What are the best practices for integrating Cloudinary with Go Fiber for large file uploads

1. Use the `upload_large` Method:
- Cloudinary's `upload_large` method allows you to upload large files in chunks, which is more efficient and scalable for handling large files.

2. Stream the File:
- Stream the file directly from the client to Cloudinary, bypassing your server. This approach reduces server load and improves performance.

3. Use the `upload_widget`:
- Cloudinary's `upload_widget` is an interactive, feature-rich method for uploading files directly to Cloudinary. It includes a complete graphical interface and supports various file sources.

4. Configure the `BodyLimit`:
- Set the `BodyLimit` in your Fiber application to handle larger files. The default limit is 4MB, which can be increased as needed.

5. Use the `StreamRequestBody`:
- Enable `StreamRequestBody` to handle large files by streaming the request body directly to Cloudinary.

6. Handle Errors:
- Implement error handling to ensure that your application can handle any errors that may occur during the upload process.

7. Monitor Upload Progress:
- Monitor the upload progress to provide a better user experience and handle any errors that may occur during the upload process.

8. Use a Cloudinary SDK:
- Use a Cloudinary SDK for Go to simplify the integration and handle various upload scenarios efficiently.

Here is an example of how to use the `upload_large` method in Go Fiber:

go
package main

import (
    "context"
    "fmt"
    "io"
    "log"
    "net/http"

    "github.com/gofiber/fiber/v2"
    "github.com/cloudinary/cloudinary-go/v2"
    "github.com/cloudinary/cloudinary-go/v2/api/uploader"
)

func main() {
    app := fiber.New(fiber.Config{
        BodyLimit: 100 * 1024 * 1024, // 100MB
    })

    // Initialize Cloudinary
    cldnry, err := cloudinary.NewFromAPIKey("your_api_key", "your_api_secret", "your_cloud_name")
    if err != nil {
        log.Fatal(err)
    }

    // Define the upload preset
    preset := "your_upload_preset"

    // Define the upload method
    upload := func(ctx context.Context, file io.Reader, filename string) (string, error) {
        // Upload the file in chunks
        uploadParams := &uploader.UploadParams{
            PublicID:   filename,
            ResourceType: uploader.File,
            UseFilename: true,
            Preset:     preset,
        }
        uploadResp, err := cldnry.Upload.Upload(ctx, file, uploadParams)
        if err != nil {
            return "", err
        }
        return uploadResp.PublicID, nil
    }

    // Define the upload endpoint
    app.Post("/upload", func(c *fiber.Ctx) error {
        // Get the file from the request body
        file, err := c.FormFile("file")
        if err != nil {
            return c.Status(fiber.StatusBadRequest).JSON(fiber.Map{"error": err})
        }

        // Upload the file
        publicID, err := upload(c.Context(), file.File, file.Filename)
        if err != nil {
            return c.Status(fiber.StatusInternalServerError).JSON(fiber.Map{"error": err})
        }

        // Return the uploaded file's public ID
        return c.Status(fiber.StatusOK).JSON(fiber.Map{"public_id": publicID})
    })

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

This example demonstrates how to handle large file uploads using the `upload_large` method in Go Fiber.
