Goldsky from Go, Without the Glue Code: Introducing goldsky-go

The provided documentation outlines the features and capabilities of a Go client library for Goldsky, an Ethereum data platform. Here's a summary of its key functionalities:

1. GraphQL Client:

   • The library provides support for both public and private GraphQL queries.
   • It includes functionality to handle errors returned by the server in a structured manner (e.g., graphQLError.Message).
   • Example usage shows how to query metadata about indexed blocks.

2. JSON-RPC Support:

   • The client supports HTTPS JSON-RPC 2.0, including batch calls.
   • It sends the Edge key via an HTTP header (X-ERPC-Secret-Token) rather than in the URL or endpoint.
   • Example usage demonstrates how to call eth_blockNumber and handle responses.

3. Error Handling:

   • REST errors are represented using RFC 9457 problem details, allowing for stable error types and status helpers.
   • The library provides utilities like goldsky.AsProblem() to parse and categorize errors based on their type (e.g., problem.IsNotFound()).
