Next.js client-only SPA example
Made this example to show how to use Next.js router for a 100% SPA (no JS server) app.
You use Next.js router like normally, but don't define
getStaticProps and such. Instead you do client-only fetching with
react-query, or similar methods.
You can generate HTML fallback for the page if there's something meaningful to show before you "know" the params. (Remember, HTML is static, so it can't respond to dynamic query. But it can be different per route.)
Don't like Next? Here's how to do the same in Gatsby.
