Lens — the design system for Loom products

Installation

Add Lens to your app:

yarn add @loomhq/lens

Add dependencies:

yarn add @emotion/core
yarn add @emotion/styled

Install CSS variables

getThemeStylesString() and getAllCssVarsString() return strings that contain all CSS variables. Use these functions and inject the output to a style tag in the head:

import { getThemeStylesString, getAllCssVarsString } from '@loomhq/lens'

const style = document.createElement('style');
style.innerHTML = getThemeStylesString() + getAllCssVarsString();
document.head.appendChild(style);

In some cases you might need to inject the CSS variables to a specific element. Pass a string argument to getThemeStylesString() and getAllCssVarsString():

getThemeStylesString('.myGlobalElement')
getAllCssVarsString('.myGlobalElement')

Install CSS utilities

CSS classes are exported as a string and can be injected to a style tag in the head:

import { cssUtilities } from '@loomhq/lens'

const style = document.createElement('style');
style.innerHTML = cssUtilities();
document.head.appendChild(style);

Upgrading Lens versions

loom

From the root of the main Loom repo

1. Move into the webapp-client directory.

cd projects/webapp-client

1. Upgrade the Lens package with pnpm (you can ignore the warnings).

pnpm up -r @loomhq/lens --latest

This tells pnpm to find all packages in the workspace that use lens, and upgrade them all to the latest version

1. From the root, fix dependencies and upgrade Lens globally

cd ... && pnpm deps:fix && pnpm i

This shouldn't be necessary, but will correct any blocking issues.

Issue: If you're still having issues accessing new imports or code features from Lens after the above commands, make clean-node-deps in root of the repo and then reinstall everything with pnpm i.

1. Run changesets so that it generates the necessary .md file for release.

All dependents of these packages that will be incompatible with the new version will be patch bumped when this changeset is applied.

🦋  Is this your desired changeset? (Y/n) › [type Y]

1. A new randomly-named .md file should be generated into the changesets directory. Commit this file to your changes.

2. For any changes to existing components, do your due diligence and check the component changes locally within the repo.

Add an icon to the icon set

Once you have the SVG of the new icon to be added, make sure all strokes are outlined. Set <svg> attributes to viewBox="0 0 24 24" fill="none" {...props} and <path> attributes to fill="currentColor".
