vo

Vo is a control flow library for minimalists.

Features

• Seamlessly supports promises, generators, synchronous & asynchronous functions.
• Vo is composable, allowing you to intuitively orchestrate complex work flows
• Easily catch and fix errors anywhere in the pipeline
• Returns a promise that you can yield on or "await"
• Supports both stack and pipeline task flow
• Tiny (4kb minified + gzip)
• Browser & server support
• Well-tested

Installation

• Node.js or Browserify: npm install vo
• Standalone: vo.js & vo.min

Getting Started

An updated guide will be available soon. For now, take a look at the tests for now.

Vo Runtime

Now you can run generators top-level with the runtime:

index.js

var res = yield superagent.get('http://google.com')
console.log(res.status) // 200
return res.status

vo index.js // 200

Things to keep in mind

Binding a generator function isn't consistently implemented yet

function * a () {
  // this === ctx
}

vo(a.bind(ctx))

The following will work on node 5 and latest chrome, but not on latest safari or node 4. Latest babel does not fix this problem.

Just to be safe, I'd install co-bind and do this instead:

var bind = require('co-bind')

function * a () {
  // this === ctx
}

vo(bind(a, ctx))

Test

We have a comprehensive test suite. Here's how you run it:

npm install
make test
