Another composition API plugin for Vercel's Micro

@infinitex/micro-use

Another simple Micro plugin, to make it run with composition API.

Example

import micro from "micro";
import { hooked, useBody } from "@infinitex/micro-use";

const handler = () => {
  const { name } = useBody();
  return "hello " + name;
};

micro(hooked(handler)).listen(3000);

There is no middleware, you can create your own hook to do the stuff such as permission verification.

import micro from "micro";
import {
  hooked,
  sendReject,
  useContext,
  useHeader,
} from "@infinitex/micro-use";

const useAuth = async () => {
  const { res } = useContext();
  const headers = useHeaders();
  const user = await verify(headers.token);
  if (!user) {
    sendError(res, 403, "unauthorized");
  }
  return user;
};

const handler = async () => {
  const user = await useAuth();
  // do anything with user
  return { msg: "..." };
};

micro(hooked(handler)).listen(3000);

Install

yarn add https://github.com/InfiniteXyy/micro-use

Note

I use global variables to keep the request parameters. To avoid conflicts, the useContext function should be placed at the beginning of the synchronization function.

const handler = async () => {
  const project = await useProject();
  DB.findAll();
  const user = await useAuth(); // Wrong! may lead to strange problems
};

const handler = async () => {
  const project = await useProject();
  const user = await useAuth(); // Correct! useContext should beyond all async functions
  DB.findAll();
};

Principle

The library is very lightweight and offers only a few functional approaches, so it can work well with other micro libraries.
