Nhost golang client SDK - WIP

This is a port of the Nhost JavaScript SDK to golang. The plan is to provide the same functionality as the JS SDK but for projects using golang.

Basic usage:

package main

import (
  "fmt"
  "github.com/beepshow/nhost-go/hasura_auth"
  "github.com/beepshow/nhost-go/nhost"
)

func main() { 
  // Assume nhost running locally. For remote specify the correct subdomain and region. 
  nhostClient, err := nhost.New("localhost", "")
  if err != nil {
    panic(err)
  }

  // Auth token will be updated
  nhostClient.Auth.OnTokenChanged(func(session *hasura_auth.Session) {
    if session == nil {
      fmt.Printf("Session ended\n")
    } else {
      fmt.Printf("Updated access token: %s\n", session.AccessToken)
    }
  })

  // Force token refresh every 5 seconds
  nhostClient.Auth.RefreshIntervalTime = 5

  // Sign in nhost user [email protected]
  signInRes := nhostClient.Auth.SignInEmailPassword(hasura_auth.SignInEmailPasswordParams{
    Email:    "[email protected]",
    Password: "s3cr3t",
  })
  if signInRes.Error != nil {
    panic(signInRes.Error.Message)
  }

  // Just keep running to have the token change function called
  select {}
}

Implemented features:

• NhostClient providing access to Auth, Storage (and later Graphql and Functions) clients
• Auth client
  • Sign in with email/password (nhostClient.Auth.SignInEmailPassword())
  • Sign out (nhostClient.Auth.SignOut()
  • Callbacks on token change (nhostClient.Auth.OnTokenChanged()) and auth status change (nhostClientAuth.OnAuthStateChanged())
• Storage client
  • Automatic update of access token when Auth refreshes token
  • Get presigned URL for downloading files (nhostClient.Storage.GetPresignedUrl())
