redis-cache v0.2.1
redis-cache
Super simple redis-based single-lookup caching for Node.js designed as a temporary storage for Hook.io
Install
$ npm install redis-cache
Usage
Example using Hook.io (obviously very simplified)
hook-one.js
var cache = require('redis-cache');
cache.init('redis://...');
hook.emit('doSomething', 'data', function(err, key) {
if (err) {...}
cache.fetch(key, function(err, reallyBigResult) {
if (err) {...}
// ...
});
});
hook-two.js
var cache = require('redis-cache');
cache.init('redis://...');
hook.on('*::doSomething', function(data, callback) {
doSomething(data, function(err, reallyBigResult) {
if (err) {...}
cache.store(reallyBigResult, function(err, key) {
if (err) {...}
callback(null, key);
});
});
});
Configuration
The redisCache.init
method can take a redis url as a paramter as shown above, or a config object.
{
"url": "redis://...",
"expire": 600
}
The expire value is how long (in seconds) a value is held in cache.
