    Async-Exec

    TypeScript

    Have you ever wanted to exec things asyncly? Now you can!

    Usage

    npm install -S async-exec

    Then in your code use any of the following patterns:

    Default

    The default export is intended to be pretty convenient.

    import exec from 'async-exec';
    

    exec(command: string, log: boolean)

    Run a single command expressed as a string and return the stdout when complete.

    await exec(`osascript -e "set volume ${scaledVolume}"`);
    const tsFiles = await exec(`find . -name "*.ts"`);
    

    For tee-style logging, where the output is both sent to stdout as it arrives, and captured in the return value, set the second argument to true.

    exec('ls', true);
    

    Other Exports

    These other functions are provided in case they are useful.

    execAndLog(command: string)

    In addition to returning the stdout, this function will console.log each line.

    execWithCallbackOnLine(command: string, funcForLine: (line: string) => any)

    Run a command, return the stdout and call a function for each line of output. You could use this to console.log only the lines you want.

    execWithCallbackOnData(command: string, funcForData: ((data: Object) => any) = null)

    Run a command, return stdout and call a function on every 'data' event. This function gives you access to the raw data which you can parse any way you'd like for your situation.

    Go ahead and send me PRs. I love them. Especially if they contain tests and don't check in generated files.

    Not sure how to fix it yourself? Submit an issue and we'll get it done eventually!
