Check out files with happiness linter
const gulp = require('gulp');
const gulpHappiness = require('gulp-happiness');
gulp.task('lint', function () {
return gulp.src(['**/*.js','!node_modules/**'])
// Attaches the lint data to the "eslint" property
// of the file object so it can be used by other modules.
// By default it will skip files with empty content
// and if filename starts with _ (underscore)
.pipe(gulpHappiness())
// eslint.format() outputs the lint results to the console.
.pipe(gulpHappiness.format())
// Look after checking all the streamed files,
// and if at least one of them has errors it will fail.
// Note! This method does not transfer files further to the stream!
.pipe(gulpHappiness.failAfterError());
});
Lint files, fix and transfer
const gulp = require('gulp');
const gulpHappiness = require('gulp-happiness');
gulp.task('lint', function () {
return gulp.src('./src/scripts/**/*.js')
// Enable fixing - fix: true.
// If auto fixing cannot be done,
// you will see message in console about it
.pipe(gulpHappiness({
fix: true
}))
// Show in console happy files ;)
.pipe(gulpHappiness.format({
showHappyFiles: true
}))
// Failing if file has eslint errors,
// it will break task immediately.
// Current file and all next not will be transferred
.pipe(gulpHappiness.failOnError())
// transfer files
.pipe(gulp.dest('./dist/assets/js/'));
});

Example with custom formatter function
const gulp = require('gulp');
const gulpHappiness = require('gulp-happiness');
gulp.task('lint', function () {
return gulp.src(['**/*.js','!node_modules/**'])
.pipe(gulpHappiness())
.pipe(gulpHappiness.format(function(results, formatterOptions={}) {
// process results and options
// ...
let output = myOwnMethodForTransformResults(results, transformOptions);
return output;
