How about a contest who fixes the most plugins then?

.. well, almost. It's a plugin, after all.

npm install nodebb-plugin-smoothshorts

Features

(README.md)
Once a user opens the browser's context menu upon a topic link, the href value of that link gets replaced with its assigned hash:

This also works on posts (theme-persona; couldn't find post links in theme-lavender).
The now copied address is one of the form https://yourNodeBB.org/ss/HASH. Visiting it will set some logic in motion, finding the associated post or topic and redirecting accordingly:

The original address is restored on any next mousedown event. This way, even if the just hashed and copied link is clicked, the user will be visiting that original, since the event is processed before the browser attempts to follow the link. (Tested in FireFox 38.05 and Chrome 43.0; please let me know if your browser doesn't work!)

Changelog

0.1.0

• Added ACP page.
  • Settings
  • Create missing hashs topics/posts.
• Added modifier key (ctrl, alt or shift) to replace urls.
• Added ability to change domain for short urls.
  (https://prettylongdomain.org/topic/2/slug/ -> https://short.org/ss/hash)

(Hopefully) As requested by @chrismccoy
Thanks for the idea!

nodebb-plugin-expiring-uploads

Hide and expire users uploads.

The name actually only tells half the story. This plugin lets you:

1. Hide uploads of definable filetypes behind a hash/timestamp/filename combination. Uploads are not stored in the standard path (public/uploads). This ensures, that even when the filename is known, it's pretty hard to guess its location.

2. Set an expiration time(range) for those hash/timestamp/filename urls. Every setting > 0 will have uploads handled by this plugin expire.

PLEASE NOTE: Expiration is calculated at request time. If you uploaded a file 7 days ago and now decide to lower the expiration time from 10 to 5 days, this file will be treated as expired.

Installation

1. npm install nodebb-plugin-expiring-uploads

2. Activate the plugin in the ACP.

3. Adjust the settings! Standard expiration time is 0 = uploads never expire.

GitHub | Bugs & Suggestions

Hi!
You probably don't remember me. It's been - what? - 5 years or so. Shortly after we founded the community organization on GitHub.

Yesterday, I received a request that immediately made me think: I've got just the right tool for you; NodeBB!

Coming back to your site really warms my heart. Not only are you guys still alive and kicking, but it's amazing how far you have come.

I'm excited to test drive the mongodb backend. I remember how much I wanted that to happen.

@chrismccoy
Is this, more or less, what you are looking for?
Please consider this an early alpha preview, that will most definetly clutter the * peep * out of your log.

npm i nodebb-plugin-expiring-uploads

I've taken the liberty to replace the md5- with xx-hashs. MD5 is outdated since years and quite verbose (aa1469dd64687462ee30378e14d34105 vs. 6edebbb6).
The outcoming url is of the form:
ht*p://nodebb/uploads/xxhash/CreationTimestamp-in-hex/filename.ext
e.g. ht*p://lsw.local/uploads/705bab4a/14e6b6e49dc/droid-sans-mono.zip

The seed of xxhash is the first part (up to the first - ) of your nodeBB's secret (config.json).

On the HDD, files are stored in /nodeBB/expiring_uploads/ as opposed to /nodeBB/public/uploads/files/, since everything in /public/ could be guessed, as all of its contents seem to be blindly exposed to the clients. Please note, that my lazily hardcoding the / could make this plugin fail on Windows. I'll change that, or at least check whether the NodeBB core takes care of it.

The created links are routed, but you can't actually download the file, yet.

The plugin hook (filter:uploadFile) is pretty needy - or powerful; depending on your point of view. Anyway, it breaks out of (returns from) the core function, handling uploads, as early as it can get. Meaning, that the plugin has to handle everything like allowed filetypes, -sizes and such. I assume, that you e.g. don't want to have uploaded pictures expire. It's in there, but only rudimentarily, for now. That's why I haven't started the ACP part of it, yet.

In the end the plugin will surely have an option to choose, but for starters: What's your preference, the least setup effort for you? Would you rather define filetypes which should be expiring or those who should not?
Another aproach would be to add a second "Expiring Upload" button to the composer. This way the built-in button would follow the general setup (e.g. allowed filetypes images) and the added button would only accept .zip, .gz, .pdf, what have you.

Don't give up so easily

Yes! Yes! Yes!

JavaScript is a prototypal language, which makes it a bit confusing, but very powerful. You can structure your programs in various ways. I'm only gonna go into how it's (mostly) done in nodeJS:

Although you define objects with members, it is uncommon to actually create instances of those objects. JS has a new keyword that allows you to do that, but there it gets messy with this and what it means. Sometimes this points to an object, sometimes a function - it all depends on where you use it and who called what. You should read up on 'function scope' and 'closure', in case you're interested. I myself still like to use it. But anyway, most code you will encounter treats objects as static. Also, function parameters are passed by value rather than by reference (you may know this from C as passing a variable vs. passing a pointer). Let's have a look:

var aNumberVariable = 50;

myMethod = function(functionsNumberVariable) {
    functionsNumberVariable = 100;
    console.log(functionsNumberVariable);
};

myMethod(aNumberVariable);
console.log(aNumberVariable);

When you execute this snippet, the output will read 100 and then 50.

Your browser's console is awesome for fiddling! I use chrome.

Here you can see, that aNumberVariable is assigned 50, myMethod defined and then called. The parameter is passed to the function, where only its value is received, and put into a newly created variable functionsNumberVariable. This then is set to 100 and written to the console. The function call (myMethod()) is done synchronously, so everything following 'waits' for the function to finish/return. It does so with no value (aka undefined), but the console ignores that. Then the last line is executed, showing that aNumberVariable's value is still 50. (The showing undefined in the picture is actually not from anywhere in my code. I think that is the result of a function, the console's VM wraps your statements in. Once again the scope thingy.)

But this also means, that once myMethod is through doing its thing, you have no way to access functionsNumberVariable anymore (before mentioned closure or function scope). Even worse, it's a candidate to be gobbled up by the garbage collector in one of its next runs. Now, you could, of course, easily just return its value, but this is where nodeJS's magic of asynchronicity gets in between.

Everything below would have to wait for your function to return, so a read from a database or from a network resource could easily block your process for a lengthy amount of time - not so good.
Fortunately, JavaScript is capable of passing functions as parameters. . This - we're almost there - is the callback (in our case here; you can do heaps of other neat things with it). You basically pass the next step in your chain of processing as this function, passing it the values which you otherwise would have returned. I fail to come up with a quick and easy code example to run, right now. So I'll draw it in a diagram:

At this point you'd be perfectly right to say: "Well, nice story. But there's also an invisible return in queryDatabase which the program has to wait for.". Yes, it is. That's why I painted its declaration yellowish. Your JavaScript runs also in nodeJS on a single thread, but under the hood, when V8 (JS engine) passes such calls to the I/O layer it utilises multi-threading. This game of passing callbacks is played along the chain, until V8 'queries' some system I/O function. There it is split off into another thread, from where (on the return path, if you will) the callbacks are called one after another. The actual functions returns are done as soon V8 has branched off this new thread. I'm not 100% sure about this last part, though. I urge everyone who knows more about this to correct me!

By the way: Every function comes with several 'invisible' variables set. One of which is arguments. That's an array of all parameters passed to the function. Disregarding the declarations (function(var1, var2)) you did. So even when you define your function as myMethod = function(), arguments is available and filled with everything that has been passed in the call. Great for exploring!

I'm not sure if I understood you correctly, but I think you want to use the PluginSocket (socket.io) for this:

Server:

Use pgrep/pkill!

kill -s USR1 $(fgrep -f "app.js")

or even shorter with pkill

pkill -USR1 -f "app.js"

Substitute -USR1 with -SIGHUP and you got yourself a quick and easy build-tool command to restart NodeBB, when changing files.

0.1.0 is here!

Added ACP page, hashing old topics/posts and different domain for short urls.
As well as the ability to use a modifier key for replacing urls. I highly suggest to use this feature, since the context menu offers more options than just copying links.

Here's a preview of the ACP page:

Well, in terms of losing your userbase one after another, once they figure out that your site allows people to spread their malware, of course.

Seriously though:
As long as you don't explicitly execute uploaded files on you server, I don't think so. Haven't seen any code that does it automatically. But then again: Never say never. There's always a chance that someone figures a way to do it.
Apart from that always present risk, I'd give it a "No, it can not."

Furthermore, this depends on which OS you are running your site on. Linux systems are somewhat safe due to the simple fact, that there just is little malware for that OS. More importantly is it a matter of proper configuration. In server-land (Linux/Windows alike, though Linux again clearly has the advantage) you should always have your deamons (services) run with their own user. Giving them only the priviliges (access to files, network interfaces, what not...) they really need to do their thing. This way, worst case, your site itself would be harmed, but without having your whole machine compromised, so replaying a backup would solve the problem rather easily.

And there we go.

Thanks @rbeer for the information about nodejs versions. I did not see the indicator that you did obviously.

Very nice! Glad to see it working now.
And, don't you worry! I was tearing my hair out for about an hour, when I stumbled upon that error some weeks ago.

@xen
Binding a port through your ssh connection is actually quite simple.
(The following assumes that you are using the OpenSSH client on GNU/Linux)

tl;dr:
https://youtu.be/vC7Smc67gPg

1. Start the SSH client with ssh [email protected] -L 7000:localhost:6379
   So basically like you would normally do, appending -L ... with the syntax:
   • local_port:interface_on_remote:remote_port (ssh manpage)
2. You should have an interactive session to your remote, prompt and all or whatever your setup resolves into when logging in over SSH. Again, business as usual is expected here.
3. Now comes the good part: Since you tunneled your local port 7000 to the remotes localhost interface on (redis-) port 6379, you can create a new connection in Redis Desktop Manager, ignoring the SSH tab in the "New Connection" dialog and simply connecting to localhost:7000.

That might be true. I am not familiar with CentOS and its package management.

Replacing the install instructions in question with nodesource (https://github.com/nodesource/distributions/tree/master/), might be a good idea. I know e.g. that Debian also has 0.10.x in its repos.

All your logs and screenshots show a nodejs version 0.10.x. That's heavily outdated. Which manifests itself fataly in

../node_modules/nan/nan.h:328:47: error: ‘REPLACE_INVALID_UTF8’ is not a member of ‘v8::String’
   static const unsigned kReplaceInvalidUtf8 = v8::String::REPLACE_INVALID_UTF8;

i.e. a module, that needs compilation, can't find a member (REPLACE_INVALID_UTF8) of the String class in v8. It must have been introduced later. Upgrading to 0.12.x at least should solve this problem.

I'm curious about the contents of two files:

@wellenreiter

Hi @Pilvinen

I hope you didn't purge redis, already. That could have deleted the log file, as well.

I'm curious about the contents of two files:

• /var/log/redis/redis-server.log
• /path/to/nodebb/log/nodebb.log

Like all the others, I suspect redis itself to be the source of failure here. NodeBB uses the DB's flush (wipe all data) only in its tests; even there on a test-databse you'd have to set up explicitly.

Views shouldn't be used for measuring popularity, whatsoever. At least as it is now. You can keep spamming the refresh button or even write a tiny script to request a topic. There is really no checks in place. It is too easily manipulated.

If that was changed to #views/#users, then it might become a good tool for measuring e.g. how many users have been reached with an announcement topic.

-1 for videos with robot voice, btw.

I don't know, sorry.
Actually, because I don't know anything about IE, at all. When FF gained users and Chrome came into play, I decided to abandon IE all together. Now, I know this looks like a stupid move, but around the same time also mobile devices gained market shares. Forseeing that those would be the future anyway, I diverted my focus onto them rather any longer hassling with IE.
