javascript - How to clear Nx cache

Question

I use Nx monorepo (https://nx.dev). It has a folder with Nx cache (./node_moules/.cache/nx/). Its size for now is over 3GB.

Is there a command for clear this cache from time to time?

Answer 1

I have implemented such a solution, but do not find it convenient. Perhaps NX has a command to clear its cache, but I did not find it.

package.json

  "scripts": {
    "nx": "nx",
    "postnx": "node checkAndClearCache.js",
  ...

checkAndClearCache.js

const fs = require('fs');
const rimraf = require('rimraf');
const getSize = require('get-folder-size');

const cachePath = 'node_modules/.cache/nx';
const maxCacheMb = 2048;

if (fs.existsSync(cachePath)) {
  getSize(cachePath, (err, size) => {
    if (err) {
      throw err;
    }

    const MBSize = (size / 1024 / 1024).toFixed(2);

    console.log(`*** NX cache size is ${MBSize} Megabytes`);
    if (MBSize > maxCacheMb) {
      console.log('*** CLEAR NX CACHE ***');
      rimraf.sync(cachePath);
    }
  });
}
