The ecosystem of NestJS
In software development, an ecosystem refers to the environment in which a technology or framework resides. This includes everything from community support to third-party libraries, tools, and services that complement the core offering. A rich ecosystem is often a sign of a mature and sustainable framework, and NestJS is no exception.
Third-party modules
The modularity of NestJS enables seamless integration with various third-party libraries. The following are some examples:
- TypeORM: For database interaction
- GraphQL: For building GraphQL APIs
- Passport: For authentication
- Swagger: For API documentation
Nest CLI
NestJS provides a powerful Command-Line Interface (CLI) tool that streamlines the development process.
Benefits
Leveraging the Nest CLI, here are the benefits you get:
- Code scaffolding: Easily generate modules, services, and controllers
- Build and serve: Compile and run your app with simple commands
Code snippet
Using the Nest CLI, here are some commands you can use to get started with a simple Nest project:
# bash code $ nest new my-new-project $ nest generate module users
The first command will help you set up a basic NestJS project with the name my-new-project. The second one will generate a new model under the created project. Before running it, you need to be in a NestJS directory.
These are only two commands provided by the Nest CLI. We will explore this further in Chapter 3 of the book.
Community support
A strong community ensures a framework’s sustainability. NestJS has an active community that contributes to the following:
- Documentation
- Tutorials
- Third-party modules
