Examples

On the GitHub repository there are a few simple examples of how to use different TypeGraphQL features and how well they integrate with 3rd party libraries.

To run an example, simply go to the subdirectory (e.g. cd ./simple-usage), and then start the server (npx ts-node ./index.ts).

Each subdirectory contains a examples.graphql file with predefined GraphQL queries/mutations/subscriptions that you can use in Apollo Studio (http://localhost:4000) and play with them by modifying their shape and data.

Basics

• Simple usage of fields, basic types and resolvers

Advanced

• Enums and unions
• Subscriptions (simple)
• Subscriptions (using Redis) **
• Interfaces
• Extensions (metadata)

Features usage

• Dependency injection (IoC container)
  • Scoped containers
• Authorization
• Validation
  • Custom validation
• Types inheritance
• Resolvers inheritance
• Generic types
• Mixin classes
• Middlewares and Custom Decorators
• Query complexity

3rd party libs integration

• TypeORM (manual, synchronous) *
• TypeORM (automatic, lazy relations) *
• MikroORM *
• Typegoose *
• Apollo Federation
• Apollo Federation 2
• Apollo Cache Control
• GraphQL Scalars
• TSyringe

* Note that we need to provide the environment variable DATABASE_URL with connection parameters to your local database
** Note that we need to provide the environment variable REDIS_URL with connection parameters to your local Redis instance
