URL key-value cache and store.
Node.js >= 0.10
is required. To install, type this at the command line:
npm install urlcache --save-dev
Note: Node.js v0.10 will need a Promise
polyfill.
var UrlCache = require("urlcache");
var cache = new UrlCache(options);
Note: all instances of url
can be either a String
or a url.parse()
-compatible Object
.
Removes url
from cache. If url
is not defined, all cached key value pairs will be removed.
Returns a Promise
with the stored value of url
. If no such value exists, the promise will be rejected.
cache.get("url").then(function(value) {
console.log(value); //-> "value"
});
cache.get("unstored").catch(function(error) {
// not in cache (or value is a rejected Promise)
});
Stores value
(any type) into url
key. Optionally, define expiryTime
to override options.expiryTime
.
cache.set("url", {"key":"value"});
cache.get("url").then(function(value) {
console.log(value); //-> {"key":"value"}
});
cache.set("url", new Promise(function(resolve, reject) {
// set value after some delayed event
setTimeout(function() {
resolve("value");
}, 500);
});
cache.get("url").then(function(value) {
console.log(value); //-> "value"
});
