# Installing BareRTC
This document will explain how to download and install BareRTC on your own web server.
At this time, BareRTC is not released as a versioned pre-built archive, but as source code. This may change in the future but for now you'll need to git clone or download the source code and compile it, all of which should be easy to do on a Linux or macOS server.
- [Installing BareRTC](#installing-barertc)
- [Requirements \& Dependencies](#requirements--dependencies)
- [Installation](#installation)
- [Deploying to Production](#deploying-to-production)
- [Developing This App](#developing-this-app)
- [License](#license)
## Requirements & Dependencies
To run BareRTC on your own website, you will generally need:
* A dedicated server or <abbr title="Virtual Private Server">VPS</abbr> for your web hosting, e.g. with root access to the console to be able to install and configure software.
* Any Linux distribution or a macOS server will work. You may be able to use a Windows server but this is out of scope for this document and you're on your own there.
* The BareRTC server is written in pure Go so any platform that the Go language can compile for should work.
* Note: if you don't have access to manage your server (e.g. you are on a shared web hosting plan with only FTP upload access), you **will not** be able to run BareRTC.
* Recommended: a reverse proxy server like NGINX.
Your server may need programming languages for Go and JavaScript (node.js) in order to compile BareRTC and build its front-end javascript app.
```bash
# Debian or Ubuntu
sudo apt update
sudo apt install golang nodejs npm
# Fedora
sudo dnf install golang nodejs npm
# Mac OS (with homebrew, https://brew.sh)
brew install golang nodejs npm
```
## Installation
The recommended method is to use **git** to download a clone of the source code repository. This way you can update the app by running a `git pull` command to get the latest source.
```bash
# Clone the git repository and change
git clone https://git.kirsle.net/apps/BareRTC
cd BareRTC/
# Compile the front-end javascript single page app
npm install
npm run build
# Compile the back-end Go app to ./BareRTC
make build
# Or immediately run the app from Go source code now
# Listens on http://localhost:9000
make run
# Command line interface to run the binary:
./BareRTC -address :9000 -debug
```
You can also download the repository as a ZIP file or tarball, though updating the code for future versions of BareRTC is a more manual process then.
* ZIP download: https://git.kirsle.net/apps/BareRTC/archive/master.zip
* Tarball: https://git.kirsle.net/apps/BareRTC/archive/master.tar.gz
## Deploying to Production
It is recommended to use a reverse proxy such as nginx in front of this app. You will need to configure nginx to forward WebSocket related headers:
```nginx
server {
server_name chat.example.com;
listen 443 ssl http2;
listen [::]:443 ssl http2;
ssl_certificate /etc/letsencrypt/live/chat.example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/chat.example.com/privkey.pem;
# Proxy pass to BareRTC.
location / {
proxy_pass http://127.0.0.1:9000;
# WebSocket headers to forward along.
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "Upgrade";
proxy_set_header Host $host;
}
}
```
You can run the BareRTC app itself using any service supervisor you like. I use [Supervisor](http://supervisord.org/introduction.html) and you can configure BareRTC like so:
```ini
# /etc/supervisor/conf.d/barertc.conf
[program:barertc]
command = /home/user/git/BareRTC/BareRTC -address 127.0.0.1:9000
directory = /home/user/git/BareRTC
user = user
```
Then `sudo supervisorctl reread && sudo supervisorctl add barertc` to start the app.
## Developing This App
In local development you'll probably run two processes in your terminal: one to `npm run watch` the Vue.js app and the other to run the Go server.
Building and running the front-end app:
```bash
# Install dependencies
npm install
# Build the front-end
npm run build
# Run the front-end in watch mode for local dev
npm run watch
```
And `make run` to run the Go server.

## Cut
Sent by: Server.
The server tells the client to turn off their camera. This is done in response to a `/cut` command being sent by an admin user: to remotely cause another user on chat to turn off their camera and stop broadcasting.

It is very much in the style of the old-school Flash based webcam chat rooms of the early 2000's: a multi-user chat room with DMs and _some_ users may broadcast video and others may watch multiple video feeds in an asynchronous manner. I thought that this should be such an obvious free and open source app that should exist, but it did not and so I had to write it myself.

* [x] /op and /deop users (give temporary mod control)
* [x] /help to get in-chat help for moderator commands
The BareRTC project also includes a [Chatbot implementation](docs/Chatbot.md) so you can provide an official chatbot for fun & games & to auto moderate your chat room!
@ -92,27 +91,7 @@ See [Authentication](docs/Authentication.md) for more information.
If you authenticate an Op user via JWT they can enter IRC-style chat commands to moderate the server. Current commands include:
* `/kick <username>` to disconnect a user's chat session.
* `/ban <username> [hours]` to ban a user from chat (temporary - time-based or until the next server reboot, default 24 hours)
* `/nsfw <username>` to tag a user's video feed as NSFW (if your settings.toml has PermitNSFW enabled).
* `/cut <username>` to 'cut' their webcam feed (instruct their web page to turn off their camera automatically)
There are easy buttons for the above commonly used actions in a user's pop-up "profile card" on the chat room.
Additional operator commands include:
* `/unban <username>` to lift the ban on a user.
* `/bans` to list all of the currently banned users.
* `/op <username>` to grant operator controls to a user (temporary, until they log off)
* `/deop <username>` to remove operator controls
* `/unmute-all` removes the mute flag on all users for the current operator (intended especially for the [Chatbot](docs/Chatbot.md) so it can still moderate public chat messages from users who have blocked it from your main website).
And there are some advanced commands intended for the server system administrator (these can be 'dangerous' and disruptive to users in the chat room):
* `/shutdown` will shut down the chat server (and hopefully, reboot it if your process supervisor is configured as such)
* `/reconfigure` will reload the server config file without needing to reboot.
* `/kickall` will kick ALL users from the room, with a message asking them to refresh the page (useful to deploy backwards-incompatible server updates where the new front-end is required to be loaded).
In case your operators forget, the `/help` command will list the common moderator commands and `/help-advanced` will list the more advanced/dangerous ones. **Note:** there is only one level of admin rights currently, so it will be a matter of policy to instruct your moderators not to play with the advanced commands.

@ -110,202 +110,3 @@ The JSON response to this endpoint may look like:
"Error": "if error, or this key is omitted if OK"
}
```
## POST /api/block/now
Your website can tell BareRTC to put a block between users "now." For
example, if a user on your main website adds a block on another user,
and one or both of them are presently logged into the chat room, BareRTC
can begin enforcing the block immediately so both users will disappear
from each other's view and no longer get one another's messages.
The request body payload looks like:
```json
{
"APIKey": "from your settings.toml",
"Usernames": [ "alice", "bob" ]
}
```
The pair of usernames should be the two who are blocking each other, in
any order. This will put in a two-way block between those chatters.
If you provide more than two usernames, the block is put between every
combination of usernames given.
The JSON response to this endpoint may look like:
```json
{
"OK": true,
"Error": "if error, or this key is omitted if OK"
}
```
## POST /api/disconnect/now
Your website can tell BareRTC to remove a user from the chat room "now"
in case that user is presently online in the chat.
The request body payload looks like:
```json
{
"APIKey": "from your settings.toml",
"Usernames": [ "alice" ],
"Message": "a custom ChatServer message to send them, optional",
"Kick": false,
}
```
The `Message` parameter, if provided, will be sent to that user as a
ChatServer error before they are removed from the room. You can use this
to provide them context as to why they are being kicked. For example:
"You have been logged out of chat because you deactivated your profile on
the main website."
The `Kick` boolean is whether the removal should manifest to other users
in chat as a "kick" (sending a presence message of "has been kicked from
the room!"). By default (false), BareRTC will tell the user to disconnect
and it will manifest as a regular "has left the room" event to other online
chatters.
The JSON response to this endpoint may look like:
```json
{
"OK": true,
"Removed": 1,
"Error": "if error, or this key is omitted if OK"
}
```
The "Removed" field is the count of users actually removed from chat; a zero
means the user was not presently online.
# Ajax Endpoints (User API)
## POST /api/profile
Fetch profile information from your main website about a user in the
chat room.
Note: this API request is done by the BareRTC chat front-end page, as an
ajax request for a current logged-in user. It backs the profile card pop-up
widget in the chat room when a user clicks on another user's profile.
The request body payload looks like:
```json
{
"JWTToken": "the caller's chat jwt token",
"Username": "soandso"
}
```
The JWT token is the current chat user's token. This API only works when
your BareRTC config requires the use of JWT tokens for authorization.
BareRTC will translate the request into the
["Profile Webhook"](Webhooks.md#Profile%20Webhook) to fetch the target
user's profile from your website.
The response JSON given to the chat page from /api/profile looks like:
```json
{
"OK": true,
"Error": "only on error messages",
"ProfileFields": [
{
"Name": "Age",
"Value": "30yo"
},
{
"Name": "Gender",
"Value": "Man"
},
...
]
}
```
## POST /api/message/history
Load prior history in a Direct Message conversation with another party.
Note: this API request is done by the BareRTC chat front-end page, as an
ajax request for a current logged-in user.
The request body payload looks like:
```json
{
"JWTToken": "the caller's chat jwt token",
"Username": "soandso",
"BeforeID": 1234
}
```
The JWT token is the current chat user's token. This API only works when
your BareRTC config requires the use of JWT tokens for authorization.
The "BeforeID" parameter is for pagination, and is optional. By default,
the first page of recent messages are returned. To get the next page, provide
the "BeforeID" which matches the MessageID of the oldest message from that
page. The endpoint will return messages having an ID before this ID.
The response JSON given to the chat page from /api/profile looks like:
```javascript
{
"OK": true,
"Error": "only on error messages",
"Messages": [
{
// Standard BareRTC Messages.
"username": "soandso",
"message": "hello!",
"msgID": 1234,
"timestamp": "2024-01-01 11:22:33"
}
],
"Remaining": 12
}
```
The "Remaining" integer in the result shows how many older messages still
remain to be retrieved, and tells the front-end page that it can request
another page.
## POST /api/message/clear
Clear stored direct message history for a user.
This endpoint can be called by the user themself (using JWT token authorization),
or by your website (using your admin APIKey) so your site can also clear chat
history remotely (e.g., for when your user deleted their account).
The request body payload looks like:
```javascript
{
// when called from the BareRTC frontend for the current user
"JWTToken": "the caller's chat jwt token",
// when called from your website
"APIKey": "your AdminAPIKey from settings.toml",
"Username": "soandso"
}
```
The response JSON given to the chat page looks like:
```javascript
{
"OK": true,
"Error": "only on error messages",
"MessagesErased": 42
}
```

* **ForwardMessage** (bool): whether to repeat the message to the other chatters. If false, the sender will see their own message echo (possibly censored) but other chatters will not get their message at all.
* **ReportMessage** (bool): if true, report the message along with the recent context (previous 10 messages in that conversation) to your website's report webhook (if configured).
* **ChatServerResponse** (str): optional - you can have ChatServer send a message to the sender (in the same channel) after the filter has been run. An empty string will not send a ChatServer message.
## Moderation Rules
This section of the config file allows you to place certain moderation rules on specific users of your chat room. For example: if somebody perpetually needs to be reminded to label their camera as NSFW, you can enforce a moderation rule on that user which _always_ forces their camera to be NSFW.
Settings in the `[[ModerationRule]]` array include:
* **Username** (string): the username on chat to apply the rule to.
* **CameraAlwaysNSFW** (bool): if true, the user's camera is forced to NSFW and they will receive a ChatServer message when they try and remove the flag themselves.
* **NoBroadcast** (bool): if true, the user is not allowed to share their webcam and the server will send them a 'cut' message any time they go live, along with a ChatServer message informing them of this.
* **NoVideo** (bool): if true, the user is not allowed to broadcast their camera OR watch any camera on chat.
* **NoImage** (bool): if true, the user is not allowed to share images or see images shared by others on chat.
### JWT Moderation Rules
Rather than in the server-side settings.toml, you can enable these moderation rules from your website's side as well by including them in the "rules" custom key of your JWT token.
The "rules" key is a string array with short labels representing each of the rules:
| Moderation Rule | JWT "Rules" Value |
|------------------|-------------------|
| CameraAlwaysNSFW | redcam |
| NoBroadcast | nobroadcast |
| NoVideo | novideo |
| NoImage | noimage |
An example JWT token claims object may look like:
```javascript
{
"sub": "username", // Username for chat
"nick": "Display name", // Friendly name
"img": "/static/photos/username.jpg", // user picture URL
"url": "/u/username", // user profile URL
"rules": ["redcam", "noimage"], // moderation rules
}
```
## Direct Message History
You can allow BareRTC to retain temporary DM history for your users so they can remember where they left off with people.
Settings for this include:
* **Enabled** (bool): set to true to log chat DMs history.
* **SQLiteDatabase** (string): the name of the .sqlite DB file to store their DMs in.
* **RetentionDays** (int): how many days of history to record before old chats are erased. Set to zero for no limit.
* **DisclaimerMessage** (string): a custom banner message to show at the top of DM threads. HTML is supported. A good use is to remind your users of your local site rules.
## Logging
This feature can enable logging of public channels and user DMs to text files on disk. It is useful to keep a log of your public channels so you can look back at the context of a reported public chat if you weren't available when it happened, or to selectively log the DMs of specific users to investigate a problematic user.
Settings include:
* **Enabled** (bool): to enable or disable the logging feature.
* **Directory** (string): a folder on disk to save logs into. Public channels will save directly as text files here (e.g. "lobby.txt"), while DMs will create a subfolder for the monitored user.
* **Channels** ([]string): array of public channel IDs to monitor.
* **Usernames** ([]string): array of chat usernames to monitor.

<ol>
<li>
Chat Settings: by clicking on the blue menu button on the top-right corner of the page, the
Display tab has a "Video size" dropdown with some options to change the size of all videos
open on your screen.
First, you need to share your own local webcam first (by clicking on the green "Share webcam"
button at the top of the chat page).
</li>
<li>
On wide screens (such as an iPad in landscape orientation): when you have videos open, look
for the <i class="fa fa-magnifying-glass-plus"></i> <i class="fa fa-magnifying-glass-minus"></i>
buttons in the header just above the video dock. Clicking on these buttons will scale the docked
videos larger or smaller (in similar increments as the Chat Settings dropdown).
Then, you may only be able to view somebody else's camera <strong>IF</strong> they have marked
the setting "When somebody opens my camera, I also open their camera automatically."
</li>
</ul>
</ol>
<p>
If you are on a device with a mouse cursor, such as a desktop or a laptop with a touchpad, there
are a couple of ways to resize individual videos how you see fit:
This is because Apple Safari only supports two-directional video calls, which is in contrast to the
way that BareRTC was designed to work: it is intended to be possible that somebody can start their webcam
and be watched by anybody who wants to tune in, without it always needing to be a two-way video call. But
for Apple Safari browsers, uni-directional video channels are not supported, so iPads and iPhones are only
able to successfully connect to a video <strong>if</strong> that person opts-in to open your video in
return (thus making it a two-way video call).
</p>
<ul>
<li>
When videos are docked in the top of the page, hover your mouse over the bottom-right corner
of a video. It should show a 'resize' cursor, and you can click and drag from the bottom-right
corner to resize the video.
</li>
<li>
Videos can also be "popped out" of the dock at the top of the page. The pop-out button appears
on top of videos, next to the mute audio button. When popped out, you can drag videos anywhere
on the page and you can resize them by dragging from any edge except the top.
</li>
</ul>
<p>
And finally: you can put a video "full screen" too. In the control buttons at the bottom of each
video (beginning with the mute audio button), the one on the right will toggle the video into a
full screen view.
For <i class="fab fa-apple"></i> <strong>macOS users</strong>, it is recommended to use a Chromium or
Firefox browser instead of Safari for the best experience. It is only Safari-based browsers that have
this limitation. Unfortunately, there is no alternative for iPad or iPhone: <em>every</em> web browser on
iOS is based on Safari per Apple's app store guidelines. (Chrome and Firefox on iOS were not allowed to
bring their <em>actual</em> web browser engine to Apple's mobiles).

Troubleshooting

<p>
This section contains some troubleshooting advice for issues commonly experienced in the chat room.
</p>
<h2 id="webcam-troubleshooting">
Webcam Sharing
<a href="#webcam-troubleshooting" class="fa fa-paragraph is-size-6"></a>
</h2>
<h3 id="NotAllowedError">
Permission Denied, or NotAllowedError
<a href="#NotAllowedError" class="fa fa-paragraph is-size-6"></a>
</h3>
<p>
If you see an error message from <strong class="has-text-danger">ChatClient</strong> that says
something like "Webcam error: Permission denied" or a "NotAllowedError," this section is for you.
</p>
<p>
The reason for this error is that your web browser did not grant access to your Camera and Microphone
for the chat room to use. This may be because you accidentally clicked on the "Deny" button when your
browser asked you for permission, or because your web browser <em>itself</em> does not have permission for
these devices on your computer.
</p>
<p>
When you encounter this error, there are two places to look to resolve this:
</p>
<ol>
<li>
In your web browser's settings (e.g. in Google Chrome or Firefox), make sure that you are granting
permission for your Camera and Microphone to the chat room's website ({{.Hostname}}).
</li>
<li>
In your operating system's settings, ensure that your web browser itself has permission to use
your Camera and Microphone. <strong>Notice:</strong> on recent Mac OS and Windows systems, your
web browser might not have permission by default to access these devices!
</li>
</ol>
<p>
Please see the following sections for in-depth guidance on where to look.
</p>
<p>
<strong>Notice:</strong> webcam sharing will require both your Camera <em>and</em> your Microphone
permission - if either one is denied, webcam sharing will fail.
</p>
<h4>1. Check your web browser's permissions for {{.Hostname}}</h4>
<p>
Go into your web browser's settings, to the "Privacy" or "Permissions" section and verify that
<code>{{.Hostname}}</code> has permissions to use your Camera <strong>and</strong> your Microphone.
Or at the very least: make sure that these settings are not set to "Deny" for {{.Hostname}}.
</p>
<p>
For example, on <i class="fab fa-chrome"></i> <strong>Google Chrome:</strong>
</p>
<ul>
<li>Go into your browser Settings -> "Privacy and security"</li>
<li>Click on "Site settings" <small>("Controls what information sites can use and show (location, camera, pop-ups, and more")</small></li>
<li>From here you can check the permissions in two ways:
<ul>
<li>Under the "Recent activity" section, look for {{.Hostname}} or click "View permissions and data stored across sites" to look for it there.</li>
<li>Or: under the "Permissions" section, click into the "Camera" and "Microphone" settings to see the list of sites you've given/denied
permission for, and change {{.Hostname}} to "Allow" or remove {{.Hostname}} from the list of sites.
</li>
</ul>
</li>
</ul>
<p>
Or for example, on <i class="fab fa-firefox"></i> <strong>Mozilla Firefox:</strong>
</p>
<ul>
<li>Go into your browser Settings -> "Privacy & Security"</li>
<li>Scroll down to the "Permissions" section where you see buttons for Camera and Microphone.</li>
<li>Click on the "Settings..." button for Camera and Microphone to see the list of websites you've given/denied permission for.</li>
<li>Find <code>{{.Hostname}}</code> and remove it from the list.</li>
</ul>
<p>
After changing your browser settings, <strong>exit and restart your web browser</strong> and log on to the chat room.
When going on webcam, hopefully your browser should ask you for permission for your webcam and microphone: be sure to
click on "Allow" when prompted.
</p>
<p>
If the change in your web browser's settings doesn't resolve the permission error, then check in your operating system's settings.
</p>
<h4>2. Check in your operating system's settings</h4>
<p>
For example, <strong>if you are on <i class="fab fa-apple"></i> Mac OS:</strong>
</p>
<ul>
<li>Click on the Apple icon in your top menu bar and open "System Settings"</li>
<li>Click on "Privacy &amp; Security"</li>
<li>Look for the Camera and Microphone settings and ensure that they are <strong>allowed</strong> for your web browser.</li>
<li>For more information, try: <a href="https://support.apple.com/guide/mac-help/control-access-to-your-camera-mchlf6d108da/mac">https://support.apple.com/guide/mac-help/control-access-to-your-camera-mchlf6d108da/mac</a></li>
</ul>
<p>
Or for example, <strong>if you are on <i class="fab fa-windows"></i> Windows 10 or Windows 11:</strong>
</p>
<ul>
<li>Click on the Start button > Settings > Privacy & Security > Camera, and make sure Camera access is turned <strong>on.</strong></li>
<li>Make sure that "Let apps access your camera" is also turned on.</li>
<li>Ensure that your web browser (e.g. Google Chrome) has permission to access your camera and microphone.</li>
<li>For more information, try: <a href="https://support.microsoft.com/en-us/windows/manage-app-permissions-for-your-camera-in-windows-87ebc757-1f87-7bbf-84b5-0686afb6ca6b">https://support.microsoft.com/en-us/windows/manage-app-permissions-for-your-camera-in-windows-87ebc757-1f87-7bbf-84b5-0686afb6ca6b</a></li>

<h3 id="other-webcam-errors">
Other Webcam Errors
<a href="#other-webcam-errors" class="fa fa-paragraph is-size-6"></a>
</h3>
<p>
The most common error is a Permission Error as described above, but there are some less common
error messages you may experience. Here is a short list of some of them:
</p>
<ul>
<li>
<strong>AbortError:</strong> e.g. "Starting videoinput failed"
<br><br>
A common cause for this error may be that your webcam device is already in use by a different program,
so that your web browser was not able to open it. Please make sure that you are not running another video
chat program (such as Skype or Zoom) which has your camera active, and try again.
</li>
<li>
<strong>NotFoundError</strong> or <strong>NotReadableError</strong>
<br><br>
This error may indicate that your camera device was not available to your web browser. For example, your
webcam might not be plugged in to USB or you may be missing hardware drivers for it. To begin diagnosing
this problem, check whether <other>other</other> websites or apps are able to use your camera: if none of
them can either, it heavily points toward a hardware or driver error.
</li>
</ul>
<p>
Other possible errors should be uncommon. If this troubleshooting guide has not been helpful, try copying
the error message into a search engine and find information online: all of the text following "Webcam error:"
will be coming from your web browser, so relevant results may be found online. A possible place to start may
be the <a href="https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia">Mozilla documentation for getUserMedia.</a>
</p>
<h3 id="webcam-not-loading">
Other peoples' webcams don't load
<a href="#webcam-not-loading" class="fa fa-paragraph is-size-6"></a>
</h3>
<p>
It may sometimes happen that you clicked to watch somebody else's webcam on chat, and their video doesn't
load. If it only happens with <em>some</em> cameras (but other cameras load correctly), then the problem is
most likely on <em>that person's</em> side and not your own: their camera likely doesn't work for anybody
else who is trying to watch it, either.
</p>
<p>
Webcam sharing on the chat room works by "peer to peer" direct connections between chatters. Usually, this
tends to "just work" for most people, but sometimes your network connection or firewall can get in the way
and prevent a connection from being established.
</p>
<p>
The most common kinds of network conditions that cause problems connecting to webcams include:
</p>
<ul>
<li>
If you are on a heavily firewalled network, such as in a school or workplace.
</li>
<li>
If you are on a cellular network, e.g. from a smartphone or tablet. Some cell phone carriers
add firewalls to their network to prevent direct peer-to-peer connections with mobile devices.
</li>
<li>
If you are using a Virtual Private Network, or VPN: some VPN providers don't forward the kind
of network messages that are needed to establish a peer-to-peer connection.
</li>
</ul>
<p>
For some specific advice:
</p>
<ul>
<li>
If you can not connect to <strong>any</strong> webcam at all (e.g. many people are on webcam but you
can not get <strong>any</strong> of them to work): most likely it is because you are on a firewalled
network, like those listed above. If you are on a cell network, try switching to WiFi; or if you are
using a VPN, try turning off your VPN.
</li>
<li>
If <strong>only one or two webcams</strong> won't open for you, but others on the chat room are working:
the problem is likely not on your end! It is likely that the people whose cameras are not working are
on a firewalled network, and they are likely having worse problems than you are!
</li>
<li>
If somebody's webcam button has a slash \ through it, like <i class="fa fa-video-slash has-text-info"></i>
then it <em>probably</em> means that this person requires <strong>you</strong> to share your webcam first
before you can open theirs. You can click on their camera button to see an exact reason why their camera
has the \ slash through it.
</li>
</ul>
