inmemfilecache

A very simple in memory file cache for node.js. It's a drop in replacement for fs.readFile and fs.readSyncFile

Files are cached LRU style in memory. By default inmemfilecache monitors the folders of files in the cache. If a file changes it's removed from the cache. This means you can use it in dev environments and not have to disable it while your server is running.

Usage

var Cache = require('inmemfilecache');
var cache = new Cache();

cache.readFile('/path/to/file', callback);

API

• Cache(options)

  options are optional

  • cacheSizeLimit

    the number of bytes the cache can hold. Defaults to 64 meg.

  • checkForFileChanges

    removes files from cache if the file changes. Default = true

• Cache.readFile

  See fs.readFile

• Cache.readFileSync

  See fs.readFileSync

• Cache.setCacheLimit

  Changes the cache's size limit. If it's over this limit things will be removed from the cache until it's under the limit.

Notes:

Your app will not exit as along as folders are being tracked. Call cache.clear to clear all folder trackers.
