Broccoli Caching Writer

[![Build status][appveyor-badge]][appveyor-badge-url]

Drop-in-replacement for
broccoli-plugin adding a thin
caching layer based on the computed hash of the input directory trees. If any
file in an input node has changed, the build method will be called,
otherwise (if input is the same) the results of the last build call will be
used instead.

Example

``js
var Plugin = require('broccoli-caching-writer');

MyPlugin.prototype = Object.create(Plugin.prototype);
MyPlugin.prototype.constructor = MyPlugin;
function MyPlugin(inputNodes, options) {
options = options || {};
// options.inputFiles === array of globs, to consider for the cache key
Plugin.call(this, inputNodes, {
annotation: options.annotation
});
}

MyPlugin.prototype.build = function() {
// cache has been busted
// do anything, for example:
// 1. read from this.inputPaths
// 2. do something based on the result
// 3. and then, write to this.outputPath
};
`

Documentation

$3

Call this base class constructor from your subclass constructor.

* inputNodes: An array of input nodes.

* options:

* name, annotation, persistentOutput: Same as
broccoli-plugin;
see there.

* cacheInclude (default: []): An array of regular expressions that files and directories in an input node must pass (match at least one pattern) in order to be included in the cache hash for rebuilds. In other words, a whitelist of patterns that identify which files and/or directories can trigger a rebuild.

* cacheExclude (default: []): An array of regular expressions that files and directories in an input node cannot pass in order to be included in the cache hash for rebuilds. In other words, a blacklist of patterns that identify which files and/or directories will never trigger a rebuild.

Note, in the case when a file or directory matches both an include and exlude pattern, the exclude pattern wins
