Installation

npm install vue-easy-renderer -S

Peer Dependency

npm i vue vuex vue-router vue-loader vue-server-renderer -S

Example

Vue File

Create the vue file in component/hello_word/hello_word.vue

<template>
  <div>hello {{world}}</div>
</template>
<style scoped>
</style>
<script>
  export default {
    name: 'HelloWorld',
    data() {
      return {
        world: ''
      };
    }
  }
</script>

Koa.js 2

'use strict';

const path = require('path');
const Koa = require('koa');
const serve = require('koa-static');
const vueEasyRenderer = require('vue-easy-renderer').koaRenderer;

const renderer = vueEasyRenderer(path.resolve(__dirname, './component'));
const app = new Koa();

app.use(serve('./dist'));
app.use(renderer);

// with ES7 async/await
// app.use(async ctx => {
//   await ctx.vueRender('simple.vue', {hello: 'world!'});
// });

app.use(ctx => ctx.vueRender('hello_world/hello_world.vue', {world: 'world!'}));

app.listen(8080);

console.log('vue-easy-renderer koa example start in 127.0.0.1:8080');
module.exports = app;

Express.js

'use strict';

const path = require('path');
const express = require('express');
const vueEasyRenderer = require('vue-easy-renderer').connectRenderer;

const renderer = vueEasyRenderer(path.resolve(__dirname, './component'));
const app = express();

app.use(express.static('./dist'));
app.use(renderer);

app.get('/', (req, res) => res.vueRender('hello_world/hello_world.vue', {world: 'world!'}));

app.listen(8081);

console.log('vue-easy-renderer express example start in 127.0.0.1:8081');
module.exports = app;

Result

The browser get the html:

<html>
<head>
 <script>window.__VUE_INITIAL_STATE__ = {"world":"world!"};</script>
</head>
<body>
  <div server-rendered="true" data-v-30ca8d89>hello world!</div>
</body>
</html>

Detail in Full example

API

vueRender(path,data,config)

Use ctx.vueRender() in koa.js or res.vueRender() in express

Param	Type	Description
path	`String`	`*.vue` file path base on `Options.basePath`
data	`Object`	render data, will be merged into vue instance `data`
[config]	`Object`	renderer config
[config.pure]	`Boolean`	default `false`, `pure:true` will render `*.vue` file without head and tail

Renderer Options

vueEasyRenderer(basePath,options)

With Koa.js 2

const vueEasyRenderer = require('vue-easy-renderer').koaRenderer;
const renderer = vueEasyRenderer(bastPath, options);

With Express.js

const vueEasyRenderer = require('vue-easy-renderer').connectRenderer;
const renderer = vueEasyRenderer(bastPath, options);

Options

Param	Type	Description
basePath	`string`	`*.vue` file base path
[options]	`Object`	renderer options
[options.plugins]	`Array<Object\|string>`	vue plugins, e.g. `[vueRouter]`, it also support using plugin path string, e.g. `[path.resolve('../app/resource.js')]`
[options.preCompile]	`Array`	pre-compile `*.vue` file list
[options.head]	`Object`	common html head config see detail in Component Head
[options.compilerConfig]	`Object`	server-side compiler webpack config, default config use `vue-loader` with `css-loader` and `babel-loader`
[options.onError]	`Function`	error handler
[options.onReady]	`Function`	ready event handler, renderer will emit an event when completed the work of initialization
[options.global]	`Object`	global variables, these variables will be injected into context of the vue rendering sandbox, just like global.xx in node or window.xx in browser

Vue Client Plugin

We can set the render data to vue instance data with the client plugin

Base usage

import Vue from 'vue';
import vueEasyRenderer from 'vue-easy-renderer/lib/plugins/client';
import App from './app.vue';

Vue.use(vueEasyRenderer);
const app = new Vue(App);
app.$mount('#app');

Component Head

We can set head in component

<template>
  <div id="app" class="hello">hello {{world}}</div>
</template>
<style scoped>
</style>
<script>

  export default {
    name: 'HelloWorld',
    data() {
      return {
        world: ''
      };
    },
    head: {
      title: 'hello',
      script: [
        {src: "/hello_world.js", async: 'async'}
      ],
      link: [
        { rel: 'stylesheet', href: '/style/hello_world.css' },
      ]
    },
  }
</script>

Then the result

<html>
<head>
 <title>hello</title>
 <link rel="stylesheet" href="/style/hello_world.css"/>
 <script>window.__VUE_INITIAL_STATE__ = {"world":"world!"};</script>
 <script src="/hello_world.js" async="true"></script>
</head>
<body>
  <div id="app" server-rendered="true" class="hello" data-v-035d6643>hello world!</div>
</body>
</html>

vuex or vue-router

When using vuex or vue-router in server-side rendering, we need to create a vuex or vue-router instance for each request, so when you inject a vuex or vue-router instance into a component, you need to add a factory function to the instance , The function will return an instance when called, the default method is named $ ssrInstance, such as:

vuex

const options = {
  state: {
    hello: 'world!'
  }
};

const store = new Vuex(options);
store.$ssrInstance = () => new Vuex(options);
export default store;

vue-router

const options = {
  mode: 'history',
  routes: [
    { path: '/user/:id', component: User }
  ]
})

const router = new VueRouter(options)
router.$ssrInstance = () => new Vuex(options);
export default router;

If you use vue-router in server rendering, you need to set mode to history
