    Programmable interface to clinic doctor

    banner

    Supported node versions

    • Node.js 9.4.0 and above
    • Node.js 8.10.0 and above

    Node.js 8.9.4 also works, however you have to listen to SIGINT and shutdown the process nicely. You can find examples in node-clinic-doctor-examples

    Example

    const ClinicDoctor = require('clinic-doctor')
    const doctor = new ClinicDoctor()
     
    doctor.collect(['node', './path-to-script.js'], function (err, filepath) {
      if (err) throw err
     
      doctor.visualize(filepath, filepath + '.html', function (err) {
        if (err) throw err
      });
    })

    Documentation

    const ClinicDoctor = require('clinic-doctor')
    const doctor = new ClinicDoctor()

    doctor.collect(args, callback)

    Starts a process by using:

    const { spawn } = require('child_process')
    spawn(args[0], ['-r', 'sampler.js'].concat(args.slice(1)))

    The injected sampler will produce a file in the current working directory, with the process PID in its filename. The filepath relative to the current working directory will be the value in the callback.

    stdout, stderr, and stdin will be relayed to the calling process. As will the SIGINT event.

    doctor.visualize(dataFilename, outputFilename, callback)

    Will consume the datafile specified by dataFilename, this datafile will be produced by the sampler using doctor.collect.

    doctor.visualize will then output a standalone HTML file to outputFilename. When completed the callback will be called with no extra arguments, except a possible error.
