Dead simple service and config container, with lazy initialization and strong typings.
import { ServiceContainer } from 'service-service'
class ExampleService {
private readonly name: string
constructor(name: string, options: { a: string }) {
this.name = name
}
getName() {
return this.name
}
}
export interface AppConfig {
name: string
}
export const container = new ServiceContainer<AppConfig>()
// specify configuration values:
container.configure('name', 'Example App')
// get configuration values:
container.config('name')
// define services, pass `constructor` params as array:
container.define(ExampleService, [
'the-name',
{
a: 'a-value',
},
])
// provide params as function, for lazy execution (on first `use`)
container.define(ExampleService, () => [
'the-name',
{
a: 'a-value',
},
])
// use the service:
const service = container.use(ExampleService)
service.getName() // will return `the-name`ESM only package
