Egg-nuxt-merge

Plugin for merging nuxt into Egg.js

Features

Make nuxt and Egg.js listen in one server but they are in separated preojects. Nuxt renders pages in the middleware of Egg.js, so cookies can be correctly set by Egg.js(especially CSRF plugin is enable)

• app.nuxt | ctx.nuxt returns nuxt object
  use await ctx.nuxt.render(ctx.req, ctx.res) to render page explicitly; by default it always render page unless config.nuxtMerge.ignorePrefix or config.nuxtMerge.matchPrefix were set

Install

Use npm link or yarn link to link nuxt app into egg app(optional)

$ cd /path/to/nuxtApp
$ yarn link
$ cd /path/to/EggApp
$ yarn link {Your Nuxt App Name}

Notice template of nuxt app requires to be chosen as pure
Nuxt app should return a function which generates nuxt object from entry file in package.json

// index.js in nuxt app root path
// depends on configs in package.json

const cwd = process.cwd()
const { Nuxt, Builder } = require('nuxt')

// Import and Set Nuxt.js options
const config = require('./nuxt.config.js')

module.exports = async function(cfg) {
  process.chdir(__dirname)
  // Instantiate nuxt.js
  config.dev = cfg.dev
  config._start = !cfg.dev
  const nuxt = new Nuxt(config)

  const {
    host = process.env.HOST || '127.0.0.1',
    port = process.env.PORT || 3000
  } = nuxt.options.server

  // Build in development
  if (cfg.dev) {
    const builder = new Builder(nuxt)
    await builder.build()
  } else {
    await nuxt.ready()
  }

  process.chdir(cwd)
  return nuxt
}

Because we changed process.cwd, no need to install any nuxt dependencies in Egg app. process.cwd will be reset after compiling nuxt app

Settings in Egg app

// in config/plugin.js
exports.nuxtMerge = {
  enable: true,
  path: path.join(__dirname, '../app/plugin/egg-nuxt-merge')
  // or via package
}

Then add your nuxt app package name or path to config

// in config/config.***.js
config.nuxtMerge = {
  appPkg: '{Your nuxt app package name}',
  ignorePrefix: '/api/v1'
}

If your apis have a route prefix, you can add an ignore prefix to the config of this plugin

Configure

• nuxt app path exports.appPath
  Path to nuxt app root, absoluted or relative(to egg app base dir) are both OK
• nuxt app package exports.appPkg
  Your nuxt app package name; if you link nuxt app via yarn link, the package name is the nuxt app base dir name
• ignorePrefix exports.ignorePrefix
  Ignore some queries. See here for general config of middleware
• matchPrefix exports.matchPrefix
  Only enable as query path is matched. Click the link above for more details

Notice

In prod environment, you need to build nuxt app at least once manually via npm build in nuxt app before running npm start in egg app
ignorePrefix will overwrite matchPrefix settings
