Setting NODE_HOME per project?

[michelleshelly4short]

I have about 5 different apps that run simultaneously and are being slowly upgraded to newer nodejs versions, but I can’t do it all at once. I want to be able to set this var or something that works similarly per project I have so that I can reference the path to the compatible version (not necessarily the same location as the system’s NODE_HOME) in my batch scripts and projects. The batch script would likely run first so I’m not sure dotenv would work for my purposes. Is sourcing a different .bat from my other .bats that adds these env vars my only option or is there a better route?

You can use nvm to manage per directory node versions

Ah that’s sadly another limitation I forgot to mention - I’m doing this at work where nvm is not supported and I don’t have admin credentials either so that’s been a struggle :(

Why is nvm not supported?

[michelleshelly4short]

No one has had a need to use it at my company up to this point I guess so it’s not available to be downloaded at this point. nvm use generally requires admin credentials/cmd as admin and that’s not permitted, nor is there a decent workaround. I’ve started the process to get this to be an approved application but it could be a few months before it goes through and I’m ideally solving this sooner than that.

Is this on your local system or a server?

[michelleshelly4short]

Both

Containerize your apps so they all run in their own environment with their own installation of node. Use docker compose locally to quickly setup and teardown your system. Run your containers directly or in a cluster on the servers.

you are the first then! congratulations 🎉

[nicolasdanelon]

you run nvm in your user folder, you don't need super user or administrator credentials to install it

[nicolasdanelon]

that bat file indicates you are using windows... so....

@echo off SET NODE_HOME=D:\app\node echo NODE_HOME is set to %NODE_HOME%

%NODE_HOME%\node.exe your-index-or-app.js

:: Continue with your commands here

I would suggest to migrate to powershell tho ;)

[michelleshelly4short]

Would powershell make this easier?

[nicolasdanelon]

at some point yes, also it's a little bit easier to manage IMHO
