Open API (Swagger)

When running the project locally, visit http://localhost:3000/swagger to access the Swagger UI.

Using MongoDB locally with Docker

Download the latest MongoDB image.

docker pull mongo:latest

Run the container in detached mode, or in the background. Map the container ports with host ports so that the database can be accessed from a local host-level application. The port used is from the MongoDB documentation.

docker run -d -p 27017:27017 mongo

List docker containers to see if the mongo container is running.

docker container ls

Using Redis locally with Docker

Run the container in detached mode, or in the background. Map the container ports with host ports so that redis can be accessed from a local host-level application.

docker run -d -p 6379:6379 redis

List docker containers to see if the redis container is running.

docker container ls

Using redis-cli to test Redis

Start redis-cli using the following command.

npm run rediscli

The rediscli script is configured to use the default host and port 127.0.0.1:6379 of a local machine in package.json.

We can query redis to see if one of our project's cache keys exist. We can use exists categories or exists posts. A response of (integer) 1 means the keys exist. To view the data stored for a cache key, use get categories or get posts.
