NextJS with Express : copying files to server and running “npm run start” fails

由 核能气质少年 提交于 2020-03-25 13:00:27
问题 I am creating a NextJS application and I want to copy ONLY the production files to my server and deploy the application. This works perfectly fine when I do NOT use Express, however when i do use Express the app no longer runs on the server as it says it can not find the "pages" directory. Project structure |- .next |- client |- polyfills.js |- components |- CompA.js |- CompB.js |- etc |- node-modules |- ... |- pages |- index.js |- page1.js |- page2.js |- etc |- public |- appIcon.png |-

3 月，跳不动了？>>> CentOS系统环境： 安装开始： 1、 wget http://nodejs.org/dist/v0.10.15/node-v0.10.15.tar.gz #若提示wget command not found，可直接复制此链接下载安装包，后面的步骤一样。 tar zxvf node-v0.10.15.tar.gz cd node-v0.10.15 ./configure make && make install 2、 配置的时候出现如下错误： fpu = 'vfpv3' if armv7 else 'vfpv2' 引起此错误的原因是Python的版本过低，升级到2.7即可： wget -c http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2 #同上 tar jxvf Python-2.7.3.tar.bz2 cd Python-2.7.3 ./configure make && make install python2.7便安装成功，路径：/usr/local/lib/python2.7。 3、重复步骤一即可，安装成功。查看node.js的版本信息： 4、写个示例代码测试node.js能否正常运行： var http = require('http'); http

How to check is user already exist with customValidators in express-validator?

由 醉酒当歌 提交于 2020-03-23 12:38:52
问题 I have a problem to return boolean (true or false) if user already exist or not in custom express-validator. So far I manage to work it in this way: app.use(expressValidator({ customValidators: { isUsernameAvailable: function (username) { return User .findOne({ 'username': username }) .then(function (user) { if (user) { throw new Error('User already exist') } } } } The idea is to return boolean (corresponding the name: isUsernameAvailable) not Promise or Object, but I don't know how.

Appending a JSON file from JS file in Express Application

由 拥有回忆 提交于 2020-03-23 07:49:09
问题 This is a learning struggle, and I might just be approaching this from an awkward angle, but guidance is appreciated. This project is using just HTML, Node, and Express. I have a small app that is supposed to take survey inputs to build a 'friend' profile (essentially only a name, imgURL, and 7 question answers each a value 1-5). I want to save all the Friend objects with those properties in a JSON file in a data sub-directory so that as new users are added, I can compare the friend objects

由 匆匆过客 提交于 2020-03-23 02:24:50
问题 I have a Node.js server that I am sending a web socket upgrade request to. The Authorization header of this request contains login information, which I need to compare against a database entry. I'm unsure how I can stop the web socket connection from opening until after my database query callback is executed. The following is a simplification of what I am currently doing: var Express = require('express') var app = Express() server = app.listen(app.get("port"), function () {}) server.on(

问题 I have created a simple node app using the express framework using JADE templating.
