In this video, you will learn how to use Developer Tools within your browser. I have picked Chrome as an example, but the video is equally applicable to Firefox, Safari and other browsers. I have also picked walmart.com as an example, demonstrating login, add to cart and checkout steps.
What you will learn from this video:
- How to activate Dev Tools within the browser
- How to use the Dev Tools interface
- How to inspect HTTP requests and responses within Dev Tools, and replay them using CURL in your local terminal
- How to inspect application storage (cookies and local storage in particular), and decode JSON Web Tokens (JWTs) using jwt.io
This video is ~20 minutes long, and has been split into two parts. Full screen recommended.
