@injitools/core

Core of the Inji framework: a declarative router with DTO/Zod validation, OpenAPI 3.1 generation, middleware wiring and an error hierarchy. No database dependency.

Part of the Inji monorepo.

Install

npm install @injitools/core

Requires experimentalDecorators + emitDecoratorMetadata in your tsconfig.json.

Usage

import {Router, Get, Response, InjiRouter} from "@injitools/core";

@Router("hello")
class HelloApi {
  @Get()
  @Response(200, String)
  index() { return "Hello"; }
}

const router = new InjiRouter([HelloApi]);
app.use(router.toExpressRouter()); // Express router
router.toOpenApi();                // OpenAPI 3.1 spec

Entry points

• @injitools/core — router, RequestDto/ResponseDto and validation decorators, error middleware, buildOpenApiDocument (router → OpenAPI 3.1 doc), and createApiClient/createFetchClient (an inter-server client between backends).
• @injitools/core/codegen — emitSchema (router → generated schema.gen.ts TS interfaces for frontends). A separate subpath (uses node:fs) so runtime servers don't pull in the generator. Needs only ORM metadata — run it offline via TypeORM's buildMetadatas(), no DB connection.
• @injitools/core/runtime — env, Config, loadEnv, environment helpers.
• @injitools/core/lifecycle — makeProcess, graceful shutdown.

See the monorepo README for the full picture.
