Readable-stream

Streaming Consistency

Since Node's streaming Api is still changing and is in 'unstable' category, writing a npm module using streams may cause some unexpected behaviors on older versions of Node. To ensure that streams are compatible with older versions of Node, a drop-in replacement for stream is available called 'readable-stream'.

Streaming Lines

Line by Line

There are many streaming modules on npm to read lines from text files, but many are inaccurate and slow. Inaccurate means that there is a failure to read many lines and slow means that files with a lot of text per line will cause the modules to crawl.

Removing Stylesheet Rules

Off with the Rule

Most of the time, css rules are overridden to get a different style, but some rules need to be outright removed. For example, if a hover effect is in place when javascript is disabled, but the rule might interfere with the javascript code when javascript is enabled. This might happen when using a jQuery plugin for menu creation or text effect.

jQuery Event Handler Adapter

Bridging the Gap

Older versions of jQuery are still being used (<= 1.6), and those versions do not support the new "on" method of attaching event handlers to elements. If you were authoring jQuery plugins and want to ensure compatibility when working with events, then you would want to write an adapter inside your plugin.
