Is StreetJS or Fastify faster?

Both target low overhead on Node core HTTP. Differences are workload-specific; benchmark your own routes, payloads, and database.

StreetJS vs Fastify

Q: Does StreetJS support JSON Schema validation like Fastify?

StreetJS validates via @Validate schemas and generates OpenAPI. Fastify's JSON-Schema-centric pipeline offers more granular serialization tuning.

In one line: Both are performance-minded Node frameworks; Fastify is a fast router with a rich plugin system, while StreetJS bundles DI, database, auth, and realtime as first-class, typed building blocks.

At a glance

	StreetJS	Fastify
Focus	Integrated backend platform	High-performance router + plugins
Routing	Decorator controllers	Schema-based route definitions
Dependency injection	Built-in	Via plugins/decorators
Database	Native PG driver, MySQL, SQLite, ORM	Bring your own (plugins)
Validation	`@Validate`	JSON Schema (built in, excellent)
Auth / RBAC / MFA	Built in	Plugins
WebSockets	Built in + channels	`@fastify/websocket` plugin
Dependencies	Dependency-light core	Lean core + chosen plugins
Ecosystem & community	Smaller / younger	Large, very active

Where Fastify wins

Schema-first validation & serialization is a standout — fast JSON Schema validation and serialization are core strengths.
Mature plugin ecosystem and a large, active community.
Proven at scale across many production deployments.

Where StreetJS wins

Batteries included: DI, ORM, auth (JWT/sessions/RBAC/MFA), and realtime ship together — fewer plugins to choose, wire, and keep compatible.
TypeScript-native ergonomics: decorator controllers and a typed context.
Full-stack: a typed client SDK and framework hooks plus street create --frontend scaffolding.

Honest tradeoffs

Fastify has a larger ecosystem and a longer track record, and its schema-based validation/serialization is best-in-class. If you want to compose your own stack around a fast core with proven plugins, Fastify is excellent. If you prefer an integrated, typed platform with less assembly, StreetJS fits better.

Migrating from Fastify

Fastify route handlers and hooks map to StreetJS controllers and middleware. See the Fastify → StreetJS migration guide.
