Software-update: Node.js 10.0.0

Node.js logo (75 pix) Node.js is open source en platformonafhankelijk, en is gericht op het ontwikkelen van server-sidewebapplicaties. Die applicaties worden geschreven in JavaScript en uitgevoerd binnen de Node.js runtime op de server. Het biedt een event-gedreven omgeving aan waarbij non-blocking i/o een belangrijk uitgangspunt is geweest. Voor meer informatie verwijzen we naar deze pagina. Het ontwikkelteam heeft versie 10.0 vrijgegeven, met kort daarop een kleine update. De belangrijkste verbeteringen die hierin zijn aangebracht, zijn hieronder voor je op een rijtje gezet:

Node v10.0.0 (Current)

Node.js 10.0.0 is the seventh major Node.js release since the launch of the Node.js Foundation. In October of 2018, it will become the next Active Long Term Support branch.

Partially in celebration of the N-API native addon API graduating from experimental status, this Node.js release also comes with a coordinated experimental release of Node-ChakraCore that has full support for N-API and advances the Time-Travel innovation with easier getting started using a VSCode extension.

Feature Highlights for the Node-ChakraCore release include:

  • Full support for N-API
  • Easy getting started with Time-Travel Debugging via a new Visual Studio Code Extension
  • TTD support for generators and async functions
  • Support for Inspector protocol
  • Increased stability and other assorted improvements
