gulp-sizereport

Display a report of the size and Gzipped size of your project and trigger alarms when the sizes are higher than expected.

Install

$ npm install --save-dev gulp-sizereport

Usage

A simple usage

var gulp = require('gulp');
var sizereport = require('gulp-sizereport');

gulp.task('sizereport', function () {
    return gulp.src('./dist/*')
        .pipe(sizereport());
});

Options

• title (default: null) Display a title above the table.

• total (default: true) Display the last total row.

• gzip (default: false) Toggle the Gzipped size column.

• fail (default: false) Allows you to fail your Gulp task if a file exceeds a threshold.

var gulp = require('gulp');
var sizereport = require('gulp-sizereport');

gulp.task('sizereport', function () {
    return gulp.src('./dist/*')
        .pipe(sizereport({
            gzip: true
        }));
});

• minifier (default: null) You can add a minifier in order to control the minified size of your source.

var gulp = require('gulp');
var sizereport = require('gulp-sizereport');
var UglifyJS = require('uglify-js');

gulp.task('sizereport', function () {
    return gulp.src('./src/**/*.js')
        .pipe(sizereport({
            minifier: function (contents, filepath) {
                if (filepath.match(/\.min\./g)) {
                    return contents
                }
                return UglifyJS.minify(contents, { fromString: true }).code;
            }
        }));
});

Ideal to control the project size on the fly.

gulp.task('watch', function () {
    gulp.watch('./src/**/*.js', [ 'sizereport'] );
});

Alerts

You can place some alerts on values and files. The value is in Bytes.

• maxSize
• maxGzippedSize
• maxMinifiedSize
• maxMinifiedGzippedSize
• maxTotalSize
• maxTotalGzippedSize
• maxTotalMinifiedSize
• maxTotalMinifiedGzippedSize
