This repository showcases an API gateway implementation using Node.js with SQLite as the database, Express as the web application framework, and Apollo Server as the GraphQL server. It serves as a centralized entry point for various microservices, offering a unified API for clients.
- GraphQL API powered by Apollo Server
- SQLite database for storing books and stories
- REST endpoints for querying and manipulating books and stories
- Integration with gRPC client for remote services (books and stories)
- Cross-Origin Resource Sharing (CORS) support
- Request body parsing using body-parser
Clone the repository:
git clone https://github.com/Melek-E/api-gateway.git
cd api-gatewayInstall the dependencies:
npm installStart the server:
npm startThe API gateway will be accessible at http://localhost:3000.
The API gateway provides the following endpoints:
- GET /books: Retrieve all books.
- GET /books/:id: Retrieve a specific book by ID.
- POST /book: Create a new book.
- GET /stories: Retrieve all stories.
- GET /stories/:id: Retrieve a specific story by ID.
- POST /story: Create a new story.
The GraphQL API is available at http://localhost:3000/graphql and can be accessed using tools like GraphQL Playground or Postman.
The API gateway's configuration can be adjusted by modifying the following files:
- book.proto: Protocol Buffers file defining the gRPC service and message definitions for books.
- story.proto: Protocol Buffers file defining the gRPC service and message definitions for stories.
- resolvers.js: Houses the resolver functions for GraphQL queries and mutations.
- schema.js: Defines the GraphQL schema using the GraphQL Schema Definition Language (SDL).
