Lark-MVC

A manager for MVC design.

How to use

  • see example/koa.js in source code

First define mvc and some module, then dispatch works.

const MVC = require('lark-mvc');
const mvc = new MVC();    // using default configs

Define a Page class inherits from mvc.Page as an controller

class ShowIntroduction extends mvc.Page {
    async main(ctx, next) {
        const person = new this.mvc.Data.Person('Sun Haohao');
        ctx.body = await this.mvc.View.render(person);
        await next();
    }
}

Define a Data Person as model

class Person extends mvc.Data {
    constructor(name) {
        super();
        this.name = name;
    }
    async introduction() {
        return new Promise(resolve => setTimeout(() => resolve(`Hello, I am ${this.name}`), 1000));
    }
}

Define a view

class MyView extends mvc.View {
    async render(person) {
        return await person.introduction();
    }
}

Register them

const app = new Koa();
const mvc = new LarkMVC();

mvc.use(ShowIntroduction).use(Person).use(MyView);
app.use(async (...args) => {
    const showIntroduction = new ShowIntroduction();
    await showIntroduction.main(...args);
}).listen(3000);
