MongoDB CRUD the MVC way with Passport Authentication 49
Let’s query the MongoDB via terminal
batman
MongoDB shell (mongo.exe on Windows machine, mongo binary on Linux) will automatically
connect to the default test database if you run it without any parameters. In order to switch to
another database (in this example called todos) execute the following command:
1 use todos
Databases and collections are lazily created when you insert your first document, which means that
if you use the use todos command from above, but you don’t insert any documents, the database
will not be created.
In order to show all the available databases execute the following command:
1 show dbs
A MongoDB collection is a list of MongoDB documents and is the equivalent of a
relational database table. Unlike a table, a collection doesn’t enforce any type of schema. To show
all available collections in the database execute:
1 show collections
