MongoDB Example

Github StackBlitz

This project demonstrates how to connect to a MongoDB database in a Go application using the Fiber framework.

Prerequisites​

Ensure you have the following installed:

Setup​

  1. Clone the repository:

    git clone https://github.com/gofiber/recipes.git
    cd recipes/mongodb

  2. Install dependencies:

    go get

  3. Start MongoDB using Docker:

    docker-compose up -d

  4. (Optional) Set the MONGO_URI environment variable. Defaults to mongodb://localhost:27017/fiber_test:

    export MONGO_URI="mongodb://localhost:27017/fiber_test"

Running the Application​

  1. Start the application: 
    go run main.go

Example​

Here is an example of how to connect to a MongoDB database in a Fiber application:

package main

import (
    "context"
    "log"
    "time"

    "github.com/gofiber/fiber/v3"
    "go.mongodb.org/mongo-driver/mongo"
    "go.mongodb.org/mongo-driver/mongo/options"
)

func main() {
    // MongoDB connection
    ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
    defer cancel()
    client, err := mongo.Connect(ctx, options.Client().ApplyURI("mongodb://localhost:27017"))
    if err != nil {
        log.Fatal(err)
    }
    defer client.Disconnect(context.Background())

    // Fiber instance
    app := fiber.New()

    // Routes
    app.Get("/", func(c fiber.Ctx) error {
        return c.SendString("Hello, MongoDB!")
    })

    // Start server
    log.Fatal(app.Listen(":3000"))
}
