Development

Setup

To set up this project you'll need git and yarn installed. Note that Yarn v4 is required to install the dependencies and build the project.

From your command line:

# Enable Yarn v4
corepack enable
yarn set version stable

# Clone this repository
$ git clone https://github.com/graphprotocol/contracts

# Go into the repository
$ cd contracts

# Install dependencies
$ yarn

# Build projects
$ yarn build

Versioning a package

To version a package, run the following command from the root of the repository:

# Change directory to the package you want to version
$ cd packages/<package-name>

# Bump the version
$ yarn version <major|minor|patch>

Note on cross referenced packages: Bumping the version of a package that is cross referenced by another package will automatically bump the dependency version in the other package. For example, if you bump the version of sdk from 0.0.1 to 0.0.2, the required version of sdk in the contracts package will automatically be bumped to 0.0.2. Depending on the nature of the change you might need to bump (and publish) a new version of the contracts package as well.

Publishing a package

Packages are published and distributed via NPM. To publish a package, run the following command from the root of the repository:

# Publish the package
$ yarn npm publish --access public --tag <tag>
