Directory Cache

A directory cache, built on top of DirectoryWatcher. The cache reads all the files in a directory and caches their content. When files are changed, added, deleted etc the cache will update and fire an event using the good old EventEmitter API.

Install

    npm install directory-cache

Example

var DirectoryCache = require('directory-cache');

var cache = DirectoryCache.create({
    directory: '/path/to/the/moon'
}/*, optionally supply a callback to automatically call .init */);

cache.on('add', function(files) {
    var content = cache.getFileContent(files[0]);
    // do something with content
});

cache.on('change', function(files) {
    // etc...
});

cache.on('delete', function(files) {
    // etc..
});

cache.on('error', function(err) {
    // waaaaaaaaah!
})

cache.init(function(err) {
    if (err) 
        return console.log('ahhhhhhhhhhhh!', err);

    var content = cache.getFileContent('moo.txt'); // returns the content of /path/to/the/moon/moo.txt

    var files = cache.getFiles(); // returns all the files in /path/to/the/moon

});

using filters

// regular expression retains only json files

var DirectoryCache = require('directory-cache');

var cache = DirectoryCache.create({
    directory: '/path/to/the/moon',
    filter: /.*json/
});

// function filter that retains only json files

var cache2 = DirectoryCache.create({
    directory: '/path/to/the/moon',
    filter: function(file) { return file.slice(-5).toLowerCase() === '.json' }
});
