Error in Gulp caused by attempting to minify JavaScript files

I've been struggling with this issue for the past 2 days and I'm a bit of a novice when it comes to task runners. I decided to ask for help because I can't seem to figure it out on my own.

Currently, I am using Gulp with Slush generated by this package: https://www.npmjs.com/package/slush-webapp

Running ´gulp serve´ works fine without any issues.

However, when I run ´gulp´, I encounter an error during the JavaScript minification process. The error can be seen here: http://pastebin.com/4mPq2jEU

From what I've observed, the CSS is being minified correctly and the images are loading as expected.

Upon inspecting the console in Chrome, I see an error related to an "undefined function."

I've tried adding the following at the beginning of my .js files (jquery plugins) to resolve the issue:

'use strict';

I've also attempted to use closures, but nothing seems to be working.

Any assistance would be greatly appreciated. Thank you,

Jorge

Answer №1

When you add third-party libraries to your app folder that do not follow JSHint rules, it can result in a lengthy error stack. Here are some steps you can take:

  1. Edit your Gulpfile and remove the JSHint task from your build process:

    gulp.task('build', ['lint', 'html', 'images', 'fonts', 'misc']);

/* to */

gulp.task('build', ['html', 'images', 'fonts', 'misc']);

  2. Exclude the third-party scripts from the linting task:

    gulp.task('lint', function () {
    var jshint = require('gulp-jshint');

    return gulp.src(['app/scripts/**/*.js', '!app/script/path/to/script/that/fails.js'])
        .pipe(jshint())
        .pipe(jshint.reporter('default'));
});

  3. Move files that do not adhere to JSHint rules to a separate folder.

If you find it challenging to make your own files JSHint compliant, you can start by following step 1 for a quick solution. However, it's essential to delve deeper into dependency management and linting practices for a better understanding.
