Setup OGProxy for use in NodeBB

[DownPW]

Hi @phenomlab

it seem virtualmin doesn’t add http2 directive on nginx configuration like you said on tutorial :

Should I add it?
what does it bring?

[phenomlab]

@DownPW it does, but you have to enable it.
Vitrualmin/Server Configuration/Website Options

A fairly concise explanation of http2 and it’s benefits can be found here.

Note, that you will also need this additional block of CSS

.card.card-wrapper {
     background: none;
     width: 450px;
}
 @media (max-width: 767px) {
     .card.card-wrapper {
         background: none;
         width: 100%;
    }
}
 

The original post instructions have been updated

[cagatay]

[DownPW]

you just need to copy the code from the below

And, of course, replace these two values with your own that you already have

var proxy = "FULL_FQDN_OF_YOUR_OGPROXY_HERE";
var apiKey = "YOUR_API_KEY_HERE";

And add new css block code to ACP/custom CSS

@cagatay @DownPW it’s not critical - it only addresses a cosmetic bug so if you haven’t really noticed then it’s not urgent

result with latest code @phenomlab :

My css :

*----------------------------------------------------------------------------*/
/*------------------        nodebb-plugin-OGPROXY       ----------------------*/
/*----------------------------------------------------------------------------*/
 
/* Desktop */
 
/* Iframe */
.card img.card-favicon {
    max-width: 21px;
    max-height: 21px;
    margin-right: 10px;
}
h4.card-site-title {
    color: var(--bs-body-color);
    text-transform: capitalize;
}
.card.card-preview {
    margin: 20px 0 20px 0;
    width: 50%;
}
[component="chat/message"] .card.card-preview {
    margin: 20px 0 20px 0;
    width: 30%;
}
.card.card-preview img:not(.card-favicon) {
    object-fit: cover;

    font-size: 120%;
    color: var(--bs-body-color);

    }
    
    .card.card-preview {
    margin: 20px 0 20px 0;
    width: 100%;

}

maybe you should put the css code in github

[phenomlab]

Thanks. I’ve just seen another bug on mobile because I didn’t add the mobile class. I’ll do it tomorrow and update the code

[DownPW]

@phenomlab

fixed

with this code (add no border and change width) :

.card.card-wrapper {
    background: none;
    border: none;
    /* width: 450px; */
    width: 100%;
}

All the code fixed for Desktop & Smartphone and adding Effect hover Iframe :

.card.card-wrapper {

    /* width: 450px; */
    width: 100%;
}
[component="chat/message"] .card.card-preview {
    margin: 20px 0 20px 0;

  }
  .card-preview p.card-text {

It’s basically this line - replace what you already have in your JS functions with this one.

[cagatay]

@phenomlab i think did it

[crazycells]

hi @phenomlab , what would be the difference between running this on server side (as link-preview plugin) or on client side (as ogproxy) in layman’s terms?

[phenomlab]

@crazycells In laymen terms, it means that there is zero load on the server because all rendering of website previews is handled client side. This makes it more performant on budget hosts because the processing is handled by the visiting web browser.

All sessions are also cached meaning it has superior speed.

[crazycells]

@phenomlab are they cached for each user separately?

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

@crazycells said in Setup OGProxy for use in NodeBB:

No. It’s a shared cache

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