PRINCIPLE
A class should have one, and only one reason to change.
Good Package Names
net/http encoding/json os/exec
Bad Package Names
server helpers ctrls
OPEN CLOSE PRINCIPLE
Software entites should be open for extension, closed for modification
LISKOV SUBSTITUTION PRINCIPLE
Two types of substitutable, if they exhibit behavior such the caller is unable to tell the difference
INTERFACES
Small Interfaces, Simple implementations.
INTERFACES
type Reader interface {
Read(p []byte) (n int, err error)
}
INTERFACE SEGREGATION PRINCIPLE
Clients should not be dependent on methods that they don't use
DEPENDENCY INVERSION PRINCIPLE
High level modules should not depend on low level modules, both should depend on abstractions.
