ELI5: Explain Like I'm 5

Canonical protocol pattern

Okay kiddo, imagine you have a box of crayons with different colors. Sometimes you want to use a specific crayon, like red, but other times you want to use a color that's not in the box, like pink.

In the computer world, there are also programs that need to communicate with each other. Sometimes, they use the same language and everything works fine. Other times, they might not have the right language to talk to each other.

That's where the canonical protocol pattern comes in. It's like having a special translator who can make sure that everyone understands each other, no matter what language they speak.

The idea is to create a standard way of communicating between programs, like a set of rules that everyone agrees to follow. This way, if one program needs to send information to another, it can do so in a way that both programs understand.

Just like how you might need a special crayon to draw something specific, sometimes programs might need to use a special way of communicating to get the job done. And with the canonical protocol pattern, they can make sure they're speaking the same language.
