This node.js project is a small demo of how to implement many of the functional requirements present in everyday APIs we use.

It covers the following API Styles:

• REST: see rest folder.
• GraphQL: see graphql folder.
• gRPC: see grpc folder.

It has been developed using:

• express as the main app server.
• apollo-server-express, as an express middleware.
• mongoose, to model and access MongoDB objects.
• nodemon, to simplify the development process.
• @grpc/grpc-js, a pure JavaScript gRPC client.
• cors, an Express middleware to add CORS support to a web service.
• got, an HTTP client for node.js, used for WebHooks.

To install the dependencies, run npm install.

Then configure your MongoDB in nodemon.json.

To run the project, exec npm start.

Finally, to turn to grpc client on, exec npm run grpcc.

Also note, the GraphQL service has the graphiql web interface enabled for your convenience. It's available in /graphql.
