🧩 One design system, native to both React and Angular

We run a React app and an Angular admin panel at work. Same company, same brand, and on paper the same design. On screen it was a different story. The React button had a 6px radius; the Angular one had 4px. The focus rings were two slightly different blues. Nobody noticed until somebody did. And every time design changed a token, someone got to hand-port it into two codebases. Twice the work, and it still drifted. So I went looking for something that treated both frameworks as equals. The React kits don't speak Angular. The Angular ones don't share a look with anything on the React side. Nothing let me define the design once and have it show up, the same, in both. So I built bpdm/ui . One rule: the look lives in tokens I gave myself one hard rule: nothing about how a component looks is allowed to live inside the React or Angular code. Colour, spacing, radius, the easing on transitions, all of it sits in @bpdm/tokens as plain CSS variables, and both framework packages just read from there. The component owns structure, behaviour, and the accessibility plumbing. The look comes from the tokens. @import "tailwindcss" ; @import "@bpdm/tokens/tokens.css" ; Change one token and both frameworks move together. There's no "now go sync the Angular theme" step, because there's only one theme to sync. Four ship in the box (two light, two dark). Override the variables and you've re-skinned all of it. The same component, twice React: import { Button , Badge } from " @bpdm/ui " ; export function Example () { return ( < Button variant = "primary" > Get started < Badge appearance = "soft" > New </ Badge > </ Button > ); } Angular: import { Component } from " @angular/core " ; import { BpdmButton } from " @bpdm/ng " ; @ Component ({ selector : " app-root " , imports : [ BpdmButton ], template : `<button bpdmButton>Get started</button>` , }) export class App {} Same padding, same radius, same focus ring. The accessibility isn't literally shared code: Radix does that work on the React s
