By "oldie" function, do you mean functions that expect node-style callbacks? e.g. function myCallback (err, result) {...}

- styfle 9y agoCorrect. Most node core APIs are written this way and now core ships an utility function[0] to wrap those functions in a promise. [0]: https://medium.com/@styfle/promises-in-node-js-8-x-core-d6a8a93e85a2 https://medium.com/@styfle/promises-in-node-js-8-x-core-d6a8...
- mastax 9y agoIt seems to me that Node should ship promisify-ed versions of all these functions (e.g. fs.readFileAsync). Over time they could replace the implementation with ones that use the OS Async APIs, though perhaps this step is unnecessary if you're already using an event loop underneath.
- lhnz 9y agoUntil then you can use `mz` for a modernised API[0]. [0] https://github.com/normalize/mz https://github.com/normalize/mz
- NoInkling 9y agoI mean, they've been debating about how to add a promisified API for years (see for example https://github.com/nodejs/node/pull/5020 https://github.com/nodejs/node/pull/5020) but nothing has come of it. util.promisify is a welcome addition, but very late for a first step.
