Improving web application performance

In this section, we will look at techniques that can be used to improve the performance of web applications. These techniques include, but are not limited, to:

• HTTP caching
• Compression
• Minification
• Bundling
• HTML optimization
• HTTP/2
• Content delivery networks (CDNs)
• Web font optimization

Leveraging HTTP caching

Many roundtrips between a client and a server may be necessary to load a page, and retrieving resources for that page from the server can take up significant amounts of time. The ability to cache resources that might be needed again so that they do not need to be transferred over the network on subsequent trips is an important part of improving web application performance.
