load-perf

Idea

Main idea here is to measure the load(require) time for dependencies and devDependencies for your project or module. we also calculate the load(require) time of your module.
This give an idea about how much time would it take for your module to be required by the consumer.

Key points:

• Measure load performance of your module when its required
• Measure load performance of your dependencies
• Measure load performance of your devDependencies

How to use

Just install the module

 npm install load-perf -g

Then just run the module on your project or module

 load-perf

Options

   -h, --help                  Show help.
  -v, --version               Outputs the version number.
  -p, --package path::String  Package json file path. - default: ./package.json
  -d, --checkDevDependencies  Perf calculation for devDependencies. - default: false
  --no-checkDependencies      Perf calculation for dependencies. - default: true

NodeJs API

You can consume this module programmatically through the Node.js API also.

 var loadPerf = require("load-perf");

var defaultOptions = {
    package: "./package.json",
    checkDevDependencies: false,
    checkDependencies: true
};

var performanceData = loadPerf(defaultOptions);

Even if the options are not supplied to the function, we will use the defaults.
