jopen 10年前

IO.js 是为 V8 引擎编写的基于事件 IO 的实现。io.js就是node.js的一个分支，或者说是替代技术。io.js是node.js是原班开发队伍由于不满官方运营商 Joyent 而另起炉灶fork出来的一个分支，它目前来看完全兼容 npm ，和node.js的语法。io.js在其官方主页 https://iojs.org 上显示1.0稳定版支持Linux、Win32、Win64和Mac平台。

io.js 1.5.0 发布，此版本值得关注的改进如下：

  • buffer: 新 Buffer#indexOf() 方法

  • fs: 在 'fs' 方法的  options 对象属性不再执行一个 hasOwnProperty() 检测

  • tls: 解决了 PayPal 报告的类似 TLS 的内存泄漏问题

  • npm: 升级 npm 到 2.7.0 版本

    • 145af65#4887 Replace calls to thenode-gyp script bundled with npm by passing the--node-gyp=/path/to/node-gyp option to npm. Swap in pangyp or a version of node-gyp modified to work better with io.js without having to touch npm's code!  (@ackalker)

    • 2f6a1df#1999 Only run stop and startscripts (plus their pre- and post- scripts) when there's no restart script defined. This makes it easier to support graceful restarts of services managed by npm.  (@watilde /@scien)

    • 448efd0#2853 Add support for --dev and--prod to npm ls, so that you can list only the trees of production or development dependencies, as desired. (@watilde)

    • a0a8777#7463 Split the list printed bynpm run-script into lifecycle scripts and scripts directly invoked via npm run-script. (@watilde)

    • a5edc17#6749 init-package-json@1.3.1: Support for passing scopes to npm init so packages are initialized as part of that scope / organization / team. (@watilde)

  • TC: Colin Ihrig (@cjihrig) resigned from the TC due to his desire to do more code and fewer meetings.
