Vue State Management

Vue State Management Overview

Vue State Management is a building block you will reach for often in single-spa. It keeps related logic together and makes your intent obvious to reviewers and future maintainers.

When you learn vue state management properly, you avoid the guesswork that leads to bugs and rework. The example below shows the shape you will use in most real single-spa projects.

import { h, createApp } from 'vue';
import singleSpaVue from 'single-spa-vue';
import App from './App.vue';

const vueLifecycles = singleSpaVue({
  createApp,
  appOptions: { render: () => h(App) },
});

export const { bootstrap, mount, unmount } = vueLifecycles;

single-spa-vue turns a Vue app into mountable single-spa lifecycles.

Vue State Management Example

registerApplication({
  name: '@org/app',
  app: () => System.import('@org/app'),
  activeWhen: ['/app'],
});
start();

• Start from a minimal Vue State Management example and grow it only as needed.
• Keep configuration explicit so Vue State Management behaves the same in every environment.
• Name things clearly so teammates understand your Vue State Management at a glance.
• Add tests around Vue State Management early to lock in expected behaviour.

How Vue State Management Works in Single-SPA

Vue State Management 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.

single-spa-vue turns a Vue app into mountable single-spa lifecycles.

• 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 Vue State Management

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

Common Mistakes

• Skipping error handling and edge cases when wiring up vue state management.
• Leaving vue state management untested, so regressions slip into production.
• Over-engineering vue state management before you actually need the extra flexibility.
• Ignoring documentation, which makes vue state management hard for the next developer to change.

Key Takeaways

• Vue State Management is a core part of working effectively with single-spa.
• Start small and keep vue state management focused on a single responsibility.
• Apply consistent patterns so vue state management scales across your project.
• Test and document vue state management to keep it maintainable over time.
