启动mongodb和express的正确方法? [英] Correct way of starting mongodb and express?

问题描述

我有一个可以在express上运行并与mongodb通信的应用程序.这是我启动应用程序的方式:

I have an app which runs on express and communicates with mongodb. This is how I start my app:

1.启动Mongodb

mongod --dbpath data --config mongo.conf"

2.启动Express

node server.js

我的问题是，有没有办法将这些结合起来?我知道节点是单线程的，所以我们不能同时从server.js运行express和mongo，但是正确的方法是什么?可以使用npm从JavaScript文件启动mongo吗?

My question is, Is there a way to combine these? I know node is single threaded so we cant run both express and mongo from server.js but what is the correct way? Is it possible to start mongo from a javascript file using npm?

我可以在两个不同的命令提示符下分别运行 mongo --dbpath数据和 node server.js .我的问题是从一个文件(如果可能)启动它们.

I can run mongod --dbpath data and node server.js separately on two different command prompt. My question is to start them from one file (if possible).

推荐答案

start在Windows中创建新的cmd 这是我的配置:

start creates new cmd in windows here is my config:

"scripts": {
  "prestart": "start mongod --config ./data/mongod.cfg",
  "start": "node ./server/bin/www",
  "poststart": "start mongo admin --eval \"db.getSiblingDB('admin').shutdownServer()\"",
  "pretest": "start mongod --dbpath data",
  "test": "mocha test",
  "posttest": "start mongo admin --eval \"db.getSiblingDB('admin').shutdownServer()\""
},

祝你好运！
