Releasing a New Version

To release a new version:

• Merge all changes to main.
• Update the version field in package.json.
• Commit and push your changes.
• Create a release in GitHub.
  • GitHub actions will automatically publish to NPM.
  • The bundled latest.js files are published to the Edgio CDN.

Build outputs

We have 2 build outputs of the package:

1. Using typescript (tsc) which is published to ./dist and then to NPM
2. Using webpack (webpack) which is published to ./cdn and then to Edgio CDN

In the app tests we can test both outputs of the RUM (CDN and NPM package). You can control this by running inside the integration-tests/app-test folder:

• npm run use:latest for using the latest.js file (You need to put in public folder)
