How can I clean (reset cache) of React Native using Expo. Not sure if it is cache issue : <p>I am building a simple React Native app with create-react-native-app using only react-navigation and base-64(base 64 encode/decode) as dependencies. Over time starting the app became slower and now sometimes it is getting stuck(waiting for about 30min) on "Starting packager..." after running NPM start.</p>

<p>I've tried starting it with "npm start -- --reset-cache" but nothing changed</p>

<p>Once it is up and running I don't get any error or warning in DevTools or terminal. Also there are no issues with the performance of the app</p>

<p>What can I do to make NPM start smooth and quickly as before? Are there any general steps I can take to troubleshoot this issue?</p>

<p>Here is my package.json</p>

<pre><code>{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
