Usage

npm i -D @kiyoshiro/ts-wire
npx ts-wire init # Create `src/wire.ts`

In src/wire.ts, you have to list values and classes you want to resolve dependencies.

import { BarRepository, db, FooController, FooRepository, FooService } from './foo'

export const providers = [db, FooRepository, BarRepository, FooService, FooController]

Then, you run a generate command.

npx ts-wire generate

You can see the following code in src/wire-generated.ts.

import { FooRepository, db, BarRepository, FooService, FooController } from './foo'

const fooRepository = new FooRepository(db)
const barRepository = new BarRepository(db)
const fooService = new FooService(fooRepository, barRepository)
const fooController = new FooController(fooService)
const leaves = { fooController }

export default leaves
