Overview
The Service Container is a comprehensive TypeScript/JavaScript module designed to manage and maintain services in a structured and efficient manner. It provides functionalities such as service registration, resolution, disposal, and automatic loading of services from a specified directory. The module is built to be versatile, handling both class-based and functional services, with support for lazy loading, custom initialization, and disposal.
Features
- Service Registration: Dynamically register services with unique names.
- Service Resolution: Resolve and retrieve registered services as needed.
- Service Disposal: Dispose of services individually or collectively.
- Automatic Service Loading: Automatically load services from a specified directory.
- Lazy Loading: Option to lazily load services to optimize performance.
- Custom Initializers and Disposers: Execute custom logic during service initialization or disposal.
- Logging and Error Handling: Built-in logging capabilities and robust error handling.
- Typed Services: Specify what each of your services will resolve as.
Installation
npm/bun/yarn install @neos/container
Usage
Importing Container
import { Container } from "@neos/container";
Creating a Container Instance
const container = new Container(options);
Registering Services
While the register
method takes an array and registers each item... its not recommended to register to many things in a row. Instead use the auto-load feature.
await container.register([
{
name: "ServiceName",
service: ServiceClass,
options: {
/* ... */
},
},
]);
Resolving Services
await container.resolve("ServiceName").then((serviceInstance) => {
// Use serviceInstance
});
Disposing Services
await container.dispose("ServiceName");
Auto-Loading Services
// index.ts
container.autoLoad("/path/to/services");
// someServiceFile.ts
export {
name: "someName",
service: someService,
options: {
logging: (container, options) => {
console.log(`Loaded: ${options.name}`);
},
},
} as AutoLoadServiceOptions;
Typing Services
// services.d.ts
import '@neos/container';
declare module "@neos/container" {
interface ServiceMap {
// Services here:
ServiceName: ServiceType;
}
}
