@graphprotocol/graph-cli

The Graph CLI (graph-cli)

The Graph command line interface.

As of today, the command line interface consists of two commands:

• graph codegen — generates TypeScript code for smart contract ABIs used in subgraphs.
• graph build — compiles subgraphs to WebAssembly and deploys them to IPFS.

How It Works

graph takes a subgraph.yaml subgraph manifest with

• references to a GraphQL schema,
• smart contract ABIs, and
• mappings written in TypeScript/AssemblyScript,

compiles the mappings to WebAssembly and deploys a ready-to-use version of the subgraph to IPFS or a local directory for debugging.

Usage

Subgraphs for The Graph are set up just like any regular TypeScript project. It is recommended to install graph-cli as a local dependency via package.json and use npm scripts for code generation and building.

An example of this can be found in the Decentraland repository.

1. Create a project for the subgraph with a package.json etc.
2. Add a subgraph.yaml subgraph manifest with a GraphQL schema etc.
3. Add @graphprotocol/graph-cli as a local dependency with one of

   npm install --save-dev @graphprotocol/graph-cli # NPM
   yarn add --dev @graphprotocol/graph-cli         # Yarn
   

4. Add the following tsconfig.json:

   {
     "extends": "./node_modules/graph-cli/tsconfig.json",
     "files": ["mapping.ts"]
   }
   

   Note: Replace "mapping.ts" with your own mapping fil(e)s.
5. Add the following to package.json:

   {
     "scripts": {
       "codegen": "graph generate-types subgraph.yaml",
       "build": "graph build subgraph.yaml",
       "build-ipfs": "graph build --ipfs /ip4/127.0.0.1/tcp/5001 subgraph.yaml"
     }
   }
   

   Note: Replace the IPFS address with any IPFS node you want to deploy the subgraph to.
6. Generate type definitions for contract ABIs used in the subgraph with:

   yarn codegen
   

7. Develop your mapping.ts against these generated types.
8. Build the subgraph with one of

   yarn build      # Will drop the results in dist/
   yarn build-ipfs # Will also deploy to IPFS and output an IPFS hash
