Know you heroes! 😉

👇🏻👇🏻👇🏻

In 2019, I met a person who was doing bug bounty playfully. At that moment, it seemed like some kind of complicated process to me. How can you find something faster than everyone else?!
In the process of communication, in June 2019, we dragged a $12,600 bug into PayPal, and suddenly the understanding came: it seems that I can really do something.

Almost 6 years later, I've gotten my profile to 12k Reputation - while completely ignoring reputation mining through free reports. I always thought it was a weird thing to do.
Time flew by incredibly fast. At that time it seemed to me that it was almost impossible to send so much rep, so many valid reports, to be noticed in the community. I hope there is still a lot of interesting things ahead 😉 The next milestone will be Top100 Hackerone. 🤞

⚒️ Async & Sync Cheat Sheet Angular 🛠

👉 No reactivity + non-reactive DOM
- afterNextRender()

👉 No reactivity + plain read
- signal()

👉 Streams
- RxJS Observable

👉 Signals, sync derivation:
- Writable: signal()
For local, mutable state

- Read-only: computed()
For derived, read-only state

- Writable derived: linkedSignal()
Derived signal that is also writable

👉 Signals, async derivation
- Promise: resource()
For async operations returning a Promise
( only GET )

- Observable: rxResource()
For async data from an Observable
( only GET )

- HttpClient: httpResource()
( only GET )

Mutations to handle
POST, PATCH, PUT, DELETE
are missing for now

👉 Side Effects on sync APIs
- afterRenderEffect()
Runs an effect after app rendered

- effect()
Runs before component sync

#angular #signals
