Understand the project
Practical overview
When it fits
Use Cleargraph when building an Ethereum dApp or wallet and you need a GraphQL runtime between the application and on-chain smart contracts.
Who it is for
- Developers building Ethereum decentralized applications.
- Developers creating wallet products that need an application API layer for Ethereum.
Documented uses
- Provide a GraphQL runtime as infrastructure for an Ethereum dApp.
- Build a wallet-facing API layer for applications that interact with smart contracts.
- Start the service locally while developing an application.
Before you choose
Requirements & limits
- The project is infrastructure for developers, rather than a standalone wallet or end-user dApp.
- The documented startup process uses Git and Yarn and listens locally on port 4000.
- The repository identifies TypeScript as its primary language and Apache 2.0 as its license.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Source-based practical guide
Clone and start Cleargraph locally
Set up the repository and start the runtime listening on localhost:4000.
Before you start
- Git access to the public dsys/cleargraph repository
- Yarn
Steps
Clone the repository using the documented Git command.
Change into the cleargraph directory.
Install dependencies with yarn install.
Run yarn start to launch the service on localhost:4000.
Expected outcome
The README specifies a local service listening on localhost:4000.
Guide limitations
- The instructions do not describe connecting an application or smart contract to the runtime.
