Detect if your code is running on Glitch

Detect-Is-On-Glitch

Creative name, right?

Well, in my defense, this is a very simple package. It simply tells you whether or not your code is executing inside of the Glitch environment.

Using

Options:

• Call via CLI
  • detect-is-on-glitch or isglitch
    • isglitch && echo "Running on Glitch"
  • You can use the -i or --invert flag to get !result, like so:
    • isglitch -i && echo "Not running on Glitch"
• Pull in to front-end

  <script src="node_modules/detect-is-on-glitch/dist/browser/glitch-detect.min.js"></script>
  <script>
  detectIsOnGlitch().then((res) => {
  	alert(`You are ${res ? '' : 'not '}on Glitch`);
  });
  </script>

• Backend / NodeJS

  const getIsOnGlitch = require('detect-is-on-glitch');
  
  getIsOnGlitch().then((isOnGlitch) => {
  	if (isOnGlitch) {
  		console.log('is on glitch!');
  	} else {
  		console.log('somewhere else!');
  	}
  });

Building

yarn build

Detection method

Right now, the detection method is extremely simple:

• Browser / client: Checks if the current URL belongs to Glitch, or a subdomain
• Server side: Checks for some env / process.env.* environmental variables that are injected by Glitch
  • For example, GLITCH_SHARED_INCLUDES_LEGACY_CLS
