Type safe Graphql query builder


Write Graphql queries with type validation and auto completion






> [!IMPORTANT]
> Genql is building a cloud platform to automate SDK generation in multiple languages, docs website with examples, changelog website and more.
> Fill [this form](https://tally.so/r/mK1GWM) if you are interested!

Read the [quick start guide](https://genql.dev/docs) to generate your client and start writing queries.

You can stay up to date with the latest changes subscribing to the [Genql changelog](https://changelog.genql.dev).

**Features**

- ✅ Type completion & Type validation
- 🍃 No dependencies (not even graphql)
- ⚡️ [Can easily fetch all scalar fields in a type](https://genql.dev/docs/usage/fetch-all-fields-on-a-type)
- 🐎 [Works with any client (Apollo, Relay, etc)](https://genql.dev/docs/usage/integrate-with-other-graphql-clients)
- 🥃 [Support for Subscriptions](https://genql.dev/docs/usage/subscriptions)
- 🔋 [Built in batching support](https://genql.dev/docs/usage/batching-queries)
- ↔️ [Easy migrate existing GraphQL queries to Genql code](https://genql.dev/converter)
- 🚂 Works in browser, Node, Deno, Cloudflare workers, Bun and more

## Example

First generate your client with the `genql` cli.

> You can find other cli options [here](https://genql.dev/docs/cli-reference)

```sh
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

```js
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

```graphql
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
