gulp-csstree v1.0.1

gulp-csstree

CSS Tree lint plugin for gulp 3

Usage

First, install gulp-csstree as a development dependency:

npm install --save-dev gulp-csstree

Then, add it to your gulpfile.js:

var csstree = require('gulp-csstree');

gulp.task('css', function () {
    gulp.src('./styles/*.css')
        .pipe(csstree())
        .pipe(gulp.dest('build'));
});

Options

formatter

var csstree = require('gulp-csstree');

gulp.task('css', function () {
    gulp.src('./styles/*.css')
        .pipe(csstree({ formatter: formatterFn }))
        .pipe(gulp.dest('build'));
});

formatterFn is a function like this:

function formatterFn(report, file) {
    // some code, that outputs a report data...
}

Formatter function will be called for every file which has an invalid css.

Fail on errors

Pipe the file stream to csstree.failAfterError() to fail on errors.

var csstree = require('gulp-csstree');

gulp.task('css', function () {
    gulp.src('./styles/*.css')
        .pipe(csstree())
        .pipe(csstree.failAfterError())
        .pipe(gulp.dest('build'));
});
