gulp-stylelint
A Gulp plugin that runs stylelint results through a list of reporters.
Installation
npm install stylelint gulp-stylelint --save-dev
Quick start
Once you have configured stylelint (e.g. you have a .stylelintrc file), start with the following code. You will find additional configuration options below.
const gulp = require('gulp');
gulp.task('lint-css', function lintCssTask() {
const gulpStylelint = require('gulp-stylelint');
return gulp
.src('src/**/*.css')
.pipe(gulpStylelint({
reporters: [
{formatter: 'string', console: true}
]
}));
});
Formatters
Below is the list of currently available stylelint formatters. Some of them are bundled with stylelint by default and exposed on gulpStylelint.formatters
object. Others need to be installed. You can write a custom formatter to tailor the reporting to your needs.
"string"
(same asgulpStylelint.formatters.string
) – bundled with stylelint"verbose"
(same asgulpStylelint.formatters.verbose
) – bundled with stylelint"json"
(same asgulpStylelint.formatters.json
) – bundled with stylelint- stylelint-checkstyle-formatter – requires installation
Options
gulp-stylelint supports all stylelint options except files
and formatter
and accepts a custom set of options listed below:
const gulp = require('gulp');
gulp.task('lint-css', function lintCssTask() {
const gulpStylelint = require('gulp-stylelint');
const myStylelintFormatter = require('my-stylelint-formatter');
return gulp
.src('src/**/*.css')
.pipe(gulpStylelint({
failAfterError: true,
reportOutputDir: 'reports/lint',
reporters: [
{formatter: 'verbose', console: true},
{formatter: 'json', save: 'report.json'},
{formatter: myStylelintFormatter, save: 'my-custom-report.txt'}
],
debug: true
}));
});
failAfterError
When set to true
, the process will end with non-zero error code if any error-level warnings were raised. Defaults to true
.
reportOutputDir
Base directory for lint results written to filesystem. Defaults to current working directory.
reporters
List of reporter configuration objects (see below). Defaults to an empty array.
{
// stylelint results formatter (required):
// - pass a function for imported, custom or exposed formatters
// - pass a string ("string", "verbose", "json") for formatters bundled with stylelint
formatter: myFormatter,
// save the formatted result to a file (optional):
save: 'text-report.txt',
// log the formatted result to console (optional):
console: true
}
debug
When set to true
, the error handler will print an error stack trace. Defaults to false
.
Autofix
The fix: true
option instructs stylelint to try to fix as many issues as possible. The fixes are applied to the gulp stream. The fixed content can be saved to file using gulp.dest
.
const gulp = require('gulp');
gulp.task('fix-css', function fixCssTask() {
const gulpStylelint = require('gulp-stylelint');
return gulp
.src('src/**/*.css')
.pipe(gulpStylelint({
fix: true
}))
.pipe(gulp.dest('src'));
});
