GraphQL Server Example with express-graphql

This example shows how to implement a GraphQL server with TypeScript with the following stack:

• Express GraphQL: Express middleware for GraphQL HTTP servers
• GraphQL Nexus: GraphQL schema definition and resolver implementation
• Prisma Client: Databases access (ORM)
• Prisma Migrate: Database migrations
• SQLite: Local, file-based SQL database

Contents

• Getting Started
• Using the GraphQL API
• Evolving the app
• Switch to another database (e.g. PostgreSQL, MySQL, SQL Server)
• Next steps

Getting started

1. Download example and install dependencies

Download this example:

curl -LJO 'https://github.com/sinhaGuild/pg-nexus-ts-gql/archive/refs/heads/main.zip'

Install npm dependencies:

cd api
yarn install
yarn run dev

Alternative: Clone the entire repo

Clone this repository:

git clone git@github.com:sinhaGuild/pg-nexus-ts-gql.git --depth=1

Install npm dependencies:

cd api/
yarn install

2. Create and seed the database

Run the following command to create your SQLite database file. This also creates the User and Post tables that are defined in prisma/schema.prisma:

npx prisma migrate dev --name init

When npx prisma migrate dev is executed against a newly created database, seeding is also triggered. The seed file in prisma/seed.ts will be executed and your database will be populated with the sample data.

3. Start the GraphQL server

Launch your GraphQL server with this command:

yarn run dev

Navigate to http://localhost:4000 in your browser to explore the API of your GraphQL server in a GraphQL Playground.
