We’re working on a simple and powerful caching model for Next.js. In a previous post, we talked about This post will discuss the API design and benefits of 'use cache' It’s a JavaScript “directive”—a string literal you add in your code—which signals to the Next.js compiler to enter a different “boundary”. For example, going from the server to the client. This is a similar idea to React directives like Let’s start with a simple example: Behind the scenes, Next.js transforms this code into a se...
Lazar Nikolov is a Web Performance Developer Advocate at Your (smashing) email Weekly tips on front-end & UX We love client-side rendering for the way it relieves the server of taxing operations, but serving an empty HTML page often leads to taxing user experiences during the initial page load. We love server-side rendering because it allows us to serve static assets on speedy CDNs, but they’re unfit for large-scale projects with dynamic content. React Server Components (RSCs) combine the best ...
Web page load times and responsiveness to user action in web apps is a primary driver of user satisfaction–and both are often dominated by network latency. Latency itself is a function of the user's connection to the internet (Wifi, LTE, 5G), how far away the server is that the user is connecting to, and the quality of the network in between. While the latency numbers may seem low by themselves, they compound quickly. For example, a Metric Estimate Metric Impact Wifi latency to internet Wifi ad...

This section of the docs covers Each file convention can be defined using a static file (e.g. Once a file is defined, Next.js will automatically serve the file (with hashes in production for caching) and update the relevant head elements with the correct metadata, such as the asset's URL, file type, and image size....
