Usage
This is an example of gulpfile.js.
const gulp = require('gulp');
const images = require('gulp-is-images');
gulp.task('images', function () {
gulp.src('src/images/**/*')
.pipe(images())
.pipe(gulp.dest('dist/images/'));
});
gulp.task('default', ['images']);
You can pass an object to images() as argument such as following:
gulp.task('images', function () {
gulp.src('src/images/**/*')
.pipe(images({
pngquant: true,
optipng: false,
zopflipng: true,
jpegRecompress: false,
jpegoptim: true,
mozjpeg: true,
gifsicle: true,
svgo: true,
concurrent: 10
}))
.pipe(gulp.dest('dist/images/'));
});
Set false for optimizers which you don't want to apply. And you can set concurrent option to limit the max concurrency in execution.
Optionally you may pass enable and disable options to svgo:
gulp.task('images', function () {
gulp.src('src/images/**/*')
.pipe(images({
svgo: { enable: ["removeRasterImages"], disable: ["removeDoctype"] }
}))
.pipe(gulp.dest('dist/images/**/*'));
});
