1 Introduction

Zero is a handy web framework based on koa.js. It improves your application development greatly by providing a bahavior-based module system, which makes module more reusable, and plenty of ready-to-use community modules.

2 Quick start

Let's try to install a blog system twenty based on zero.

>  npm install zero -g
>  zero new blog
>  cd blog
>  zero install twenty

...waiting for twenty install...

>  cp modules/twenty/config.sample.js modules/twenty/config.js
>  node app

For further information to use the blog, please visit

Developer are strongly suggested to install dev tool(it is a module too) to explore the system.

>  zero install dev //at root of your application

Simply visit http://localhost:3000/dev/index.html to open dev tool. You should see something like this:


Zero dev tool is very powerful, you can checkout model definitions, mock any request to view the event fire stack and even edit event handler's code at real-time. Try it you self!

Other awesome modules(or package) to play with:

  • Nine A GTD application integrated with tomato clock. Remember remove twenty before install this one, this module use multiple user system which may conflict with twenty.
  • Color A simple application for you to create your own color wall. Conflict with twenty too.

You may notice that there's no difference between a module and a application package, so mostly different application can exist at same time.

3 basic usage

3.1 Creating application

Run zero new <app_name> in any directory.

3.2 Installing zero module

Simply execute zero install <module_name> in root of you application.

3.3 Creating zero module

Zero module follow the standard npm package rules, the only restrict is that you should name your module name start with zero- in package.json.

3.4 Using other zero module as dependency

Declare zero dependency in package.json like:


When zero start, module's instance will be passed to its dependency's expand method, so extra behavior can be extend to it. Visit to checkout available module's and their usage.
