For using individual components in an app, refer to the individual component's README.


Components ready for use:

Components still in development:


  1. Fork project to your repository
  2. Clone to the local machine with git clone
  3. cd into the directory
  4. Run npm install
  5. Ensure the IBM Plex Sans is imported with <link href=",400,500,500i,700" rel="stylesheet"> is in the *.html file of your main app
  6. Build a production state with npm run build
  7. Transpile code for build with npm run transpile
  8. Create a global link with npm link
  9. In your main app directory, run npm link @accordproject/cicero-ui

Available Scripts

In the project directory, you can run:

npm run start

Runs the app in the development mode.
Open http://localhost:8080 to view it in the browser.

The page will reload if you make edits.
You will also see any lint errors in the console. NOTE: These require templates to be passed down through props from an app in which these components should be rendered.

npm run test

Launches JEST over the repository. Current snapshot tests require npm test -- -u to update when all changes are final.

npm run lint

Runs ESLint.

npm run build

Builds the app for production to the demo folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
