TypeScript GraphQL Code Generator – Generate GraphQL Types with Apollo Codegen Tutorial. The author of “The Design of Everyday Things” has a philosophy for what he believes constitutes good design.

Don Norman, the author of “The Design of Everyday Things” has a philosophy for what he believes constitutes good design. Don says that good design is primarily discoverability and feedback.
For example, when you encounter something new (like, a new codebase), how quickly can you discover what you can do (discoverability)? And then after you’ve taken some action, how immediately do you get to know if what you did was correct (feedback)?
Typed languages like TypeScript give us compile-time types, and types act as an excellent form of feedback. They let us know if what we’re attempting to do is going to work — and they let us know immediately.
For developers building client-side GraphQL applications using Apollo Client and React, compiling it with TypeScript is a good idea. But without compile-time types on our GraphQL operations, we have to wait until we execute our queries and mutations to tell if we’re doing something wrong.
In this post, you’ll learn how to use Apollo’s GraphQL codegen to generate TypeScript types for GraphQL operations in your Apollo Client project.
The Apollo CLI (which lives on GitHub at apollographql/apollo-tooling) contains a collection of helpful utilities to assist us with maintaining GraphQL applications in production.
One of the tools from the CLI is the GraphQL codegen feature. It lets us:
And that’s exactly what we’ll do. Let’s get started.
Learn TypeScript | TypeScript Crash Course | TypeScript Tutorial for Beginners: My goal with this courses is just give your the fundamentals of the language, show you what TypeScript is and how to use it. We as developers don't have time neither can we afford to spend too much time on any tehcnology.
