React, Relay, and GraphQL Training Course
In the years following 2010, the shift from native web platforms to mobile applications necessitated a more efficient data request system. At that time, companies often relied on RESTful services, which were found to be inadequate for handling complex requests in React applications, leading to slow response times. To address this issue, Facebook engineers developed GraphQL and Relay. GraphQL streamlines the relationship between client and API by automating requests, while the JavaScript framework, Relay, efficiently manages data within React applications. Both GraphQL and Relay are utilized to enhance a React application's user interface.
This instructor-led, live training (online or onsite) is designed for developers who want to use GraphQL and Relay to manage data in their React applications.
By the end of this training, participants will be able to:
- Set up the necessary development environment to start managing data for React applications.
- Create responsive UI interactions that provide instant feedback.
- Consolidate data from multiple sources into a single, convenient API.
- Pre-fetch data using GraphQL and Relay.
Format of the Course
- Interactive lecture and discussion sessions.
- Plenty of exercises and practical activities.
- Hands-on implementation in a live-lab environment.
