Usage

Step 1

Use exposeModule to expose module on window:

import { exposeModule } from '@xiaoman/o-modules'

function moduleFn() {
  return 'hello oModules'
}

exposeModule('HelloOModules', moduleFn)

use @xiaoman/webpack-plugin-module-manifest or @xiaoman/vite-plugin-module-manifest to generate module manifest, like:

{
  "CustomerActions": {
    "js": ["static/js/CustomerActions-b23edb27.js"],
    "css": [
      "static/css/entry-cb2eef2e.css",
      "static/css/api-9fb5ff20.css",
      "static/css/index.265f4a95.css",
      "static/css/deal-data-d7649152.css",
      "static/css/conf-c7843131.css",
      "static/css/index.04fd6d71.css"
    ]
  },
  "Dynamic": {
    "js": ["static/js/Dynamic-def41451.js"],
    "css": [
      "static/css/entry-cb2eef2e.css",
      "static/css/api-9fb5ff20.css",
      "static/css/index.265f4a95.css"
    ]
  },
  "Info": {
    "js": ["static/js/Info-169de637.js"],
    "css": [
      "static/css/entry-cb2eef2e.css",
      "static/css/api-9fb5ff20.css",
      "static/css/InfoField-cbffb9bc.css"
    ]
  },
  "Tags": {
    "js": ["static/js/Tags-8e020b71.js"],
    "css": [
      "static/css/entry-cb2eef2e.css",
      "static/css/api-9fb5ff20.css",
      "static/css/index.04fd6d71.css",
      "static/css/index.265f4a95.css"
    ]
  }
}

Step 2

Step 2-1

init oModules

// src/plugins/o-modules/valar.ts
import oModules from '@xiaoman/o-modules'

export async function useValarModules() {
  const options = {
    assetsRemote: 'https://127.0.0.1:5050/',
    manifestPath: 'https://127.0.0.1:5050/vite-assets.json',
    group: 'Valar' // stored all modules of the current remote server
  }

  return await oModules(options)
}

// NOTE: await top level support Chrome ≥ 89
// https://caniuse.com/mdn-javascript_operators_await_top_level
export const valarModules = await useValarModules()

// src/plugins/o-modules/tms.ts
import oModules from '@xiaoman/o-modules'

export async function useTmsModules() {
  const options = {
    assetsRemote: 'https://127.0.0.1:5055',
    manifestPath: 'https://127.0.0.1:5055/webpack-assets.json',
    group: 'TMS',
    // ineject js/css files
    inject: {
      js: ['https://cdn.jsdelivr.net/npm/antd@5.0.0/dist/antd.min.js'],
      css: ['https://cdn.jsdelivr.net/npm/antd@5.0.0/dist/reset.css']
    }
  }

  return await oModules(options)
}

// NOTE: await top level support Chrome ≥ 89
// https://caniuse.com/mdn-javascript_operators_await_top_level
export const tmsModules = await useTmsModules()

Step 2-2

maybe you need to prefetch some modules

import { useValarModules } from 'src/plugins/o-modules/valar.ts'
// import { valarModules } from 'src/plugins/o-modules/valar.ts'

const valarModules = await useValarModules()
valarModules.prefetchModules(['CustomerCard', 'CustomerList'])

import { useTmsModules } from 'src/plugins/o-modules/valar.ts'
// import { tmsModules } from 'src/plugins/o-modules/valar.ts'

const tmsModules = await useTmsModules()
tmsModules.prefetchModules(['TmsCard', 'TmsList'])

Step 3

use fetchModule to attach component or module

import { useValarModules } from 'src/plugins/o-modules/valar.ts'

const valarModules = await useValarModules()

// fetch on Demand
const dynamic = await valarModules.fetchModule('DynamicTab')
dynamic({
  container: '.remote-component-container',
  props: {
    companyInfo: props.companyInfo,
    isOwner: props.isOwner,
    companyId: props.companyInfo?.company_id
  },
  userInfo: userInfo?.value
})

Environment

All components supported in modern browsers, I try to ensure the support of neerly two or three versions.

I have limited energy and it's not start writing unit tests currently, if you encountered any bug, don't scold me and create a issue or PR.
