1. step 1： 修改 angular.json
修改 angular.json 文件中的 outputpath: dist/aaa-sys 改为 outputpath: pack/aaa （pack/aaa 是自定义的目录名）
2. step 2 ： 修改environment.prod.ts文件
修改environment.prod.ts文件，增加apiUrl参数，如下所示：
export const environment = {
production: true,
apiUrl: 'http://localhost:3000/api'
};
注意：在部署到远程服务器的时候，localhost要改为主机对应的IP地址
3. step 3 ： 运行 ng build - -prod 进行打包
执行命令的时候，可能会出现错误：appears “property 'controls' does not exist on type 'AbstractControl'
解决方法: 找到相应的.html文件，把.myForm.controls['address'].controls 格式改为.myForm.controls['address']['controls']
运行 ng build - -prod 重新进行打包
4. step 4 ： 修改 app.js
修改 app.js
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({extended: false}));
app.use('/images', express.static(path.join('pack/images')));
在以上代码后面添加如下代码：
app.use('/', express.static(path.join('pack/aaa')));
app.use((req, res, next) => {
res.sendFile(path.join(__dirname, "aaa","index.html"));
});
注意：aaa 是你打包的名称，部署的时候，只需要拷贝pack包即可
5. step 5：mean 启动
npm run start:server
start:server
package.json "start:server": "nodemon server.js"
server.js express 监听端口
const app = require("./pack/app");
const debug = require("debug")("node-angular");
const http = require("http");
const normalizePort = val => {
var port = parseInt(val, 10);
if (isNaN(port)) {
// named pipe
return val;
}
if (port >= 0) {
// port number
return port;
}
return false;
};
const onError = error => {
if (error.syscall !== "listen") {
throw error;
}
const bind = typeof port === "string" ? "pipe " + port : "port " + port;
switch (error.code) {
case "EACCES":
console.error(bind + " requires elevated privileges");
process.exit(1);
break;
case "EADDRINUSE":
console.error(bind + " is already in use");
process.exit(1);
break;
default:
throw error;
}
};
const onListening = () => {
const addr = server.address();
const bind = typeof port === "string" ? "pipe " + port : "port " + port;
debug("Listening on " + bind);
};
const port = normalizePort(process.env.PORT || "3000");
app.set("port", port);
const server = http.createServer(app);
server.on("error", onError);
server.on("listening", onListening);
server.listen(port);
