http-cache driver for x-ray.
Uses superagent-cache for caching.
See it's documentation for supported caching drivers.
npm install x-ray-http-cache --save
var httpCache = require('x-ray-http-cache');
// using redis for caching
var redisModule = require('cache-service-redis');
var redisCache = new redisModule({
redisUrl: 'http://localhost:6379'
});
var Xray = require('x-ray');
var x = Xray()
.driver(httpCache({
driver: redisCache,
cacheWhenEmpty: false,
expiration: 86400, // 24 hours
// Optional: provide own superagent instance
// superagent: require('superagent')
}));
x('http://google.com', 'title')(function(err, str) {
console.log('Google', str);
// close connection to redis when finished
redisCache.db.quit();
});It's currently not possible to determine whether or not to throttle based on cache.
However if you are sure the cache is already populated you can reset throttling using:
x.throttle(Infinity, 0);MIT
