only-allow-pro v1.0.2

cli usage

package.json

{
  "scripts": {
    "build": "only-allow node 16 && vite build",
    "preinstall": "only-allow npm 6.x"
  }
}

if current nodejs version is not match 16, vite build will not excuted!

supported names: ["node", "nodejs", "npm", "pnpm", "yarn", "cnpm"]

api usage

const { match } = require("only-allow-pro");

// current nodejs version is match 16 ?
if (!match("node", "16")) {
  console.log("must use nodejs 16 to start current project.");
  process.exit(1);
}

// current package manager is npm && curent package manager verions is 16
if (!match("npm", "6")) {
  console.log("must use npm and version 6.");
  process.exit(1);
}

we can put above judgement in some build config file, because build tool will load this file.

for example:

• vue-cli-service powered project => vue.config.js
• vite powered project => vite.config.js
• ...

why not use only-allow

only-allow is great node module, but it has some limitations.

• only-allow only support pm check, but not support version check.
• only-allow only support pm, not support nodejs version check.
