Allowed hosts for serverMiddleware

Question

I have built a NUXT app, and I've added to it a serverMiddleware for handling some REST endpoints and connecting to my database.

serverMiddleware: [
  { path: "/api", handler: "~/api/index.js" },
],

So my question is: How to restrict accessing to /api endpoints from only few hosts ? (like having a list of ALLOWED_ORIGINS)

Answer 1

Setting Access-Control-Allow-Origin in the header solved the issue as explained more in-depth on this answer: https://stackoverflow.com/a/32481816/8816585

Since at the end, this part of Nuxt is a regular Express app.
