我已经补充了 react-rails

当前网页包.yml

default: &default
  source_path: app/javascript
  source_entry_path: packs
  public_output_path: packs
  cache_path: tmp/cache/webpacker

  # Additional paths webpack should lookup modules
  # ['app/assets', 'engine/foo/app/assets']
  resolved_paths: []

  # Reload manifest.json on all requests so we reload latest compiled packs
  cache_manifest: false

  extensions:
    - .jsx
    - .js
    - .sass
    - .scss
    - .css
    - .module.sass
    - .module.scss
    - .module.css
    - .png
    - .svg
    - .gif
    - .jpeg
    - .jpg
    - .tsx
    - .ts

development:
  <<: *default
  compile: true

  # Reference: https://webpack.js.org/configuration/dev-server/
  dev_server:
    https: false
    host: localhost
    port: 3035
    public: localhost:3035
    hmr: true
    # Inline should be set to true if using HMR
    inline: true
    overlay: true
    compress: true
    disable_host_check: true
    use_local_ip: false
    quiet: false
    headers:
      'Access-Control-Allow-Origin': '*'
    watch_options:
      ignored: /node_modules/

我在一个终端启动rails应用程序 ./bin/webpack-dev-server

   [1] multi (webpack)-dev-server/client?http://localhost:3035 webpack/hot/dev-server ./app/javascript/packs/server_rendering.js 52 bytes {0} [built]

问题是我跑步的时候 ./bin/webpack开发服务器 每次更新react文件时都会刷新一整页(而不是刚刚更新的组件)。只有在dev server运行时才会刷新整个页面。另外,在整个页面刷新之前,我看不到组件更新。

这就是webpackhmr的工作原理,如果您想在react模块上启用HMR,可以尝试一下 React Hot Loader 和 Webpack plugin

. 安装 react-hot-loader yarn

. 编辑 .babelrc react-hot-loader/babel

import React from 'react'
import { hot } from 'react-hot-loader'

class Example extends React.Component {
}

export default hot(module)(Example);
