## Building ngx-graph

To get started with development, clone a fork of the repository and run `yarn`.

## Development server

Run `yarn start` to serve Storybook at `http://localhost:6006/`. Storybook serves as the development and test environment for ngx-graph.

## Building

Run `yarn build:lib` to build ngx-graph.

## Running tests

Run `yarn test` to execute the linter.

## Release

- Checkout master (`git checkout master`)
- Pull master (`git pull`)
- Run tests (`yarn ci`)
- Examine log to determine next version (X.Y.Z)
- Run `git checkout -b release/X.Y.Z`
- Update version in `projects/swimlane/ngx-graph/package.json`.
- Update changelog in `CHANGELOG.md`
- Run `yarn package` to check the package format
