Deploy to Firebase Hosting

Build and deploy the catalog UI and/or docs site to Firebase Hosting.

Arguments

• $ARGUMENTS may contain:
• --dry-run — Build only, skip deploy. Show what would be deployed.
• --target catalog — Deploy only the catalog UI
• --target docs — Deploy only the docs site
• --target all — Deploy both (default)
• No arguments = build and deploy all targets

Workflow

1. Parse Arguments

Extract flags from $ARGUMENTS:

• Check for --dry-run flag
• Check for --target <value> (default: all)

2. Validate Prerequisites

Run these checks before proceeding:

# Check Firebase CLI is installed
which firebase || echo "ERROR: Firebase CLI not installed. Run: npm install -g firebase-tools"

# Check Firebase auth
firebase projects:list --limit 1 2>&1 || echo "ERROR: Not authenticated. Run: firebase login"

# Check firebase.json exists
test -f firebase.json || echo "ERROR: firebase.json not found in project root"

If any check fails, report the error and stop.

3. Build

Based on --target:

Catalog UI (target = catalog or all):

cd catalog-ui && npm ci && npm run build

Report build output size: du -sh catalog-ui/dist

Docs Site (target = docs or all):

cd docs-site && npm ci && npm run build

Report build output size: du -sh docs-site/dist

4. Deploy (skip if --dry-run)

firebase deploy --only hosting

If targeting a specific site:

firebase deploy --only hosting:catalog
# or
firebase deploy --only hosting:docs

5. Report

On dry-run:

**Dry Run Complete**

| Target | Build | Size |
|--------|-------|------|
| Catalog UI | OK | X MB |
| Docs Site | OK | X MB |

Ready to deploy. Run `/deploy` (without --dry-run) to push to Firebase.

On deploy:

**Deployed Successfully**

| Target | URL |
|--------|-----|
| Catalog UI | https://architecture-catalog.web.app |
| Docs Site | https://docs-architecture-catalog.web.app |

Firebase project: ea-toolkit-demo-ac513

Error Handling

• If build fails, show the error output and stop. Do not deploy a broken build.
• If deploy fails, show the Firebase error. Common fix: firebase login to re-authenticate.
• If node_modules/ is missing, npm ci handles it automatically.

Notes

• The CI/CD pipeline (.github/workflows/deploy.yml) auto-deploys on push to main. This skill is for manual/preview deployments.
• Firebase project ID: ea-toolkit-demo-ac513 (from .firebaserc)
• Hosting targets: catalog → architecture-catalog, docs → docs-architecture-catalog
