@genql/cli

Type safe Graphql query builder

Write Graphql queries with type validation and auto completion

Read the quick start guide to generate your client and start writing queries.

You can stay up to date with the latest changes subscribing to the Genql changelog.

🔥 Features

• Type completion & Type validation
• No dependencies
• Easily fetch all scalar fields in a type
• Works with any client (Apollo, Relay, etc)
• Works in browser, Node, Deno, Cloudflare workers, Bun and more

Example

First generate your client executing

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 other 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
• You have to generate the client only after your schema changes, not after every query change
