schema

Connecting to MongoDB

An example of how you would connect to MongoDB and perform basic CRUD operations. In this example, we use a pre-defined schema that facilitates the mapping of MongoDB documents to Go data structures

There's another example that performs the same operation but without using a pre-defined schema.

Setup

Here's a sequence of steps to run this project.

1. Launch a shell session and start MongoDB (server) via Docker:

   $ docker-compose up

2. You can connect to Mongo via docker interactive tty interface.

   $ docker exec -it mongo mongo -u nobody -p secrets go-recipes

3. Run Go program.

   $ go run ./main.go

4. When you are done, just shut mongo down.

   $ docker-compose down

5. Alternatively, you can run everything with just 2 commands.

   $ make
   $ make teardown    # Run this to remove the container
