The next generation of lightweight collaborative online editing.

WARNING: This repository does not contain the code for what you see running on

The current code for Plunker is in the repositories listed below

Originally, Plunker was coded in a single repository with different sub-servers existing in the /servers path. The entire application was run on a single server.

However, with increasing popularity, reality decided to come hang out and make everyone's lives difficult. The solution was simple; since the components of Plunker were designed as 'sub-servers', it should be easy to split them out and run them separately. However, having different logical entities with different functions in the same repository doesn't make sense.

I decided to create separate repositories for each of the Plunker servers that are currently deployed on Nodejitsu. They are as follows:

Plunker component repositories

  • plunker_api The server that connects to a mongodb database and serves requests over a restful api.
  • plunker_www The server that is responsible for hosting and running the front-end that users see and touch everyday.
  • plunker-run-plugin The server that allows for previewing of plunks and temporary previews and also does the dynamic transpilation.
  • plunker_collab The server that serves the code necessary for collaborative coding as well as doing the actual operational transformation over a browserchannel connection.
  • plunker_embed The server that hosts the embedded views of plunks.

Plunker config files

Each server, once cloned locally, requires one or two config.json files to run.

Servers that use the environment-specific config files config.development.json and config.production.json:

  • plunker_api
  • plunker_www
  • plunker_run
  • plunker_collab

Only plunker_embed uses a single config.json file.

Sample configuration file:

Not all fields are required by each server, but if all are present no harm should come to any small animals.

  "host": "",
  "url": {
    "www": "",
    "collab": "",
    "api": "",
    "embed": "",
    "run": "",
    "carbonadsH": "OOPS, this is pretty specific to my current deploy",
    "carbonadsV": "OOPS, this is pretty specific to my current deploy"
  "port": 8080,
  "oauth": {
    "github": {
      "id": "series_of_random_chars",
      "secret": "longer_series_of_random_chars"

Everything below this point is out of date or incorrect!

Editor API

POST /edit/

You can send a POST request to /edit/ to bootstrap the editor with the basic structure of a plunk. The JSON format for this is described below.

  "description": "Description of Plunk",
  "tags": ["array", "of", "tags"],
  "files": [
      "filename": "index.html",
      "content": "<html><script src=\"script.js\"></script></html>"
      "filename": "script.js",
      "content": "alert('hello world');"
