nut-ioc-typescript-simple-demo

TypeScript Demo Project using with nut-ioc framework

nut-ioc.d.ts file should be copied in root folder of your repository and then tsconfig.json file should be updated as "include": [ "nut-ioc.d.ts" ] or use this one.

Usage

There are two classes named GreetingHelper.ts and EnglishGreeting.ts and EnglishGreeting.ts want to use GreetingHelper.ts as a dependency so it can be required via constructor function.

./src/GreetingHelper.ts

import { Direction } from "readline";
import IGreetingHelper from "./IGreetingHelper";

export default class GreetingHelper implements IGreetingHelper {
    getFullName(firstName: string, lastName: string, direction: Direction) {
        return `${firstName} ${lastName}: Direction=> ${direction}`;
    }
}

Notice that constructor has GreetingHelper parameter so nut-ioc can inject it in runtime..

./src/EnglishGreeting.ts

import { Direction } from "./Direction";
import IGreeting from "./IGreeting";
import IGreetingHelper from "./IGreetingHelper";

export default class EnglishGreeting implements IGreeting {
    constructor(private GreetingHelper: IGreetingHelper) { }

    getFullName(firstName: string, lastName: string): string {
        return this.GreetingHelper.getFullName(firstName, lastName, Direction.Down);
    }

    sayHello(firstName: string, lastName: string): string {
        return `Hello ${this.GreetingHelper.getFullName(firstName, lastName, Direction.Down)}`;
    }
}
