I have a little web site working with Node.js, and I need to do some tuning for mobiles.
For this I would like to access the HTTP_USER_AGENT. How can I do that?
I have read a few things on the net, but didn't come to a working solution at this point.
One of the thing I went through is this https://www.npmjs.com/package/useragent.
But as soon as I start, adding this to my code:
var useragent = require('useragent');
I get this error when looking at the site:
Application error
An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details.
The log says:
Error: Cannot find module 'useragent'
I must obviously not be doing the right thing or doing it wrong.
Any suggestion will be much appreciated.
Did you installed your package first ?
npm install --save useragent

I'm Having an issue that ruins my entire development plans, And I don't think I'm even the problem!
There is an headless CMS program (open source) called Strapi, If you know the program then good, If not, Your more than welcome to try and tell me if you can help me with this problem.
I'm having trouble creating a Strapi app in VSCode.
The error that I'm receiving is:
You are running Node.js 18.4.0
Strapi requires Node.js >=14.19.1 <=16.x.x
Please make sure to use the right version of Node.
But, The fault isn't on me, I have 16.17.0 version of node installed, and without a trace of the 18.4 version specified on the error code.
I tried uninstalling node, Changing the dependencies in the launch.json file, Nothing worked!
So I Found the solution, the problem was with the version, the recommended 16.17.0 version of node not working with strapi, the 16.15.0 works actually.
This is my first post so my apologies if I leave out some important details that will make it easier to answer the question.
As I was working on my project for my app development class I stumbled upon an error that I cannot fix/figure out what's causing it. I did not mess with any of the node modules and the app was working perfectly fine before the error message.

I have attempted to clear the cache, re install and update some of the packages that I needed for this project, and looked for any errors within the code of my project. No luck after 2 hours of attempts.
Are there any recommendations of that I need to do to fix this? Should I start the project from scratch again?
Thank you all!
Have you tried cd ios && pod install? Also, upload your package.json file
As the error suggests react-navigation-drawer is trying to find a component which doesn't exist. Implying your versions are out of sync.
I was able resolve this issue by upgrading react-navigation#4.0.0.
I wanna start off by saying, I am a complete beginner, so I may have difficulty understanding any answers / terms you may mention.
I'm currently trying to make a web server using 'xampp' from following these youtube tutorials: https://youtu.be/XhLAB1wwzNk
I'm trying to require the 'ws' node module on an Index.js file. I'm given an error:
Uncaught ReferenceError: require is not defined at Index.js:1
I'm not sure how I can get the require module working on my web server.
I've tried installing 'require' by running npm i require and I've also ran npm init to see if it'd do anything. Any help would be appreciated greatly
I've found a way around this, The problem I think was the fact that I was running a php server as oppose to a node.js server as #charlietfl said. So I went and set up a web socket server running off node instead of xampp. It works fine locally.
If anyone has any better suggestions, please feel free to post them.
I've made a react project that uses nodejs, graphql, apollo, express, and mongo DB.
I'm struggling to get it deployed through Heroku.
first, when I deployed it, it failed and said I needed to add a build pack. I've gone through and gotten an idea of what buildpacks are. However, I'm more vague on if I need multiple buildpacks for my application. So I've added both a nodejs buildpack and a create-react-app buildpack. This is the furthest I've reached as it deploys with a 404 error.
One thing to note is that that the nodejs buildpack requires a package.json file in the root folder, though mine were both in my client and server folders. Not sure if I structured it wrong? So I went ahead and npm init in the root folder to create a package.json not knowing if that's an adequate solution.
I've checked the Heroku logs and getting a few errors it seems:
herokulogs
I've also read somewhere about maybe needing a profile? which is not something I entirely understand yet.
As you can tell, I'm new to this and still learning a lot. I'm hoping someone can point me in the right direction as I'd like to see this thing through. Please let me know if you'd like to have access to my codebase.
Thanks
It seems, that npm start throws that error. How did you defined it in your package.json and can you execute it on your local machine?
Have you read the documentation for the Node.js Buildpack?
I'm assuming that you are using one heroku server for both front-end and back-end.
If so, they must be separate.
When trying to build my meteor app using commands:
meteor build ~/pesCloneBuild --server localhost:3000
I get the below error message:
Can anyone kindly guide me on how to resolve this issue?
Looking forward to your response.
It seems like your .meteor/platforms file contains a merge conflict (as suggested by #Philipp). Open it in an editor and make sure it only contains valid platform names. Here is an example:
> cat .meteor/platforms
browser
server
To learn more about this file, see https://guide.meteor.com/mobile.html#adding-platforms for an example of how it is used.
