How can getStaticPaths be used to define routes?

Imagine you have these 3 route paths stored in an array:

const routes = ["route1", "route2", "route3"];

To set up these paths, you would do the following:

export async function getStaticPaths() {

  const routes = ["route1", "route2", "route3"];

  const paths = routes.map((route) => ({ params: { id: route } }));

  return {
    paths,
    fallback: false, 
  };
}

I'm having trouble understanding what is happening within the map function. Can someone please explain it to me?

Answer №1

Using the map() function in Javascript is a common practice.

By employing this function, you can transform the array ["route1", "route2", "route3"] into an array of objects:

[{params: {'id': 'route1'}}, {params: {'id': 'route2'}}, params: {{'id': 'route3'}}]

This specific formatting method is outlined in the official NextJS documentation here
