Parcels Overview Overview

At its core, parcels overview is about doing one thing well inside your single-spa project. Once you understand the pattern, you can apply it consistently across features and teams.

Good parcels overview pays off across the whole codebase: fewer surprises, easier testing, and smoother onboarding. The snippet below is a solid starting point.

import Parcel from 'single-spa-react/parcel';

<Parcel
  config={() => System.import('@org/product-card')}
  wrapWith="div"
  productId={id}
/>

Parcels let one framework render a component owned by another, independent of routing.

How Parcels Overview Works in Single-SPA

Parcels Overview is part of how single-spa lets multiple applications — even in different frameworks — coexist on one page. A root config registers each app and controls when it is active.

Parcels let one framework render a component owned by another, independent of routing.

• A root config registers apps and calls start().
• Each app exports bootstrap, mount, and unmount lifecycles.
• activeWhen decides which routes each app owns.
• Import maps resolve each app's bundle at runtime.

Practical Guidance for Parcels Overview

For reliable micro frontends, parcels overview should isolate failures and keep shared state minimal. Let each team own its app end to end while agreeing on a few shared contracts.
