Dependency Injection

:::info Coming Soon Detailed dependency injection documentation is under development. :::

Zelt uses needle-di under the hood for dependency injection, providing a lightweight and type-safe DI container.

Quick Overview

import { Injectable, inject } from '@zeltjs/core';

@Injectable()
export class DatabaseService {
  query(sql: string) {
    // ...
  }
}

@Injectable()
export class UserRepository {
  constructor(private db = inject(DatabaseService)) {}

  findAll() {
    return this.db.query('SELECT * FROM users');
  }
}

See the Services documentation for practical usage patterns.
