@leanjs/nuxt

Installation

If your NuxtJS app is in a monorepo (recommended) execute the following command at the root of your repository:

yarn add -W @leanjs/nuxt @leanjs/vue @leanjs/core

then, in the package.json of your NuxtJS app add the following

"peerDependencies": {
  "@leanjs/core": "*",
  "@leanjs/nuxt": "*",
  "@leanjs/vue": "*"
}

If your app is not in a monorepo, you can instead run:

yarn add @leanjs/nuxt @leanjs/vue @leanjs/core

Basic Usage

HostProvider

You have to add a HostProvider at the root of your nuxt component tree (in app.vue).

:::info HostProvider isn't exported from @leanjs/nuxt. You can lean more about HostProvider here :::

To add a HostProvider you must first create it by calling createRuntimeBindings. Read more about this in the @leanjs/vue package.

Example:

<template>
  <HostProvider :runtime="runtime">
    <NuxtPage />
  </HostProvider>
</template>

<script setup lang="ts">
  import { createRuntime, HostProvider } from "@my-org/vue-runtime";

  const runtime = createRuntime({
    context: { appName: "NuxtShell" }
  });
</script>

:::info Read @leanjs/core if you have not already created your own createRuntime function. :::

Host

The Host component "hosts" a composable app in a Nuxt host application.

Example:

<template>
  <Host
    :app="{ packageName: '@my-org/react-app-1' }"
  />
</template>

<script setup lang="ts">
  import { Host } from "@leanjs/nuxt";
</script>

The app prop

The app prop expects a GetComposableApp type.

Given a composable app created as follows:

import { createApp } from "@leanjs/vue-router";
import VueApp1 from "./VueApp1.vue";

// 👇 your app is created here
export default createApp(VueApp1, {
  appName: "VueApp1",
});

You can load this into a host application in 3 ways:

1. Standard esm import

<template>
  <Host
    :app="VueApp1"
  />
</template>

<script setup lang="ts">
  import { Host } from "@leanjs/nuxt";
  import VueApp1 from "@my-org/vue-app-1";
</script>

2. Dynamic import

<template>
  <Host
    :app="loadApp"
  />
</template>

<script setup lang="ts">
  import { Host } from "@leanjs/nuxt";
  const loadApp = () => import("@my-org/vue-app-1");
</script>

3. Runtime load

<template>
  <Host
    :app="{ packageName: "@my-org/vue-app-1" }"
  />
</template>

<script setup lang="ts">
  import { Host } from "@leanjs/nuxt";
</script>

The first two methods are examples of "build-time composition". They will be built as part of the host application bundle.

The 3rd method uses Webpack Module Federation to allow your application to be loaded at runtime.

:::caution In order to enable this feature, you must be using Webpack v5 :::

To set up your composable apps for runtime composition, you need to add a HostWebpackPlugin to your nuxt.config.js to enable this feature.

If this feature is enable, you need to build and deploy your composable apps independently. See @leanjs/aws to deploy your composable apps in AWS.

Limitations

Due to the nature of nuxt, we currently cannot support microfrontends that manage multiple routes in nuxt.

While we believe this is an unusual scenario, it is nonetheless a feature we'd like to add in the future.
