In 2020 most of my time was spent dealing with legacy systems revolving around jQuery. By the end of the year, I had my personal roadmap quite laid out for 2021, and migration to react is on top of the list.

I started listing down the things I have to do:

• list the new feature requirements
• check my current reactJS setup
• review reactJS changes and the packages I use

Current setup: reactJS + redux. To note, I'm using redux-form and redux-saga. I use this for my big dashboard projects.

New setup: reactJS, no redux. My new project does not need redux. I'm still in the process of redesigning, but this will probably be it. I will surely miss redux-saga though.

Anyway, for now here are things I learned / checked out:

• new form: formik vs react-final-form. I learned both and their APIs do look similar.
• validations: yup. Clean validation schemas. I haven't looked for something else though. So no comparisons.
• xhr: ky. Based on the native fetch.
• react-query. Interesting, especially for data-heavy projects.
• new setup for webpack5 and babel
• enzyme vs react-testing-library. Decided not to change my current setup using enzyme. At least not for now, because I just have too many other things to decide on.
• Learned redux-saga can be used without redux

Lastly, Robin Wieruch's tutorials. I first started truly learning reactJS through his ebooks. That was in 2017. Every time I want to brush up on my FE knowledge, I always visit his website.
