Guillaume Plique thinks so. You might remember him from the Baobab interview. If not, look that up if you want to know more about him. Let's let him tell us more about a tool known as kotatsu and his ideas behind it.
kotatsu is a straightforward CLI tool enabling JS developers to start working on a new project very fast and with as few boilerplate as possible. This means the tool will out of the box handle ES2015 for you, bundle, serve your code and handle Hot Module Replacement (HMR) without forcing you to write complex configuration files or tweaking your own dev express server.
And all of this can be as easy as the following command:
kotatsu serve --es2015 ./js/main.js
Initially, I started developing kotatsu because I wanted to have HMR in Node.js. The thing is, after HMR started being a thing in the browser, I grew quite fond of it and, as a result, I was infuriated by the time needed to reload node.js scripts such as my express server. And even tools like nodemon were too slow and were furthermore wiping the state of my server application.
So the first goal was indeed to make webpack's HMR a thing also on the server side. This was already possible, but really tiresome to setup on your own. So I developed kotatsu to abstract the problem and be able to setup it more quickly on some other projects.
But after some time using the tool, I found that it could also solve some issues related to the client-side and so I extended the tool to this related universe.
The thing is nowadays, JS dev environment has become quite complex if you want to beneficiate from the latest advances: ES2015, ES2016, browser bundling, HMR etc. My point is not to say I regret ye old times - you won't find me saying that - but just to note that it is quite tedious a task to setup your dev environment. Because you need a lot of boilerplate, a lot of complex configuration files etc. And, what's more, in a lot of projects you always end up needing the same things.
So, the philosophy of kotatsu is the following: setup your project in a modern JS dev environment as fast as possible without boilerplate nor configuration, just the CLI tool, and only add/replace more specific parts of the stack on the fly when you start needing them.
First of all, I need to do some maintenance work on the tool to ensure it works on every platform consistently etc. and remain sure it stays up to date with JS tooling (Babel, webpack etc.). I must also ensure that one is still able to forfeit parts of the tool, or even drop the tool altogether, without any difficulties when customizing the stack very specifically to meets one's needs.
I also want to add some new features but I must not go too far lest it would become another complex tool on the scale of the tools I currently abstract away for the user.
Finally, I would love being able to write some unit tests for the tool but I find it very difficult to do so because of the amount of IO, system etc. the tool relies upon (any help on the subject would be gladly accepted :) ).
This means, we'll see more HMR goodies, more developer tools such as the one we can already see for frameworks & libraries and not only for the JS language itself etc.
Thanks for the interview Guillaume! I will definitely keep an eye on Kotatsu. I have some ideas of my own on how to get rid of some of that boilerplate baggage we are carrying around. Most likely our ideas will converge somehow at some point.
If you want to try out the tool, check out kotatsu project page on GitHub. You should find enough information there to get started. And I'm sure Guilllaume will value feedback!
