AWS Blocks Application Development

Package naming: All packages are published under the @aws-blocks scope (e.g., @aws-blocks/core, @aws-blocks/blocks, @aws-blocks/bb-kv-store).

Overview

AWS Blocks is an Infrastructure-from-Code framework where Building Blocks bundle CDK, SDK, and local mocks into a single API. It provides 18+ Building Blocks covering storage, authentication, real-time communication, background jobs, file management, AI/search, email, and observability — all working locally without AWS credentials.

Key characteristics:

• One aws-blocks/ directory defines the entire backend
• Frontend imports are fully typed — no client generation needed
• All Building Blocks work locally without AWS (mocks persist to .bb-data/)
• Deploy ephemeral, individual testing environments with npm run sandbox and long-lived environments with npm run deploy using least-privilege credentials
