gethaws's Introduction

Geth Client For AWS Managed Blockchain

Generates RPC clients for regular JSON-RPC clients such as Infura or Alchemy, and for Managed Blockchain which uses a custom authentication mechanism.

Installing

go get github.com/said1296/gethaws

Limitations

Only works for HTTP client, will add support for other client types if people request it.

Usage

In this example the clients are configured loading the configuration from env variables. Further config instructions found at:

https://aws.github.io/aws-sdk-go-v2/docs/configuring-sdk/

You can also pass an aws.Config struct instead of nil to CreateClients in order to use a custom aws.Config.

package main

import (
    "context"
    "github.com/aws/aws-sdk-go-v2/config"
    "net/http"
    "os"
)

func main() {
    err := os.Setenv("AWS_REGION", "us-east-2")
    if err != nil {
        panic(err)
    }
    err = os.Setenv("AWS_ACCESS_KEY_ID", "my_access_key_id")
    if err != nil {
        panic(err)
    }
    err = os.Setenv("AWS_SECRET_ACCESS_KEY", "my_secret_access_key")
    if err != nil {
        panic(err)
    }
    
    // The most common use cases will only use the first returned client, the rpc client is for low level calls not 
    // implemented by geth.
    // The clients can also be created with a manually created aws.Config by passing it instead of nil.
    client, rpcClient, err := gethaws.CreateClients(ctx.Background(), "https://ethereum.managedblockchain/1jsj1i23213nk32mo1", nil)
    if err != nil {
        panic(err)
    }
}
