diskstore

a basic local cache implementation

Introduction

A basic file cache implementation. It just providers low-level APIs (get, set, delete) to allow you read & atomic write from file cache. You can also create your implementation by inheriting or wrapping it.

Install

$ npm install diskstore --save

APIs

• new DiskStore(options)
  • {String} cacheDir - root cache dir
• * get(relativePath) read data from relativePath if the file exists.
  • {String} relativePath - file path relative to root cache dir
• * set(relativePath, data) write data to relativePath
  • {String} relativePath - file path relative to root cache dir
  • {Buffer|String} data - the data
• * delete(relativePath) delete the file
  • {String} relativePath - file path relative to root cache dir

Usage

const diskStore = new DiskStore({
  cacheDir: '/path/cache',
});
yield diskStore.set('a/b/c', 'c');
let data = yield diskStore.get('a/b/c');
assert.deepEqual(data, new Buffer('c'));

yield diskStore.delete('a/b/c');
data = yield diskStore.get('a/b/c');
assert(data === null);
