Scripts

Run custom commands at different stages of the deploy lifecycle.

Script Types

Script	When it runs	Common use
release	After dependencies install, before deploy	Build assets, compile code
predeploy	After release, before app starts	Run migrations, seed data
postdeploy	After app starts	Warm caches, health checks
destroy	When app is deleted	Clean up external resources

Configuration

apps:
  - name: myapp
    scripts:
      release:
        - npm run build
        - npm run typecheck
      predeploy:
        - npm run migrate
      postdeploy:
        - echo "Deployed successfully"
      destroy:
        - echo "Cleaning up"

Examples

Node.jsPython (Django)GoStatic Site

scripts:
  release:
    - npm ci
    - npm run build
  predeploy:
    - npx prisma migrate deploy

scripts:
  release:
    - pip install -r requirements.txt
  predeploy:
    - python manage.py migrate
    - python manage.py collectstatic --noinput

scripts:
  release:
    - go build -o server .

scripts:
  release:
    - npm run build
    - cp -r dist/* .

How They Work

1. Dependencies install — Plitho runs npm install or pip install automatically
2. release — Runs after dependencies are installed. Use for build steps.
3. predeploy — Runs after release, before the app starts. The app is not running yet.
4. postdeploy — Runs after the app starts. The app is live.
5. destroy — Runs when the app is deleted.

Warning

Scripts run with the same permissions as your app. Don't put secrets in scripts — use environment variables instead.
