4/ Tradeoffs to consider:
Cached data can be stale → must handle expiration
Memory/storage costs
Complexity in cache invalidation
Not all data is worth caching
REST vs GraphQL — The Only Thread You Need 🧵
1/ If you build APIs, you’ve heard this debate: REST vs GraphQL.
Both solve the same problem: letting clients talk to servers.
But they do it very differently.
Let’s break it down in the most practical way possible.
Without HTTPS:
• Passwords could be intercepted
• Payment info could be stolen
• Data could be altered in transit
HTTPS is the foundation of backend security.
Every secure system starts here.
What is HTTPS and why does every website use it? 🔐
When you open a website, your browser talks to a server.
That communication needs to be secure — especially for passwords, payments, and personal data.
That’s where HTTPS comes in 👇
HTTPS = HyperText Transfer Protocol Secure
It does 3 main things:
1️⃣ Encrypts data (so hackers can’t read it)
2️⃣ Verifies the server (so you know it’s legit)
3️⃣ Protects data integrity (so it isn’t modified in transit)
It uses SSL/TLS encryption to make this happen 🔒
