MicroBlitz: Node.js Microservice Framework for Fast Dynamic APIs

MicroBlitz is a Node.js microservice framework designed to create dynamic APIs quickly while maximizing performance and minimizing resource usage.

Architecture & Technical Design

Node.js Core: Non-blocking, event-driven I/O allows handling multiple concurrent requests efficiently.
Fastify over Express:
- Faster request handling and lower latency
- Minimal memory usage for small-scale deployments
- Schema-based validation for robust endpoints
Multicore Support: Uses Node.js cluster module to fully utilize CPU cores, improving throughput and responsiveness.

Functions-Based API Generation

MicroBlitz uses a convention-over-configuration model:

Drop .js files in functions/ → automatic API creation
Hot-reload support on server restart
Reduces boilerplate and accelerates rapid prototyping

This architecture is ideal for creating small, fast microservices or dynamic test APIs on personal servers.

Performance Optimizations

Async/await handlers for minimal overhead
Clustered workers for parallel request processing
Streamlined JSON responses to reduce latency
Lightweight routing without unnecessary middleware

These optimizations ensure high performance even on low-powered hardware.

Developer Use Cases

Test & Dev APIs – instant endpoints for integration and QA.
Client Demonstrations – temporary microservices for demos.
Personal Microservices – internal tools, automation scripts, or small SaaS endpoints.

Key Takeaways

Dynamic API creation made simple with Node.js and Fastify
Efficient multicore handling for low-latency endpoints
Developer-first approach with functions-folder structure
Lightweight and scalable, perfect for dev/test and personal servers

MicroBlitz provides a technical, practical solution for developers who need fast, flexible, and efficient API microservices.
