Example Apps for the Sentry JS SDKs

This repository is a work in progress

The main purpose of this repository is to visualize the differences between the Sentry JS SDK version 7 and version 8. Those example applications can also be used as a reference for using the JS SDKs.

Setup

  1. Clone the repository
  2. Copy the .env.example file to .env and set the SENTRY_DSN variable in it

How to test apps and save the payloads

  1. Make sure you have a folder named like the app in payload-files.
    • Example: apps/express -> payload-files/express
  2. Run yarn start:[app], e.g. yarn start:express.
  3. Check the "Disable Cache" option in the DevTools Network tab of your browser.
  4. Open the following URLs in your browser.
  5. The json file will be generated.

Test URLs (for servers like express, fastify)

Test URLs (for meta frameworks like Next.js)
