sentry-event-diff

The tool that let you diff JS SDK events between multiple browsers that run locally or on BrowserStack. Given 2 SDK urls (eg. one from CDN, one fresh bundle stored on S3), it'll show the differences between each corresponding usecase. Each usecase is a single way to throw an exception and it provides enough confidence to know, that your core changes didn't break a way in which SDK catches and translates them into the events.

Setup

1. Deploy to EC2
2. SSH into the instance
3. `node app.js
4. Move process to the background
5. BROWSERSTACK_USERNAME=<username> BROWSERSTACK_ACCESS_KEY=<key> node run.js or locally: HOST=<ec2-instance-url> BROWSERSTACK_USERNAME=<username> BROWSERSTACK_ACCESS_KEY=<key> node run.js

Locally

Run the app as explained above and go to http://localhost:3000/old first and then to http://localhost:3000/new. Observe the diff inside the terminal output.

Usecases

To add a new usecase copy/paste one of previous directories in usecases directory and change its behavior. The rest is automatic.
