gulp-fingerprint
Advanced tools
$ npm install --save-dev gulp-fingerprint
Update a source file with fingerprinted assets.
var gulp = require('gulp');
var fingerprint = require('gulp-fingerprint');
// rev-manifest.json produced from gulp-rev
var manifest = require('../../dist/rev-manifest');
gulp.task('default', function () {
var options = {
base: 'assets/',
prefix: '//cdn.example.com/',
verbose: true
};
return gulp.src('.tmp/styles/app.css')
.pipe(fingerprint(manifest, options))
.pipe(gulp.dest('dist'));
});
Type: object, string
Example: rev-manifest.json
produced from using gulp-rev
{
"images/logo.jpg": "images/logo-2d4a1176.jpg",
"images/some-image.png": "images/some-image-abd84705.png",
"images/some-logo2.png": "images/some-logo2-abd84715.png"
}
If a string
is passed in as the manifest, gulp-fingerprint will interpret this as a path and automatically require the json file.
Type: string
Default: regex
Usage: Setting a mode
will change the method of url replacing. There are two methods: regex
and replace
. The replace
method is less accurate but doesn't require specifying a regular expression.
Type: RegExp
Usage: Sets a custom regex to match on your file.
_ Note The default regex, /(?:url\(["']?(.*?)['"]?\)|src=["'](.*?)['"]|src=([^\s\>]+)(?:\>|\s)|href=["'](.*?)['"]|href=([^\s\>]+)(?:\>|\s))/g
, will match:
url('path/to/resource')
url("path/to/resource")
url(path/to/resource)
href='path/to/resource'
href="path/to/resource"
href=path/to/resource
src='path/to/resource'
src="path/to/resource"
src=path/to/resource
Type: string
Usage: Setting a prefix
will prepend the string to a match in the src
...
.pipe(fingerprint(manifest, {prefix: '//cdn.example.com/'}))
...
// Original: `background-image: url("/images/some-logo.png");`
// Replaced: `background-image: url("//cdn.example.com/images/logo-2d4a1176.jpg");` in src file
Type: string
Usage: Setting a base
will remove that string from the beginning of a match in the src
...
.pipe(fingerprint(manifest, {base: 'assets/'}))
...
// Original: `background-image: url("assets/images/some-logo2.png");`
// Replaced: `background-image: url("images/some-logo2-abd84715.png");` in src file
Type: string
Usage: Setting a strip
will remove that string from the beginning of a result path
...
.pipe(fingerprint(manifest, {strip: 'images/'}))
...
// Original: `background-image: url("/images/some-logo2.png");`
// Replaced: `background-image: url("some-logo2-abd84715.png");` in src file
Type: boolean
Usage: Outputs to stdout.
[gulp] gulp-fingerprint Found: images/some-logo.png
[gulp] gulp-fingerprint Replaced: background-image: url("//cdn.example.com/images/logo-2d4a1176.jpg"); }
