Source maps

Readable stacks via CLI or dashboard

Symbolication needs the same release string in the SDK and on the uploaded map.

SDK

typescript

TraceRN.init({
  apiKey: "trn_live_xxx",
  release: "1.2.0", // must match upload
});

CLI (recommended for CI)

bash

npm install -g @tracern/cli
# or: npx @tracern/cli ...

export TRACERN_API_URL=https://tracern-api.devlys.com
export TRACERN_TOKEN=trn_live_xxxxxxxx   # project API key
export TRACERN_PROJECT_ID=proj_xxx

tracern sourcemaps upload \
  --release 1.2.0 \
  --file ./android/app/build/generated/sourcemaps/react/release/index.android.bundle.map

EAS / GitHub Actions sketch

yaml

- run: npx @tracern/cli sourcemaps upload --release ${{ env.APP_VERSION }} --file ./dist/index.map
  env:
    TRACERN_TOKEN: ${{ secrets.TRACERN_API_KEY }}
    TRACERN_PROJECT_ID: ${{ secrets.TRACERN_PROJECT_ID }}

You can also upload from Project → Settings → Source maps in the dashboard.
