Multilaunch

This is a utility for launching multiple processes and toggling between them to view their logs.

Usage:

npx multilaunch config.json

Example config:

[
    {
        // name for the command in the sidebar
        "name": "Start Backend", 
        // the shell command to run
        "command": "rush start-backend", 
        // the cwd to run from
        "cwd": "./backend", 
         // if applicable, a string to look for to indicate the process has started up
        "startedWhen": "Server ready at",
        // a section for grouping commands under a section heading, commands still need to be consecutive
        // the section is rendered when it is different from the previous command's section
        "section": "Backend"
    },
    {
        "name": "Start Frontend",
        "command": "rush start-frontend",
        "cwd": "./frontend",
        "startedWhen": "Compiled successfully!",
        "section": "Frontend"
    }
]

When started, usage is fairly self-explanatory:

• Up/Down to navigate
• Enter to start/restart a process
• Ctrl+C to stop a process
• D to dump the current log to disk
• Esc to quit multilaunch (and stop underlying processes)
• [/] to scroll/up and down in the log (shift for faster scrolling)
• Space to go back to the bottom of the log

Mouse scroll moves the log up and down, but you mean need to tweak terminal settings for this. Cmder - under Keys & Macro > Mouse > Send mouse events to console iTerm2 - Profiles > Terminal > Uncheck 'Save lines to scrollback in alternate screen mode'
