What’s the correct way to handle errors with streams? I already know there’s an ‘error’ event you can listen on, but I want to know some more details about arbitrarily complicated situations. For starters, what do you do when you want to do a simple pipe chain: input.pipe(transformA).pipe(transformB).pipe(transformC)… And how do you properly create one … Read more
I’m hacking on a Node program that uses smtp-protocol to capture SMTP emails and act on the mail data. The library provides the mail data as a stream, and I don’t know how to get that into a string. I’m currently writing it to stdout with stream.pipe(process.stdout, { end: false }), but as I said, … Read more
I understand that a stream is a representation of a sequence of bytes. Each stream provides means for reading and writing bytes to its given backing store. But what is the point of the stream? Why isn’t the backing store itself what we interact with? For whatever reason this concept just isn’t clicking for me. … Read more

Well, this one seems quite simple, and it is. All you have to do to download a file to your server is: file_put_contents(“Tmpfile.zip”, file_get_contents(“http://someurl/file.zip”)); Only there is one problem. What if you have a large file, like 100mb. Then, you will run out of memory, and not be able to download the file. What I … Read more
I was surprised to find today that I couldn’t track down any simple way to write the contents of an InputStream to an OutputStream in Java. Obviously, the byte buffer code isn’t difficult to write, but I suspect I’m just missing something which would make my life easier (and the code clearer). So, given an … Read more
