How well do you need to know Webpack and Gulp in web development?

Question

Web development

Hello.
I wrote various bicycles for myself on react, and it's time to develop full-fledged projects, but I haven’t moved away from react yet outside the dev-server, and I don’t really know how to put the project into production and apply all sorts of hot module replacements with it, I tried to delve into webpack , he immediately let me know about his complexity, also I think Gulp is important, they can do general things, but they also say that they are intended for different purposes. And how are they used together? When to use Gulp and when to use Webpack. How much webpack for React-Redux do I need to learn, should I start with version 2?

Answer 1

With react, webpack is used in the vast majority of cases. There are a ton of ready-made configs that you can just copy-paste and everything will work. But in general - in the project you may need to do something differently and then difficulties arise. Therefore, for general development, you need to at least superficially understand what's what (ideally, try such chips as tree shaking and code splitting).
My advice is to just start building the project from scratch. Look at ready-made configs and gradually build your own, while reading the documentation. When applying for a job, it will definitely be a plus, and it’s not all the same to use create-react-app in your own development.
PS I don’t know about gulp, I haven’t had to use it live for a long time: all you need is webpack

Answer 2

90% don't know.
Whether you need it is up to you.

New-fangled technologies only make life easier, nothing more. It is completely optional to use them.
On the other hand, they make life so much easier. And not that hard to learn.
Well, these buzzwords are highly valued in the labor market.
