Defined SDK

This package exists to help you develop on top of the Defined API (https://docs.defined.fi).

It provides the public schema SDL for you to use. You can use graphql-codegen to generate types and queries for example.

Installation

Usage

Follow one of the examples in the examples directory, or simply run.

Fetch a token.

import { Defined } from "@definedfi/sdk";

const sdk = new Defined(MY_API_KEY);

sdk.queries
  .token({
    input: {
      address: "0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c",
      networkId: 56,
    },
  })
  .then(console.log);

Use your own GraphQL selections

import { Network } from "../../src/resources/graphql";
import { Defined } from "@definedfi/sdk/dist/sdk";

const sdk = new Defined(process.env.DEFINED_API_KEY || "");

sdk
  .send<{ getNetworks: Network[] }>(
    `
  query GetNetworks {
    getNetworks { id name }
  }
`,
    {}
  )
  .then((res) => {
    console.log("Networks: ", res.getNetworks);
  });

Running the examples

You'll need to have curl installed in order to build this locally, as it fetches the schema from the Defined API.

You need to provide an API key in order for the examples to work. We have bun in use for development here.

After installing bun, from the project root.

• bun i
• bun run build

Simple

This performs a simple inline graphql request, and uses a user-provided query and selection set.

• cd examples/simple
• bun i
• DEFINED_API_KEY=xyz bun run index.ts

You can define your own GraphQL queries and use those with codegen (see next section). The pre-defined queries we provide in the examples do not include all of the fields for every query.

Codegen

This shows how to use graphql-codegen to generate query types and get a fully typed end-to-end experience.

• cd examples/codegen
• bun i
• bun run codegen
• DEFINED_API_KEY=xyz bun run src/index.ts

Next

This shows how you could use it in a NextJS project.

• cd examples/next
• bun i
• NEXT_PUBLIC_DEFINED_API_KEY=xyz bun run dev
