Client Options

ttyd has a mechanism to pass server side command-line arguments to the browser page which is called client options:

-t, --client-option     Send option to client (format: key=value), repeat to add more options

Basic usage

• -t rendererType=webgl: use the experimental webgl renderer for xterm.js
• -t disableLeaveAlert=true: disable the leave page alert (#294)
• -t disableResizeOverlay=true: disable the terminal resize overlay (#446)
• -t titleFixed=hello: set a fixed title for the browser window (#133)
• -t fontSize=20: change the font size of the terminal

Advanced usage

You can use the client option to change all the settings of xterm defined in ITerminalOptions, examples:

• -t cursorStyle=bar: set cursor style to bar
• -t lineHeight=1.5: set line-height to 1.5
• -t 'theme={"background": "green"}': set background color to green

to try the example options above, run:

ttyd -t cursorStyle=bar -t lineHeight=1.5 -t 'theme={"background": "green"}' bash
