MVC

This page is a guide to use the MVC pattern with Byte.

Controllers

Every Byte instance is equivalent to a controller.

// Don't do this
app.get('/', Controller.index);

// Do this instead
app.get('/', (ctx) => {
    // Write the handler code here
    // Does not require manual typings
});

Services

Some piece of code that can be decoupled from the controller should be separated into a service:

Service

export const getNumbers = query.get('number', {
    type: 'number',
    maxItems: 5000
});

Controller

import * as service from './service';

app.get('/numbers', (ctx) => ctx.body(
    service.getNumbers(ctx).join()
));

Models

Models can be handled using states in Byte:

Model

export const validateBody = Byte.handle((ctx) => {
    // Return a result or a Response object
});

Controller

import * as model from './model';

app.state('body', model.validateBody)
    .post('/json', (ctx) => {
        // Use ctx.body here
    });
