@cub/cub

a web framework for fibjs

Install

$ npm i @cub/cub --save

Quick Start

const Cub = require('@cub/cub');

const cub = new Cub();

cub.register(ctx => {
  ctx.body = 'Hello World!';
});

cub.listen(8000);

Usage

• multi-register

Register function can be invoked many times to accept interceptor. All these registered interceptors will be executed one by one.

cub.register(ctx => {
  ctx.body = 'Hello';
});

cub.register(ctx => {
  ctx.body += ' World!';
});

• stop execute register

If you want to stop running the flowing interceptor, just return false(only false accept) in the current interceptor.

cub.register(ctx => {
  ctx.body = 'Hello ';
  return false; // only `false` accept
});

cub.register(ctx => {
  ctx.body += ' World!';
});

• If you want to execute some logic after the last interceptor has been invoked like koa design, you register a an instance of BaseInterceptor.

const BaseInterceptor = Cub.BaseInterceptor;

cub.register(new class extends BaseInterceptor {
  before (ctx){
    ctx.body = 'Hello';
  }

  after (ctx){
    ctx.body += ' World!';
  }
});
