    @veronikya it might flicker on load, yes, and that’s normal. It’s because the CSS and JS are loaded before the custom elements, but it shouldn’t be too bad on reasonable links.

    It shouldn’t flicker at all navigating through the site though as the CSS and JS are already loaded.

    I’m going to be adding some new posts to the labs category, and will use this going forward when writing code that could easily be adopted by others (a great example is the OGProxy, which I will move here).

    If you have any ideas of would like a walkthrough of how to set something up, then this is the place it should go.

    @crazycells said in Setup OGProxy for use in NodeBB:

    are they cached for each user separately?

    No. It’s a shared cache

    additionally, this is also handling youtube videos etc, right?

    No. This is handled by nodebb-plugin-ns-embed

    For anyone else coming here and is struggling to get pm2 to work with Umami (as I did - it started, but never seemed to work after a reboot which is pretty useless), you can use the below. Obviously, change the parts noted inside the [brackets]. Follow the below instructions:

    Instructions

    Open a terminal and create a new systemd service file:

    sudo nano /etc/systemd/system/umami.service

    Add the following content to the file:

    [Unit] Description=Umami Analytics Server After=network.target [Service] Type=simple User=[umami user] WorkingDirectory=[path to umami] ExecStart=/usr/local/bin/node [path to umami]/node_modules/.bin/next start Restart=on-failure [Install] WantedBy=multi-user.target

    Replace [umami user] with the username of the user that should run the Umami service, and [path to umami] with the actual path to your Umami installation.

    Save the file and exit the editor.

    Reload the systemd manager configuration:

    sudo systemctl daemon-reload

    Enable the Umami service to start on boot:

    sudo systemctl enable umami.service

    Start the Umami service:

    sudo systemctl start umami.service

    You can check the status of the service with:

    sudo systemctl status umami.service

    This systemd service file will ensure that Umami starts automatically when the system boots, and it will restart the service if it fails. Remember to adjust the WorkingDirectory and ExecStart paths according to where Umami is installed on your system, and ensure that Node.js is installed and accessible at /usr/bin/node (or adjust the path to Node.js as necessary).

    @crazycells yeah, I’ve noticed that as well. What is it with buzzwords? All they signify to me is that you can “talk the talk” but not “walk the walk”. Anyone can read something on the internet, and after a while, probably recite it word for word, but do they truly understand it?

    I interviewed a guy once who certainly knew buzzwords like the back of his hand, but failed a technical test miserably.

    One other thing I forgot to mention here is that you’ll need mailutils installed on your server for the mail option to work 🙂
