## Requirements
This document describes how to do a full deployment of Firefox Send on your own Linux server. You will need:

* A working (and ideally somewhat recent) installation of NodeJS and NPM
* GIT
* An Apache webserver
* Optionally telnet, to be able to quickly check your installation

For Debian/Ubuntu systems this probably just means something like this:

* apt install git apache2 nodejs npm telnet

## Building
* We assume an already configured virtual-host on your webserver with an existing empty htdocs folder
* First, remove that htdocs folder - we will replace it with Firefox Send's version now
* git clone https://github.com/mozilla/send.git htdocs
* Make now sure you are NOT root but rather the user your webserver is serving files under (e.g. "su www-data" or whoever the owner of your htdocs folder is)
* npm install
* npm run build

## Running
To have a permanently running version of Firefox Send as a background process:

* Create a file "run.sh" with:
```
#!/bin/bash
nohup su www-data -c "npm run prod" 2>/dev/null &
```
* chmod +x run.sh
* ./run.sh

Now the Firefox Send backend should be running on port 1443. You can check with:
* telnet localhost 1443

## Reverse Proxy
Of course, we don't want to expose the service on port 1443. Instead we want our normal webserver to forward all requests to Firefox send ("Reverse proxy").

# Apache webserver

* a2enmod proxy
* a2enmod proxy_http
* a2enmod proxy_wstunnel

In your Apache virtual host configuration file, insert this:

```
    # Enable rewrite engine
    RewriteEngine on

    # Make sure the original domain name is forwarded to Send
    # Otherwise the generated URLs will be wrong
    ProxyPreserveHost on

    # Make sure the generated URL is https://
    RequestHeader set X-Forwarded-Proto https

    # If it's a normal file (e.g. PNG, CSS) just return it
    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule .* - [L]

    # If it's a websocket connection, redirect it to a Send WS connection
    RewriteCond %{HTTP:Upgrade} =websocket [NC]
    RewriteRule /(.*) ws://127.0.0.1:1443/$1 [P,L]

    # Otherwise redirect it to a normal HTTP connection
    RewriteRule ^/(.*)$ http://127.0.0.1:1443/$1 [P,QSA]
    ProxyPassReverse  "/" "http://127.0.0.1:1443"
```
