Issues with the output should be reported on the JSCS issue tracker.

$ npm install --save-dev gulp-jscs
const gulp = require('gulp');
const jscs = require('gulp-jscs');
 
gulp.task('default', () => {
    return gulp.src('src/app.js')
        .pipe(jscs())
        .pipe(jscs.reporter());
});
const gulp = require('gulp');
const jscs = require('gulp-jscs');
 
gulp.task('default', () => {
    return gulp.src('src/app.js')
        .pipe(jscs({fix: true}))
        .pipe(gulp.dest('src'));
});
const gulp = require('gulp');
const jscs = require('gulp-jscs');
 
gulp.task('default', () => {
    return gulp.src('src/app.js')
        .pipe(jscs({fix: true}))
        .pipe(jscs.reporter())
        .pipe(jscs.reporter('fail'))
        .pipe(gulp.dest('src'));
});

A jscs object will be attached to the file object.
An example with one error might look like this:

{
    success: false,  // or true if no errors 
    errorCount: 1,   // number of errors in the errors array 
    errors: [{       // an array of jscs error objects 
        filename: 'index.js',  // basename of the file 
        rule: 'requireCamelCaseOrUpperCaseIdentifiers',  // the rule which triggered the error 
        message: 'All identifiers must be camelCase or UPPER_CASE',  // error message 
        line: 32,  // error line number 
        column: 7  // error column 
    }]
};

JSCS config should be placed in a .jscsrc file.

Type: boolean
Default: false

Make JSCS attempt to auto-fix your files.
Be sure to pipe to gulp.dest if you use this option.

Type: string
Default: JSCS will search for the config file up to your home directory.

Set the path to the JSCS config file.
Only use this option when it can't be found automatically.

Type: string
Default: console

See the JSCS reporter docs for supported input.

Can be used multiple times in the same pipeline.

This plugin also ships with some custom reporters:

  • fail - Emits an error at the end of the stream if there are lint errors.
  • failImmediately - Emits an error immediately if there are lint errors.
