MongoDB configuration

We are going to launch MongoDB in a Docker container. While being inside a Docker container, MongoDB will be exposed on a specific url that has following schema: mongodb://mongo_db_user:mongo_db_pswd@mongo:27017/mongo_db_name. As we can see, in order to connect to MongoDB from our code we will need to know mongo_db_user, mongo_db_pswd and mongo_db_name. This information will be set in .env file to avoid having our credentials inside the code. It is also convenient for the cases if some information would change, we will need to set new values only inside .env file and won’t directly touch the code so no need to rebuild whole program.

type EnvVariables struct {
DebugMode bool
MongoDBName string
MongoDBURL string

db/ folder structure

As you might have noticed, I have created a separate folder (package) for crawlers in the previous article so I want to keep all logic separately, divided, let’s say, to microservices. I am going to do the same with accessing, writing and reading information to/from a database.
