## Highlights

- Most **simple & lightweight** GraphQL client
- Promise-based API (works with `async` / `await`)
- ESM native package (CJS build is included for now as well, but will eventually be removed)
- First class TypeScript support
  - Including `TypedDocumentNode`
- Isomorphic (works in both Nodejs and Browsers)

## Install

```sh
npm add graphql-request graphql
```

## Quick Start

Send a GraphQL document using a static request function:

```js
import { request, gql } from 'graphql-request'

const document = gql`
  {
    company {
      ceo
    }
  }
`
await request('https://api.spacex.land/graphql/', document)
```

The function can be passed a configuration object for more complex cases:

```ts
await request({
  url,
  document,
  variables,
  requestHeaders,
})
```

A class is available for constructing your own instances:

```js
import { GraphQLClient } from 'graphql-request'

const document = gql`
  {
    company {
      ceo
    }
  }
`
const client = new GraphQLClient(endpoint)
await request('https://api.spacex.land/graphql/', document)
```

## Node Version Support

We only (officially) support [versions of Nodejs](https://github.com/nodejs/Release#release-schedule) of the following status:

- Current
- LTS
- Maintenance _and end of life not yet reached_

So for example on May 1 2023 that would mean these versions: 16, 18, 19.

Any issue that exists solely for an unsupported version of Nodejs will be rejected (not worked on).

## Reference

⚠️ This reference is incomplete. Check out the [examples](./examples/) for more reference material.

### Configuration

#### ErrorPolicy

By default GraphQLClient will throw when an error is received. However, sometimes you still want to resolve the (partial) data you received.
You can define `errorPolicy` in the `GraphQLClient` constructor.

```ts
const client = new GraphQLClient(endpoint, { errorPolicy: 'all' })
```

##### None (default)

Allow no errors at all. If you receive a GraphQL error the client will throw.

##### Ignore

Ignore incoming errors and resolve like no errors occurred

##### All

Return both the errors and data, only works with `rawRequest`.

## Knowledge Base

#### Why was the file upload feature taken away? Will it return?

In [this issue](https://github.com/jasonkuhrt/graphql-request/issues/500) we decided to make this library more stable and maintainable. In principal the feature is still in scope of this library and will make a return when we find time to do the feature right.

#### Why do I have to install `graphql`?

`graphql-request` uses methods exposed by the `graphql` package to handle some internal logic. On top of that, for TypeScript users, some types are used from the `graphql` package to provide better typings.

#### Do I need to wrap my GraphQL documents inside the `gql` template exported by `graphql-request`?

No. It is there for convenience so that you can get the tooling support like prettier formatting and IDE syntax highlighting. You can use `gql` from `graphql-tag` if you need it for some reason too.

#### What sets `graphql-request` apart from other clients like Apollo, Relay, etc.?

`graphql-request` is the most minimal and simplest to use GraphQL client. It's perfect for small scripts or simple apps.

Compared to GraphQL clients like Apollo or Relay, `graphql-request` doesn't have a built-in cache and has no integrations for frontend frameworks. The goal is to keep the package and API as minimal as possible.
