The Future of Programming in Node.js

Isaac Schlueter :

There’s been a lot of debates, theories, and requests about Node’s core API patterns on this list lately. I’d like to clarify the actual plans of the project on these points.

Callbacks will remain the de facto way to implement asynchrony. Generators and Promises are interesting and will remain a userland option.

Streams are more consistent, faster, and 100% backwards compatible as of 0.10. The “compatibility mode” aka “old mode” is folded into the API more cleanly. You can pause() a flowing stream, and then start calling read() again safely. We’ll keep exposing streams from core APIs, and advocating extending the stream base classes in userland programs.

Domains will be refactored to support more generic continuation-tracking systems, to enable alternative error-handling mechanisms in userland. Eventually the Domain module will be a thing that could be done in userland, but it will continue to be bundled with the Node binary.

There will be no changes to the module system. None. It’s finished. It’s been finished for over a year. Any proposed changes must come with a clear reproducible bug that cannot be worked around or addressed with documentation.

TypeScript and CoffeeScript will not be added to core. However, as the module system will remain locked, anything that works today will keep working.

A stable C API shim will be added such that binary addons can be code-stable (and perhaps, binary-stable) across stable branches of Node for the most common use-cases. Note that the V8 API changed significantly in 0.12, so basically every binary addon is broken today. Also, it’s very difficult to bind to the appropriate openssl/zlib/c-ares/etc. We’re addressing that.

As new language features are added to V8, they’ll make their way into Node. We have no plans to “auto-enable” any specific flags. Sniff for what you need, and throw with a helpful error message if it’s not available.

The VM module is being refactored to bring the features of the "contextify" module into core, so that contexts work like everyone expects that they should. Multi-context support is being added to the VM module API as well.

Synchronous child process execution is being added, at long last.

v0.12 is nearing feature completion. Once we get there, we’ll be trying to get everyone to use it. After v0.12, there will probably not be any API changes before v1.0. Between v0.12 and v1.0, we’ll be focusing on performance, bug fixing, and stability.

We are done making breaking changes at the Node.js layer. If your program runs today, we’re doing everything we can to make sure that it will run next year, albeit faster and more reliably.

This is not a democracy. However, there’s plenty of room for everyone’s opinion. If you want to make exciting dramatic breaking changes to node-core, and you can’t find satisfaction by writing userland npm modules, then please fork joyent/node, give it a new name and logo, and go as completely crazy as you want.

OSS FTW.
