This a backend Express app that demonstrates how to:

• Create and deploy a POST endpoint that creates a resource and responds created object
• Create and deploy a GET endpoint that returns an array of objects
• Create and deploy a GET endpoint that returns a single matching object based on the id in the path and req.params.id
• Create and deploy a PUT/PATCH endpoint that updates a resource with the matching id and responds the updated object
• Create and deploy a DELETE endpoint that deletes a resource with the matching id and responds the deleted object
• Add JSON deserialization middleware and use the body in a route
• Use params to simplify the extraction of “id” from a router
• Utilize Router to implement a horizontally scalable Express App architecture
• Use the pg library with $1, $2, $3 syntax to sanitize our SQL queries to prevent SQL injection.
• Use pg to make queries against a Postgres DB
• Connect to a Postgres DB using the pg node module

This app uses:

• Nodejs
• Express
• PostgreSQL
