Workflows

​

Development

To work on OnchainKit components with live UI feedback:

pnpm f:play dev

This will build the OnchainKit package in watch mode, and start a development environment (the playground) where you can see your components in action.

As you make changes, the playground will update automatically.

Navigate to http://localhost:3000 to open the playground.

​

Building

To build the package:

pnpm f:ock build

​

Testing

Write and update existing unit tests. You can run tests with:

pnpm f:ock test

For watching file changes and rerunning tests automatically:

pnpm f:ock test:watch

We expect 100% code coverage for any updates. You can get coverage information with:

pnpm f:ock test:coverage

If the coverage drops below 100%, look at the coverage report generated by the above command with:

open coverage/index.html

​

Updating changelog

To update the change log, run:

pnpm changeset

Select minor and use the following format for the summary:

- **feat**: feature update information. By @your-github-id #XX (XX is the PR number)

Possible values are:

• feat
• fix
• docs
• chore

​

Feature request

Have a component in mind that we are not supporting yet? You can submit a feature request to our Github. Create a “New issue” and label it “Feature Request: …”.
