citizenos/etherpad-lite-client-js

JavaScript wrapper for the Etherpad Lite API

Etherpad Lite API

Supports all the API calls described in the Etherpad Lite API page.

Setup

You can install it via NPM:

$ npm install etherpad-lite-client

or add it to your package.json dependencies:

"etherpad-lite-client": "0.9.x"

Usage

api = require('etherpad-lite-client')
etherpad = api.connect({
  apikey: 'UcCGa6fPpkLflvPVBysOKs9eeuWV08Ul',
  host: 'localhost',
  port: 9001,
})

etherpad.createGroup(function(error, data) {
  if(error) console.error('Error creating group: ' + error.message)
  else console.log('New group created: ' + data.groupID)
})

Certain API calls require that you pass some arguments:

var args = {
  groupID: 'g.yJPG7ywIW6zPEQla',
  padName: 'testpad',
  text: 'Hello world!',
}
etherpad.createGroupPad(args, function(error, data) {
  if(error) console.error('Error creating pad: ' + error.message)
  else console.log('New pad created: ' + data.padID)
})

Any options passed to api.connect will be passed to http(s).request as options so you can specify any .request options. All options are described https://nodejs.org/api/https.html#https_https_request_options_callback

For example, if you have Etherpad configured locally, running SSL on 9001 with self signed certificates, you can configure client as follows:

etherpad = api.connect({
  apikey: 'UcCGa6fPpkLflvPVBysOKs9eeuWV08Ul',
  host: 'localhost',
  port: 9001,
  ssl: true,
  rejectUnauthorized: false
})

Where ssl switches EP client to HTTPS client and rejectUnauthorized: false disables CA certificate check. For more options see https://nodejs.org/api/https.html#https_https_request_options_callback.

Callback & Returned Data

The callback function should look like this:

function(error, data) {
  if(error) {
    // handle error using error.code and error.message
  }

  // some code
}

The callback function takes two argument: error and data.

error

error is null if everything is fine. Otherwise it's a JavaScript object that describes what's wrong.

It has two attributes: code and message:

• error.code
  • 1 wrong parameters
  • 2 internal error
  • 3 no such function
  • 4 no or wrong API Key
  • -1 there was problem with calling Etherpad API
• error.message: a text representation of the error

data

data is a JavaScript object from the Etherpad response or null (on error).

Development

The author prefers pull requests for changes. To do this, first fork the repository, then checkout your fork and apply your changes. Then create your pull request. Please create one pull request per change.

Do not change main.js but instead only main.coffee, use "npm i [email protected] -g" in order to prevent too many unwanted and untested changes. After you made your changes to main.coffee in your fork, on linux run "cake build" in the root of your project, it will generate a new main.js file. On windows you can compile by issuing "coffee --compile main.coffee" command.
