adding some console.log to Nodebb

Solved Customisation

  • I’m trying some code small addition to NodeBB.
    for debugging purposed where do any outputs from console.log() go?

    Usually, when I run my own stand-alone node code it ‘hangs the screen’ until Ctrl-X out of it, hence you can see console.logs
    But as nodeBB runs as a service in the background, you dont see console.log output on the screen

    @eeeee output from console.log will be in the console tab of the browser when your press F12 to access the developer tools.

    oh, surely only javascript console.log goes to front end, Im meaning using console.log in server side node code.
    What I want is a note to myself on server, not viewable front end.
    for example Ive added some code which doesnt work, and I want to log (somewhere)
    “Reached this code”
    x=10
    etc
    So I want to console log to a server side file I can go and read to help me debug.
    Is there a nodebb log already in use I can write to?
    I tried making my own txt file as using fs.writeFile and that did not work, but thinking some built in console.log command would be simpler

    @eeeee if you’re using the console, you could try

    node app.js > app.log 2>&1

    This would redirect stdout to a file named app.log and redirect stderr to stdout.

    I’m not sure about standard logging under NodeBB, but there is an error log located at logs/error.log.

    Failing that, you could always stop the NodeBB service then use ./nodebb dev from the console which would then provide debug output.

    @cagatay The most reliable way to upgrade Node.js on Ubuntu depends on how you originally installed it. Method 1: Using NVM (Recommended) If you already use Node Version Manager (NVM), upgrading is simple. NVM allows you to keep both versions and switch between them if needed. Install Node 22: nvm install 22 Switch to Node 22: nvm use 22 Set it as your default: nvm alias default 22 Verify the change: node -v Method 2: Using NodeSource (PPA) If you installed Node.js via apt using the NodeSource repository, you need to update the repository script to point to the new version. Remove the old NodeSource list (optional but cleaner): sudo rm /etc/apt/sources.list.d/nodesource.list Download and run the NodeSource setup script for Node 22: curl -fsSL [https://deb.nodesource.com/setup_22.x](https://deb.nodesource.com/setup_22.x) | sudo -E bash - Install/Upgrade Node.js: sudo apt-get install -y nodejs Verify the installation: node -v Method 3: Using the ‘n’ Package If you have npm installed, you can use the n interactive manager. Clear the npm cache: sudo npm cache clean -f Install the ‘n’ helper: sudo npm install -g n Install Node 22: sudo n 22 Update your shell: hash -r Troubleshooting Permission Denied: If you see permission errors using Method 2 or 3, ensure you are using sudo. Path Issues: If node -v still shows version 20 after upgrading via NVM, restart your terminal or run source ~/.bashrc. Conflicts: Avoid mixing these methods. If you switch from apt to nvm, it is best to sudo apt remove nodejs first to avoid path conflicts.

    @Panda it will use SMTP. In all cases, I never use any plugin to send email. I’ll always send it raw.

    @Panda as, yes, now I understand and that makes 100% sense. It means those who get down voted can still have an opinion and use common services. And yes, you’re right. Rather than down vote, just ignore if you don’t agree.

    @DownPW the ‘js’ code for the banner takes the time from the client, so what it displays really depends on the regional settings for the operating system. I’ve not seen this issue myself but would like to see some examples of screenshots if possible.
