Moonbeam primarily uses GitHub Pull Requests to coordinate code changes. If you wish to propose a contribution, open a pull request and review the template, which explains how to document your proposal.
You may also consider joining our Discord server or Element room to discuss your changes.
You can explore our crate-level documentation.
This documentation is
automatically built and reflects the latest master commit.
Moonbeam is following the Substrate code style.
In addition, we incorporate several tools to improve code quality. These are integrated into our CI and are expected to pass before a PR is considered mergeable. They can also be run locally.
- clippy - run with
cargo clippy --release --workspace - rustfmt - run with
cargo fmt -- --check - editorconfig - integrate into your text editor / IDE
- prettier - run with
npx prettier --check --ignore-path .gitignore '**/*.(yml|js|ts|json)'(runs againsttypescriptcode)
