The are required to prepare subgraphs and interact with the graph node.
Install them with npm:
npm install --save @graphprotocol/graph-cli
Deploying the subgraph is a multi-step process:
codegen generates AssemblyScript types from the subgraph's GraphQL schema and the contract ABIs included in the data sources. It must be run when either the schema or ABIs change.
build generates the AssemblyScript from the subgraph's indexing scripts.
graph create generates the namespace on the node where all the subgraph data will be stored. It must only be run once.
graph deploy uploads the subgraph package to IPFS and instructs the graph node to use it.

graph create with example output
The create command needs to know the service URL of your Graph Node, which is http://127.0.0.1:8020 in the default setup:
› Warning: In next major version, this command will be merged as a subcommand for `graph local`.
Created subgraph: vebetterdao/tokens
graph deploy with example output
The deploy command needs to know the service URL, the IPFS node to upload the subgraph package and the subgraph definition to upload. In the default setup, the service URL is http://127.0.0.1:8020 and the IPFS node is available on http://127.0.0.1:5001.
The previously generated vebetterdao/tokens.subgraph.yaml is the subgraph definition to upload. A version is required and is used to identify different deployments. In the local environment, versions can be ignored and re-used.
