Deploy ReactJS & ExpressJS to Nginx - reactjs

I have a typical Ubuntu VPS setup (20.04LTS) where I have installed the Nginx Server.
I have two local repos with front-end reactJS code repo and back-end ExpressJS code repo.
I will start the ExpressJS on the 3000 port with forever start. I have also a mysql db.
I have configured Nginx to server the static files with the root /var/www/[Your repo name]/build; and I can open the html files and it is working.
The question is, do I need to start on another port for an example the ReactJS npm run start or is Nginx enough? Could you help me out with some links or best practices?
Thanks in advance.

If you're using CRA (create react app), it ships with a build script, so after running npm run build the whole app is built into static files including a index.html and some js and css files. all you need to do is to config nginx to serve that index.html. so nginx is enough for that. if you're using react-router in your app keep in mind that you may need to use try_files directive of nginx for serving that index.html for any incoming requests.
for more information about react-router and nginx see this.
If you're doing SSR (Server Side Rendering) you need a process manager like pm2 or forever to serve your app internally and proxy_pass directive of nginx to reverse proxy incoming requests to your app. More info

All the static files like index.html and assets will be served from your "root /var/www/[Your repo name]/build" folder, when the user opens your base url and sent as response for the get call. From your code, make sure to append '/api/' to all your backend requests from ui, so that it will get forwarded to your service running on port 3030.

Does npm server is necessary for ReactJS with django on production?

I have developped the application with DJango + ReactJS
when in developpment,
using
$python manage.py runserver
and
$yarn start
which launche the two servers on localhost:8000 and localhost:3000
However in production environment, I need to launch two servers??
When I use webpack before I run two server in developpment environment, but in Production just building in advance and use only on one server uwsgi
Could run under one server directly, I'll share other ways too.
Have your yarn build done and serve under Django's static files + listen for js/css/image assets. Now about your routing, you need to capture frontend routes such a way that (when direct url is entered), Django responds back static assets itself.
The downside in above is that your APIs' urls have to be following some pattern which won't interfere frontend URIs (routes).
Running two servers + CORS
Pack your react build with expressjs and serve it with some production grade server like pm2/ could use nginx + static files too but to tackle routes issue (of React), you'll need to tweak nginx to listen to not only "/" but also other routes in frontend.
Now, calling django APIs, do enable CORS config to support calling APIs from your React site.
Can also use serverless to send your static files + CORS behind the scenes.
If you're not having access to root of server, would need extra one to spare in former case. Otherwise to spin up a frontend + backend process in same server machine won't do much weight.
Good luck!

React Github page not working as expected

I have create created a react app for ticket management and for connect with backend i have defined proxy in package.json as shown in the figure. this is finely working in local host. when i publish to github page, it not able to connect to backend and get 404 error since the proxy in package.json is not considering now. So how i define a proxy as like in the packag.json to github page i have hosted
github ripo: https://github.com/pranavmappoli/supportdesk
hosted page: https://pranavmappoli.github.io/supportdesk/
backend URL: https://pranavhelpdesk.herokuapp.com/
how could i resolve this issue other than putting the path in .env file
The webpack proxy is designed to be used as a hack during development.
In production you are supposed to configure CORS on the API or deploy the app to the same origin as it so you don't need a proxy.
An an alternative (not one I'd recommend) you could build a production ready proxy. If you do that then it will need to support CORS and cannot be hosted on Github pages which only support statics files.

How to deploy react application in a sub-directory using AWS Load Balancer

I have been trying to run my react application on a subdirectory .
I am using a load balancer (ALB) to and redirecting my application on "directory" from "https://mydomain/directory".
But static file of the build was not being found by my application
added direcctory on package.json. "homepage": "/directory"
added basename on react-router-dom
in my networks index.html is looking for ".#####/directory/static/js" and css in the same way
i am only able to run my react build by redirecting static request to my react build, but this is not the good solution because i want to run 3 applications on my ALB and this will cause me change my assets folder name manually in the build, obviously don't want to do that.
I have been applying multiple solutions but couldn't find a proper solution please someone help in this.😑
ALB doesn't do redirects, and it doesn't do any sort of request path rewriting, it simply forwards the request to the target. You need to setup your server so it is actually serving the website from that folder, in other words change your assets folder name in the build.
If you don't want to do that, you would need to look at other AWS solutions like CloudFront which can proxy the request to a different path on the origin server.
I had a scenario of publishing react app with nginx inside docker with ci/cd. It took me setup a separate express server to serve app files and resolved the issue. Here is the repository synopsis of server.js that might help:

React web is not working properly after build (related axios api)

I use
"webpack": "3.8.1" ,
"react": "^16.5.2"
when start to yarn start app is working
but after the yarn build and serve -s build, not to call api. (but react-router is working)
In other words, it does not work for the http request. After the build
But as a yarn start, http request runs well.
(I use proxy in package.json. front-end is react, backend is spring boot)
I suspect your issue is like this. When you are developing you are using a proxy setup in your package.json as you have stated in your question.
When you have this proxy setting, webpack dev server will proxy your request from the client to the server. This is what allows you to leave the baseurl off your request in the app. In other words, because of this proxy you can simply write /api/endpoint/.
When you build and serve using the serve module however, webpack dev server is no longer the one serving your app the the browser, which means there is no more proxying requests from client to server. This means you are making a request to just /api/endpoint/ which means there is no server actually getting your request.
Without actually changing your react code to use the full url including the base url in requests, you would need to actually have the server be responsible for serving the build folder to the web statically. By doing this, your /api/endpoint will point back the server that served the app which is also your api.

Create react app with docker and nginx

I've been trying to deploy a react app to a server using docker, nginx and create-react-app
This is my setup
nginx container -> multiple dockers(One of them is the react one)
This is the nginx conf
location /mycms {
proxy_pass http://MyCMS:5000;
}
MyCMS is the docker container running serve correctly. Both the nginx and the container are on the same network.
The issue I'm having is that every time I go to https://myweb.com/mycms I get served a blank page and every .css and .js request returns the index.html of the app.
I've tried setting the homepage to both "https://myweb.com/mycms" and "." but neither seem to work
Any idea what could be wrong? It works if I run it on my machine without nginx
Regards
Edit:
The server conf is here: https://pastebin.com/BVNVcAEF
