This repo is currently in its Proof of Concept stages.
ethql is a server that exposes a GraphQL endpoint to the public Ethereum ledger. It works against the standard JSON-RPC APIs offered by all Ethereum clients. It is built in TypeScript, and thus leverages the vast ecosystem of GraphQL tooling while preserving compile-time type safety.
ethql regards blockchain data as a graph, and leverages the extensibility of GraphQL to introduce additional functionality, amongst which are:
- Decoding of standard transactions (e.g. ERC20, ENS, ERC223, etc.) out of the box.
- New query patterns enabled by indexing solutions (e.g. all transactions between any two accounts).
- Automatic batching and caching of requests.
- New filtering capabilities.
- Simple, inline unit conversions.
- Enhancing public data with informaton overlays imported from other sources.
This project is in the experimental phase, and all the cited features are under heavy development.
You need a running Node environment with at least:
- nodejs >= 8.0.0
- yarn
Clone the repo and run:
$ yarn install
$ npm run dev
Running a GraphQL API server at http://localhost:4000/graphql
This ethql server uses Infura as a backend in anonymous mode. If you have an Infura ID (and if you don't, you should sign up for one!) you can set it like this:
$ INFURA_ID=myid npm run dev
