What is deploying as one unit?
It is getting your whole app live together: the client, the server, and the database, configured to talk to each other in production. Whether it is one platform deploying a full-stack framework or coordinated services, the goal is a single, repeatable release of the complete app.
Why it matters
A feature is not done until users can reach it, and full-stack deploys have more moving parts than either half alone — build steps, environment config, database migrations, and the connections between them. Knowing how to ship the whole thing reliably is what turns your work into a running product.
What to learn
- Platforms for full-stack apps (Vercel, Railway, Fly, Render)
- Building client and server for production
- Running migrations as part of deploy
- Connecting to a managed production database
- Environment configuration per stage
- Zero-downtime deploys and health checks
- Rollback when a deploy goes wrong
Common pitfall
Deploying new code that expects a schema the production database does not have yet, because the migration was forgotten or ran in the wrong order. Make migrations part of the deploy pipeline, run them before the code that needs them, and keep them backward-compatible so old and new code can briefly coexist.

Practice
Deploy a full-stack app: build and host the client and server, connect a managed production database, run a migration as part of the deploy, and confirm the live app works end to end. Add a health check. Done when a push deploys the whole app and migrations run in the right order.
Outcomes
- Deploy client, server, and database together.
- Run migrations safely as part of the deploy.
- Configure environments per stage.
- Deploy with health checks and a rollback path.
