我已经尝试部署我的Mern应用一个月了。没运气！
我检查了数百个：“无法在heroku上部署Mern”，“完整指南，让我们在Heroku上部署Mern应用程序”找不到有效的解决方案。部署不会失败，但是应用程序立即崩溃。
因此，我使用client / src中的setupProxy文件进行调用以表达开发中的路由。
我尝试了package.json脚本的所有可能方式。所以现在我什至不知道在那里需要哪个脚本。
我也有proc文件，其中有一行代码：
web: node server.js
我的package.json中的脚本现在：
"scripts": {
"build": "npm install --prefix client && npm install",
"client-install": "npm install --prefix client",
"start": "node server.js",
"server": "node server.js",
"client": "npm start --prefix client",
"dev": "concurrently \"npm run server\" \"npm run client\""
}
这个还不能正常工作：
"scripts": {
"heroku-postbuild": "cd client && npm install && npm run build",
"start": "node server.js",
"server": "node server.js",
"client": "npm start --prefix client",
"dev": "concurrently \"npm run server\" \"npm run client\""
}
我的server.js：
// Loading env variables into our APP.
require('dotenv').config();
const fs = require('fs');
const express = require("express");
const app = express();
const passport = require("passport");
const bodyParser = require("body-parser"); //body parser allows us to take data from forms and use req.body.parametr ex: req.body.name
const mongoose = require("mongoose");
const flash = require("connect-flash");
const cookieParser = require('cookie-parser');
const cookieSession = require("cookie-session");
const path = require("path");
// Connecting to DB
mongoose.connect(process.env.MONGO_URI)
.then(() => console.log("MongoDB successfully connected"))
.catch(err => console.log(err));
// EXPRESS APP CONFIGURATION:
// Parsing data from the forms! This step is super important in order for passport to work.
app.use(bodyParser.urlencoded({
extended: true
}));
app.use(bodyParser.json());
app.use(cookieParser());
// Express session creates a new session each time we logIn
app.use(require("express-session")({
secret: process.env.XPRESS_SEC ,
resave: true,
saveUninitialized: true
}));
// Setting default Engine and default directory.
app.set("view engine", "ejs");
app.use(express.static("public"));
app.use(flash());
// AUTH flow with Passport.
// Calling Passport to initializa and create a session.
app.use(passport.initialize());
app.use(passport.session());
// Creating a function that will check if user loged in or not.
app.use(function(req, res, next){
res.locals.currentUser = req.user;// req.user will either be empty or contain information about user from the request
res.locals.error = req.flash("error");
res.locals.success = req.flash("success");
next();
});
//CRUD ROUTES
require('./routes/api/authRoutes')(app);
require('./routes/api/itemsRoutes')(app);
// PASSPORT.js CONFIGURATION IMPORT
require("./services/passportConfig")
// Right before your app.listen(), add this:
app.get("*", (req, res) => {
res.sendFile(path.join(__dirname, "client/build/index.html"));
});
app.listen( 5000 || process.env.PORT, process.env.IP,function(){
console.log("Server had been started")
});
那是heroku tail的输出
