process-suspend v0.0.5

Suspend and Resume processes at will

This module rides on the amazing ntsuspend to provide a cross platform way to suspend and resume child processes in NodeJs.

This is occasioned by the fact that Windows does not support SIGSTOP and SIGCONT signals.

Install via yarn add process-suspend and have fun.

    const { spawn } = require('child_process');
    const sProc = require("process-suspend");

    // start your our funky process...
    const ourFunkyProcess = spawn("run.cmd");

    // then bind to the ourFunkyProcess
    sProc.bind(ourFunkyProcess);

    // somewhere else in the code, suspend our funky process
    ourFunkyProcess.suspend();

    // do whatever else matters to you...

    // and then resume our funky process
    ourFunkyProcess.resume();

NOTE: You also get a boolean isSuspended added to the process so you can always check the state using process.isSuspended.

Don't Like Binding

There's a school of thought that says you should never tamper with default objects. Coolio.

Simply then suspend and resume as follows.

    const { spawn } = require('child_process');
    const {suspend, resume} = require("process-suspend");

    // start your our funky process...
    const ourFunkyProcess = spawn("run.cmd");

    // somewhere else in the code, suspend our funky process
    suspend(ourFunkyProcess);

    // do whatever else matters to you...

    // and then resume our funky process
    resume(ourFunkyProcess);

NOTE: Please use spawn and not exec with this module.
