AWS Amplify Full-Stack

Full-stack framework for React/Next/Vue with auth, data, storage, hosting — CLI + libraries.

AWSIntermediate

Why

Amplify wires frontend to AWS — Cognito auth, AppSync GraphQL, S3 storage, CloudFront hosting — with one CLI. Great for rapid full-stack apps without deep AWS knowledge.

AWS is used by 48% of developers and holds 30% cloud market share (Synergy Research Q4 2024). AWS offers 200+ services with a $115B annual run rate, and the Free Tier covers 750 hours/month of EC2 + Lambda for the first 12 months.

When

Use for rapid full-stack web/mobile apps with auth + data + storage. Avoid for complex custom infra (use CDK) or non-AWS backends.

How

1. Init — amplify init, configure project + env 2. Auth — amplify add auth, Cognito user pool, social login 3. API — amplify add api, GraphQL (AppSync) or REST (API Gateway) 4. Storage — amplify add storage, S3 for uploads 5. Hosting — amplify add hosting, CloudFront + S3, CI/CD on push 6. Push — amplify push, deploys backend 7. Pull — amplify pull, sync backend to local 8. Libraries — amplify-js v6 modular, auth/data/storage clients

Example

# Add auth + GraphQL API amplify add auth # choose Default configuration amplify add api # choose GraphQL, edit schema.graphql amplify push // schema.graphql type Todo @model @auth(rules: [{ allow: owner }]) { id: ID! title: String! done: Boolean } // React — use generated hooks import { withAuthenticator } from "@aws-amplify/ui-react"; import { generateClient } from "aws-amplify/api"; const client = generateClient(); const { data } = await client.models.Todo.list(); const todo = await client.models.Todo.create({ title: "Learn Amplify" });

Common Problems

⚠amplify push overwrites — use amplify env for separate environments
⚠Generated code stale — re-run amplify codegen after schema changes
⚠Cognito limits — 50 user pools per account, request increase if needed

Best Practices

✓Use amplify env for stages — dev/staging/prod backends, isolated data
✓Prefer GraphQL over REST — type safety, real-time subscriptions, less code
✓Use @auth directives — Cognito groups, owner-based, public read patterns
