Node.js 8: The First Week
This week, we got the release of Node.js 8 – an entirely new version of Node.js, heading toward becoming an LTS release line in October. The release of Node.js 8 came with quite a few hefty new features, many small improvements, and tons of new opportunities for developers.
Because of just how massive Node.js 8 was – both the release itself and the community’s overwhelmingly positive response – I wanted to share some of the highlights from the first week of Node.js 8.
Some of the Most Exciting Features of Node.js 8
Key new features to keep an eye on with the release of Node.js 8 – which was one of, if not the, biggest semver major releases since the initial release of Node.js 4.0.0.
- Async Hooks, a diagnostics tool that’s been in development for quite some time, has finally landed!
- Node.js 8 now ships with V8 5.8, which includes TurboFan and Ignition. One key thing to note is that these are not enabled by default.
- The
util.promisify()feature allows Node.js callback-style APIs to be wrapped in a Promise. - With the release of Node.js 8 has come the parallel release of npm@5, with a ton of improvements and new features.
- A new *experimental *JavaScript Inspector API has shipped
