apollo-link-prismic

Purpose

An Apollo Link that allow you query Prismic's GraphQL API with apollo-client.

Installation

npm install apollo-link-prismic

Usage

import { ApolloClient, InMemoryCache } from "@apollo/client";
import { createPrismicLink } from "apollo-link-prismic";

const apolloClient = new ApolloClient({
	link: createPrismicLink({
		repositoryName: "YOUR_REPOSITORY_NAME",
		// Provide your access token if your repository is secured.
		accessToken: "YOUR_ACCESS_TOKEN",
	}),
	cache: new InMemoryCache(),
});

Providing a fetch function

If you are using this link in an environment where a global fetch function does not exist, such as Node.js, you must provide one using the fetch option.

Environments like the browser, Next.js, Cloudflare Workers, and Remix provide a global fetch function and do not require passing your own.

There are many libraries that can provide this function. The most common is node-fetch, which you would configure like this:

import { ApolloClient, InMemoryCache } from "@apollo/client";
import { createPrismicLink } from "apollo-link-prismic";
import fetch from "node-fetch";

const apolloClient = new ApolloClient({
	link: createPrismicLink({
		repositoryName: "YOUR_REPOSITORY_NAME",
		// Provide your access token if your repository is secured.
		accessToken: "YOUR_ACCESS_TOKEN",
		fetch,
	}),
	cache: new InMemoryCache(),
});

Installation with React Native

Using apollo-link-prismic in React Native applications requires additional setup.

After installing apollo-link-prismic, install the following URL Web API polyfill:

npm install react-native-url-polyfill

Next, import the polyfill in your app’s entry file (typically this is App.js or index.js).

// App.js or index.js

import "react-native-url-polyfill/auto";

apollo-link-prismic can now be used throughout your app.

Note: If the polyfill does not work after importing in your app's entry file, try the alternative "Flexible" set up method described in react-native-url-polyfill's documentation.
