This is a full featured bot for Gitter.im/FreeCodeCamp chat rooms.
Main features:
- integration with github FCC wiki
find(aliasexplain) command to show wiki pages- wrapper for commands
The CamperBot is integrated into various FreeCodeCamp chat rooms.
Join us in Gitter.im/FreeCodeCamp/camperbot to discuss about camperbot development!
Test the CamperBot in Gitter.im/FreeCodeCamp/camperbotPlayground room.
CamperBot was originally created by for Free Code Camp by @dcsan at RIKAI Labs, and is now maintained by our open source community.

CamperBot is a full featured chat bot for Gitter.im developed to integrate with the chat rooms for FreeCodeCamp — the largest online coding bootcamp in the world, where it serves more than 60,000 campers.
You can search for articles in a projects github wiki
Use explain to pull a wiki summary right into the chat:
Allow your users to send points to each other to say thanks @username
Based on scannable expressions, send messages into the chat.
Custom functions can easily be added. Check the System Overview
To run camperbot, you need Node.js.
To install Node, follow the instructions here
- To make your the local server automatically watch for file changes, install "nodemon" (you may need
sudo)
sudo npm install -g nodemon- To download the app, clone the repository the bot is in:
git clone https://github.com/FreeCodeCamp/camperbot.git- Run the following commands to run the app:
cd camperbot
cd nap
cp dot-EXAMPLE.env dot.env
npm install
nodemon app.js- That's it! The app should be running at http://localhost:7891.
You can now chat to your bot via Gitter.im at https://gitter.im/demobot/test
To install Node.js on Windows, follow these instructions.
- To make your the local server automatically watch for file changes, install "nodemon" in an administrator console.
npm install -g nodemon- To download the app, clone the repository the bot is in:
git clone https://github.com/FreeCodeCamp/camperbot.git- Run the following commands to run the app:
cd campberbot
cd nap
copy dot-EXAMPLE.env dot.env
npm install
nodemon app.js- That's it! The app should be running at http://localhost:7891.
You can now chat to your bot via Gitter.im at https://gitter.im/demobot/test
The dot.env file you copied above contains login info. This is using the shared "demobot" account so you may find yourself in a chatroom with other people using the same ID!
To setup your own gitter login info, you should create your own Gitter API key on their developer site, and replace the info in that .env file. Get your own API keys for gitter from: https://developer.gitter.im/apps
For more settings info, checkout the AppConfig.js and RoomData.js files. These define which rooms the bot will listen in to.
You may chat with us in the CamperBot Dev chat room if you have problems. camperbot chatroom.
There are other commands in bin for running tests with the right config files etc
To run the tests with the right configs
bin/test.shThe wiki content is pulled in from FCC's wiki using a git submodule. But then we just copy it and commit it back to the main app as submodules are nasty to deal with on production servers.
bin/wiki-update.shThe list of rooms your bot is going to join.
To start with create your own bot, a test room to enter and debug in. This needs to be changed so you would only join your own rooms, otherwise developers will get into a situation where everyone is joining the same rooms and the bots go crazy talking to each other!
This is where you add things that the bot can do. Some commands are broken into separate files such as cmds/thanks.js and cmds/update.js.
Each command gets a input which is a blob of data including what the user entered, and a bot instance.
The Knowledge base. This is an interface to all the data in the wiki.
This is for static messages that are fired based on regex matches. If you just want to add some basic responses, this is the place to edit.
Look at BotCommands, echo function. This is an example of a command being called. Anytime a user types a line starting with echo that will get passed to this function in input.
echo: function(input, bot) {
var username = input.message.model.fromUser.username;
return "@" + username + " said: " + input.message.model.text;
}The input object contains keyword and params fields. If you type echo this you'll get
//input
{
keyword: 'echo',
params: 'this'
}From any command you just return the new string you want to output. So you can add new commands with this knowledge.
In GBot.js
if (input.command) {
// this looks up a command and calls it
output = BotCommands[input.keyword](input, this);
} else {BotCommands is a list of functions. E.g.
BotCommands.thanks = function() { ... }where input.keyword is thanks then
BotCommands[input.keyword] is like saying BotCommands.thanks()
so then the params get also added in (input, this) so its
BotCommands[input.keyword](input, this);
//becomes
BotCommands.thanks(input, bot);All of the bot commands expect these two params. E.g. in thanks.js
var commands = {
thanks: function (input, bot) {In RoomMessages.js we also have a table of regex and matching functions.
{
regex: /\bth?a?n?[xk]s?q?\b/gim,
func: BotCommands.thanks
}We may switch all to just use this method in future. Would you like to help?
We use git submodules for some wiki data. to get these submodules you would do:
git submodule update --remote --checkout --init --recursiveHave a look at the HelpWanted label issues and consider making some first steps!
The labels, P1 = priority one, and 'S' means a small task, so good places to start.
