Block Stats Subgraph

This is a composed subgraph that combines and aggregates the information from the 3 source subgraphs.

To keep this example as simple as possible, all source subgraphs use only block handlers, but in a real environment each source subgraph will use data from different smart contracts.

Note

Any change to a source subgraph will most likely generate a new deployment ID. Be sure to update the deployment ID in the data source address of the subgraph manifest to take advantage of the latest changes.

Local Deployment

Requirements

These are minimal requirements to deploy this subgraph locally:

• A graph-node instance running locally
• An IPFS instance running locally
• Node.js and npm

Deployment

Important

All source subgraphs should be deployed before the composed subgraph is deployed.

To deploy this subgraph locally, run the following commands:

npm install
npm run codegen
npm run build
npm run create-local
npm run deploy-local
