This is the sample project that belongs to the React & Apollo Tutorial on How to GraphQL.

git clone https://github.com/howtographql/react-apollo/

Go to the server folder, install dependencies and start the server.

cd react-apollo/server
yarn install
yarn dev

Note: If you want to interact with the GraphQL API of the server inside a GraphQL Playground, you can navigate to http://localhost:4000.

Now that the server is running, you can start the React app as well. The commands need to be run in a new terminal tab/window inside the root directory react-apollo (because the current tab is blocked by the process running the server):

yarn install
yarn start

You can now open your browser and use the app on http://localhost:3000.
