Dialtone

The monorepo for Dialpad's design system Dialtone.

All separate packages of dialtone are also deployed individually. If you would like to use an individual package rather than the combined Dialtone package, you can find documentation for each package in the following table.

Usage

The below usage instructions are for the combined package.

Install it via NPM:

Using Vue@3

npm install @dialpad/dialtone @dialpad/i18n

Using Vue@2

npm install @dialpad/dialtone @dialpad/i18n-vue2

### Import packages:

#### Without theming

If you don't care about theming and just want to use Dialtone with the default light theme:

- CSS

```css
@import "@dialpad/dialtone/css-default-theme";

• JavaScript

import "@dialpad/dialtone/css-default-theme";

With theming

If you want to use theming, import from the below path. This file does not include design tokens so it is required to also set a theme to apply design tokens to the root element.

• CSS

@import "@dialpad/dialtone/css";

• JavaScript

import "@dialpad/dialtone/css";

Set theme via setTheme() JavaScript function (preferred)

Import the theme you want to use and set it via the setTheme function:

import { setTheme } from '@dialpad/dialtone/themes/config';
import DpLight from '@dialpad/dialtone/themes/dp-light';
setTheme(DpLight);

Possible themes are as follows:

• DpLight - Dialpad Light
• DpDark - Dialpad Dark
• TmoLight - T-Mobile Light
• TmoDark - T-Mobile Dark
• ExpressiveLight - Marketing Light
• ExpressiveDark - Marketing Dark
• ExpressiveSmLight - Marketing Small Light
• ExpressiveSmDark - Marketing Small Dark

There is an optional second parameter to setTheme that allows you to set the theme on a specific element. This is useful in the case of a shadow DOM when you want to apply the theme to the root element of the shadow DOM rather than the document root. If you do not set this parameter the theme will be applied to the document root.

import { setTheme } from '@dialpad/dialtone/themes/config';
import DpLight from '@dialpad/dialtone/themes/dp-light';
setTheme(DpLight, document.querySelector('#my-shadow-root-host'));

Set theme manually by importing files

You may want to use this method if you are unable to use JavaScript.

You need to import two tokens files in order to apply a theme. A base tokens files, which is either light or dark, and a semantic brand tokens file which is named after a brand and theme 'tokens-dp-light', 'tokens-dp-dark', 'tokens-tmo-light', ...

• CSS

@import "@dialpad/dialtone/tokens/tokens-base-light.css" // Base light theme
@import "@dialpad/dialtone/tokens/tokens-dp-light.css" // Dialpad light brand

• JavaScript

import "@dialpad/dialtone/tokens/tokens-base-light.css" // Base light theme
import "@dialpad/dialtone/tokens/tokens-dp-light.css" // Dialpad light brand

Dialtone icons

• Vue 2:

// Named import
import { DtIconArrowUp } from '@dialpad/dialtone-icons/vue2';
import { DtIllustrationBlankSpace } from '@dialpad/dialtone-icons/vue2';

// Default import (Preferred if using webpack as it is tree-shakeable by default)
import DtIconArrowUp from '@dialpad/dialtone-icons/vue2/arrow-up';
import DtIllustrationBlankSpace from '@dialpad/dialtone-icons/vue2/blank-space';

• Vue 3:

// Named import
import { DtIconArrowUp } from '@dialpad/dialtone-icons/vue3';
import { DtIllustrationBlankSpace } from '@dialpad/dialtone-icons/vue3';

// Default import (Preferred if using webpack as it is tree-shakeable by default)
import DtIconArrowUp from '@dialpad/dialtone-icons/vue3/arrow-up';
import DtIllustrationBlankSpace from '@dialpad/dialtone-icons/vue3/blank-space';

Dialtone Vue components

• Vue 2

// Named import
import { DtButton } from "@dialpad/dialtone/vue2"

// Default import (Preferred if using webpack as it is tree-shakeable by default)
import { DtButton } from "@dialpad/dialtone/vue2/lib/button"

• Vue 3

// Named import
import { DtButton } from "@dialpad/dialtone/vue3"

// Default import (Preferred if using webpack as it is tree-shakeable by default)
import { DtButton } from "@dialpad/dialtone/vue3/lib/button"

Dialtone mono-package

Dialtone is a mono-package that includes many packages within it to ease the maintenance of versions of the library.

How our bundling works

To achieve this we needed to create certain configs through the monorepo to be able to handle them even if they have the same package name e.g: @dialpad/dialtone-vue.

1. In root package.json:
   • pnpm:
     • peerDependencyRules include vue": "^2.6 || ^3.2" to make sure we don't have warnings related to vue version mismatch.
     • packageExtensions tells pnpm which Vue version to use for each package.
   • dependencies doesn't include any specific Vue 2 or Vue 3 dependencies as this causes issues on the client when trying to use exports from ./vue2 or ./vue3.
2. On individual packages package.json files:
   • Include the specific dependencies in case someone uses the individual package
   • In vite.config.jsVue 2, Vue 3 add dependencies to external to make sure they don't cause issues on product. (This is more specific for the Vue 2 package, as product is depending on Vue 2.6 and any dependency that needs a newer Vue version will cause issues).
3. In project.json
   • Include implicit dependencies to make sure NX builds them before trying to copy the files to the mono-package.
4. In gulpfile.cjs
   • Copy the built files into the root dist folder.

Included packages

• Dialtone CSS
• Dialtone Tokens
• Dialtone Vue 2
• Dialtone Vue 3

Tree-shaking

Tree-shaking is a feature that allows you to remove unused code from your bundle, and it is enabled by default in our build process for Dialtone, Dialtone Vue, Dialtone Combinator and Dialtone Icons.

We achieve tree-shaking primarily via three mechanisms across the packages:

Marking packages as side effect free

sideEffects: false is set so bundlers can drop unused imports.

• @dialpad/dialtone → package.json line 242
• @dialpad/dialtone-vue (vue2) → package.json line 145
• @dialpad/dialtone-vue (vue3) → package.json line 145
• @dialpad/dialtone-combinator → package.json line 56
• @dialpad/dialtone-icons → package.json line 98

Publishing ESM builds (with dual ESM/CJS via exports map)

Packages expose ESM for bundlers to statically analyze and tree-shake, with CJS fallbacks.

• @dialpad/dialtone-vue (vue3):
  • "type": "module",
  • "module": "./dist/dialtone-vue.js",
  • "main": "./dist/dialtone-vue.cjs",

Deep, per-module entry points to enable fine-grained import paths

Exports maps expose subpath entries so consumers can import only what they need (which aids tree-shaking and avoids pulling entire bundles):

• @dialpad/dialtone exposes ./vue3/lib/* and ./vue2/lib/* map to individual component imports.
• @dialpad/dialtone-vue exposes ./lib/* for individual component imports.
• @dialpad/dialtone-icons exposes ./vue3/* and ./vue2/* for individual icon/illustration imports.

Please read our contributing guide before submitting a pull request.

Quick start

If you would like to contribute to Dialtone without having to do any local environment setup, you can use GitHub Codespaces. You can initialize a new Codespace by clicking the green "Code" button at the top right of the Dialtone GitHub page.

Please see the Codespaces docs for more information.

Local development

PNPM

PNPM (Performant NPM) is a package management solution designed to address the challenges posed by traditional package managers.

We use PNPM to manage everything related to NPM, adding, installing, removing and publishing packages.

You will need to install PNPM locally to contribute to this project. https://pnpm.io/installation

Installation

npm install -g pnpm

Do

Use PNPM to manage package dependencies

pnpm add eslint --filter dialtone-icons

Don't

Run package scripts with PNPM, this will not use NX cache and pipelines, so you might end up missing dependencies that needed to be built before.

pnpm run --filter dialtone-css build

NX

Nx is a build system with built-in tooling and advanced CI capabilities. It helps you maintain and scale monorepos, both locally and on CI.

NX manages the scheduling and caching of our PNPM scripts.

We still rely on the package installation and package linking mechanism that PNPM workspaces provide us, but use Nx instead to run our tasks in the most efficient way.

One of the main benefits of adding Nx to our PNPM workspace is speed via caching.

Running commands via NX will enable us to do several things:

• Set up the project dependencies to other projects command, if they need to run before a specific command.
• Improve the speed of the command execution by saving its output to cache.
• Run the command on the affected projects only.

⚠️ You can run the commands with PNPM too, but it's not advisable as you'll lose the advantages that NX provides.

For more information, check setup a monorepo with PNPM workspaces and NX

Installation

It is recommended to install NX globally via:

pnpm add --global nx@latest

Do

Use NX to run scripts, this will use cache, improve the performance, and build any dependency needed before running your command.

nx run dialtone-css:build

Don't

Try installing packages with NX, this doesn't work at all, please use PNPM instead.

nx add eslint --filter dialtone-icons

Running the projects

First, install the dependencies for all the monorepo packages and apps.

pnpm install

Dialtone documentation site

nx run dialtone-documentation:start

This will start the documentation site and watch the library for changes, it will be live updated with any changes.

Access the local server at http://localhost:4000

Dialtone Vue 2 storybook

nx run dialtone-vue2:start

Access the local storybook server for Dialtone Vue 2 via http://localhost:9010/

Dialtone Vue 3 storybook

nx run dialtone-vue3:start

Access the local storybook server for Dialtone Vue 3 via http://localhost:9011/

Common Commands

Production build the root project

nx run dialtone:build

Use the --filter flag to run commands for a specific package or app.

Adding dependencies for individual packages

pnpm add <dependency> --filter <package or app name>

Example:

pnpm add eslint --filter dialtone-icons

To install a local dependency, just add the --workspace flag

pnpm add <dependency> --filter <package or app name> --workspace

Example:

pnpm add @dialpad/dialtone-tokens --filter dialtone-icons --workspace

Running commands for individual packages

You can run commands like build, test, start for individual packages from the root of the project using:

nx run <package/app>:<target>

Example:

nx run dialtone-documentation:build

Clean build artifacts and cache

Use this to clear stale build artifacts and reset the build cache. Common scenarios include switching branches, troubleshooting unexpected build behavior, or recovering from interrupted builds. This is rarely needed because build scripts already clean their own dist folders and Nx cache invalidation handles most staleness automatically.

# Clean everything (dist folders and Nx cache)
pnpm clean

# Clean only dist folders (stale build artifacts)
pnpm clean:dist

# Clean only Nx cache (confused incremental builds)
pnpm clean:cache

What gets cleaned:

• clean:dist removes packages/dialtone-tokens/dist and VuePress cache/temp directories
• clean:cache clears Nx's build cache (.nx/cache)
• clean runs both in sequence

Use local package in another project

A way to see local Dialtone changes in a local running frontend is to use a local package.

To create a Dialtone package, first run (in Dialtone repo):

pnpm pack

This will generate a .tgz file, with the same format as the one published on npm. To use this package on another project you can run:

npm install <path to previously generated tgz file>
npm run dev

Releasing

Currently, Dialtone packages are being released in two different ways: scheduled and manually. The scheduled release will only release changes to production while manually you can choose to release alpha or beta branches.

Production

Scheduled

On every Tuesday at 10:00 am UTC, release action will trigger the production release process which automatically release all packages that need to be released following the next steps:

1. Run the release target on every project.
2. Merge the release commits created by the semantic release bot on staging to production branch.
3. Push the production branch.
4. The publish action will publish the packages with its corresponding tag.

Manually

In case you need to release earlier than the next scheduled date, you can trigger the release via Run workflow on GitHub.

1. Select staging branch.
2. Select the package that you want to release or leave it empty to release all of them.

This will trigger the release action, release changes on staging and automatically publish the selected packages following the next steps:

1. Run the release target on selected packages (all if package is empty).
2. Merge the release commits created by the semantic release bot on staging to production branch.
3. Push the production branch.
4. The publish action will publish the packages with its corresponding tag.

Alpha/Beta

1. Merge your changes to the branch you want to release, commit and push to origin. (Note: If your dialtone version number is behind the last production release number, it may fail. Merge in staging or update the version number manually.)
2. Go to GitHub and click on Run workflow.
3. Select alpha or beta branch.
4. Select the package that you want to release or leave it empty to release all of them.

This will trigger the release action, release changes on the selected branch and automatically publish the selected packages following the next steps:

1. Run the release target on selected packages (all if package is empty).
2. The publish action will publish the packages with its corresponding tag.

Testing

Run Vue unit tests

nx run dialtone:test:vue

Run Vue 2 tests

nx run dialtone-vue2:test

Run Vue 3 tests

nx run dialtone-vue3:test

Run Vue 2 unit tests with coverage

nx run dialtone-vue2:test:coverage

Run Vue 3 unit tests with coverage

nx run dialtone-vue3:test:coverage

These will generate a JSON and HTML report in the coverage directory.

Test Coverage thresholds

The coverage thresholds are defined in the vitest.config.ts file. When submitting a PR the CI will run the tests with coverage and fail if the coverage is below the thresholds.
