@graphprotocol/graph-cli

The Graph CLI (graph-cli)

The Graph command line interface.

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

• graph codegen — generates TypeScript code for smart contract ABIs used in subgraphs.
• graph build — compiles subgraphs to WebAssembly and deploys them to IPFS.
• graph deploy — deploys subgraphs to a Graph Node.
• graph remove — removes subgraphs from a Graph Node.
• graph auth — saves access token for Graph Node to the system's keychain.

How It Works

graph takes a subgraph manifest (defaults to subgraph.yaml) with references to

• a GraphQL schema,
• smart contract ABIs,
• mappings written in TypeScript/AssemblyScript.

It compiles the mappings to WebAssembly, builds a ready-to-use version of the subgraph saved to IPFS or a local directory for debugging, and deploys the subgraph to a Graph Node.

Usage

Subgraphs for The Graph are set up like a typical 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.

If you are just getting started with creating a subgraph, head to getting started. Eventually this guide will lead you back here.

For clarity, an example of the setup below can be found in the ENS subgraph repository.

On Linux

libsecret is used for storing access tokens, so you may need to install it before getting started. Use one of the following commands depending on your distribution:

• Debian/Ubuntu: sudo apt-get install libsecret-1-dev
• Red Hat: sudo yum install libsecret-devel
• Arch Linux: sudo pacman -S libsecret

Steps

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 and @graphprotocol/graph-ts dependencies, with one of

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

4. Add the following tsconfig.json:

   {
     "extends": "./node_modules/@graphprotocol/graph-ts/tsconfig.json",
     "compilerOptions": {
       "types": ["@graphprotocol/graph-ts"]
     }
   }
   

5. Add the following to package.json:

   {
     "scripts": {
       "codegen": "graph codegen --output-dir types/",
       "build": "graph build",
       "build-ipfs": "graph build --ipfs /ip4/127.0.0.1/tcp/5001",
       "deploy":
         "graph deploy --ipfs /ip4/127.0.0.1/tcp/5001 --node http://127.0.0.1:8020 --subgraph-name <SUBGRAPH_NAME>"
     }
   }
   

   Note: Replace the IP addresses and ports with any Graph Node you want to deploy the subgraph to.

6. Generate type definitions for contract ABIs used in the subgraph. with:

   yarn codegen
   

   This creates the types/ folder. This folder does not need to be uploaded to GitHub, and the files within it should not be edited.

7. Develop your mapping.ts against these generated types. If you are new to this process, you can head over to getting started for a beginner friendly walkthrough of The Graph.

8. Build the subgraph with:

   yarn build
   

9. Deploy your subgraph to a Graph Node. The following command builds and deploys the subgraph continuously as you are making changes to it:

   graph \
      deploy \
      --watch \
      --verbosity debug \
      --node http://127.0.0.1:8020/ \
      --ipfs /ip4/127.0.0.1/tcp/5001 \
      --subgraph-name <SUBGRAPH_NAME>
   

   Note: If the Graph Node you are deploying to requires authorization, make sure to authorize with the node using e.g. graph auth http://127.0.0.:8020 <ACCESS_TOKEN>` before deploying.

To remove a subgraph from the Graph Node, use:

graph \
  remove \
  --node http://127.0.0.1:8020/ \
  --subgraph-name <SUBGRAPH_NAME>
