# Sentry Release Management

## Overview

Manage the full Sentry release lifecycle: create versioned releases, associate commits for suspect commit detection, upload source maps for readable stack traces, and monitor release health with crash-free rates and adoption metrics. Every production deploy should create a Sentry release so errors are grouped by version and regressions are caught immediately.

## Prerequisites

- **Sentry CLI** installed: `npm install -g @sentry/cli` (v2.x) or use `npx @sentry/cli`
- **Auth token** with `project:releases` and `org:read` scopes from [sentry.io/settings/auth-tokens/](https://sentry.io/settings/auth-tokens/)
- **Environment variables** set: `SENTRY_AUTH_TOKEN`, `SENTRY_ORG`, `SENTRY_PROJECT`
- **Source maps** generated by your build (e.g., `tsc --sourceMap`, Vite `build.sourcemap: true`)
- **GitHub/GitLab integration** installed in Sentry for automatic commit association (Settings > Integrations)

## Instructions

### Step 1 — Create a Release and Associate Commits

Choose a release naming convention. Sentry accepts any string, but two patterns dominate production usage:

**Semver naming** ties releases to your package version:

```bash
# Semver: my-app@2.1.0
VERSION="my-app@$(node -p "require('./package.json').version")"
sentry-cli releases new "$VERSION"
```

**Commit SHA naming** ties releases to exact deployments:

```bash
# SHA: my-app@a1b2c3d (short) or full 40-char SHA
VERSION="my-app@$(git rev-parse --short HEAD)"
sentry-cli releases new "$VERSION"
```

After creating the release, associate commits. This is what powers **suspect commits** — Sentry's ability to identify which commit likely caused a new issue by matching error stack frames to recently changed files:

```bash
# Auto-detect commits since last release (requires GitHub/GitLab integration)
sentry-cli releases set-commits "$VERSION" --auto

# Or specify a commit range manually
sentry-cli releases set-commits "$VERSION" \
  --commit "my-org/my-repo@from_sha..to_sha"
```

When `--auto` runs, Sentry walks the git log from the previous release's last commit to the current HEAD. It stores each commit's author, changed files, and message. When a new error arrives, Sentry matches the stack trace file paths against recently changed files and suggests the author as the likely owner.

### Step 2 — Upload Source Maps and Release Artifacts

Source maps let Sentry translate minified stack traces into original source code. Upload them **before** deploying — Sentry does not retroactively apply source maps to existing events.

```bash
# Upload all .js and .map files from dist/
sentry-cli sourcemaps upload \
  --release="$VERSION" \
  --url-prefix="~/static/js" \
  --validate \
  ./dist
```

The `--url-prefix` must match how your JS files are served. The `~/` prefix is a wildcard that matches any scheme and host:

| Your script URL | Correct `--url-prefix` |
|-----------------|----------------------|
| `https://example.com/static/js/app.js` | `~/static/js` |
| `https://cdn.example.com/assets/bundle.js` | `~/assets` |
| `https://example.com/app.js` (root) | `~/` |

For multiple output directories (e.g., SSR apps):

```bash
sentry-cli sourcemaps upload \
  --release="$VERSION" \
  --url-prefix="~/" \
  ./dist/client ./dist/server
```

**Managing release artifacts** — list, inspect, and clean up uploaded files:

```bash
# List all artifacts for a release
sentry-cli releases files "$VERSION" list

# Delete all source maps for a release (free storage)
sentry-cli releases files "$VERSION" delete --all

# Upload a single file manually
sentry-cli releases files "$VERSION" upload ./dist/app.js.map
```

**Build tool plugins** (alternative to CLI uploads) — handle release creation, commit association, and source map upload automatically:

```typescript
// vite.config.ts
import { sentryVitePlugin } from '@sentry/vite-plugin';

export default {
  build: { sourcemap: true },
  plugins: [
    sentryVitePlugin({
      org: process.env.SENTRY_ORG,
      project: process.env.SENTRY_PROJECT,
      authToken: process.env.SENTRY_AUTH_TOKEN,
      release: { name: process.env.VERSION },
      sourcemaps: {
        assets: './dist/**',
        filesToDeleteAfterUpload: ['./dist/**/*.map'],
      },
    }),
  ],
};
```

### Step 3 — Finalize, Deploy, and Monitor Release Health

**Finalize** marks the release as complete. Until finalized, the release appears as "unreleased" in the UI:

```bash
sentry-cli releases finalize "$VERSION"
```

Finalizing affects three things: (1) issues resolved as "next release" are marked resolved, (2) the release becomes the baseline for future `--auto` commit detection, and (3) the activity timeline records the release.

**Record the deployment** to track which environments run which release:

```bash
sentry-cli releases deploys "$VERSION" new \
  --env production \
  --started $(date +%s) \
  --finished $(date +%s)

# For staging
sentry-cli releases deploys "$VERSION" new --env staging
```

**Match the SDK release** — the `release` string in your Sentry SDK init **must** match the CLI version exactly, or events will not associate with the release:

```typescript
import * as Sentry from '@sentry/node';

Sentry.init({
  dsn: process.env.SENTRY_DSN,
  release: process.env.SENTRY_RELEASE,    // Must match CLI $VERSION exactly
  environment: process.env.NODE_ENV,
});
```

**Release health dashboard** — after deployment, monitor these metrics at `sentry.io/releases/`:

- **Crash-free rate**: Percentage of sessions without a fatal error. Target > 99.5%.
- **Adoption**: Percentage of total sessions running this release. Tracks rollout progress.
- **Sessions**: Total session count. A session begins when a user starts the app and ends after inactivity or a crash.
- **Error count**: New errors first seen in this release versus regressions.

Enable session tracking in the SDK for release health data:

```typescript
Sentry.init({
  dsn: process.env.SENTRY_DSN,
  release: process.env.SENTRY_RELEASE,
  autoSessionTracking: true,   // Enabled by default in browser SDK
});
```

**Cleanup old releases** to manage storage and reduce noise:

```bash
# Delete a release and all its artifacts
sentry-cli releases delete "$VERSION"

# List all releases via API
curl -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" \
  "https://sentry.io/api/0/organizations/$SENTRY_ORG/releases/"
```

## Output

- Release created with a version identifier tied to semver or git SHA
- Commits associated for suspect commit detection and suggested assignees
- Source maps uploaded and validated for deobfuscated stack traces
- Release finalized with deployment environment and timestamps recorded
- SDK `release` value matching CLI version for event-to-release correlation
- Release health dashboard tracking crash-free rate, adoption, and session data

## Error Handling

| Error | Cause | Solution |
|-------|-------|----------|
| `error: API request failed: 401` | Auth token invalid, expired, or missing `project:releases` scope | Regenerate at [sentry.io/settings/auth-tokens/](https://sentry.io/settings/auth-tokens/) with `project:releases` + `org:read` |
| `No commits found` with `--auto` | GitHub/GitLab integration not installed in Sentry | Install at Settings > Integrations > GitHub, then grant repo access |
| Source maps not resolving | `--url-prefix` does not match actual script URLs | Open browser DevTools Network tab, copy the script URL, and set `--url-prefix` to match the path portion |
| Stack traces still minified | Source maps uploaded after errors were captured | Upload source maps **before** deploying — Sentry does not retroactively apply them to existing events |
| `release already exists` | Re-creating a release that was already finalized | Non-fatal: use `set-commits` and `sourcemaps upload` to update it, or use a new version string |
| `release not found` in SDK events | `Sentry.init({ release })` does not match CLI version | Print both values and compare — they must be identical strings (case-sensitive) |
| Crash-free rate not appearing | Session tracking disabled | Verify `autoSessionTracking: true` in SDK init (default in browser SDKs, must be enabled in Node.js) |

See [errors reference](references/errors.md) for additional troubleshooting.

## Examples

**Complete release script for CI/CD:**

```bash
#!/bin/bash
# scripts/sentry-release.sh — run after build, before deploy
set -euo pipefail

VERSION="${1:-my-app@$(node -p "require('./package.json').version")}"
ENVIRONMENT="${2:-production}"

echo "Creating Sentry release: $VERSION → $ENVIRONMENT"

sentry-cli releases new "$VERSION"
sentry-cli releases set-commits "$VERSION" --auto
sentry-cli sourcemaps upload \
  --release="$VERSION" \
  --url-prefix="~/static/js" \
  --validate \
  ./dist
sentry-cli releases finalize "$VERSION"
sentry-cli releases deploys "$VERSION" new --env "$ENVIRONMENT"

echo "Release $VERSION deployed to $ENVIRONMENT"
```

**Monorepo with multiple Sentry projects:**

```bash
# Each service gets its own release prefix
sentry-cli releases new "api@$SHA" --project api-backend
sentry-cli releases new "web@$SHA" --project web-frontend

# Upload source maps per project
SENTRY_PROJECT=api-backend sentry-cli sourcemaps upload --release="api@$SHA" ./api/dist
SENTRY_PROJECT=web-frontend sentry-cli sourcemaps upload --release="web@$SHA" ./web/dist
```

**Query release health via API:**

```bash
# Get release health stats
curl -H "Authorization: Bearer $SENTRY_AUTH_TOKEN" \
  "https://sentry.io/api/0/organizations/$SENTRY_ORG/releases/$VERSION/" \
  | jq '{version: .version, dateCreated: .dateCreated, commitCount: .commitCount, newGroups: .newGroups}'
```
