gulp-image64
Convert and replace image-files within your DOM/HTML to base64-encoded data.
Example
gulpfile.js
var gulp = require('gulp');
var image64 = require('gulp-image64');
//cheerio load options
var options = {
lowerCaseAttributeNames: false
};
gulp.task('default', function () {
gulp.src('index.html')
.pipe(image64(options))
.pipe(gulp.dest('path'));
});index.html // Before...
<html>
<head>
</head>
<body>
<img src="sample.png" />
...path/index.html // ...after:
<html>
<head>
</head>
<body>
<img src="data:image/png;base64,...">
...This plugin uses cheerio so any options passed in image64(options) function call will be passed into cheerio.load function. See here for complete list of options.
