Job switch prepration strategy

Brief about me - I have around a year of experience working as a Frontend developer, primarily with ReactJS.

Its been some time since I touched the basics and tbh I've not given time to it earlier also (i switched fields and prepare in around 8 months mostly doing DSA and Frontend development)

I am looking for advice to for the preparation strategy to move to new job, I am looking for roles in frontend/Full stack development.

Please tell me the essentials I should have under my bag and some of the things to give my resume an edge

Thank you.
