This project is mostly an integration piece for existing code samples from Multer’s storage engine documentation with s3fs as the substitution piece for file system. Existing solutions I found required buffering the multipart uploads into the actual filesystem which is difficult to scale.
Installation
npm install –save multer-s3
Usage
The optional cacheControl option sets the Cache-Control HTTP header that will be sent if you’re serving the files directly from S3. You can pass either a string or a function that returns a string.
Setting Custom Content-Type
The optional contentType option can be used to set Content/mime type of the file. By default the content type is set to application/octet-stream. If you want multer-s3 to automatically find the content-type of the file, use the multerS3.AUTO_CONTENT_TYPE constant. Here is an example that will detect the content type of the file being uploaded.
