Injectra

Injectra is a small dependency injection framework for Node.js and TypeScript.

The package is in early development. The public API is not stable yet.

Installation

npm install injectra

Requirements

Injectra currently targets Node.js 24 or higher.

{
  "engines": {
    "node": ">=24.0.0"
  }
}

Usage

Injectra is published as an ESM package.

import { INJECTRA_VERSION } from 'injectra'

console.log(INJECTRA_VERSION)

Current public API

At the moment, the package exposes only a minimal public entrypoint:

INJECTRA_VERSION

Future versions will provide the main dependency injection API:

import { Container, Injectable, Inject, Module } from 'injectra'

TypeScript

The package includes TypeScript declarations.

No additional type packages are required.

Decorator metadata

Injectra depends on reflect-metadata.

The package imports it from the public entrypoint, so users do not need to import it manually for the current API.

Future decorator-based APIs may require TypeScript decorator options in the consumer project:

{
  "compilerOptions": {
    "experimentalDecorators": true,
    "emitDecoratorMetadata": true
  }
}

Package format

Injectra is distributed as an ESM package.

import { INJECTRA_VERSION } from 'injectra'

CommonJS require() is not supported yet.
