EAS CLI Skill

Procedural knowledge for operating the Expo Application Services CLI (npx eas) covering OTA updates, builds, submissions, channels, and branches. All commands run via npx eas in a Bash shell.

Output Mode Strategy

Apply this output strategy to every command:

Always include --non-interactive to prevent stdin prompts that block execution. Exception: The eas credentials command requires interactive mode for credential selection flows.

Permission Model

• Read/query commands — Execute freely without asking: list, view, status
• Mutation commands — Always confirm with user before executing: update (publish), delete, rollback, republish, channel:edit, channel:pause, build (trigger), submit, branch:delete

OTA Updates

The most critical command group. Manages over-the-air JavaScript bundle updates.

List updates on a branch

npx eas update:list --branch <branch> --limit <n> --non-interactive [--json]

Key flags: --branch (required unless --all), --all, --platform android|ios|all, --runtime-version <ver>, --limit (default: 25, max: 50), --offset (pagination).

View update group details

npx eas update:view <GROUP_ID> [--json]

Takes a group ID (the group field in update:list --json output).

Publish an update (MUTATION)

npx eas update --branch <branch> --message "<msg>" --platform <platform> --non-interactive

Key flags: --branch or --channel (target), --message (required description), --platform android|ios|all, --rollout-percentage <1-100> (gradual rollout), --auto (uses current git branch + commit message), --clear-cache, --skip-bundler, --environment <env> (server-side env vars).

Republish / roll back to previous update (MUTATION)

npx eas update:republish --group <GROUP_ID> --non-interactive [--json]

Rolls back by republishing a previous update group. Can target via --channel, --branch, or --group. Supports --destination-branch/--destination-channel for cross-branch republish. Supports --rollout-percentage.

Roll back to embedded (MUTATION)

npx eas update:roll-back-to-embedded --branch <branch> --platform <platform> --non-interactive

Reverts users to the JS bundle embedded in the native binary. Use when an OTA update is broken and no previous update is safe.

Edit update rollout percentage (MUTATION)

npx eas update:edit <GROUP_ID> --rollout-percentage <1-100> --non-interactive [--json]

Adjust the rollout percentage of an existing update group.

Revert a rollout update (MUTATION)

npx eas update:revert-update-rollout --group <GROUP_ID> --non-interactive [--json]

Reverts a rollout update. Can target via --channel, --branch, or --group.

Delete an update group (MUTATION)

npx eas update:delete <GROUP_ID> --non-interactive [--json]

Permanently deletes all updates in a group.

Channels

Channels map to branches and control which updates users receive.

List all channels

npx eas channel:list --non-interactive [--json]

View a specific channel

npx eas channel:view <NAME> --non-interactive [--json]

Create a channel (MUTATION)

npx eas channel:create <NAME> --non-interactive [--json]

Point channel to a different branch (MUTATION)

npx eas channel:edit <NAME> --branch <branch> --non-interactive [--json]

Pause / resume a channel (MUTATION)

npx eas channel:pause <NAME> --non-interactive [--json]
npx eas channel:resume <NAME> --non-interactive [--json]

Pausing stops sending updates to users on that channel.

Channel rollout (MUTATION)

npx eas channel:rollout <CHANNEL> --action create --branch <branch> --percent <1-100> --non-interactive [--json]
npx eas channel:rollout <CHANNEL> --action edit --percent <new-pct> --non-interactive [--json]
npx eas channel:rollout <CHANNEL> --action end --outcome republish-and-revert|revert --non-interactive [--json]
npx eas channel:rollout <CHANNEL> --action view --non-interactive [--json]

Incrementally roll a new branch out on a channel. Actions: create, edit, end, view.

Delete a channel (MUTATION)

npx eas channel:delete <NAME> --non-interactive [--json]

Branches

Branches hold update groups. Each channel points to one branch.

List / view / create / rename / delete

npx eas branch:list --non-interactive [--json]
npx eas branch:view <NAME> --non-interactive [--json]
npx eas branch:create <NAME> --non-interactive [--json]        # MUTATION
npx eas branch:rename --from <old> --to <new> --non-interactive [--json]  # MUTATION
npx eas branch:delete <NAME> --non-interactive [--json]        # MUTATION

Builds

Trigger and monitor native app builds on EAS infrastructure.

List builds

npx eas build:list --platform <ios|android|all> --limit <n> --non-interactive [--json]

Key filters: --status (new|in-queue|in-progress|errored|finished|canceled), --distribution (store|internal|simulator), --channel, --build-profile, --app-version, --runtime-version, --fingerprint-hash.

View a specific build

npx eas build:view <BUILD_ID> [--json]

To extract build log URLs, use --json and read the logFiles array.

Trigger a build (MUTATION)

npx eas build --platform <ios|android|all> --profile <profile> --non-interactive [--json]

Key flags: --profile (from eas.json, defaults to "production"), --message, --clear-cache, --auto-submit / --auto-submit-with-profile, --no-wait, --what-to-test (TestFlight description, iOS only).

Cancel a build (MUTATION)

npx eas build:cancel <BUILD_ID> --non-interactive [--json]

Submissions

Submit completed builds to App Store or Google Play.

Submit a build (MUTATION)

npx eas submit --platform <ios|android|all> --profile <profile> --non-interactive

Key flags: --latest (submit latest build), --id <BUILD_ID> (specific build), --path (local file), --url (archive URL), --profile (from eas.json), --what-to-test (TestFlight, iOS only), --groups (TestFlight internal groups, iOS only).

Common Patterns

Check current OTA status for production

npx eas update:list --branch production --limit 5 --non-interactive

Publish OTA update to production with gradual rollout

npx eas update --branch production --message "fix: description" --platform all --rollout-percentage 25 --non-interactive

Emergency rollback

# Option 1: Republish a known-good previous update
npx eas update:republish --group <GOOD_GROUP_ID> --non-interactive

# Option 2: Roll back to the embedded binary bundle
npx eas update:roll-back-to-embedded --branch production --platform all --non-interactive

Full ship cycle: build, submit, OTA

# 1. Trigger production build
npx eas build --platform ios --profile production --auto-submit --non-interactive

# 2. After build completes, publish OTA update
npx eas update --branch production --message "v1.x.x release" --platform all --non-interactive

Troubleshooting

Authentication

If commands fail with authentication errors, verify login status:

npx eas whoami --non-interactive

If not authenticated, run npx eas login --non-interactive (requires EXPO_TOKEN env var) or direct the user to run npx eas login interactively.

Runtime version mismatch

OTA updates only deliver to builds with a matching runtime version. If an update appears published but users don't receive it, compare the update's runtime version against the installed build's runtime version.

# Check update runtime versions
npx eas update:list --branch production --limit 3 --non-interactive --json

# Check build runtime versions
npx eas build:list --platform ios --limit 3 --non-interactive --json

The runtimeVersion field must match between update and build.

Fingerprint drift

When native dependencies change (new native modules, SDK upgrade), the fingerprint hash changes. Use fingerprint comparison to determine if a new native build is required:

npx eas fingerprint:compare --non-interactive --json

Same fingerprint = OTA update is safe. Different fingerprint = new native build required. See references/webhooks-fingerprints.md for details.

Update not appearing

If an update was published but users don't see it:

1. Verify the update exists: npx eas update:list --branch production --limit 1 --non-interactive
2. Check the channel points to the correct branch: npx eas channel:view production --non-interactive
3. Verify runtime version matches the installed build
4. Check if the channel is paused: look for isPaused: true in channel view output
5. If using rollout, verify the rollout percentage: npx eas update:view <GROUP_ID> --json
