With the new Web3.js 2.0 comes a brand-new client-side GraphQL resolver for the Solana JSON RPC.
This GraphQL library:
- Allows developers to make requests to the Solana JSON RPC using GraphQL queries.
- Provides a full type schema around Solana's
jsonParsedtype spec. - Offers highly-optimized usage of RPC requests out of the box.
- Supports the Relay server specification, enabling Relay-native web applications.
Provided here for demonstration is a web application - a basic, read-only wallet and block explorer - that aims to showcase the GraphQL library's capabilities.
Requirements:
- NodeJS 20
- NPM
- PNPM
- Rust

cargo-install shank-cli - Solana 1.18:
