graphql-ethereum-address

Ethereum address scalar types for GraphQL

Quickstart

Install with yarn:

yarn add graphql-ethereum-address

Install with npm:

npm install graphql-ethereum-address

Integration to your existing GraphQL Schema

You need to add a scalar definition to your SDL type definitions and resolvers like below:

In your SDL type definitions

scalar EthereumAddress

You can also import ready-to-use type definitions like below:

import { EthereumAddressTypeDefinition } from 'graphql-ethereum-address';

const typeDefs = [
  EthereumAddressTypeDefinition,
  // other typeDefs
];

In your resolver map

import { EthereumAddressResolver } from 'graphql-ethereum-address';

const myResolverMap = {
  EthereumAddress: EthereumAddressResolver,

  Query: {
    // more stuff here
  },

  Mutation: {
    // more stuff here
  },
};

Using it in your type definitions

That's it. Now you can use the scalar type in your schema definition like this:

type Wallet {
  id: String
  address: EthereumAddress
}

With Nexus

import { asNexusMethod } from 'nexus';
import { makeSchema } from 'nexus';
import { EthereumAddressResolver } from 'graphql-ethereum-address';

const EthereumAddressScalar = asNexusMethod(EthereumAddressResolver, 'eth');

export const Wallet = objectType({
  name: 'Wallet',
  definition(t) {
    t.string('id');
    t.eth('address');
  },
});

const schema = makeSchema({ types: [EthereumAddressScalar, Wallet] });
