I have a web app developed with a NodeJS + Express + GraphQL + MongoDB back-end and a ReactJS + Apollo front-end. I would like to deploy this application locally. Is that even possible?
I have come across dozens of "how to deploy to Heroku," "how to deploy to Digital Ocean", "how to deploy to Github", etc. But none that explains how to deploy locally.
Right now, I run: nodemon server for the back-end, and npm start for the front-end. I see the application running on http://localhost:3000/ (I use cors to connect the front end with the server running on port 3001).
I would like to just go to http://localhost:3000/ and see the app without having to execute the commands npm start and nodemon server. Is this possible? If so, how do I do that?
To my knowledge, our local server is not a WAMP server (our OS is Windows though). The IT department told me that it is a
[...] plain, regular old server. The address is localhost running on
port 3000. You can open up another port on 3001 if you need it. Just
drop your stuff on the C: drive and you should be good to go. I've
never heard of Node or React so I can't help if you have questions.
Any ideas? Many thanks in advance for your help!
UPDATE
There seems to be a bit of confusion surrounding what I am looking for. I am trying to deploy this locally.
Let's say, on your local computer (your laptop at home) you go to localhost:3000 on your favorite browser. Unless you are serving something to localhost in that moment nothing is going to show up, it will say "refused to connect" or something. What I want is to be able to open any machine on the network whenever I go to localhost:3000 and my react site appears and functions...does that make more sense?
I don't want this is development mode. I want a build of this project on localhost...I'm starting to think this isn't possible.
As i understood, you want to deploy it on a local server, not locally on your developing device.
I thought about doing that...but I'm not so sure IT will be okay with it always running... :(
How can you use a server if its not running? Just like WAMP (which runs apache), or whatever you got rolling there, it must be running. So, just make it a background process like slawomir suggested.
PS I dont think you understand node server properly though.
Read this to understand why node server needs reloading. After that you need to understand that no hot reload tool is perfect, and you gonna need to restart your server from time to time.
PPS I dont know what this means
[...] plain, regular old server. The address is localhost running on port 3000.
if there is a server running on 3000, youll need to change port for your server to smth else (most common is 9000)
To solve the problem you can create a startup script, which executes npm start and nodemon server. Then make sure to keep it hidden, so that your server will be always running. Keep in mind though, that any errors thrown will stop your server and unless you configure it, the server won't reload by itself.
I would try following:
build your app with the production environment variables set
get all files from dist folder and deploy them in your server
now access your app using localhost/
Maybe what you are looking for is something like ngrok which creates a socks tunnel to your localhost, effectivelly deploying from localhost, as I understand it, allowing you to access your localhost through a url like ldiuhv093.ngrok.io, or even a custom subdomain if you pay for a subscription fee.
If I have this wrong, someone please tell me!
To solve the problem first of need to create a batch file with .bat or .cmd extension and under that file add the following 2 command
nodemon server
npm start
Then follows the following steps to add it as a startup script for windows OS.
Create a shortcut to the batch file.
Once the shortcut has been created, right-click the file and select
Cut.
Press the Start button and type Run and press enter.
In the Run window, type shell:startup to open the Startup folder.
Once the Startup folder has been opened, click the Home tab at the
top of the folder and select Paste to paste the shortcut into the
folder.
Above steps are for example to create a batch file and add it as a startup script for Windows 8 and 10 users.
For better clarity or reference follows the following link.reference-link
There's no option to reload the server while keeping it running. You could, technically, have your 'main' file monitor another file for changes. This would be the file where you actually keep your sever program. Then, on changes, you discard your current logic and start executing that. That said, doing it that way would be very fragile and a very round-about way to do it. It also wouldn't fix your front-end for which you'd need a similar solution.
Instead, you could hook into your favorite editor's save event, and run those two console commands, so that every time you save, the server is automatically brought up. (Make sure to also clean up existing servers)

I know this post has been two years. But, I think the solution to your second desired outcome is to use concurrency. https://www.npmjs.com/package/concurrently.
This will allow you to do one NPM START to start two all three processes.
and to your first question, I think the solution is to add Electron to your app so you can package it to an executable application. When you start the app, your express server will start running in the background.
Most people probably don't understand why there is a need for this. Running on local server (computer) allows access to local file system and can even run SQL queries inside the proxy which would require IT involvement if hosted on outside server.
From what I have understand, that you want to deploy your app on local server that means you want to deploy it on the network that you are connected to.
Check ip from the command prompt
To deploy it locally,
Run: HOST=ip npm run start
It will get deploy on your local server. And everyone connected to the server can access the url
If this worked for you, kindly upvote
You need to do npm start There may be other ways of starting it but, all will result in the same. You can read this article on Freecodecamp on deploying on DigitalOcean. You can manipulate it to your localhost. Shouldn't be too different.FCC Tut on Deploying

I used the npm command to create react app, after that my laptop fan started to get louder and when I tried to open any folder it's just not responding. File Explorer is frozen, it said loading the files but it will take forever. I just can't do my work.
I tried to restart File Explorer from task manager and it won't work.
The only way to fix it is to restart my laptop, but it will happen again sometimes even if I don't do anything with the react project. I just need to restart it a couple of times until it back to normal
The first time it happens I wasn't sure because it was the first time I tried to create react and my laptop also had some problems at the time, so I leave the react project for a month.
The second time is yesterday. When I tried to create react app again, File Explorer got freezing.
All this happen after I used the npm command.
Does someone know the answer? I've been trying to learn react and this makes me discouraged. Please help. (Sorry for my poor English)
I think your pc can't handle create react app. It's very heavy and consumes everything in your pc. Probably if you just let it install without using anything it will be ok.
I have a node.js application I have adopted from a more senior developer. I want to deploy it, and I know it will work because he already deployed it several times. I am reading these instructions:
https://galaxy-guide.meteor.com/deploy-quickstart.html
I use windows, as did he.
How does deployment work?
Take these instructions:
Windows If you are using Windows, the commands to deploy are slightly
different. You need to set the environment variable first, then run
the deployment command second (the syntax is the same as everything
you’d put for meteor deploy).
In the case of US East, the commands would be:
$ SET DEPLOY_HOSTNAME=galaxy.meteor.com
$ meteor deploy [hostname]
--settings path-to-settings.json
Am I just supposed to go to the source directory on my laptop and run these commands? What then happens? Is the source uploaded to their server from my laptop and then their magic takes care of the rest?
What about when I want to make a change to the code? Do I just do the same thing, poiting to an existing container and, again, they do the magic?

It is not magic. You basically go to your dev root and enter these commands. Under the hood it builds your app for production (including minification and prod flags for optimization) and once complete opens a connection to the aws infrastructure and pushes the build bundle.
See: https://github.com/meteor/meteor/blob/devel/tools/meteor-services/deploy.js
On the server there will be some install and post install scripts that set up all the environment for you and, if there are no errrors in the process, start your app.
These scripts have if course some automation, depending on your account settings and the commands you have entered.

You will have to rebuild (using the given deploy command) again but Galaxy will take care of the rest.
I have my work computer which is a Windows 10 Pro and my laptop is a Windows 10 Home. Working on the same project on both: push and pull to Git. Learning React through Udemy. Both computers using Chrome. Both using Bash on Ubuntu on Windows with latest updates. Both using ConEmu for the console. Both npm -v = 3.10.10. Both node -v = 6.11.2. Hardware is different obviously, but not sure that is relevant and worth listing.
Anyway, this starter project I am playing around with, when I make changes to it and npm start is running, you can see activity in the console, hit refresh in the browser, and any changes made will be reflected.
On the laptop, this process does not work. Make change, save, no activity in console, refresh in browser does not reflect the changes. Have to restart npm start for changes to be reflected. A little irritating to say the least.
Anyway idea what might cause this? Really haven't come across anything in my Googling efforts.
If you are using npm in WSL2.0 for development, please refer the last point in this-
https://create-react-app.dev/docs/troubleshooting/#npm-start-doesnt-detect-changes
While WSL1.0 doesn't use a VM, WSL2.0 does use a lightweight VM, so adding
CHOKIDAR_USEPOLLING=true
in a .env file in the project directory fixed the problem.
On a sidenote, you might wanna take a look at this
Client side
To ensure client side changes aren't being cached, you can open devtools > Network, and check "Disable cache". After enabling this, you won't have anything in the cache as long as devtools is open.
Alternatively, you can use incognito / private browsing mode to prevent the cache from holding on to things.
Server side
I'm sure you've realized that it's a pain to restart your server every time you want to see your code update. There are several tools that will detect file changes and handle restarting the server automatically.

Nodemon
Forever
I just add file .env and inside FAST_REFRESH=false.
For me, working in Windows, WSL2 caused this not to work. Running npm start in Command Prompt, not WSL solved this issue for me.
I am trying to get a node.js application working on a CI server (Team City). I have a build step which goes like this...
npm start "path/to/my/app"
And it works however the build step hangs because the console will not shut down (it can't because it needs to stay open to run the server). So what can I do to get Team City to kick off the command line without staying open?
You are facing a more general problem of running node.js as a background service (the one that does not hold the console etc.)
Common solution to this is to use Forever CLI tool
I have a web-site that needs to be up all the time. I also, of course, need to do new releases. Each page tends to be very long-lived, with lots of JavaScript doing AJAX calls to the server.
What I do is build a new WAR file and put it in Tomcat's webapps directory, which ends up looking like this:
20110701-7f077d 20110711-aa8db4 20110715-6f4a12
20110701-7f077d.war 20110711-aa8db4.war 20110715-6f4a12.war live
The war file is named after the date of its release and the first few characters of its GIT commit-id, just so I can keep track of everything. Tomcat automatically unpacks the war file into a directory of the same name. The live directly just contains a file giving the name of the "live" version.
This way, each user can continue using the version of the back-end that works with the version of the front-end that he has loaded into his browser. And obviously, version upgrade and reversion is painless.
Now, I'm switching to node.js and I want to do the same thing. I am reliably informed that node.js doesn't support independent applications in one instance. So, what to do?
The only thing I can thing of is to designate n slots (where n is some small number like 10 or 100), and each slot corresponds to a port (i.e., slot 1 is 8001 and so on), put Apache in front of several node.js instances, each representing a slot, and Apache would use mod_proxy or mod_redirect to proxy requests like '/slot01' to port 8081. "live" would point to the current slot.
This would be clumsy and error prone and require an otherwise useless Apache instance and most of all I cannot believe that node.js doesn't have a good solution to what seems like a near-universal problem.
You can use node-http-proxy and write some code to monitor your 'deployment directory' for new versions and when such versions are found you can start the corresponding script and proxy it under the directory name (to make myself clear if you find a new directory 'version-11-today' your parent node-http-proxy script could start the new script assigning it a port passed as a parameter and then proxy to the new app under the path '/version-11-today').
A similar solution could be done with nginx only in this case you could write a script to monitory the deployment directory and generate some new nginx configuration when new apps are found.
If you are afraid you might run out of ports I believe both node.js and nginx can run on and proxy unix sockets besides inet sockets.
An advantage of the above is that each app runs in its own process protecting the other apps from crashes and enabling individual app restarts.
A third solution if you are not afraid some bug will crash your app is to have a parent script that loads all the app versions in the same process and maps them under different paths depending on the directory they were found in. You can still restart your server without downtime such as in this example http://codegremlins.com/28/Graceful-restart-without-downtime
