node-firefox-forward-ports Build Status

Forward local ports to remote debugging interfaces on connected Firefox OS devices

Install with NPM

This is part of the node-firefox project.

Firefox OS devices offer a Remote Debugging service on a local network socket. This can be forwarded to a host computer over USB using ADB. This module takes care of that as necessary, reusing forwarded ports when possible.

Installation

From git

git clone https://github.com/mozilla/node-firefox-forward-ports.git
cd node-firefox-forward-ports
npm install

If you want to update later on:

cd node-firefox-forward-ports
git pull origin master
npm install

npm

npm install node-firefox-forward-ports

Usage

var forwardPorts = require('node-firefox-forward-ports');
 
// Forwards ports as necessary, while reusing existing ports.
// Returns the list of devices annotated with details on forwarded ports.
forwardPorts([
  {id: '3739ced5'},
  {id: 'full_keon'},
  {id: 'full_unagi'}
]).then(function(results) {
  console.log(results);
}).catch(function(err) {
  console.error(err);
});
 
// forwardPorts() can also accept an options object, for future expansion
// when additional options are supported.
forwardPorts({
  devices: [
    {id: '3739ced5'},
    {id: 'full_keon'},
    {id: 'full_unagi'}
  ]
}).then(function(results) {
  console.log(results);
}).catch(function(err) {
  console.error(err);
});
 

Example

This example uses node-firefox-find-devices to first assemble a list of connected Firefox OS devices. The output of findDevices() is basically what forwardPorts() expects for its devices option.

var findDevices = require('node-firefox-find-devices');
var forwardPorts = require('node-firefox-forward-ports');
 
findDevices().then(forwardPorts).then(function(results) {
  console.log(results);
});

This example would result in output like the following, which consists of the output of findDevices() altered to include a list of forward ports for each device.

[
  {
    "id": "3739ced5",
    "type": "device",
    "isFirefoxOS": true,
    "ports": [
      {
        "local": "tcp:8001",
        "remote": "localfilesystem:/data/local/debugger-socket",
        "port": "8001"
      }
    ]
  }
]

The listing of each device returned from findDevices() will be annotated with a new ports property. This is a list of details on each port forwarded to the device.

The local property contains the local side of the port forward. If this is a TCP/IP port, then its numerical port can be found in the port property.

The remote property contains the remote side of the port forward, useful for filtering and selecting particular kinds of forwarded ports. Currently, this module only supports Firefox remote debugging sockets - but that could expand in the future.

Running the tests

After installing, you can simply run the following from the module folder:

npm test

To add a new unit test file, create a new file in the tests/unit folder. Any file that matches test.*.js will be run as a test by the appropriate test runner, based on the folder location.

We use gulp behind the scenes to run the test; if you don't have it installed globally you can use npm gulp from inside the project's root folder to run gulp.

Code quality and style

Because we have multiple contributors working on our projects, we value consistent code styles. It makes it easier to read code written by many people! :-)

Our tests include unit tests as well as code quality ("linting") tests that make sure our test pass a style guide and JSHint. Instead of submitting code with the wrong indentation or a different style, run the tests and you will be told where your code quality/style differs from ours and instructions on how to fix it.
