But I am unable to download the physical file. Any help will be much appreciated. Django nginx webserver no accepts api post Cron Job. Keyboard doesn't disappear if you tap "Done" since the last Google Chrome update.
Hence, we need a way to paas actual file and not just file name. As fs can't handle that for us, so we use a npm module npm i streamifier --save. The above code won't work as there is one more dependency that we need to add in our app. We would need to install npm i express-fileupload --save and add the following statements in app. Compile and you should be good to go.

And if you are already doing it, chances are that you may have seen an error similar to - node DeprecationWarning: GridStore is deprecated, and will be removed in a future version. Please use GridFSBucket instead. The npm module crypto is used to encrypt the filenames on being stored and read from the database.
Once the storage engine using GridFS is initialized, you have to just call it using the multer middleware. It is then passed to the respective route executing the various file storage operations. We initialize a GridFS stream as seen in the code below. The stream is needed to read the files from the database and also to help render an image to a browser when needed.
Note: The name file is used as a parameter in upload. We can also upload multiple files at once. Instead of upload. Note: The number of files uploaded can be less than the defined number of files. Using the stream initialized we can fetch all the files in the particular database using gfs. Once the files are obtained we map it to an array and ship the response. It is super simple to query GridFS for a single file based on a specific attribute like filename. Using the GridFS stream, you can query the database through the function gfs.
This is a slightly trickier part since you have to not only fetch a file from the database but also to render it as an image on the respective browser.
