+# flat-cache
+> A stupidly simple key/value storage using files to persist the data
+
+[![NPM Version](http://img.shields.io/npm/v/flat-cache.svg?style=flat)](https://npmjs.org/package/flat-cache)
+[![Build Status](http://img.shields.io/travis/royriojas/flat-cache.svg?style=flat)](https://travis-ci.org/royriojas/flat-cache)
+
+## install
+
+```bash
+npm i --save flat-cache
+```
+
+## Usage
+
+```js
+var flatCache = require('flat-cache')
+// loads the cache, if one does not exists for the given
+// Id a new one will be prepared to be created
+var cache = flatCache.load('cacheId');
+
+// sets a key on the cache
+cache.setKey('key', { foo: 'var' });
+
+// get a key from the cache
+cache.getKey('key') // { foo: 'var' }
+
+// fetch the entire persisted object
+cache.all() // { 'key': { foo: 'var' } }
+
+// remove a key
+cache.removeKey('key'); // removes a key from the cache
+
+// save it to disk
+cache.save(); // very important, if you don't save no changes will be persisted.
+// cache.save( true /* noPrune */) // can be used to prevent the removal of non visited keys
+
+// loads the cache from a given directory, if one does
+// not exists for the given Id a new one will be prepared to be created
+var cache = flatCache.load('cacheId', path.resolve('./path/to/folder'));
+
+// The following methods are useful to clear the cache
+// delete a given cache
+flatCache.clearCacheById('cacheId') // removes the cacheId document if one exists.
+
+// delete all cache
+flatCache.clearAll(); // remove the cache directory
+```
+
+## Motivation for this module
+
+I needed a super simple and dumb **in-memory cache** with optional disk persistance in order to make
+a script that will beutify files with `esformatter` only execute on the files that were changed since the last run.
+To make that possible we need to store the `fileSize` and `modificationTime` of the files. So a simple `key/value`
+storage was needed and Bam! this module was born.
+
+## Important notes
+- If no directory is especified when the `load` method is called, a folder named `.cache` will be created
+  inside the module directory when `cache.save` is called. If you're committing your `node_modules` to any vcs, you
+  might want to ignore the default `.cache` folder, or specify a custom directory.
+- The values set on the keys of the cache should be `stringify-able` ones, meaning no circular references
+- All the changes to the cache state are done to memory
+- I could have used a timer or `Object.observe` to deliver the changes to disk, but I wanted to keep this module
+  intentionally dumb and simple
+- Non visited keys are removed when `cache.save()` is called. If this is not desired, you can pass `true` to the save call
+  like: `cache.save( true /* noPrune */ )`.

+    * Beautified file
+    
+  - fix changelog title style ([#14](https://github.com/royriojas/flat-cache/issues/14)) - [af8338a]( https://github.com/royriojas/flat-cache/commit/af8338a ), [前端小武](https://github.com/前端小武), 19/12/2016 23:34:48
+
+    
+## v1.2.2
+- **Bug Fixes**
+  - Do not crash if cache file is invalid JSON. ([#13](https://github.com/royriojas/flat-cache/issues/13)) - [87beaa6]( https://github.com/royriojas/flat-cache/commit/87beaa6 ), [Roy Riojas](https://github.com/Roy Riojas), 19/12/2016 21:03:35
+
+    Fixes <a target="_blank" class="info-link" href="https://github.com/royriojas/flat-cache/issues/12"><span>#12</span></a>
+    
+    Not sure under which situations a cache file might exist that does
+    not contain a valid JSON structure, but just in case to cover
+    the possibility of this happening a try catch block has been added
+    
+    If the cache is somehow not valid the cache will be discarded an a
+    a new cache will be stored instead
+- **Other changes**
+  - Added travis ci support for modern node versions ([#11](https://github.com/royriojas/flat-cache/issues/11)) - [1c2b1f7]( https://github.com/royriojas/flat-cache/commit/1c2b1f7 ), [Amila Welihinda](https://github.com/Amila Welihinda), 11/11/2016 02:47:52
+
+    
+  - Bumping `circular-son` version ([#10](https://github.com/royriojas/flat-cache/issues/10)) - [4d5e861]( https://github.com/royriojas/flat-cache/commit/4d5e861 ), [Andrea Giammarchi](https://github.com/Andrea Giammarchi), 02/08/2016 09:13:52
+
+    As mentioned in https://github.com/WebReflection/circular-json/issues/25 `circular-json` wan't rightly implementing the license field.
+    
+    Latest version bump changed only that bit so that ESLint should now be happy.
+## v1.2.1
+- **Bug Fixes**
+  - Add missing utils.js file to the package. closes [#8](https://github.com/royriojas/flat-cache/issues/8) - [ec10cf2]( https://github.com/royriojas/flat-cache/commit/ec10cf2 ), [Roy Riojas](https://github.com/Roy Riojas), 01/08/2016 04:18:57
+
+

+
+    
+## v1.0.11
+- **Features**
+  - Add noPrune option to cache.save() method. closes [#7](https://github.com/royriojas/flat-cache/issues/7) - [2c8016a]( https://github.com/royriojas/flat-cache/commit/2c8016a ), [Roy Riojas](https://github.com/Roy Riojas), 01/08/2016 04:00:29

+
+    
+- **Bug Fixes**
+  - Remove UTF16 BOM stripping - [4a41e22]( https://github.com/royriojas/flat-cache/commit/4a41e22 ), [Jean Ponchon](https://github.com/Jean Ponchon), 29/07/2016 04:18:06
+
+    Since we control both writing and reading of JSON stream, there no needs 
+    to handle unicode BOM.
+  - Use circular-json to handle circular references (fix [#5](https://github.com/royriojas/flat-cache/issues/5)) - [cd7aeed]( https://github.com/royriojas/flat-cache/commit/cd7aeed ), [Jean Ponchon](https://github.com/Jean Ponchon), 25/07/2016 13:11:59
