Source Maps
Learn how to enable readable stack traces in your Sentry errors.
To enable readable stack traces in your Sentry errors, you need to upload your source maps to Sentry. Learn how to unminify your JavaScript code by watching this video or reading the step-by-step instructions below.
If you are using plain Cloudflare Workers, set upload_source_maps = true to your wrangler.toml file to enable source map generation.
The easiest way to configure uploading source maps is by using the Sentry Wizard:
npx @sentry/wizard@latest -i sourcemaps
The wizard will guide you through the following steps:
- Logging into Sentry and selecting a project
- Installing the necessary Sentry packages
- Configuring your build tool to generate and upload source maps
- Configuring your CI to upload source maps
This guide assumes you are using a Browser JavaScript SDK. For instructions on how to set up source maps for React Native, follow the source maps guide for React Native.
If you want to configure source maps upload manually, follow the guide for your bundler or build tool below.
- TypeScript (tsc)
If you're using one of webpack, Vite, Rollup or Esbuild, use the corresponding Sentry plugin instead (see section "Sentry Bundler Support").
- UglifyJS
- SystemJS
- GitHub Actions
If you're not using one of these tools, we assume you already know how to generate source maps with your toolchain and we recommend you upload them using Sentry CLI.
Though we strongly recommend uploading source maps as part of your build process, for browser applications it's also possible to host your source maps publicly.
