useGraphqlState

This composable allows you to set fetch options for the useGraphqlQuery, useAsyncGraphqlQuery and useGraphqlMutation composables. One common use case is to pass custom request headers to the GraphQL middleware request:

plugins/graphqlState.ts

export default defineNuxtPlugin({
  name: 'my-state-plugin',
  // Makes sure that your plugin is executed after this plugin.
  // If it were to run before, then `state` would be null.
  dependsOn: ['nuxt-graphql-middleware-provide-state'],
  setup() {
    const state = useGraphqlState()

    // This is nullable because it's injected by a plugin.
    if (!state) {
      return
    }

    // Set fetch options for all GraphQL queries and mutations.
    state.fetchOptions = {
      headers: {
        CustomHeader: 'foobar',
      },
    }
  },
})

You can find more examples in the composables configuration section.
