grunt-inline-images v0.3.0
grunt-inline-images
Change all URLs matching a pattern to inline base64 representations or about:blank.
Getting Started
This plugin requires Grunt.
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-inline-images --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-inline-images');
The "inlineImages" task
Overview
The inlineImages
task job is to:
- download and inline (base64-encoded) images from URLs matching one of
toInline
patterns - change URLs matching one of
toDiscard
patterns toabout:blank
In this way, if one has an example JSON file with mock data, after such a transformation it no longer refers to external files which can help in unit testing since tests won't trigger HTTP requests, making them faster and not rely on active internet connection.
In your project's Gruntfile, add a section named inlineImages
to the data object passed into grunt.initConfig()
.
grunt.initConfig({
inlineImages: {
options: {
// Task-specific options go here.
},
your_target: {
// Target-specific file lists and/or options go here.
},
},
})
Options
The inlineImages
task accepts a couple of options:
{
toInline: [], // beginnings of URLs to images to be inlined in a base64 representation
toDiscard: [], // beginnings of URLs to be changed to "about:blank"
}
Usage Examples
'use strict';
grunt.initConfig({
inlineImages: {
all: {
options: {
toInline: [ // beginnings of URLs to images to be inlined in a base64 representation
'example.com/',
'raw\\.githubusercontent\\.com/',
],
toDiscard: [ // beginnings of URLs to be changed to "about:blank"
'(player\\.|)vimeo\\.com/',
'youtube\\.com/',
'facebook\\.com/',
],
},
files: {
'test/tmp/actual.json': ['test/fixtures/input.json'],
},
},
},
});
grunt.loadNpmTasks('grunt-inline-images');
You can see an example input file in test/fixtures/input.json and the transformed output file in test/fixtures/expected.json.
Supported Node.js versions
This project aims to support all Node.js LTS versions in the "active" phase (see LTS README for more details) as well as the latest stable Node.js.
