Introduction to Subgraph Development
To start coding right away, go to Developer Quick Start.
Overview
As a developer, you need data to build and power your dapp. Querying and indexing blockchain data is challenging, but The Graph provides a solution to this issue.
On The Graph, you can:
- Create, deploy, and publish Subgraphs to The Graph using Graph CLI and Subgraph Studio.
- Use GraphQL to query existing Subgraphs.
What is GraphQL?
- GraphQL is the query language for APIs and a runtime for executing those queries with your existing data. The Graph uses GraphQL to query Subgraphs.
Developer Actions
- Query Subgraphs built by other developers in The Graph Network and integrate them into your own dapps.
- Create custom Subgraphs to fulfill specific data needs, allowing improved scalability and flexibility for other developers.
- Deploy, publish and signal your Subgraphs within The Graph Network.
What are Subgraphs?
A Subgraph is a custom API built on blockchain data. It extracts data from a blockchain, processes it, and stores it so that it can be easily queried via GraphQL.
