I have developed node rest api and vuejs web applications,
Im trying to deploy both project in to one aws server which run ubuntu.
Both applications have different port,
domain I try to configure api.example.com for api and example.com for vue app.
I can run both applications once after running the command in SSH, but I need them to run it forever.
What I did,
Deploy to apps separately
Apps can access with ports
I need them access
api.example.com
example.com
what are the step to do,
Any changes host file.
I found another way to deploy vue app and express/nodejs in one server without using PM. This what I did
Build your vue code using npm run build command. This will create a folder dist which should have index.html file and static folder.
Copy dist folder into your server code repository. In my case I created a folder public and moved the dist folder inside public.
In app.js file right before module.exports=app line, copy the following lines of code
//These 2 lines make sure that vue and express app are coming from the same server.
app.use('/static', express.static(path.join(__dirname,"../public/dist/static/")));
app.get('/', function(req,res) {
res.sendFile('index.html', { root: path.join(__dirname, '../public/dist/') });
});
First line make sure that the /static folder is accessible and second line will serve the index.html file when you run the node server. Routing between components will be taken care by vue.
This is how we are running our VueJS UI and ExpressJS REST API from the same server.
We are managing our services with PM2.
VueJS (Dev Environment, You can add the same settings to production)
In package.json add "start": "HOST='0.0.0.0' PORT=80 npm run dev",, where 80 is the port VueJS is listening on, to the "scripts": {..} array. Then, after installing PM2, (for dev) we can start VueJS with cd /location/of/vue/root; sudo pm2 start npm run dev --name Vue -- start. (Make sure that Apache is not running).
Please note that setting the HOST to 0.0.0.0 is important. Do not set it to LocalHost or your Servers IP address or you may run into issues.
ExpressJS
In the /location/of/express/app.js add this similar to the bottom of the file:
app.listen(process.env.PORT || 8081), where 8081 is the port your REST API should be listening on. I can then start it with sudo pm2 start /location/of/express/app.js --name Express
At this point, the VueJS should be available at www.example.com (implied Port 80) and the REST API would be available at www.example.com:8081.
If you want to have api.example.com/ point to the API, you need to make sure that your DNS is pointing the "api" subdomain to the desired port, or you may have to add the port into the URL as above.
Additionally, you can easily follow the logs through PM2 as well with pm2 logs APPNAME --lines 100.

I'm trying to set up a reverse proxy on the development server for my VUE js webapp to get around the CORS issue that I was getting when I was trying to use my flask HTTP APIs with the vue js webapp.
I did this by creating a vue.config.js file in the root of the project directory:
module.exports = {
devServer: {
proxy: 'http://localhost:5001/'
}
}
when I run npm run serve, and try to use a REST API defined on port 5001 - I don't see the request going to port 5001, it uses the same port as the web app.
And there are no useful logs being written to stdout either to help me debug this.
Has anyone come across this issue before ?
I had a similar issue and found that the port was already in use by another application and hence it was not going to the correct port. Once i shutdown the other app, it started working as expected.
I have created a project using angular-universal.
after building the project it created browser, server, server.js and prerender.js. I want to know how it can run on the nginx.
with the current scenario i create the build of the project send it's zip file to the /var/www/html and unzip it there and it runs.
Make sure your angular ssr project is running on same port , which you domain is listning to in nginx configuration file.
By default it listnes to 80 port , you need to change that port number in nginx configuration file and restart the server.
I am new in the software field, please have patience with my question and mistakes of technical terms:
Premises:-
I have developed an front-end application using Angular4. The baseURL define in angular application is 'http://localhost:3000/'. My application uses restangular api to interact with json-server (I created a folder named json-server and it has db.json and public folder ). It is working perfectly fine when i start the json-server using command:
json-server json-server --watch db.json
My application is finalized and thus I created a production build. Thereafter I moved all my files from dist folder to public folder of json-server. When i start the json-server, my application works fine.
Actual problem:-
Now I wanted to host in azure. I simply copied all file/folder (db.json and public folder) from json-server folder as it is and put them in azure cloud. When azure hosting is done and I open the url in browser I got an error- "you don't have permission to view".
To rectify above error I deleted all files from azure and then I copied all files of dist folder and put them in azure cloud. Using this I could able to see the application in the browser but no images. At image there is an error- Response with status: 0 for URL: null
When I start json-server locally, everything works fine but of course when same web page open from other machines I got the same error- Response with status: 0 for URL: null
Is there any way to run json-server in azure so that all machines/mobile when accessing the url, can see proper web page without any error.
Step to step to run json-server on Azure Web App:
Open your browser and go to App Service Editor (https://<your-app-name>.scm.azurewebsites.net/dev/wwwroot/)
Run the command in the Console (Ctrl+Shift+C)
npm install json-server --save-dev
Put all file/folder (db.json and public folder) into wwwroot folder
Create a server.js with the following content
const jsonServer = require('json-server')
const server = jsonServer.create()
const router = jsonServer.router('db.json')
const middlewares = jsonServer.defaults()
server.use(middlewares)
server.use(router)
server.listen(process.env.PORT, () => {
console.log('JSON Server is running')
})
Click Run (Ctrl+F5), this will generate web.config file automatically and open your website in the browser.
You can use the following to quickly setup a mock service which can serve REST APIs off static JSON files.
json-server
Just install the NodeJS module ($npm install -g json-server). Populate a static json file in the format attached and then run the JSON server ($ json-server --watch db.json --port 3000)
I have an html file that has resources in it's directory
(example file tree)
index.html
imgs
>img1.jpg
>img2.jpg
>img3.jpg
js
>js1.js
>js2.js
How do I run a node.js server that will allow me to view the HTML file, as well as allow me to access certain websites with the access-control-allow-origin *
I am unfamiliar with node, so the simpler, the better!
Extra: does not necessarily have to be node, just a server that will allow access control
Since You're learning and starting from scratch so it's preferred to learn how it's done than installing supper-pupper swiss knife toolset that will hide the logic from You and make You boring lazy developer.
If You just want to achieve quick result and don't want to learn - You may use serve package that will do what You need.
But if You're learning nodejs from zero to hero so read my answer.
It's better to do simple things.
Let's go (:
Create some folder and inside of it do following commands in terminal (or cmd in windows os):
1) Init app:
npm init
2) Install express module:
npm i --save express
3) Install cors module/middleware:
npm i --save cors
4) Create public folder and put Your html files there
5) Create app.js file in sibling folder with public:
"use strict";
const
express = require('express'),
app = express(),
cors = require('cors');
app.use(cors()); // attach cors middleware (must be set before of most route handlers to populate appropriate headers to response context)
app.use('/', express.static('public'));
app.listen(8080, () => console.log('APP STARTED'));
6) Run it: node app.js
7) Open in browser: http://127.0.0.1:8080
for more stuff search in YouTube for nodejs express tutorials, nodejs mean stack tutorials and etc. (:
For a quick resolution it can also be checked, the Chrome Web server app, for creating local server allowing access to the local files over localhost server.

I have started a react application using create-react-app and ran the npm run eject script to gain access to all files. I afterwards installed express and created server.js file that sits on same level as package.json file
these are server.js file contents:
const express = require('express');
const app = express;
app.set('port', 3031);
if(process.env.NODE_ENV === 'production') {
app.use(express.static('build'));
}
app.listen(app.get('port'), () => {
console.log(`Server started at: http://localhost:${app.get('port')}/`);
})
Nothing crazy here, just setting up for future api proxies where I need to use secrets and as I don't want to expose my api.
after this I added a "proxy": "http://localhost:3001/" to my package.json file. I am now stuck as I need to figure out how to start my server correctly and use this server.js file in development mode and afterwards in production.
Ideally It would also be good if we could use more that one proxy i.e. /api and /api2
You didn't have to eject to run your server.js. You can just run it with node server.js together with create-react-app.
You can still do npm start even after ejecting to start your dev server.
To run /api1 and /api2, you just have to handle it in your server.js file and it should work just fine. You need to match the port in your server.js and the one in proxy settings inside package.json - in this case, it should be "proxy": "http://localhost:3031"
