In memory server

[masterit-technologies]

Hi everyone, Is it possible to use ftp-srv just for stream redirecting?

I need to catch event STOR and save data into my database, not write on hdd.

Maybe it is stupide question but I dont have any experiences with it.

If its possible can you provide me some short example how to do that?
Thanks.

To handle file system operations differently, you'd have to implement a custom file system.
By using the example code as a starting point, you'd have to implement a custom write function that handles your specific logic.

Hi, thanks for the reply, I solved it as you say. I overwrite the write function and used a memory-stream package, then I was able to use the data in memory for my own specific logic.

Something like that.

write(fileName, { append, start }) {
        const { fsPath, clientPath } = this._resolvePath(fileName);
        let stream = new MemoryStream(); //memory-stream npm package
        stream.on('finish', function () {
              let data = Buffer.concat(this.buffer).toString('base64'); // data in base64
             //do your work here
        });
        return {
            stream: stream,
            clientPath: clientPath
        };
}
