Example

First generate your client with the genql cli.

You can find other cli options here

npm i -D @genql/cli # cli to generate the client code
genql --schema ./schema.graphql --output ./generated

Then you can use your client as follow

import { createClient, everything } from './generated'
const client = createClient()

client
    .query({
        countries: {
            // pass arguments to the query
            __args: {
                filter: {
                    currency: {
                        eq: 'EUR',
                    },
                },
            },
            name: true,
            code: true,
            nestedField: {
                // fetch all scalar fields
                __scalar: true,
            },
        },
    })
    .then(console.log)

The code above will fetch the graphql query below

query {
    countries(filter: { currency: { eq: "EUR" } }) {
        name
        code
        nestedField {
            scalarField1
            scalarField2
        }
    }
}

Why

Genql has a lot of benefits over writing graphql queries by hand:

• Writing queries is faster thanks to TypeScript auto completion
• You can safely update your schema and be sure your queries are still valid
• You can fetch all scalar fields in a type with __scalar: true
• No graphql package dependency, no runtime parsing of queries
• You have to generate the client only after your schema changes, not after every query change
