Generic asset size comparison and reporting tool

Installation

npm install -g asset-size-reporter

Usage

Print asset sizes to the console:

$ asset-size-reporter "dist/*.js"

dist/bar.js: 13.6 kB / 1.20 kB gzip 
dist/foo.js: 42.3 kB / 2.32 kB gzip 

Total: 55.9 kB / 3.52 kB gzip 

Write asset size report to a JSON file:

$ asset-size-reporter "dist/*.js" --json > asset-size-report.json

Compare asset sizes to a previous reports:

$ asset-size-reporter "dist/*.js" --compare=previous.json

dist/bar.js: 13.6 kB -> 13.8 kB (+213 Byte) / 1.20 kB -> 1.21 kB (+25 Byte) gzip 
dist/baz.js: 11.2 kB / 1.04 kB gzip (new file) 
[dist/foo.js]: 42.3 kB / 2.32 kB gzip (deleted file) 

Total: 55.9 kB -> 25.0 kB (-30.9 kB) / 3.52 kB -> 2.25 kB (-1.27 kB) gzip 

Configuration

Instead of defining the asset search paths on the command line it is also possible to create an asset-size-reporter.config.json file that contains the configuration.

Possible configuration options are:

• patterns – string[] – An array of glob patterns that describe what files should be considered by the asset-size-reporter

  {
    "patterns": [
      "dist/*.css",
      "dist/*.js",
      "!dist/tests.js"
    ]
  }

• gzip – boolean|number – Turn gzip reporting on/off or set a specific gzip compression level (default: true)

• brotli – boolean|number – Turn brotli reporting on/off or set a specific brotli compression level (default: false)
