gql..mjs.module entry for tree shaking bundlers.id fields.__typename insertion.Install with npm:
npm install graphql-react
Create and provide a GraphQL client:
import { GraphQL, Provider } from 'graphql-react'
const graphql = new GraphQL()
const Page = () => (
<Provider value={graphql}>Use Consumer or Query components…</Provider>
)
See the example GraphQL API and Next.js web app, deployed at graphql-react.now.sh.
Consider polyfilling:
A lightweight GraphQL client that caches requests.
Parameters
options Object Options. (optional, default {})
options.cache Object Cache to import; usually from a server side render. (optional, default {})Examples
import { GraphQL } from 'graphql-react'
const graphql = new GraphQL()
GraphQL request cache map, keyed by fetch options hashes.
Type: Object<string, RequestCache>
Examples
Export cache as JSON.
const exportedCache = JSON.stringify(graphql.cache)
Queries a GraphQL server.
Parameters
options Object Options.
options.operation Operation GraphQL operation object.options.fetchOptionsOverride FetchOptionsOverride? Overrides default GraphQL request fetch options.options.resetOnLoad boolean Should the GraphQL cache reset when the query loads. (optional, default false)Returns ActiveQuery Loading query details.
Resets the GraphQL cache. Useful when a user logs out.
Parameters
exceptFetchOptionsHash string? A fetch options hash to exempt a request from cache deletion. Useful for resetting cache after a mutation, preserving the mutation cache.Examples
graphql.reset()
A React component provides a GraphQL instance in context for nested Consumer components to use.
Parameters
Examples
import { GraphQL, Provider } from 'graphql-react'
const graphql = new GraphQL()
const Page = () => (
<Provider value={graphql}>Use Consumer or Query components…</Provider>
)
Returns ReactElement React virtual DOM element.
A React component that gets the GraphQL instance from context.
Parameters
children ConsumerRender Render function that receives a GraphQL instance.Examples
A button component that resets the GraphQL cache.
import { Consumer } from 'graphql-react'
const ResetCacheButton = () => (
<Consumer>
{graphql => <button onClick={graphql.reset}>Reset cache</button>}
</Consumer>
)
Returns ReactElement React virtual DOM element.

(optional, default false)props.loadOnReset boolean Should the query load when the GraphQL cache is reset. (optional, default false)props.resetOnLoad boolean Should the GraphQL cache reset when the query loads. (optional, default false)props.children QueryRender Renders the query status.Examples

await preload(page)
return {
cache: JSON.stringify(graphql.cache),
