📣 ESLint rules: how to begin implementing one

Implementing an ESLint rule might seem mystical and cryptic at first glance. I believe that shouldn't be the case, though! My goal is to demystify the process of implementing a custom ESLint rule.
I will begin by explaining fundamentals of AST parsing (it sounds much more scary than it is). Followed by a live coding session where I will implement a simple ESLint rule and cover it with tests. Live coding will be the largest part of the presentation.
Perfect for: developers who are interested, curious about ESLint, developers who want to start contributing to open-source - ESLint plugins have lots of open issues and it's relatively easy to start contributing.

👨‍💻 Bio: Tomas Zaicevas

Frontend Developer at Vinted. I like to dive deep into React, testing and ESLint. You can find me writing about these topics on my blog.
I've contributed to multiple ESLint plugins, including open-source (eslint-plugin-testing-library, eslint-plugin-unicorn) and internally @Vinted.
I've been playing accordion since age 8 and you can still hear me playing on rare occasions. Fun fact: I had a concert in China.
