Apollo Bridge Link
When you don't have GraphQL server (yet) and want to use GraphQL on the client.
Demo: working example with source code and server.
Article about how to use it with dataloaders and authentication.
Use your own resolvers to non-graphql endpoints (like REST API, querying
filesystem in electron app etc.).
Idea
GraphQL client side development is great experience. But more then often company
doesn't have GraphQL server (yet). Bridge allows you to resolve GraphQL queries
and mutations the way you want (facing REST API eg.)
Allows gradual implementing of GraphQL within your project and doesn't require
to change backend. Schema created along the way will be corner stone for full
adoption of GraphQL on the backend.
Implementation
We created this tool for us to deliver web and native app. We use Apollo tools
and therefore this is implemented as Apollo Link.
The basic implementation is simple: this link allows you to create link that
accepts your schema and your resolvers. You can even mock the schema on the
client.
Demo: working example with source code and server.
How to use
Install
npm install apollo-client@beta apollo-bridge-link apollo-cache-inmemory@beta
create Apollo client
import { ApolloClient } from 'apollo-client';
import { BridgeLink } from 'apollo-bridge-link';
import { InMemoryCache } from 'apollo-cache-inmemory';
import schema from './schema';
import resolvers from './resolvers';
const mock = true;
const context = {
graphQl: 'is cool',
};
const contextware = (ctx, operation) => ({ inContext: 'from contextware' });
export const client = new ApolloClient({
link: BridgeLink({ schema, resolvers, mock, context, contextware });
cache: new InMemoryCache({ addTypename: true }),
});
Then use your graphQl queries and mutation as you would be facing GraphQL
server.

Need help, want help?
I eat my dog (cat, actually) food - I use this for client's projects. I do not
have enough time to put all enhancements into this library, but I am catching
up.
If you are developer, please submit issue or PR.
If you are company and want to help with implementing GraphQL (server/web
app/react native apps) and need help, ask me. I'm passionate programmer (Node,
React, GraphQl, ... ) and usually working in a team with more skills like
ReactNative.
