Introduction#

From previously working on a large GraphQL codebase, the boilerplate involved with shipping new features often slowed me down.

What is#

gqty is a fundamentally new approach to a GraphQL client. It makes using your API enjoyable, by generating queries at runtime based upon the data your app consumes.

Your app#

const App = () => {
  const query = useQuery();

  return (
    <div>
      Hello {query.me.name}!
      {query.users({ limit: 10 }).map((user) => (
        <User key={user.id || 0} user={user} />
      ))}
    </div>
  );
};

Generated query#

query {
  me {
    name
  }
  users(limit: 10) {
    id
    name
  }
}

Why#

I wanted a GraphQL client that lets you forget you're using GraphQL, whilst tackling some issues shared across all existing GraphQL clients:

Slow Typescript DX. Typescript should speed up your workflow, not slow it down
Inefficient queries, due to underutilized nesting. Relay is a solution, but has even more boilerplate 😢

Workflow comparison#

Lets say you've just added a new field to your API, and want it displayed within multiple places in the UI:

type User {
  username: String!
+ avatarUrl(size: Int!): String!
}

Conventional client#

First you'd need to search your components, and identify which queries need updating. After referring to your browser for documentation, you'd then update the query

query UserProfile(avatarSize: Int!) {
  user {
    ...
+   avatarUrl(size: $avatarSize)
  }
}

Typically you'd then run a type generator to create types for each query (changes may not be reflected in IDE straight away).

Finally you'd do the task you set out to do - updating the components,

const UserProfile = ({ id }) => {
  const { data } = useQuery(
    gql`
      query UserProfile($username: ID!, $avatarSize: Int!) {
        user(username: $id) {
          avatarUrl(size: $avatarSize)
        }
      }
    `,
    {
      variables: { id, avatarSize: 100 },
    }
  );

  return <img src={data.user.avatarUrl} />;
};

With GQty#

Just update your components, and the queries generated at runtime will reflect your changes.

const UserProfile = ({ id }) => {
  const query = useQuery();
  return <img src={query.user({ id }).avatarUrl({ size: 100 })} />;
};
