React Training Overview
React is a popular, high-performance JavaScript library for building fast, composable user interfaces. GraphQL is a new and innovative way to query and mutate graphs of data according to the needs of the GraphQL consumer. Relay is a React/GraphQL framework which manages the querying and mutating of data for React components consuming GraphQL services.
Accelebrate’s Introduction to React/GraphQL/Relay training class teaches experienced JavaScript developers the skills they need to immediately implement React/GraphQL/Relay in their applications.
Location and Pricing
Accelebrate offers instructor-led enterprise training for groups of 3 or more online or at your site. Most Accelebrate classes can be flexibly scheduled for your group, including delivery in half-day segments across a week or set of weeks. To receive a customized proposal and price quote for private corporate training on-site or online, please contact us.
In addition, some courses are available as live, instructor-led training from one of our partners.
Objectives
- Understand what React, GraphQL and Relay are and what problems they solve
- Gain a deeper knowledge of ES2015, JSX and RelayQL
- Learn how to configure React and GraphQL for Relay
- Implement unit tests for React/GraphQL/Relay components
- Learn React/GraphQL/Relay best practices
Prerequisites
All attendees must be experienced JavaScript developers with a fairly advanced understanding of JavaScript, including prototypes and functions as first class citizens. If your group doesn’t yet have this experience, we could readily add one or two days to the beginning of your course to appropriately prepare them.
