How to import singletons

[ashokkumar88]

I am using Adonis 6. In app_provider.ts I have created a singleton like below. I want to import it in a controller.

this.app.container.singleton('App/GraphQL', () => graphql_middlewire);

I want to import the 'App/GraphQL' singleton in a controller.

Hi @ashokkumar88,

Here is a example with a provider:

import type { ApplicationService } from '@adonisjs/core/types'
import Stripe from 'stripe'
import StripeConfig from '#config/stripe'

export default class StripeProvider {
  constructor(protected app: ApplicationService) {}

  register() {
    this.app.container.singleton('max/stripe', async () => {
      return new Stripe(StripeConfig.secretKey)
    })
  }
}

declare module '@adonisjs/core/types' {
  interface ContainerBindings {
    'max/stripe': Stripe
  }
}

And inside your controller you can do that:

const stripe = await app.container.make('max/stripe')
