## What
Front components run in a Web Worker with the remote-dom polyfill, which
installs a fake `window`. Native `error` and `unhandledrejection` events
only fire on the real worker scope, so a component's `window.onerror`,
`window.addEventListener('error', ...)`, or
`window.onunhandledrejection` handler is a **silent no-op** today —
error-tracking libraries (Sentry-style) never see anything.
This adds `installErrorEventBridge` to the worker bootstrap: it listens
for the native `error`/`unhandledrejection` events and re-dispatches
equivalent events onto the fake `window`, so component-registered
handlers fire as they would on the web. It is guarded to no-op outside
the worker (when the fake window is the global scope) and swallows
errors thrown by a component's own handler.
## Scope
Worker-side only, no host, SDK, or RPC changes. Uncaught synchronous
errors already reach the host error panel via the native worker
`onerror`; surfacing unhandled promise rejections to the host panel is a
separate follow-up.

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
