+We publish code-server on Homebrew [here](https://github.com/Homebrew/homebrew-core/blob/master/Formula/code-server.rb).

+# Replace VERSION with version
+brew bump-formula-pr --version="${VERSION}" code-server --no-browse --no-audit
+```

+#### npm
+
+We publish code-server as an npm package [here](https://www.npmjs.com/package/code-server/v/latest).
