The web server configuration parameter port specifies the TCP port on which the server will listen for connections. The default value is 8080.

The port parameter accepts two types of value:

• Numerical values are interpreted as a decimal port number
  • The special value 0 (zero) causes the operating system to assign an available port
• Non-numeric values are interpreted as an environment variable from which the port should be read

This example configures the server to listen on port 8090:

tiddlywiki mywikifolder --listen port=8090

This example configures the server to listen on the port specified in the environment variable THE_PORT:

tiddlywiki mywikifolder --listen port=THE_PORT
