fusion-plugin-apollo

Fusion.js plugin for universal rendering with React and Apollo

This package provides universal rendering for Fusion.js applications leveraging GraphQL.

The plugin will perform graphql queries on the server, thereby rendering your applications initial HTML view on the server before sending it to the client. Additionally this plugin will also provide initial state hydration on the client side.

Installation

yarn add fusion-plugin-apollo

Usage

// ./src/main.js
import React from 'react';
import App from 'fusion-react';
import {RenderToken} from 'fusion-core';

import {
  ApolloRenderEnhancer,
  ApolloClientPlugin,
  ApolloClientToken,
  GraphQLSchemaToken, 
} from 'fusion-plugin-apollo';

export default function() {
  const app = new App(<Hello />);
  app.enhance(RenderToken, ApolloRenderEnhancer);
  app.register(ApolloClientToken, ApolloClientPlugin);
  if (__NODE__) {
    app.register(GraphQLSchemaToken, YourGraphQLSchema);
  }
  return app;
}

Usage with external server

When schema file is not provided, the plugin will not run graphQL server locally. The endpoint of the external graphQL server can be then provided using GraphQLEndpointToken.

// ./src/main.js
import React from 'react';
import App from 'fusion-react';
import {RenderToken} from 'fusion-core';

import {
  ApolloRenderEnhancer,
  ApolloClientPlugin,
  ApolloClientToken,
  GraphQLSchemaToken, 
} from 'fusion-plugin-apollo';

export default function() {
  const app = new App(<Hello />);
  app.enhance(RenderToken, ApolloRenderEnhancer);
  app.register(ApolloClientToken, ApolloClientPlugin);
  app.register(GraphQLEndpointToken, 'http://website.com/graphql');
  return app;
}

Loading GraphQL Queries/Schemas

fusion-plugin-apollo ships with a compiler plugin that lets you load graphql queries and schemas with the gql macro. This macro takes a relative path argument and returns the query/schema as a string.

NOTE: Because this is a build time feature, the path argument must be a string literal. Dynamic paths are not supported.

import {gql} from 'fusion-plugin-apollo';
const query = gql('./some-query.graphql');
const schema = gql('./some-schema.graphql');

API

Registration API

ApolloClientToken

import {ApolloClientToken} from 'fusion-plugin-apollo';

A plugin, which provides an instance of Apollo Client, to be registered and used as within the Apollo Provider. You can use fusion-apollo-universal-client as a barebones Apollo Client token.

type ApolloClient<TInitialState> = (ctx: Context, initialState: TInitialState) => ApolloClientType;

ApolloContextToken

import {ApolloContextToken} from 'fusion-plugin-apollo';

Optional - A function which returns the apollo context. Defaults to the fusion context. See the Apollo Client context documentation for more details.

type ApolloContext<T> = (ctx: Context => T) | T;

GraphQLSchemaToken

import {GraphQLSchemaToken} from 'fusion-plugin-apollo';

Your graphql schema is registered on the GraphQLSchemaToken token. This is the result of makeExecutableSchema or makeRemoteExecutableSchema from the graphql-tools library.

GraphQLEndpointToken

import {GraphQLEndpointToken} from 'fusion-plugin-apollo';

Optional - the endpoint for serving the graphql API. Defaults to '/graphql'. This can also be an endpoint of an external graphQL server (hosted outside fusion app).

type GraphQLEndpoint = string;

`GetApolloClientCacheToken`

import {GetApolloClientCacheToken} from 'fusion-apollo-universal-client';

Optional - A function that returns an Apollo cache implementation.

type GetApolloClientCache = (ctx: Context) => ApolloCache

Default value

The default cache implementation uses InMemoryCache.

`ApolloClientCredentialsToken`

import {ApolloClientCredentialsToken} from 'fusion-apollo-universal-client';

Optional - A configuration value that provides the value of credentials value passed directly into the fetch implementation. The default value is same-origin.

type ApolloClientCredentials = 'omit' | 'include' | 'same-origin'

`GetApolloClientLinksToken`

import {GetApolloClientLinksToken} from 'fusion-apollo-universal-client';

Optional - A configuration value that provides a array of ApolloLinks. The default links are provided as an argument to the provided function.

type GetApolloClientLinks = (Array<ApolloLinkType>) => Array<ApolloLinkType>

`ApolloClientResolversToken`

import { ApolloClientResolversToken } from "fusion-apollo-universal-client";

Optional - Provides the resolvers for local state management.

`ApolloBodyParserConfigToken`

import { ApolloBodyParserConfigToken } from "fusion-apollo-universal-client";
// Example for increasing the json limit
app.register(ApolloBodyParserConfigToken, {
  jsonLimit: '5mb',
});

Optional - Provides body parser config to koa-bodyparser for apollo-server. See https://github.com/koajs/bodyparser

gql

import {gql} from 'fusion-plugin-apollo';

A macro for loading graphql queries and schemas. Takes a relative path string and returns the contents of the graphql schema/query as a string.

type gql = (path: string): DocumentNode

path: string - Relative path to the graphql schema/query file. NOTE: This must be a string literal, dynamic paths are not supported.

GraphQlSchemaToken is required whenever GraphQLEndpointToken is provided

Type of issue

Bug

Description

After upgrading to newest fusion-plugin-apollo the app throws an error regarding missing token.

Current behavior

Throws an error about missing GraphQlSchemaToken while GraphQLEndpointToken is provided.
Important note: I'm trying to connect to external graphql server.

Expected behavior

Shouldn't throw an error :)

Steps to reproduce

clone the repository: https://github.com/dontmakemethink/fusionreproduced

yarn create fusion-app my-fusion-app
follow the docs to add apollo to the project (https://fusionjs.com/api/fusion-apollo/)
use GraphQLEndpointToken
