Deploying Mean Stack Application on Heroku Issue - node.js

This is my first time building a MEAN stack application and I built it locally. Now I am trying to host it on heroku and I think I messed it up. I went through different questions here and most of them said both angular and express needs to be in one single app. I din't know that, So here's my current folder structure.
Project Root Folder
|
|
|------ Frontend (Angular App)
|
|
|------- Backend (Express App)
I tried searching everywhere but couldn't figure out what changes I need to make to my current project structure. Any tips or help or even a link to a guide would be much appreciated.

For hosting as a single app
first build the angular app
host the build folder of front end in the backend express app as
app.use('*', express.static('Frontend/build/'))
in start script of backend build the angular app and start the server file(index.js)
inside the server file use port from the environment variables, heroku will automatically assign you with an port which will be pointed to the dynamos url

How to deploy GitHubPages when it is connected to mongodb atlas?

I have created sample angular application to test GitHubPages deployment..
Backend has a node js code which is connected to MongoDB Atlas.
Frontend has angular which is working fine when starting backend and frontend both.
When I build project, it has fully angular component only.. So I moved to backend into frontend folder and which is now
still when I build and I need to copy paste the database component and dist in one single folder.
If I do that npm install and node index.js it is working fine..
The same i am trying to do in GitHubPages using Actions. until dist folder is fine.. How to move database backend files in to ghPages to up the service. without db files i except html page but showing 404. How to copy db files from master to ghpages branch.
My repository is given https://github.com/changan1111/UserManagement
Any help would be really appreciated.
Github pages can only serve static files (HTML,CSS, js, images, etc.)
It might serve your bundled Angular application, but your API calls will need to be done to a hosted backend.
You can check Google Cloud, AWS, Heroku, Azure for hosting the backend.
Be sure to set CORS properly.

Making my React app working with a Server

I have a question and got confused with the articles I found on the internet.
I have a react App which deploys on the development server. I want to create an admin part, where the administrator will be able to push content into the database. React App will get content from a Database and render it.
Also after the development, I want to upload this on hosting so users from the internet can have access to it and use it. I understand how the server works with post\get requests from glitch projects.
Writing on React.Js, server with express.js
So can someone explain to me the following:
how the server sends React app? Should I send simple index.html with #root div and the whole website will work?
I am a bit confused about how hand-made server and API are different from hostings? How to connect then backend with a hosting?
IN VSCode is it possible to make a react App showing from the server of Node.js? - On glitch I can
sendfile index.html with simple request and I see the landing page.
So theoretically I should have a possibility to send static file through a server of Node.js/Express.js?
Can you explain these questions to me, please or provide some resources where it explained? Currently I'm watching Youtube and Google but how to connect it with my project I do not get a clear idea.
Pretty much. If you use create-react-app to build your React frontend, the build result folder will contain all the static files required (HTML, CSS, JS, images, fonts...). You can then either have your Express app serve it as static data.
"Hosting" is a nebulous term... No, you can't upload a Express/Node.js app to some PHP web hotel and expect it to work. You'll need an application-hosting centered provider/PaaS such as Heroku.
When developing a react + backend app locally, you'd have your backend server running, and the frontend dev server up to serve your frontend and configured to proxy all API requests to the backend server (like this, via the Create-React-App docs).

Deploy a React app + Node server with Heroku

I want to deploy a project (React app + Node server), but I'm new to deployment,
I wanted to know : do I need to have the React app in a Github repo and the Node server in another, or I can deploy all in one ?
Currently, I have 1 Github repository with a folder "frontend" and an other "backend",
I want to have my React app on -> nameofmyapp.herokuapp.com
and the Node server on -> api-nameofmyapp.herokuapp.com,
If someone got ideas... Thanks
While in theory that's not a problem, I would suggest maybe considering keeping things on one domian for reasons such as additional latency and connection trouble as well as path issues such as you are facing. It would seem to me that you would ideally just like to prefix the name of your app with 'backend' or similar and in such a case I would just consider setting up a sub domain on a domain which I had control ie mydomain.com and backend.mydomain.com. While developing on Heroku this model could prove to be tricky as each 'site' or app is separate and not actually intended to work together while they most certainly could. Consider setting up separate routes and an endpoint for 'backend' on your app, similar to your frontend login, then when you are finished developing your app and happy you could register your domain name and point it to your app and point a subdomain ie backend.mysite.com or login.mysite.com to your endpoint on Heroku ie mysite.com/backend. Unless you have a specific reason for separating them into their own repos with separate source control and urls, it might make debugging things much harder. Apologies if I missed your point. Most web hosting companies should allow you to register a subdomain or vanity domian free or charge because you own the primary domian. Just some considerations.
Anything is possible, you just need to understand how things are working... my advice would be that you start simple and have a single repo that contains front+back, you can then deploy that as a single Heroku app.
One app can only have a unique Heroku url, so you cannot have what you mention nameofmyapp + api-nameofmyapp hosted by a single Heroku instance, this would need to be hosted by two different instances, which means code from two repos.
Usually for a node app, you would create an /api route that is hosted by the same app, so you have your frontend served at nameofmyapp.herokuapp.com and your api at nameofmyapp.herokuapp.com/api with some sub routes, for example nameofmyapp.herokuapp.com/api/items.
You should be able to easily find tons of Node/React/Heroku tutorials on the web, just play a bit with it to experiment and build some understanding of how those are working together.

Can I put front end app in an external folder in Heroku and serve it on request?

I have a Node server and a React app compiled into its 'public' folder. My host is Heroku (a must for me).
My problem is that whenever I compile a new change on the React app I need to re-deploy the server.
Is there any way in Heroku to store the front end outside the server so that when I push a new code to the front end the server doesn't re-deploy?
Probably a bucket of some sort, or a server router that redirect calls depending on URL? Or any other solution?
Thanks!
Edit: I found an answer. It's called 'Bucketeer' in Heroku. It's the same S3 bucket from AWS. However, this is mainly for storing bulks of data, and it might not be fast enough to serving static app. So if you have any better idea I would appreciate sharing it.

Heroku / Node / React - how to access my node api endpoints on heroku

Edit: I can share either of my package.json files if that helps.
Edit2: I dont know if this is a common question or a dumb question. I know it doesn't fit stackoverflow, but I've been struggling with this heroku deploy for the better part of a day already.
I recently followed the following tutorial on posting a react / express app to heroku, and while I think I have been successful, I am confused as to how I can access my API. For reference, a couple of relevant steps in the tutorial are:
Create Node / Express API, push to heroku, and check that it works (by going to the api endpoints in the URL and literally seeing the data), and add "start": "node index.js" to the Node package.json file.
Create React App inside of the root directory of the Node API, add to the react app's package.json this: "proxy": "http://localhost:5000" (I figure so that the api and app can communicate.
I've followed all of these steps, and my React App is working on heroku. The app is displaying, and since the app relies on the Node API to get data to display, clearly the Express/Node API is working.
However, I would like to Actually See the node API endpoints, by going to the endpoint in my browser, and I am not able to do that in heroku currently. All of the React Routes work, however when I visit the api routes my screen is blank. Any thoughts on how i can visit my API endpoints, that are on heroku, in the browser?
For example of my problem:
Localhost Node
when I launch (node index.js) on localhost, I can access my node API endpoints at http://localhost:8080/api/path/to/endpoint
http://localhost:8080/ is root of my node API
Localhost React
when I launch (npm start) on localhost, I can access my react app root at http://localhost:3000/
another one of my react router routes is http://localhost:3000/myreactpage/, which leads to a page of my react app.
Heroku
lets say my heroku app name is https://dusty-manager-23562.herokuapp.com/
https://dusty-manager-23562.herokuapp.com/ leads to the root of my React app
https://dusty-manager-23562.herokuapp.com/myreactpage does lead to my react app page
https://dusty-manager-23562.herokuapp.com/api/path/to/endpoint does not show my data, even though i thought it would / want to see my data. This right here is my question.
So this is my problem. A long post for a simple question - why can't i visit the API endpoint of my node / express app when its pushed to heroku, when I can see the data when its at http://localhost:8080/api/path/to/endpoint. The react app is working, so it's getting the API data correctly, but i want to be able to see the data in browser at the endpoint.
Thanks!
So there are two problems that are probably working in tandem to cause you this headache.
The first and more likely issue is that react-router is intercepting the "/api" urls and deciding prematurely that it doesn't have any components to show for those. A way to fix this is to edit the "proxy" property in your client code's package.json.
"proxy": {
"/api": {
"target": "http://localhost:5000"
}
}
(☝️ I'm assuming here that you kept the 5000 port number from the tutorial. If not change it to 8080 or whatever you used for the api port number.)
The second issue is that the service worker create-react-app adds for you is doing the same thing. It reads the path and thinks there's nothing to serve. If your '/api' route is still showing a blank page, in your browser's dev tools go to the 'Application' tab and click 'Clear site data' (assuming you're using Chrome, not sure how this is done in other browsers) then refresh.
If you don't care about having a service worker, remove the registerServiceWorker() call from your client code's index.js. If you do want the service worker, you'll need to edit the registerServiceWorker.js file to be a little more discerning in how it matches paths.
Hope that helps!
A think this is a relevant post here - Accessing internal API with React, Axios on Heroku
I am not using Axios, but i think the app.get(*) may be giving me issues.
EDIT: no this didn't help a ton actually...
