Is there a recommended library to do dependency injection in Deno?

I'm creating a Rest API with the repository and controllers pattern but my code in the main.ts file keeps getting bigger and bigger
// Repositories
const animeFavoritesRepo = new MongoAnimeFavoritesRepository(mongoDatabase);
const animesRepo = new MongoAnimesRepository(mongoDatabase);
const usersRepo = new MongoUsersRepository(mongoDatabase);
// .... more repos

// Routes
// I'm injectin the controllers and repos
const auth = new AuthRoutes(new AuthController(usersRepo), usersRepo).router();
app.use(auth.routes());
app.use(auth.allowedMethods());
// ... more routes
// Repositories
const animeFavoritesRepo = new MongoAnimeFavoritesRepository(mongoDatabase);
const animesRepo = new MongoAnimesRepository(mongoDatabase);
const usersRepo = new MongoUsersRepository(mongoDatabase);
// .... more repos

// Routes
// I'm injectin the controllers and repos
const auth = new AuthRoutes(new AuthController(usersRepo), usersRepo).router();
app.use(auth.routes());
app.use(auth.allowedMethods());
// ... more routes

You can use Danet and leverage its custom DI system. It even provides a CLI to bundle for Deploy, a guide on how to do so manually, and a github action ready to use.
