Simple in-memory file cache.

Installation

npm install phialcash

Example

var co = require('co');
var fs = require('mz/fs'); // or any generator friendly file system library
var config = {
  fsLibrary: fs,
  fsExistsMethod: 'exists',
  fsReadFileMethod: 'readFile'
};
var fc = require('phialcash');
fc = new fc(config);

var filePath = './tests/file.fixture.txt';
var fileName = 'file.fixture.txt';

co(function* () {
  yield fc.cache(filePath, fileName); // Caches file at filePath.

  if (fc.has(fileName)) { // Checks if there is a cached version of the file.
    yield fc.get(fileName); // Returns the cached version of the file.
  }

  fc.has(fileName); // true.

  fc.clear(); // Empties the cache.

  fc.has(fileName); // false.
})();

API

new fc(config)

phialcash expects a generator friendly file system library.

• config.fsLibrary - Reference to the file system library
• config.fsExistsMethod - String representation of the method name that checks if a file exists
• config.fsReadFileMethod - String representation of the method name that reads a file

fc.cache(filePath, fileName)

Caches the file at filePath. filePath, and fileName are string.

fc.has(fileName)

Returns true if there is a cached version of fileName; otherwise, returns false. fileName must be a file name string.

fc.get(fileName)

Returns the fileName's contents from memory. fileName must be a file name string.

fc.clear()

Clears the cache.
