Function: uploadMedia()
> uploadMedia(bucketName, buffer, originalname, contentType): Promise<InterfaceUploadResult>
Uploads a media file to a specified S3 bucket, calculating its hash for naming and uniqueness.
The uploadMedia function calculates the SHA-256 hash of the provided buffer to generate a unique object key.
It first checks if a file with the same hash already exists in the bucket using the HeadObjectCommand.
If the file does not exist, it uploads the file using the PutObjectCommand. It supports both image and video uploads
by assigning appropriate prefixes to the object key.
Parameters
bucketName
string
The name of the S3 bucket where the file will be uploaded.
buffer
Buffer
The file content as a buffer.
originalname
string
The original file name, used to determine the file extension.
contentType
An object specifying the content type of the file.
ContentType
string
Returns
Promise<InterfaceUploadResult>
A promise that resolves to an object containing the file's existence status, object key, hash, and hash algorithm.
Example
const result = await uploadMedia("my-bucket", fileBuffer, "image.png", \{ ContentType: "image/png" \});
console.log(result);
