Examples

Starting a basic WebSocket server from a specified process:

node-websocketd -e=./examples/myShellScript.sh

Starting a basic WebSocket server from a specified process in a specified port:

Starting a WebSocket server protected with a specified password from a specified process (the process will not execute until recieve the correct password):

node-websocketd -e=./examples/myShellScript.sh -password secr3tp4ssw0rd_123

Starting a TSL WebSocket server from a specified process in a specified port:

node-websocketd -e=./examples/myShellScript.sh --port 9999 --ssl --ssl-key=cert/server.key --ssl-cert=cert/server.crt --ssl-passphrase=123412341234

Starting a TSL WebSocket server from a specified process in a specified port with a specified password (recomended when dealing with sensible data):

node-websocketd -e=./examples/myShellScript.sh --port 9999 --ssl --ssl-key=cert/server.key --ssl-cert=cert/server.crt --ssl-passphrase=123412341234 --password secr3tp4ssw0rd_123

Setting arguments with ENV variables:

NWS_EXEC=./examples/myShellScript.sh NWS_P=9999 NWS_PASSWORD=secr3tp4ssw0rd_123 NWS_SSL=true NWS_SSL_KEY=cert/server.key NWS_SSL_CERT=cert/server.crt NWS_SSL_PASSPHRASE=123412341234 node-websocketd
