What are @vercel/routing-utils's main functionalities?

Define Routes

This feature allows you to define custom routes for your application. The 'src' field specifies the incoming request path, and the 'dest' field specifies the destination path.

{
  "routes": [
    { "src": "/about", "dest": "/about.html" },
    { "src": "/blog/(.*)", "dest": "/blog/post?slug=$1" }
  ]
}

Rewrites

Rewrites allow you to map an incoming request path to a different destination path without changing the URL in the browser.

{
  "rewrites": [
    { "source": "/old-path", "destination": "/new-path" }
  ]
}

Redirects

Redirects enable you to redirect an incoming request to a different URL with a specified status code, such as 301 for permanent redirects.

{
  "redirects": [
    { "source": "/old-blog", "destination": "/new-blog", "statusCode": 301 }
  ]
}

Headers

This feature allows you to set custom headers for specific routes. The 'source' field specifies the route, and the 'headers' field contains an array of headers to be set.

{
  "headers": [
    { "source": "/api/(.*)", "headers": [ { "key": "Cache-Control", "value": "no-cache" } ] }
  ]
}
