Package Exports

cache4js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cache4js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

cache4js

A simple and easy-to-use cache module with auto recycle for js/nodejs.

##How to use ?
1、install
npm install cache4js
2、init

var CACHE_TYPE = {
    TEST_CACHE: {RECYCLE_TIME: 1000 * 5, SHOW_LOG: true},
    TEST_CACHE_1: {RECYCLE_TIME: 1000 * 10, SHOW_LOG: true}
};
var cache = require('cache4js')(CACHE_TYPE);

for global use:

global.CACHE_TYPE = {
    TEST_CACHE: {RECYCLE_TIME: 1000 * 5, SHOW_LOG: true},
    TEST_CACHE_1: {RECYCLE_TIME: 1000 * 10, SHOW_LOG: true}
};
global._Cache = require('cache4js')(CACHE_TYPE);

3、common use:

cache.add(CACHE_TYPE.TEST_CACHE, 1, {value:'abc'});
cache.add(CACHE_TYPE.TEST_CACHE_1, 1, {value:'abc'});

var obj = cache.get(CACHE_TYPE.TEST_CACHE, 1);
console.log(obj.value); //print:abc

setTimeout(function () {
    var obj = cache.get(CACHE_TYPE.TEST_CACHE, 1);
    console.log(obj && obj.value || 'null'); //print:null,already recycled in 5s
}, 6000);

4、exact time use

var obj = cache.get(CACHE_TYPE.TEST_CACHE, 1);
// time in ms
if (obj && obj.__time + 5000 > Date.now()) {
    // do sth
    console.log(obj.value);
}

5、for multi-use

var CACHE_TYPE = {
    TEST_CACHE: {RECYCLE_TIME: 1000 * 5, SHOW_LOG: true},
    TEST_CACHE_1: {RECYCLE_TIME: 1000 * 10, SHOW_LOG: true}
};
var cache1 = require('cache4js')(CACHE_TYPE);
var cache2 = require('cache4js')(CACHE_TYPE);

cache1 and cache2 are totally seperated.

##API 1、config type

var CACHE_TYPE = {
    TEST_CACHE: {RECYCLE_TIME: 1000 * 5, SHOW_LOG: true},
    TEST_CACHE_1: {RECYCLE_TIME: 1000 * 10, SHOW_LOG: true,VALID_CHECK:false}
};
var cache = require('cache4js')(CACHE_TYPE);

RECYCLE_TIME: the life time of the special cache obj,count in milliseconds.Default:600000ms;
-------------------------------------------|------------------------------------------------------------------------------------------------------------
SHOW_LOG: it will show the log when the cache obj be recycled only if this config is true;
-------------------------------------------|------------------------------------------------------------------------------------------------------------
VALID_CHECK: it will not recycle anything only if this config is false and has no RECYCLE_TIME config;
-------------------------------------------|------------------------------------------------------------------------------------------------------------
2、interface

add(type,key,obj);   
get(type,key);   
del(type,key);   
addType(type);   
getType(type);   
delType(type);   
clearType(type);
