heroku - 如何在 heroku 上部署 reactjs + nodejs(restify)+ postgresql 应用程序？

问题描述

我已经使用 reactjs、nodejs(restify) 和 postgresql 创建了应用程序，我在 Heroku 上成功构建，但是当我打开我的应用程序时，我收到错误{"code":"ResourceNotFound","message":"/ does not exist"}我我尝试添加 serverStaticFiles() 但它给了我AssertionError [ERR_ASSERTION]: directory (string) is required所以我现在删除它现在帮我找出我在这里做错了什么......

服务器.js


    var restify=require('restify')
    const { logIn,userCreation, demotable } = require('./routes/Function');
    const corsMiddleware = require('restify-cors-middleware2');
    const { data } = require('jquery');
    const PORT=process.env.PORT || 8080;
    var path=require('path')
    var server=restify.createServer() //server created
    
    server.use(
        function crossOrigin(req,res,next){
          res.header("Access-Control-Allow-Origin", "*");
          res.setHeader('Access-Control-Allow-Headers', 'Content-Type');
          res.setHeader('Access-Control-Allow-Credentials', true); // If needed
          res.header("Access-Control-Allow-Origin", "*");
          res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
          res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
          return next();
        }
      );
    const cors = corsMiddleware({
      preflightMaxAge: 5, //Optional
      origins: ['*'],
      allowHeaders: ['*'],
      exposeHeaders: ['*']
    })
    
    server.pre(cors.preflight)
    server.use(cors.actual)
    //setting
    // if (process.env.NODE_ENV === "production") {
    //   //server static content
    //   //npm run build
    //   server.use(restify.static(path.join(__dirname, "client/build")));
    // }
    
    console.log(__dirname);
    console.log(path.join(__dirname, "client/build"));
    //get data from login form
    
    server.post('/note', userCreation);  
    server.use(restify.plugins.bodyParser());
    server.get('/login',logIn)
    server.get('/employees',demotable)
    
    if(process.env.NODE_ENV==='production')
    {
      server.get('/client/build/*', restify.plugins.serveStatic({
        directory: __dirname,
        default: 'index.html'
       }));
    
    // server.use(restify.serveStatic('client/build'))
    // server.get('*',(req,res)=>{
    //   res.sendFile(path.join(__dirname,'client','build','index.html'))
    // })
    }
    // server.get("*", (req, res) => {
    //   res.sendFile(path.join(__dirname, "client/build/index.html"));
    // });
    server.listen(PORT, function(){
        console.log("server started...")
    })
