Usage

gulp-browser-compat provides a method for checking against known browser compatibility issues. Can customize which browsers to report on and fail compilation if no support exists for a minimum version of a browser.

package.json:

    "dependencies": {
        "gulp-browser-compat":"git+https://github.com/mozesmagyar/gulp-browser-compat.git#master"
    }

gulpfile.js:

var browserCompatibility = require('gulp-browser-compat');

var compatConfig = {
        'dont_download': false,
        'ignore_unlisted': true,
        'ios_saf': {
                fail:'4.15',
                report: '4.0'
        }
};

function build(options) {
        return gulp.src(entryPoint)
                .pipe(browserify(options.browserify))
                .pipe(metaScript(options.metaScript))
                .pipe(rename(buildName + '.js'))
                .pipe(gulp.dest(buildDir))
                .pipe(uglify(uglifyOptions))
                .pipe(browserCompatibility(compatConfig))
                .pipe(rename(buildName + '.min.js'))
                .pipe(gulp.dest(buildDir));
}
