SSR stands for Server-side rendering. It is a one of the popular techniques for rendering a normally client-side only single page app (SPA) on the server and then sending a fully rendered page to the client. Server side rendered pages will load faster because the content is available to the browser sooner.
Open next.config.js and add the generateBuildId function
// next.config.js
module.exports = {
generateBuildId: async () => {
// For example get the latest git commit hash here
return ‘my-build-id’;
}
};
Add the onDemandEntries config:
module.exports = {
onDemandEntries: {
// period (in ms) where the server will keep pages in the buffer
maxInactiveAge: 25 * 1000,
// number of pages that should be kept simultaneously without being disposed
pagesBufferLength: 2,
},
}
By default, localhost:3000
Next.js is React framework for SSR. There is Angular Universal for SSR with Angular.
You can use any CSS-in-JS solution in your and bundles styled-jsx supporting scoped css.
Create-react-app and next.js project is the routing system since Next.js creates different bundles for each base address. For each route, a separate file is created in the page folder. So, you need to use next/Link component instead of react-router-dom. Also, keep in mind that for static files the static folder is used, but not public, and bundles are located in the folder.next
