Routing Requests

In this section, you will learn how to use vercel.json to route requests to your VCLight instance.

TIP

Detailed documentation about vercel.json can be found here

Routing all Requests to the Instance

This will make all traffic to go through the instance.

{
  "builds": [
    {
      "src": "src/*",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/(.*)",
      "dest": "src/main.ts"
    }
  ]
}

Among them, the builds item indicates how the project will be built.

It should be noted that, if builds item is missing, Vercel will use the build script in package.json to build.

The routes item indicates where the request should be routed.

If several routes conflict, Vercel will use the one that is higher in the list.

Routing Part of Requests to the Instance

If you just want the /api/* part to go through the instance, you should fill the routes item like this:

"routes": [
  {
    "src": "/api/(.*)",
    "dest": "src/main.ts"
  }
]

If you want static files to not pass through the instance, you can fill vercel.json like this:

{
  "builds": [
    {
      "src": "public/assets/*",
      "use": "@vercel/static"
    },
    {
      "src": "src/*",
      "use": "@vercel/node"
    }
  ],
  "routes": [
    {
      "src": "/assets/(?<file>[^/]*)",
      "dest": "public/assets/$file"
    },
    {
      "src": "/(.*)",
      "dest": "src/main.ts"
    }
  ]
}
