# Experiment Go
|
|
|
|
There come a time when you need to experiment new things, new style, new approach.
|
|
So this post serves as it is named.

# Design API by trimming down the interface/struct or whatever
|
|
|
|
Instead of:
|
|
|
|
```go
|
|
type Client interface {
|
|
GetUser()
|
|
AddUser()
|
|
GetAccount()
|
|
RemoveAccount()
|
|
}
|
|
|
|
// c is Client
|
|
c.GetUser()
|
|
c.RemoveAccount()
|
|
```
|
|
|
|
Try:
|
|
|
|
```go
|
|
type Client struct {
|
|
User ClientUser
|
|
Account ClientAccount
|
|
}
|
|
|
|
type ClientUser interface {
|
|
Get()
|
|
Add()
|
|
}
|
|
|
|
type ClientAccount interface {
|
|
Get()
|
|
Remove()
|
|
}
|
|
|
|
// c is Client
|
|
c.User.Get()
|
|
c.Account.Remove()
|
|
```
|
|
|
|
The difference is `c.GetUser()` -> `c.User.Get()`.
|
|
|
|
For example we have client which connect to bank.
|
|
There are many functions like `GetUser`, `GetTransaction`, `VerifyAccount`, ...
|
|
So split big client to many children, each child handle single aspect, like user or transaction.
|
|
|
|
My concert is we replace an interface with a struct which contains multiple interfaces aka children.
|
|
I don't know if this is the right call.
|
|
|
|
This pattern is used by [google/go-github](https://github.com/google/go-github).

## Find alternative to [grpc/grpc-go](https://github.com/grpc/grpc-go)
|
|
|
|
Why?
|
|
[See for yourself](https://github.com/grpc/grpc-go/issues?q=is%3Aissue+compatibility+is%3Aclosed).

Currently there are some:
|
|
|
|
- [bufbuild/connect-go](https://github.com/bufbuild/connect-go). Comming from buf, trust worthy but need time to make it match feature parity with grpc-go.
