gulp-run-seq-unique

this hack make when we run a task like run-sequence, the dep task will not run > 1 time

install

npm install gulp-run-seq-unique

by the default this value is true

when u wanna disable this hack like old run-sequence do, u can set value as false

demo

replace run-sequence

import * as gulp from 'gulp';
import * as runSequence from 'run-sequence';

gulp.task('task-name', function ()
{
	return;
});

let callback = function (...ret)
{
	console.log(this, ret);
};

runSequence.use(gulp);
runSequence('task-name', callback);

to

import * as gulp from 'gulp';
import runSequence from 'gulp-run-seq-unique/run-sequence';

gulp.task('task-name', function ()
{
	return;
});

let callback = function (...ret)
{
	console.log(this, ret);
};

runSequence.use(gulp);
runSequence('task-name', callback);
