gulp-xv-webp-html.js

GULP extension for support WEBP images and replace original image tag in HTML

in other words: replace <img> to <picture> for supports webp

Support file extensions: .jpg, .png, .gif, .jpeg, .avif, .svg, .tiff

Package home page: https://www.npmjs.com/package/gulp-xv-webp-html

This NodeJS package is a nice addition to my HTML-template with live update and support SCSS.

P.S.: I wrote this npm-package because others similar had errors and sometimes didn't work correctly with the input data.

Output Example

Example #1

// Input
<img class="lazyload" src="/images/Image.jpg" width="100" height="100">

// Output
<picture>
    <source srcset="/images/Image.webp" type="image/webp">
    <source srcset="/images/Image.jpg" type="image/jpeg">
    <img class="lazyload" src="images/Image.jpg" width="100" height="100">
</picture>

Example #2

// Input
<img src="/images/Image.svg" width="100" height="100">

// Output
<picture>
    <source srcset="images/Image.webp" type="image/webp">
    <source srcset="images/Image.svg" type="image/svg+xml">
    <img src="images/Image.svg" width="100" height="100">

Usage

Given a package.json file that has some dependencies within:

{
  "dependencies": {
    "plugin-error": "^1.0.0",
    "through2": "^4.0.2"
  }
}

Adding this into your Gulpfile.js:

const gulp = require('gulp')
const webpHTML = require("gulp-xv-webp-html")

Example #1

var webpHTML = require('gulp-xv-webp-html');

function html() {
    return  src('./source/*.html')
            .pipe(webpHTML())
            .pipe(gulp.dest('./destHTML/'))
});

exports.html = html;

Example #2

var webpHTML = require('gulp-xv-webp-html');

gulp.task("webpHTML", function(){
    return gulp.src(['./sourceHTML/**/*.html'])
           .pipe(webpHTML())
           .pipe(gulp.dest('./destHTML/'))})

Example #3

var webpHTML = require('gulp-xv-webp-html');

gulp.task("webpHTML", function(){
    return gulp.src(['./sourceHTML/**/*.html'])
           .pipe(webpHTML(['.jpg', '.svg']))
           .pipe(gulp.dest('./destHTML/'))})

Donation & Sponsors

I’ll continue to work and improve the script features regardless of the outcome of funding, because it's rewarding to see that people are using it and it does the job for them. Still I would appreciate your support in covering some of the expenses with the domain hosting and programming hours which are taken from my family time.
