Dev utils ​

Prod:

Attention!

This package is still in design phase. But you can use it during the development.

The @zurich/dev-utils NPM package is a package wit JavaScript (TypesCript) and SCSS code that can help to improve the whole DX (Development Experience) and QA (Quality Assurance) processes when su are using the Zurich Design System.

Install ​

The are two ways of installing the package:

Via CDN ​

Simply import the script in the <head> of your HTML:

html
<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="module" src="https://zds.zurich.com/0.5.22/@zurich/dev-utils/web-cli.js"></script>
  </head>
</html>

The available files are:

Local installation ​

You can also install it locally and get access to the SCSS and all the tools provided. We need to install the package:

bash
npm i -D @zurich/dev-utils

And then import the functionality in the context where is going to be used.

ts
import { isBoolean } from '@zurich/dev-utils/helpers'

Check each section to know about the imports.

Helpers ​

We offer a big collection of useful functions that can help developers. We do not recommend to use it via CDN because of performance issues, since you will be importing all the helpers.

You can import them from @zurich/dev-utils/helpers:

ts
import { isBoolean } from '@zurich/dev-utils/helpers'

DRY (Don't Repeat Yourself)

We provide some very useful functions with strong typing that might be really useful to complement the development process when you are using the Zurich Design System. We recommend to have a look to the available ones and get familiar with them, since they can save hours of development and they are already unit tested and documented from our side.

Check all the available helpers in here.

Type helpers ​

There's also a collection of type helpers that can be imported from @zurich/dev-utils/helpers:

ts
import type { Enumerate, KeysExcluding } from '@zurich/dev-utils/helpers'


type Result_1 = Enumerate<5>;    // type Result_1 = 0 | 1 | 2 | 3 | 4

type Example = {
  a: string;
  b: number;
  c: boolean;
};

type Result_2 = KeysExcluding<Example, string>;    // type Result_2 = 'b' | 'c'

Web CLI ​

Attention!

Do not use the Web CLI in production. This is only a tool for development and QA.

In order to use the Web CLI, we need to import it in the use context.

scss
@import '@zurich/dev-utils/web-cli';

It can be import via CDN too:

html
<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="module" src="https://zds.zurich.com/0.5.22/@zurich/dev-utils/web-cli.js"></script>
  </head>
</html>

Once the import is done, you would be able to access the Web CLI just by opening the dev tools of the browser and opening the console. Then just type ZDS. and the list of available commands will appear:
