Clear Nx Cache

Nx cache can be cleared by removing files in the directory node_modules/.cache/nx.

Sometimes, you have to clear cache. For example, if you moved a component to another library, the component was still kept in the cache of the old library. This may break builds.

We have implemented this solution in our project:

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);
    }
  });
}

You can also use the --skip-nx-cache flag :)

This was top result on google for me, so wanted to add this here, that nx now has a way of clearing the various caches etc: nx.dev/reference/core-api/nx/docum...
