mgo

Package mgo

The mgo package provides a MongoDB client for Go applications.

Usage

Import the mgo package into your Go file:

import "github.com/thirathawat/mgo"

Configuration

The mgo package reads its configuration from environment variables. Here are the supported environment variables:

• ADDRS: A comma-separated list of host:port addresses for the MongoDB servers.
• NAME: The name of the MongoDB database.
• AUTH_SOURCE: The name of the MongoDB authentication database.
• USER: The name of the MongoDB user.
• PASSWORD: The password for the MongoDB user.

You can use the readConfig function to read the configuration from the environment. It returns a config struct that holds the configuration values.

Creating a MongoDB Client

To create a new MongoDB client and establish a connection, use the New function:

db, cleanup, err := mgo.New()
if err != nil {
    // handle error
}
defer cleanup()

The New function returns a mongo.Database object that represents the MongoDB database. It also returns a cleanup function that should be deferred to close the connection when you're done with the database.

Database Operations

Once you have a mongo.Database object, you can perform various operations on the database, such as inserting, updating, and querying documents. Refer to the MongoDB Go Driver documentation for more information on working with the MongoDB database.

Example

Here's an example of how to use the mgo package:

package main

import (
    "github.com/tirathawat/mgo"
)

func main() {
    db, cleanup, err := mgo.New()
    if err != nil {
        // handle error
    }
    defer cleanup()

    // Perform database operations...
}

Conclusion

The mgo package provides a convenient way to connect to a MongoDB database and perform database operations in your Go applications. It simplifies the process of configuring the client and establishing a connection, allowing you to focus on building your application's functionality.
