node.js - 在heroku上部署Nodejs+Express+React+Webpack应用程序

我使用 Node js、express、webpack、react 和 socket io 制作了一个 Web 应用程序,我想将其部署在 heroku 上。当我尝试时,我可以访问该网站,但它显示一条错误消息:

Cannot GET /

这是我的配置:

    "scripts": {
"start": "npm run dev",
"build": "webpack --mode production",
"client": "webpack-dev-server --mode development --devtool inline-source-map --hot",
"server": "nodemon src/server/index.js",
"dev": "concurrently \"npm run server\" \"npm run client\"",
"heroku-postbuild": "NPM_CONFIG_PRODUCTION=false npm install && npm run build"
}

在我更改之前,启动脚本是 node src/server/index.js,因为我运行 npm run dev 在本地启动我的应用程序。

这是我的存储库:http://git.kamal-allali.fr/kamal/prog_web_5a

这里是 Heroku 链接:https://fast-earth-60949.herokuapp.com

最佳答案

您需要将 Node 版本添加到 package.json 中。

示例:

  "engines": {
"node": "10.11.0"
}

我在评论中回答了,但这不是最好的方法,所以我会在这里编辑。

由于您正在尝试提供静态内容,请尝试使用静态中间件。

删除

app.get('*', (req,res) =>{
res.sendFile(path.join(__dirname,'../../public/index.html'));
});

并添加

app.use(express.static(path.join(__dirname,'../../public')));

第二次编辑。

您需要构建项目并提供文件夹,通常是 dist 或 build 文件夹。

要做到这一点,您有几个选择,其中之一是在将更改发布到 heroku 之前构建项目,但这可能会有点乏味。

另一个选项是执行安装后脚本,以便在 heroku 执行 npm install 后构建项目,并使用最新更改创建 dist 或 build 文件夹。

"postinstall": "npm run build"

如果您不希望每次执行 npm install 时都运行脚本,您可以在 heroku 中使用 if-env 和环境变量。

"postinstall": "if-env NODE_ENV=production && npm run build"

一旦您知道构建时正在创建哪个文件夹,请更改下一行。

app.use(express.static(path.join(__dirname,'path to the folder with the prod build')));
