GraphQL app in Node.js, Apollo server with TypeScript and graphql-request

A simple GraphQL api server using Apollo. In this project, we will define simple CRUD operations on a mongo DB database with mongoose.

Project structure

The project is a decoupled structure of microservices using RabitMQ. The project is setup in a module structure where every Module has it's own GraphQL schema, queries, resolvers, types, dat. This makes it easy to seperate logic. Inside app/index.ts we read all Schema.graphql and Resolvers.ts from all modules. In this case, app/Person is a module of it's own.

Creating a new module

• Create a new folder inside app folder
• Add Schema.graphql which will hold the module graphQL schema
• Add Resolvers.ts which will have all your queries and mutation resolvers
• You can add optional files like types.d.ts for all your module typescript definitions and Database connection files or controllers.

Setup

• Setup RabitMQ locally or use an online version
• Clone the repo
• Run yarn or npm install to install project dependencies
• The app will be served on a GraphQL server using Apollo, the library generates a “frontend” which looks like so:
