The Graph is an indexing protocol for querying networks like Ethereum and IPFS. Our subgraphs allow you to get data from the Semaphore.sol smart contract.

🛠 Install

Clone this repository:

git clone https://github.com/semaphore-protocol/subgraph.git

and install the dependencies:

cd subgraph && yarn

Usage

The subgraph definition consists of a few files:

• subgraph.template.yaml: a YAML file containing the subgraph manifest,
• schema.graphql: a GraphQL schema that defines what data is stored for the subgraph, and how to query it via GraphQL,
• src/mappings.ts: AssemblyScript code that translates from the event data to the entities defined in the schema.

Code quality and formatting

Run ESLint to analyze the code and catch bugs:

yarn lint

Run Prettier to check formatting rules:

yarn prettier

or to automatically format the code:

yarn prettier:write

Code generation

Generate AssemblyScript types for the subgraph (required every time the schema changes):

yarn codegen

Authorization

Set the authorisation code that links your account on thegraph.com:

yarn auth <access-token>

Deploy

Deploy the subgraph to the hosted service:

yarn deploy:kovan
// or
yarn deploy:goerli
// or
yarn deploy:arbitrum
