container
    .addAsFunction(userRepository)
    .addAsClass(UserService)
    .addAsValue('cache', cache)
    .addAsFunction(getUsersUseCase);

const useCase = container.factoryContainer().getUsersUseCase;

Express middleware

To use HerbsJS with express serve you can use useHerbsDi middleware to configure container like bellow:

const app = express()
const port = 3000

app.use(useHerbsDi(injection))

app.get('/', async (req, res) => {
    const { getUsersUseCase } = req.injection;
    const ret = await getUsersUseCase.run({ name: 'Jhon' });
    if (ret.isOk) {
        res.send({ users: ret.value });
        return;
    }
    res.send({ error: ret.err })
})

Scripts

• dev:console to run an example di container console
• dev:express to run an API with express middleware for the di container
• dev:gql to run an api with graphql middleware for the di container (under construction)
