+# 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 */ )`.

+
+    * Removed the need for del
+    
+    Removed the need for del as newer versions have broken backwards
+    compatibility. del mainly uses rimraf for deleting folders
+    and files, replaceing it with rimraf only is a minimal change.
+

+## 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
+
+    
+## v1.2.0
+- **Documentation**
+  - Add documentation about noPrune option - [23e11f9]( https://github.com/royriojas/flat-cache/commit/23e11f9 ), [Roy Riojas](https://github.com/Roy Riojas), 01/08/2016 04:06:49
+
+    
+## v1.1.0
+- **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
+
+    
+  - Add json read and write utility based on circular-json - [c31081e]( https://github.com/royriojas/flat-cache/commit/c31081e ), [Jean Ponchon](https://github.com/Jean Ponchon), 28/07/2016 10:58:17
+
+    
+- **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

+
+The [UNIX command](http://en.wikipedia.org/wiki/Rm_(Unix)) `rm -rf` for node.
+
+Install with `npm install rimraf`, or just drop rimraf.js somewhere.
+
+## API
+
+`rimraf(f, [opts], callback)`
+
+The first parameter will be interpreted as a globbing pattern for files. If you
+want to disable globbing you can do so with `opts.disableGlob` (defaults to
+`false`). This might be handy, for instance, if you have filenames that contain
+globbing wildcard characters.
+
+The callback will be called with an error if there is one.  Certain
+errors are handled for you:
+
+* Windows: `EBUSY` and `ENOTEMPTY` - rimraf will back off a maximum of
+  `opts.maxBusyTries` times before giving up, adding 100ms of wait
+  between each attempt.  The default `maxBusyTries` is 3.
+* `ENOENT` - If the file doesn't exist, rimraf will return
+  successfully, since your desired outcome is already the case.
+* `EMFILE` - Since `readdir` requires opening a file descriptor, it's
+  possible to hit `EMFILE` if too many file descriptors are in use.
+  In the sync case, there's nothing to be done for this.  But in the
+  async case, rimraf will gradually back off with timeouts up to
+  `opts.emfileWait` ms, which defaults to 1000.
+
+## options
+
+* unlink, chmod, stat, lstat, rmdir, readdir,
+  unlinkSync, chmodSync, statSync, lstatSync, rmdirSync, readdirSync
+
+    In order to use a custom file system library, you can override
+    specific fs functions on the options object.
+
+    If any of these functions are present on the options object, then
+    the supplied function will be used instead of the default fs
+    method.
+
+    Sync methods are only relevant for `rimraf.sync()`, of course.
+
+    For example:
+
+    ```javascript
+    var myCustomFS = require('some-custom-fs')
+
+    rimraf('some-thing', myCustomFS, callback)
+    ```
+
+* maxBusyTries
+
+    If an `EBUSY`, `ENOTEMPTY`, or `EPERM` error code is encountered
+    on Windows systems, then rimraf will retry with a linear backoff
+    wait of 100ms longer on each try.  The default maxBusyTries is 3.
+
+    Only relevant for async usage.
+
+* emfileWait
+
+    If an `EMFILE` error is encountered, then rimraf will retry
+    repeatedly with a linear backoff of 1ms longer on each try, until
+    the timeout counter hits this max.  The default limit is 1000.
+
+    If you repeatedly encounter `EMFILE` errors, then consider using
+    [graceful-fs](http://npm.im/graceful-fs) in your program.
+
+    Only relevant for async usage.
+
+* glob
+
+    Set to `false` to disable [glob](http://npm.im/glob) pattern
+    matching.
+
+    Set to an object to pass options to the glob module.  The default
+    glob options are `{ nosort: true, silent: true }`.
+
+    Glob version 6 is used in this module.
+
+    Relevant for both sync and async usage.
+
+* disableGlob
+
+    Set to any non-falsey value to disable globbing entirely.
+    (Equivalent to setting `glob: false`.)
+
+## rimraf.sync
+
+It can remove stuff synchronously, too.  But that's not so good.  Use
+the async API.  It's better.
+
+## CLI
+
+If installed with `npm install rimraf -g` it can be used as a global
+command `rimraf <path> [<path> ...]` which is useful for cross platform support.
+
+## mkdirp
+
+If you need to create a directory recursively, check out
+[mkdirp](https://github.com/substack/node-mkdirp).
