gulp-remove-use-strict's Issues

没有效果，可以尝试https://blog.csdn.net/snailmar/article/details/106840143

使用这个插件就可以了

remove use strict does not work

const gulp = require('gulp')
const del = require('del')
const removeUseStrict = require('gulp-remove-use-strict')

gulp.task('remove-strict', ['remove-strict:clean'], function () {
return gulp.src('./dist/static/js/*.js')
.pipe(removeUseStrict())
.pipe(gulp.dest('./dist/newJS/'))
})
gulp.task('remove-strict:clean', [], function () {
return del(['./dist/newJS/'], { force: true })
})

Not working (gulp 4)

Getting this error:

TypeError: through.obj is not a function

Changed this line:

// return through.obj(removeUseStrict);
return through({ objectMode: true }, removeUseStrict);

(at least no error) but still doesn't work, 'use strict' text still present in output.

Interferes with gulp-uglify

I get this error only when using gulp-remove-use-strict.

Duplicate data property in object literal not allowed in strict mode

Task:

gulp.task('scripts', function() {

function createErrorHandler(name) {
return function (err) {
console.error('Error from ' + name + ' in compress task', err.toString());
};
}

return gulp.src(srcDir + '/app/**/*.js')
.on('error', createErrorHandler('gulp.src'))
.pipe(removeUseStrict())
.on('error', createErrorHandler('remove'))
.pipe(sourcemaps.init())
.pipe(concat('app.min.js'))
//.pipe(gulpif(!dist, uglify()))
.pipe(gulpif(!dist, gulp.dest(devDir + '/scripts/')))
.pipe(gulpif(!dist, connect.reload()))
.pipe(gulpif(dist, uglify())) // gulpif(dist, uglify())
.on('error', createErrorHandler('uglify'))
.pipe(gulpif(dist, stripDebug()))
.on('error', createErrorHandler('strip'))
.pipe(gulpif(!dist, sourcemaps.write('/')))
.pipe(gulpif(dist, gulp.dest(distDir + '/scripts/')))
.on('error', createErrorHandler('gulp.dest'));
});

It gives me this error:

无效，还是一样会添加'use strict';

我的配置如下：

var removeUseStrict = require("gulp-remove-use-strict");

// 压缩js文件
gulp.task('minify-js', function (done) {
    return gulp.src(['./public/**/*.js', '!./public/**/*.min.js'])
        .pipe(babel({
            //将ES6代码转译为可执行的JS代码
            presets: ['es2015'] // es5检查机制
        }))
        .pipe(uglify())
        .pipe(removeUseStrict()) //取消严格模式方法("use strict")
        .pipe(gulp.dest('./public'));
    done();
});
