Handset 📞

Handset is a library of Vue components for Dialtone. The goal is to simplify and standardize the use of common UI patterns and behaviour across all Dialpad projects.

Project Status

Handset is a new project, and as such it is under constant development as we add new components and refine existing ones. Please refer to the project board to see the status of Handset components and request new components that should be in the Handset library.

Timeline

Our goal is to have a stable 1.0 release in early 2021. At this point, we will split Handset into a separate repository and follow semantic versioning.

Usage

Handset components can be imported directly from the package. Some components also export named constants, which can be imported as well:

import { HsInput, VALIDATION_MESSAGE_TYPES } from '@dialpad/handset';

Storybook Component Documentation

Handset uses Storybook for documentation of components, as well as an environment for local development. Please see the Storybook Documentation Site for specific usage information and interactive documentation for each Handset component.

All components in Handset should have stories written for them in Storybook. For more information on how to write stories, see the documentation.

Running Storybook Locally

Storybook provides a sandbox to develop and experiment with components locally, in isolation from the rest of the app. With Storybook you get live reloading of component templates and styles, just like you would in the app. You can also test different props and slots and see the effects in real time, test accessibility issues, and more.

To run Storybook locally, first install the dependencies:

npm run install:storybook

Then you can run the dev server:

npm run storybook

Developing Handset Components

Building components for Handset is similar to components for Dialpad or UberConference, but there are some differences. Remember that Handset is a shared library so more care has to be taken to avoid breaking changes.

Remember that Handset is a separate project, so be sure to run the lint and unit tests for Handset separately whenever making changes to the library.

See CONTRIBUTING.

CSS & Dialtone

Dialtone components should utilize the global immutable CSS classes provided by Dialtone whenever possible. It is a requirement of any project using Handset to include these classes.

If needed, you can also write custom CSS using the Dialtone LESS variables or mixins by importing ../css/dialtone.less.

Please do not use any scoped CSS in Handset components.

Unit Tests

Each component should have a corresponding unit test in the tests/specs directory. There is no special test setup as Handset components do not have access to the Vuex store or custom methods/directives.

Exports

When adding a new component, please add its exports to index.js, including any named exports, so they're available for import to users of Handset:

export {
  default as HsInput,
  INPUT_SIZE_TYPES,
} from './components/input.vue';

External Dependencies

Handset components are designed to be used in a variety of different projects. As such, Handset components should be pure Vue components with no dependencies on global Vue plugins or stores, except when noted below. This in particular means:

• No access to the Vuex store. Different projects will have different store structures, and so Handset components cannot access the Vuex store. Handset components should take data as props only.
• No I18n. Each project will have its own i18n implementation. Any text needed in a Handset component should be passed as props or slots.
• No custom directives. Directives in Vue are installed globally and vary from project to project. Custom directives (such as v-tooltip) cannot be used in Handset components.
• No other custom global methods. Some projects may implement custom global methods on the Vue object. Handset components are limited to the built-in Vue methods.
• No imports outside of the handset directory.
• Vue 2 compatibility. Handset components should ideally support Vue 2 and 3, but a minimum of Vue 2 support is currently required.

Using Handset in your Project

Project using Handset should be aware of the requirements:

• Dialtone classes must be made available globally (to avoid duplication, Handset does not do this for you).
• A tool like Webpack must be used to package the SFC components from Handset.
• LESS preprocessor support for Vue SFC <style> blocks.
• Handset components are built for Vue 2, with Vue 3 support coming soon.

These requirements are enforced via peerdependencies of Handset when possible.
