We welcome pull requests from Free Code Camp campers (our students) and seasoned JavaScript developers alike! Follow these steps to contribute:
-
Find an issue that needs assistance by searching for the Help Wanted tag.
-
Let us know you are working on it by posting a comment on the issue.
-
Feel free to ask for help in our Contributors Gitter room.
If you've found a bug that is not on the board, follow these steps.
-
Fork the project: How To Fork And Maintain a Local Instance of Free Code Camp
-
Create a branch specific to the issue or feature you are working on. Push your work to that branch. (Need help with branching?)
-
Name the branch something like
fix/xxx
orfeature/xxx
wherexxx
is a short description of the changes or feature you are attempting to add. For examplefix/email-login
would be a branch where I fix something specific to email login. -
Set up Linting to run as you make changes.
-
When you are ready to share your code, run the test suite
npm test
and ensure all tests pass. For Windows contributors, skip the jsonlint pretest run by usingnpm run test-challenges
, as jsonlint will always fail on Windows, given the wildcard parameters. -
Squash your Commits. Ref: rebasing
-
Submit a pull request from your branch to Free Code Camp's
staging
branch. Travis CI will then take your code and runnpm test
. Make sure this passes, then we'll do a quick code review and give you feedback, then iterate from there.
Prerequisite | Version |
---|---|
MongoDB | ~ ^3 |
Node.js | ~ ^6 |
npm (comes with Node) | ~ ^3 |
Updating to the latest releases is recommended.
Note: If this is your first time working with a node-gyp dependent module, please follow the node-gyp installation guide to ensure a working npm build.
The easiest way to get started is to clone the repository:
# Get the latest snapshot
git clone --depth=1 https://github.com/freecodecamp/freecodecamp.git freecodecamp
# Change directory
cd freecodecamp
# Install NPM dependencies
npm install
# Install Gulp globally
npm install -g gulp
# Install Bower globally
npm install -g bower
# Install Bower dependencies
bower install
Private Environment Variables (API Keys)
# Create a copy of the "sample.env" and name it as ".env".
# Populate it with the necessary API keys and secrets:
cp sample.env .env
Edit your .env
file and modify the API keys only for services that you will
use.
Note : Not all keys are required, to run the app locally, however MONGOHQ_URL
is the most important one. Unless you have MongoDB running in a setup different
than the defaults, the URL in the sample.env
should work fine.
You can leave the other keys as they are. Keep in mind if you want to use more
services you'll have to get your own API keys for those services and edit those
entries accordingly in the .env
file.
# Start the mongo server in a separate terminal
mongod
# Initialize Free Code Camp
# This will seed the database for the first time.
# This command should only be run once.
npm run only-once
# start the application
gulp
Now navigate to your browser and open http://localhost:3000. If the app loads, congratulations – you're all set. Otherwise, let us know by opening a GitHub issue and with your error.
You should have ESLint running in your editor, and it will highlight anything doesn't conform to Free Code Camp's JavaScript Style Guide (you can find a summary of those rules here. Please do not ignore any linting errors, as they are meant to help you and to ensure a clean and simple code base. Make sure none of your JavaScript is longer than 80 characters per line. The reason we enforce this is because one of our dependent NPM modules, jsonlint, does not fully support wildcard paths in Windows.
Do not file an issue until you have followed these steps:
-
Read Help I've Found a Bug wiki page and follow the instructions there.
-
Asked for confirmation in the appropriate Help Room
-
Please do not open an issue without a 3rd party confirmation of your problem.
A pull request (PR) is a method of submitting proposed changes to the Free Code Camp Repo (or any Repo, for that matter). You will make changes to copies of the files which make up Free Code Camp in a personal fork, then apply to have them accepted by Free Code Camp proper.
Free Code Camp Issue Mods and staff are on hand to assist with Pull Request related issues on our Contributors Chat Room.
The best way to find out any code you wish to change/add or remove is using the GitHub search bar at the top of the repository page. For example, you could search for a challenge name and the results will display all the files along with line numbers. Then you can proceed to the files and verify this is the area that you were looking forward to edit. Always feel free to reach out to the chat room when you are not certain of any thing specific in the code.
Take away only one thing from this document, it should be this: Never, EVER
make edits to the staging
branch. ALWAYS make a new branch BEFORE you edit
files. This is critical, because if your PR is not accepted, your copy of
staging will be forever sullied and the only way to fix it is to delete your
fork and re-fork.
There are two methods of creating a pull request for Free Code Camp:
- Editing files via the GitHub Interface
- Editing files on a local clone
This is the recommended method. Read about How to Setup and Maintain a Local Instance of Free Code Camp.
- Perform the maintenance step of rebasing
staging
. - Ensure you are on the
staging
branch usinggit status
:
$ git status
On branch staging
Your branch is up-to-date with 'origin/staging'.
nothing to commit, working directory clean
-
If you are not on staging or your working directory is not clean, resolve any outstanding files/commits and checkout staging
git checkout staging
-
Create a branch off of
staging
with git:git checkout -B branch/name-here
Note: Branch naming is important. Use a name likefix/short-fix-description
orfeature/short-feature-description
. Review the Contribution Guidelines for more detail. -
Edit your file(s) locally with the editor of your choice
-
Check your
git status
to see unstaged files. -
Add your edited files:
git add path/to/filename.ext
You can also do:git add .
to add all unstaged files. Take care, though, because you can accidentally add files you don't want added. Review yourgit status
first. -
Commit your edits:
git commit -m "Brief Description of Commit"
-
Squash your commits, if there are more than one.
-
Push your commits to your GitHub Fork:
git push -u origin branch/name-here
-
Go to Common Steps
Note: Editing via the GitHub Interface is not recommended, since it is not possible to update your fork via GitHub's interface without deleting and recreating your fork.
Read the Wiki article for further information
-
Once the edits have been committed, you will be prompted to create a pull request on your fork's GitHub Page.
-
By default, all pull requests should be against the FCC main repo,
staging
branch. -
Submit a pull request from your branch to Free Code Camp's
staging
branch. -
The title (also called the subject) of your PR should be descriptive of your changes and succinctly indicates what is being fixed.
-
Do not add the issue number in the PR title.
-
Examples:
Add Test Cases to Bonfire Drop It
Correct typo in Waypoint Size Your Images
-
-
In the body of your PR include a more detailed summary of the changes you made and why.
- If the PR is meant to fix an existing bug/issue, then, at the end of
your PR's description, append the keyword
closes
and #xxxx (where xxxx is the issue number). Example:closes #1337
. This tells GitHub to close the existing issue, if the PR is merged.
- If the PR is meant to fix an existing bug/issue, then, at the end of
your PR's description, append the keyword
-
Indicate if you have tested on a local copy of the site or not.
Once your PR is accepted, you may delete the branch you created to submit it. This keeps your working fork clean.
You can do this with a press of a button on the GitHub PR interface. You can
delete the local copy of the branch with: git branch -D branch/to-delete-name
Don't despair! You should receive solid feedback from the Issue Moderators as to why it was rejected and what changes are needed.
Many Pull Requests, especially first Pull Requests, require correction or updating. If you have used the GitHub interface to create your PR, you will need to close your PR, create a new branch, and re-submit.
If you have a local copy of the repo, you can make the requested changes and
amend your commit with: git commit --amend
This will update your existing
commit. When you push it to your fork you will need to do a force push to
overwrite your old commit: git push --force
Be sure to post in the PR conversation that you have made the requested changes.
