SYN-library
⭐ Getting started
This project uses node 20
Run npm ci
to set up the packages required.
Run npm run storybook
to view the UI libraries Storybook documentation.
🌀 Publishing to Chromatic
The storybook is published on Chromatic
This should be done as part of the chore task that updates the published version so that the published storybook matches the current npm package.
You can redeploy locally or in CI with npm run chromatic
.
ℹ The project token was added to the script via the --project-token flag. If you're running Chromatic via continuous integration, we recommend setting the CHROMATIC_PROJECT_TOKEN environment variable in your CI environment. You can then remove the --project-token from your package.json script.
We should perhaps do this!
🖼️ Icons
The library's icons predominantly come from Google's Material Symbols and Icons.
Adding a new icon
- Ensure the icon has been added to the SYN Library's Figma Icon's.
- On Figma, right click the icon you want to add. You should see a purple
20 x 20
bounding box appear around it. - Select
Copy as
>Copy as SVG
. - Create a file in the
src/icons
folder with your new icon name. It should follow the existing file name convention,[Name]Icon.tsx
. - A standard icon should receive at least one prop,
size
. Thisnumber
will dictate the height and width of the icon.
Use the following template to structure your icon:
import React from "react"
import { IconProps } from "./IconProps"
export const MyIcon = ({ size = 20 }: IconProps) => {
return (
<svg fill="none" height={size} viewBox="0 0 20 20" width={size} xmlns="http://www.w3.org/2000/svg">
{*/ <mask> */}
{*/ <g> */}
</svg>
)
}
- Your
<svg>
will likely have a<path>
tag within it, with thefill
attribute having a hardcoded hex value (likely to be#1E2428
). Change this tofill="currentColor"
. - Next, import your icon into
src/icons/Icons.stories.tsx
and add it to theICONS
array. Viewing the Icons story on Storybook should show all icons, including your new one. - Scroll to the bottom of the icon's Storybook page and change the
color
value using the colour wheel. Your icon should change colour. - Finally, export your new icon from the icon folders barrel file,
src/icons/index.ts
💻 Local Project Development
You can simultaneously develop this library alongside another local project.
- Navigate to the root directory of this UI library and run
npm link
. - Go to the root directory of your local project and run
npm link @synanetics/syn-library
. - Remember to run
npm run build
in the library if you make any changes, to ensure your project is using the latest version. Updates should be reflected in your local project immediately.
You will need to re-link the packages if you install other dependencies at any point during local development.
You want to unlink the local instance of the package via:
npm unlink --no-save @synanetics/syn-library
If you have made changes to the UI library and errors occur similar to the following:
SyntaxError: The requested module ABC does not provide an export named 'xyz'
Restarting WSL and VS Code will likely resolve this issue.
🧪 Testing
React Testing Library, Jest & Axe
Each component has a corresponding [Name].test.tsx
within it's folder.
React Testing Library is combined with jest-axe to run unit tests and prevent accessibility errors.
To manually run all tests, run npm run test:unit
.
Playwright
Playwright is used for integration tests.
Running Playwright tests
Run npm run test:integration
