I've been using Gulp for a couple of months now, it's great! It's like Grunt, but faster, and the tasks are written in code, not a giant JSON config file.
Even though they are clearly related, Gulp and Grunt are fulfilling different purposes. You should carefully examined your needs before choosing one over another.
I recently switched to Gulp for several projects, and I'm thinking of switching back to Grunt.
Gulp lacks of some important features. For instance, it does not allow to sequentially execute tasks: everything is done in parallel. This could for sure be emulated by using async, but the overhead is not worth it.
On the other side, Grunt does support sequential and parallel tasks execution, but is more verbose and does a lot of file writing on the disk (though it is relatively moderate).
One concrete example for sequential tasks execution (easily done with Grunt):
- Watch JavaScript files, when a modifications is detected:
- lint files -> [JSHint, JSCS]
- if success: launch tests -> [Karma, Mocha]
- if success: notify
- If any failure occurs: notify and abort the sequence
There are ways, like others have said. There is also a callback system you can use to make things sequential, but last time I looked it wasn't well documented
I think you are talking about this[1], indeed you are right.
However, task dependencies allows sequential tasks execution, but that's not very handy as you may want a same task to be executed in two different sequences.
Let's see a simple example on which I honestly struggle to reproduce with Gulp:
The grunt config is javascript, not json. So you can write custom tasks code in your grunt config.
For instance, I wrote a custom tag to modify specific pages to inject javascript include statements in HTML pages. There is probably a plugin for that, but I was able to write the code in 15 minutes so I didn't care.
Yeah, but it's also trivially easy to wrap a 3rd party task in your own task and munge the config at run time. (I'll admit that that pattern didn't become apparent to me until after using Grunt for some months, but once I saw you could do that, many things that seemed onerous got easier.)
