Footprint

Working with ES6, Babel/Babelify, Browserify? This is for you!

• Node module for reorganizing redundant code. Each Transform is just a method that takes in a text string and can be used by itself.
• Wrote this so I can be at peace migrating to ES6 early and using Browserify and because being bloated bugs me cough jQuery.
• Minimizes the footprint on Babel concatinated files like a Browserify bundle.
• Works on minified (minified with uglify) and non-minified code against any style formatting! (the output is kept in original form for debuggin purposes so even though it will rip against uglified code, you will need to re-uglify after which uglifying should always be done last in the build process anyway)

Development

Requirements

• nodejs
• npm install -g gulp
• npm install

Test

gulp test

Usage

Installation

npm install chickendinosaur-footprint

How to use...

Transform types

• footprint.Transform.usestrict
• footprint.Transform.babel (uses footprint.Transform.usestrict)

Using the transformer in debug

var footprint = require('chickendinosaur-footprint');

footprint.Transformer({
        debug:true
    })
    .src('./test/mock/babelMock.dirty.js')
    .transform(footprint.Transform.babel)
    .dest('./dist/babelMock.transformed.js');

Using a transform as standalone

var footprint = require('chickendinosaur-footprint');
var fs = require('fs');

var text = fs.readFileSync('./test/mock/babelMock.dirty.js', 'utf-8');

var output = footprint.Transform.babel(text);

Chaining Transforms

var footprint = require('chickendinosaur-footprint');

footprint.Transformer({
    debug:true
})
.src('./test/mock/babelMock.dirty.js')
.transform(footprint.Transform.babel)
.transform(footprint.Transform.usestrict)
.dest('./dist/babelMock.transformed.js')

Chaining multiple input/outputs

var footprint = require('chickendinosaur-footprint');

footprint.Transformer({
    debug:true
})
.src('./test/mock/usestrictMock.dirty.js')
.transform(footprint.Transform.usestrict)
.dest('./dist/usestrictMock.transformed.js')
.src('./test/mock/babelMock.dirty.js')
.transform(footprint.Transform.babel)
.dest('./dist/babelMock.transformed.js');

Example

Using the footprint.Transform.usestrict Transform

var footprint = require('chickendinosaur-footprint');

gulp.task('footprint', function() {
    footprint.Transformer({
        debug:true
    })
    .src('./test/mock/usestrictMock.dirty.js')
    .transform(footprint.Transform.usestrict)
    .dest('./dist/usestrictMock.transformed.js');
});

Before

'use strict' "use strict" 'use strict'; "use strict";

After

"use strict";

Results

Input:

• ./test/mock/usestrictMock.dirty.js
• 0.0560 KB

Transform:

• usestrict

Difference:

• 0.0430 KB
• 76.7857 %

Output:

• ./dist/usestrictMock.transformed.js
• 0.0130 KB

Release Notes

v0.1.6

• Added consolidatoin for require/_interopRequireDefault statements.
• Changed all output to original form instead of uglified version since you will have to uglify after anyway.
