# @vue/cli-ui ### Local development Before starting a local cli-ui instance, consider following the [contributing guide](https://github.com/vuejs/vue-cli/blob/dev/.github/CONTRIBUTING.md) in order to download all required dependencies of vue-cli's packages. Just after, you should build once then serve `@vue/cli-ui-addon-webpack` by running: ```bash cd ../cli-ui-addon-webpack yarn build # just do once yarn serve ``` Then you start the ui server (based on Apollo): ``` cd ../cli-ui yarn run apollo ``` And then in another terminal, you should serve the ui web app: ``` yarn run serve ``` #### Testing For running E2E tests, you just need to run: ``` yarn run test:e2e ``` This will open a new [Cypress](https://www.cypress.io/) window. You can now run all or specific integration tests.
