injecute

Lightweight, type-safe, decorator-free dependency injection container for TypeScript.

Dependencies are declared explicitly as keys. The container's type grows with every registration, so get() results and factory parameters are fully typed, and a typo in a dependency key is a compile error.

Install: npm i injecute · deno add npm:injecute · bun add injecute, or import from a CDN: https://esm.sh/injecute.

Example

Register and resolve services

import { DIContainer } from 'injecute';

class UserRepository {
  constructor(readonly dbUrl: string) {}
}

const container = new DIContainer()
  .addInstance('dbUrl', 'postgres://localhost/app')
  .addSingleton('users', UserRepository, ['dbUrl']);

const users = container.get('users'); // typed as UserRepository
