# Local Development ## Install First, [Install docker with docker-compose.](https://docs.docker.com/compose/install/) Then, clone the repository and run docker-compose: ```shell git clone https://github.com/schlagmichdoch/pairdrop.git ``` ```shell cd pairdrop ``` ```shell docker-compose up -d ``` Now point your browser to `http://localhost:8080`. - To restart the containers run `docker-compose restart`. - To stop the containers run `docker-compose stop`. - To debug the NodeJS server run `docker logs pairdrop_node_1`.
## Testing PWA related features PWAs require that the app is served under a correctly set up and trusted TLS endpoint. The nginx container creates a CA certificate and a website certificate for you. To correctly set the common name of the certificate, you need to change the FQDN environment variable in `docker/fqdn.env` to the fully qualified domain name of your workstation. If you want to test PWA features, you need to trust the CA of the certificate for your local deployment. For your convenience, you can download the crt file from `http://:8080/ca.crt`. Install that certificate to the trust store of your operating system. - On Windows, make sure to install it to the `Trusted Root Certification Authorities` store. - On MacOS, double click the installed CA certificate in `Keychain Access`, expand `Trust`, and select `Always Trust` for SSL. - Firefox uses its own trust store. To install the CA, point Firefox at `http://:8080/ca.crt`. When prompted, select `Trust this CA to identify websites` and click OK. - When using Chrome, you need to restart Chrome so it reloads the trust store (`chrome://restart`). Additionally, after installing a new cert, you need to clear the Storage (DevTools -> Application -> Clear storage -> Clear site data). Please note that the certificates (CA and webserver cert) expire after a day. Also, whenever you restart the nginx docker, container new certificates are created. The site is served on `https://:8443`. # Deployment Notes The client expects the server at http(s)://your.domain/server. When serving the node server behind a proxy, the `X-Forwarded-For` header has to be set by the proxy. Otherwise, all clients that are served by the proxy will be mutually visible. ## Deployment with node ```bash git clone https://github.com/Bellisario/node-snapdrop.git && cd node-snapdrop ``` Install all dependencies with NPM: ```bash npm install ``` Start the server with: ```bash npm start ``` ### Public Run If you want to run in your public "sharable" IP instead of locally, you can use this command: ```bash node index.js public ``` or ```bash npm start ``` > Remember to check your IP Address using your OS command to see where you can access the server. > By default, the node server listens on port 3000. #### Automatic restart on error ```bash npm start -- --auto-restart ``` #### Rate limiting requests: ```bash npm start -- --rate-limit ``` #### Production (autostart and rate-limit) ```bash npm start:prod ``` ## HTTP-Server You must use nginx or apache to set the x-forwarded-for header correctly. Otherwise, all clients will be mutually visible. ### Using nginx ``` server { listen 80; expires epoch; location / { root /var/www/pairdrop/client; index index.html index.htm; } location /server { proxy_connect_timeout 300; proxy_pass http://node:3000; proxy_set_header Connection "upgrade"; proxy_set_header Upgrade $http_upgrade; proxy_set_header X-Forwarded-for $remote_addr; } } server { listen 443 ssl http2; ssl_certificate /etc/ssl/certs/pairdrop-dev.crt; ssl_certificate_key /etc/ssl/certs/pairdrop-dev.key; expires epoch; location / { root /var/www/pairdrop/client; index index.html; } location /server { proxy_connect_timeout 300; proxy_pass http://node:3000; proxy_set_header Connection "upgrade"; proxy_set_header Upgrade $http_upgrade; proxy_set_header X-Forwarded-for $remote_addr; } } ``` ### Using Apache ``` DocumentRoot "/var/www/pairdrop/client" DirectoryIndex index.html RewriteEngine on RewriteCond %{HTTP:Upgrade} websocket [NC] RewriteCond %{HTTP:Connection} upgrade [NC] RewriteRule ^/?(.*) "ws://127.0.0.1:3000/$1" [P,L] DocumentRoot "/var/www/pairdrop/client" DirectoryIndex index.html RewriteEngine on RewriteCond %{HTTP:Upgrade} websocket [NC] RewriteCond %{HTTP:Connection} upgrade [NC] RewriteRule ^/?(.*) "wws://127.0.0.1:3000/$1" [P,L] ``` ## Deployment with Docker The easiest way to get Pairdrop up and running is by using Docker. By default, docker listens on ports 8080 (http) and 8443 (https) (specified in `docker-compose.yml`). When running Pairdrop via Docker, the `X-Forwarded-For` header has to be set by a proxy. Otherwise, all clients will be mutually visible. ### Installation [See Local Development > Install](#install) Use nginx or apache to set the header correctly: ### Using nginx (This differs from the config under `/docker/nginx/default.conf) ``` server { listen 80; expires epoch; location / { proxy_connect_timeout 300; proxy_pass http://127.0.0.1:8080; } location /server { proxy_connect_timeout 300; proxy_pass http://127.0.0.1:8080; proxy_set_header Connection "upgrade"; proxy_set_header Upgrade $http_upgrade; proxy_set_header X-Forwarded-for $remote_addr; } } server { listen 443 ssl http2; ssl_certificate /etc/ssl/certs/pairdrop-dev.crt; ssl_certificate_key /etc/ssl/certs/pairdrop-dev.key; expires epoch; location / { proxy_connect_timeout 300; proxy_pass http://127.0.0.1:443; } location /server { proxy_connect_timeout 300; proxy_pass http://127.0.0.1:443; proxy_set_header Connection "upgrade"; proxy_set_header Upgrade $http_upgrade; proxy_set_header X-Forwarded-for $remote_addr; } } ``` ### Using Apache install modules `proxy`, `proxy_http`, `mod_proxy_wstunnel` ```shell a2enmod proxy ``` ```shell a2enmod proxy_http ``` ```shell a2enmod proxy_wstunnel ```
Create a new configuration file under `/etc/apache2/sites-available` (on debian) **pairdrop.conf** ``` ProxyPass / http://127.0.0.1:8080/ RewriteEngine on RewriteCond %{HTTP:Upgrade} websocket [NC] RewriteCond %{HTTP:Connection} upgrade [NC] RewriteRule ^/?(.*) "ws://127.0.0.1:8080/$1" [P,L] ProxyPass / https://127.0.0.1:8443/ RewriteEngine on RewriteCond %{HTTP:Upgrade} websocket [NC] RewriteCond %{HTTP:Connection} upgrade [NC] RewriteRule ^/?(.*) "wws://127.0.0.1:8443/$1" [P,L] ``` Activate the new virtual host and reload apache: ```shell a2ensite pairdrop ``` ```shell service apache2 reload ``` [< Back](/README.md)
