Getting Started with module development

[media_bloke]

I'm a PHP/JS developer, and was asked to help someone build a Magento site. Around 13k SKU's, and doubling in the next few years.

I have the site up and running with a custom theme, and some paid modules, but I want to step up my game and start developing my own modules.

I've tried to find and follow the docs, but there always seems to be an assumption that you already know half of the classes in the framework.

Is there a place with better docs than the official docs? In general, is there a good place to learn custom module development?

I can create a simple module now already, create a db table, and initialize data, but when it comes to something as simple as adding a field to an existing form (like signup), there doesn't seem to be a place to get straightforward answers.

Any resources to help me teach myself would be appreciated.

Thanks

Hi @media_bloke

You can follow below magento documentation.

https://devdocs.magento.com/videos/fundamentals/create-a-new-module/

There are few module creators available as well.

I hope it will help you!

Thanks. As I mentioned, I know how to build the boilerplate of a module. It's the next steps that I don't know where to look.

For example, in the module.xml file, if your module is dependent on another module, you're supposed to reference that other module in the list of <sequence> arguments.

How do you know which other modules to use? Where does that info come from?

Hi @media_bloke 

"if your module is dependent on another module, you're supposed to reference that other module in the list of <sequence> arguments."

This depends on your requirement or the working of your module let's take and example if you are working related to customer  and you are trying to get customer related data in your module and you didn't mention core customer module in your module.xml. so in some cases your module loads before core customer module and you are not able to get your data in your business logic because core customer module which you didn't use in your custom module load later.

but this scenario happens very rear . So on the conclusion you need to identify which module should be listed in your custom module which depends on your module requirement.   

Hope this helps.
