Elucidsoft announces the initial release of OriJS, an open-source TypeScript backend web framework engineered specifically for the Bun runtime.
OriJS delivers the structural discipline of NestJS, including modular organization, dependency injection, controllers, guards, and interceptors, without the runtime overhead or debugging complexity of experimental TypeScript decorators and reflect-metadata.
Philosophy and architecture
OriJS borrows proven architectural patterns across the TypeScript ecosystem:
- From NestJS: Inversion of control, modular providers, route guards, and execution interceptors.
- From Elysia & Hono: End-to-end type safety, composable middleware, and blazing-fast HTTP throughput on Bun.
- From Fastify & Pino: Schema-based request validation and high-performance structured JSON logging.
Instead of relying on unstable reflection metadata, OriJS configures modules and dependencies via an explicit, type-safe fluent builder API. Service injection graphs are visible in code, inspectable at build time, and easy to mock during unit testing.
Pluggable provider ecosystem
OriJS separates core orchestration from infrastructure dependencies through swappable provider packages:
@orijs/validation: TypeBox-based schema validation for requests and responses.@orijs/config: Validated environment configuration with secret management support.@orijs/cache&@orijs/cache-redis: Singleflight caching with Redis or in-memory backing.@orijs/events&@orijs/bullmq: Type-safe event broadcasting and background queue execution.@orijs/workflows: Saga-pattern distributed workflow orchestration with automated compensation steps.@orijs/websocket: Horizontally scalable WebSocket pub/sub with Redis adapters.@orijs/logging: High-throughput structured logging with child logger context.
OriJS is open source under the MIT license and hosted at github.com/upstat-io/orijs. Documentation and guides are available at orijs.org.
