17. Next.js Tutorial (4). API Routes

 1. Create an API Route

Source: https://nextjs.org/learn/basics/api-routes/creating-api-routes

The files must be in the pages/api folder. In this example (pages/api/hello.ts), that can be accessed by http://localhost:3000/api/hello and will return {"text":"Hello"}

export default function handler(req, res) {
  res.status(200).json({ text: 'Hello' });
}

Note: Don't fetch an api route from getStaticprops or getStaticPaths

You can save to a DB some info from a form:

export default function handler(req, res) {
  const email = req.body.email;
  // Then save email to your database, etc...
}

So only one call is made, and it is made at build time . This is quicker. getServerSideProps()  that works on the server-side rendering and every call can produce different results as data changes. Use only if you need to render a page whose data must be fetched at request time such as authorization. //export async function getStaticProps() { / / only on pre-rendering export async function getServerSideProps ( ) { // only on server side rendering const allPostsData = getSortedPostsData ( ) ; return { props : { allPostsData , } , } ; } export default function Home ( { allPostsData } : { allPostsData : PostData [ ] } ) { return ( < Layout home > . . . . . . . Do not use API route inside getServ...
