Thank you for your interest in improving Celo SDK(s) and CLI(s).
If you want to contribute, but aren't sure where to start, you can create a new discussion.
There are multiple opportunities to contribute. It doesn't matter if you are just getting started or are an expert. We appreciate your interest in contributing.
IMPORTANT Please ask before starting work on any significant new features.
It's never a fun experience to have your pull request declined after investing time and effort into a new feature. To avoid this from happening, we invite contributors to create a new discussion to discuss API changes or significant new ideas.
This guide is intended to help you get started with contributing. By following these steps, you will understand the development process and workflow.
To start contributing to the project, clone it to your local machine using git:
$ git clone https://github.com/celo-org/developer-tooling.git
Navigate to the project's root directory:
$ cd developer-tooling
We use Node.js to run the project locally. You need to install the Node.js version specified in .nvmrc. To do so, run:
$ nvm install
$ nvm use
Once in the project's root directory, run the following command to install the project's dependencies:
$ yarn install
After installing the dependencies, the project is ready to be run.
The project is structured into multiple packages. Each package is located in the
packages/
directory. Each package has its own package.json
file and is
published independently.
For example:
- the
@celo/celocli
NPM package is located in thepackages/cli/
directory. - the
@celo/contractkit
NPM package is located in thepackages/sdk/contractkit/
directory.
Once you navigated to the package directory you want to run, inspect the package.json
file
and look for the scripts
section. It contains the list of available scripts that can be run.
When adding new features or fixing bugs, we'll need to bump the package versions. We use Changesets to do this.
INFO Only changes to the codebase that affect the public API or existing behavior (e.g. bugs) need changesets.
Each changeset defines which package(s) should be published and whether the change should be a major/minor/patch release, as well as providing release notes that will be added to the changelog upon release.
To create a new changeset, run:
$ yarn run changeset
This will run the Changesets CLI, prompting you for details about the change. You’ll be able to edit the file after it’s created — don’t worry about getting everything perfect up front.
Even though you can technically use any markdown formatting you like, headings should be avoided since each changeset will ultimately be nested within a bullet list. Instead, bold text should be used as section headings.
If your PR is making changes to an area that already has a changeset (e.g. there’s an existing changeset covering theme API changes but you’re making further changes to the same API), you should update the existing changeset in your PR rather than creating a new one.
Unfortunately, we don't have a consistent way of running the test suite across all packages yet. Some packages have their own test suites, while others don't have any tests at all. This is something we are working on improving.
When you open a Pull Request, the GitHub CI will run the available test suites for you, but you can also run them locally.
INFO Some tests are run automatically when you open a Pull Request, while others are run when a maintainer approves the Pull Request. This is for security reasons, as some tests require access to secrets.
✅ Now you're ready to contribute to Celo SDK(s) and CLI(s)!
