I saw this recently.
If you need to get any book on the internet, type the name of the book followed by “doctype:pdf” and you’ll get the book in pdf format
For example, Purple Hibiscus doctype:pdf
Please load test your API before going live.
Load testing is just the ability of your system to handle expected and peak traffic by simulating real-world usage, helping you understand how it behaves under stress, where it breaks, and how it scales.
These are 3 good load testing tools:
k6
Apache JMeter
Locust
These would save you a whole bunch of production issues once your user base starts growing.
Your website stores JWT tokens in localStorage.
A malicious script steals the token and logs in as the user.
How is this possible and how do you prevent it?
A Nigerian fintech startup lost ₦47 million in one night.
Not to hackers. Not to fraud.
To one missing line of code.
Every backend dev in Nigeria needs to see this
The story I started with ended well.
Once they moved away from localStorage token storage and redesigned their authentication flow, the account hijacking stopped.
But the lesson stayed with them.
Authentication systems aren’t just about logging users in.
They are about protecting user identity across every request your system receives.
Tomorrow we’ll go deeper into production authentication systems, including the edge cases that break most implementations.
Worth revisiting if you build backend systems.
