript developer to start using Angular or would you suggest any other framework? MG: I’d definitely encourage beginner JavaScript developers to give Angular a try. They will build good habits by using TypeScript and have less bugs in their code because of the language’s type system. Also, Angular CLI is a great starting point for bootstrapping a new project - no matter whether you’re a beginner or an expert. What makes this book a must have for the would be Angular developers? MG: The book provides a gentle introduction to all the framework’s concepts. In the first chapters, we focus on ideas rather than digging into unfamiliar code. By the time we start writing applications, readers already have a good understanding of the framework foundation so they can just start coding without any struggle. As a former member of the Angular mobile team and long-term contributor, I have revealed implementation details which will help readers get in-depth knowledge about how everything works under the hood. From my teaching experience, I’ve noticed different patterns which help people develop a deeper understanding of new concepts and use them in practice. The main challenges of making the switch to Angular What are the main challenges that anyone would face while shifting to Angular framework? MG: There might be some conceptual overhead in the beginning. The framework encourages us to use best practices which means there might be a lot of new concepts, such as dependency injection, two-way data-binding, observables and Ahead-of-Time compilation. It takes time and practice to digest everything but the good thing is that we can do that incrementally. In the book I provide a step-by-step approach - we start developing fully functional applications with the bare minimum and after that increase our expressiveness and architecture by introducing new ideas and concepts. [box type="info" align="" class="" width=""]Check out this post to learn how to build components using Angular.[/box] Is Angular's dominance fragile? Angular is going through a lot of changes presently, do you feel that these many changes can impact the developer retainability of a particular tool or tech, especially when there are frameworks like React and Vue breathing down the neck of Angular? MG: The incorrect perception about fragility in the Angular’s API is a result of the rewrite of AngularJS. Often people incorrectly refer to AngularJS as Angular version 1 which makes developers think that Angular is the next version of AngularJS. This is incorrect. Angular and AngularJS are completely different frameworks, the only thing in common is that Angular is inspired by AngularJS. This incorrect statement also makes people think that the changes which will happen between Angular version 5 and Angular version 6, for instance, will be as impactful as the changes which happened between Angular version 2 and AngularJS. This is wrong as well. In fact, there were almost no backwards incompatible changes between Angular version 2 and Angular version 5 which means that the API is under strict control and the migration process between major releases is always only related to update of the project’s dependencies’ versions. Regarding the other libraries and frameworks out there such as React and Vue, I see that they are introducing a lot of new ideas as well. There’s competition which is very healthy since it allows the entire ecosystem to constantly evolve. 3 key features of Angular Please share three of the most remarkable features that you feel makes Angular special. Why should people switch to Angular? The dependency injection mechanism of the framework which makes our code testable and enforces better separation of concerns. I’ve had to use other alternative technologies in the past and I can honestly say that this is the feature I missed a lot. The Angular compiler is another remarkable feature. It transforms our application to much more performant versions of itself. Finally, I like the Angular templates. They have plenty of good features and thanks to the great design the Angular compiler is ableto perform a variety of optimizations over our applications. Could another framework replace Angular? Do you in the near future see any framework replacing Angular in popularity and if yes then why? MG: The JavaScript landscape has been very dynamic for the past couple of years. Although Vue is built by independent developers, recently there’s a noticeable focus on frameworks developed and maintained by large companies, such as React and Angular. I think this trend will stay because it’s much safer to bet the future of your product on a framework supported by a big organization. This means it is less likely to have unexpectedly discontinued maintenance and support. With all the qualities that Angular has, I believe that the framework has a very bright future. It has been adopted by a lot of large companies - Microsoft, Capital One, NBA, VMware, Google and many others. [box type="info" align="" class="" width=""]Check out this post on 5 web development tools that will matter in 2018[/box] When Angular made the breaking change to version 2, everyone was divided in their opinion about whether it was the right step, what was your thought? MG: As I mentioned above, Google didn’t introduce breaking changes to version 2 - they created a brand new framework inspired by AngularJS. It’s incorrect to refer to Angular as Angular 2, Angular 4, or Angular 5, etc. It’s just Angular. There’s a new major release of the framework every 6 months. At the moment we’re at version 5; 5 months from now Angular will reach version 6, etc. The differences between Angular version 2 and Angular version 5 are insignificant, there were very minimal backwards incompatible changes. It’s pointless to refer to every new version of Angular by placing a number behind unless we’re describing any specific change which happened across releases. In “Switching to Angular” I’ve focused on the solid foundation of the framework which is unlikely to change in near future. At ng-conf 2017 I introduced a tool which can automatically migrate any Angular application between versions 2 and 4 which simplified the transition process even further. On the other hand, AngularJS (which is incorrectly called Angular 1) is still in use, although Google strongly encourages developers to migrate to Angular. How is this book a stepping stone for a new Angular web developer and what should they try their hands on next? MG: “Switching to Angular” provides a great starting point for any intermediate JavaScript developer who wants to learn Angular. In case the reader has prior experience in AngularJS the transition of their mindset from AngularJS to Angular will be extremely smooth because of the comparison between the two frameworks that is provided. The book also explains in detail what should be the expectations of the readers regarding the future of the framework. If you are interested to get started with Angular javascript framework Switching to Angular - Third Edition is the go-to book to align with.  

Jason De Oliveira works as a CTO for MEGA International, a software company in Paris (France), providing modeling tools for business transformation, enterprise architecture, and enterprise governance, risk, and compliance management. He is an experienced manager and senior solutions architect, with high skills in software architecture and enterprise architecture. He has been awarded him MVP C#/.NET by Microsoft for over 6 years for his numerous contributions to the Microsoft community. In this interview, Jason talks about the newly introduced features of .NET Core 2.0 and how they empower effective cross-platform application development. He also gives us a sneak-peek of his recently released book Learning ASP.NET Core 2.0 Packt: Let's start with a very basic question. What is .NET Core? How is it different from the .NET Framework? Jason De Oliveira: In the last 20 years, Microsoft has focused mainly on Windows and built many technologies around it. You can see that easily when looking at the ASP.NET and the .NET Framework in general. They provide a very good integration and extend the operating system for building great desktop and web applications, but only on the Windows platform. In the last 5 years, we have seen some major changes in the overall strategy and vision of Microsoft due to major changes in the IT market. The cloud-first as well as the mobile-first strategy coupled with the support for other operating systems has lead Microsoft to completely rethink most of the existing frameworks - including the .NET Framework. That is one of the major reasons why the .NET Core framework came into existence. It incorporates a new way of building applications, fully embracing multi-platform development and the latest standards and technologies - and what a great framework it has turned out to be! ASP .Net Core 2.0 was recently announced in August 2017. What are the new features and updates introduced in this release to make the development of web apps easier? The latest version of ASP.NET Core is 2.0, which, provides much better performance than the other versions before it. It has been open-sourced, so developers can understand how it works internally and adapt it easily to specific needs if necessary. Furthermore, the integration between .NET Core and Visual Studio has been improved. Some other important features of this new release are: The Meta-Package which includes everything necessary to develop great web applications has been added to the framework An improved NuGet compatibility has been added. This leads to much better developer productivity and efficiency. Web development can be fun and using .NET Core in conjunction with the latest version of Visual Studio proves it! What benefits does Entity Framework Core 2 offer while building a robust MVC web app? When you are building web applications, you need to store your data somewhere. Today, most of the time the data is stored in relational databases (Microsoft SQL Server, Oracle and so on). While there are multiple ways of connecting to a database using ASP.NET Core, we advise using Entity Framework Core 2, because of its simplicity and because it contains all necessary features already built-in. Another big advantage is that it abstracts the database structure from the object-oriented structure within your code (also commonly called ORM). It furthermore supports nearly all databases you can find on the market either directly or via additional providers. When it comes to .NET Core, do you think there is any scope for improvement? What can Microsoft do in the future to improve the suite? To be honest ASP.NET Core 2.0 has achieved a very high level of feature coverage. Nearly everything you can think of is included by default, which is quite remarkable. Nevertheless, Microsoft has already shipped an updated version called ASP.NET Core 2.1 and we can expect that it will further support and evolve the framework. However, an area of improvement could be Artificial Intelligence (AI). As you might know, Microsoft is currently investing very strongly in this area and we think that we might see some features getting included with the next versions of ASP.NET Core. Also in terms of testability of code and especially live unit testing, we hope to see some improvements in the future. Unit tests are important for building high quality application with less bugs, so having a thorough integration of ASP.NET Core with the Visual Studio Testing tools would be a big advantage for any developer. Tell us something about your book. What makes it unique? With this book, you will learn and have fun at the same time. The book is very easy to read, while containing basic and advanced concepts of ASP.NET Core 2.0 web development. It is not only about the development, though. You will also see how to apply agile methodologies and use tools such as Visual Studio and Visual Studio Code. The examples in the book are real world examples, which have been added to build a real application at the end. Not just stripped down sample examples, but instead examples that you can adapt to your own application needs quickly. From the start to the end of the book we have applied a Minimum Viable Product (MVP) approach, meaning that at the end of each chapter you will have evolved the overall sample application a little bit more. This is motivating and interesting and will keep you hooked. You will see how to work in different environments such as on-premises and in the cloud. We explain how to deploy, manage and supervise your ASP.NET Core 2.0 web application in Microsoft Azure, Amazon and Docker, for example. For someone new to web development, what learning path in terms of technologies would you recommend? What is the choice of tools he/she should make to build the best possible web applications? Where does .NET Core 2.0 fit into the picture? There are different types of web developers, who could take potentially different paths. Some will start with the graphical user interface and be more interested in the graphical representation of a web application. They should start with HTML5 and CSS3 and maybe use JavaScript to handle the communication with the server. Then, there are API developers, who are not very interested in graphical representation but more in building efficient API and web services, which allow reducing bandwidth and providing good performance. In our book, we show the readers how to build views and controllers, while using the latest frontend technologies to provide a modern look and feel. We then explain how to use the built-in features of ASP.NET Core 2.0 for building Web APIs and how to connect them via Entity Framework 2 with the database or provide a whole host of other services (such as sending emails, for example).
