Adding tags functionality to memcached. Using node-memcached module by 3rd-Eden.
npm install memcacher
Use it like you've used memcached module by 3rd-Eden. Memcacher just adds one more option to method set - tags. Take a look at such situation: Let's say we have a list of posts, and when we delete one post, we don't want it to appear on our list of all posts, right? That's where tags come handy. Check out this example:
Memcacher = require 'memcacher' Client = new Memcacher ['127.0.0.1:11211'] Client.set 'first-post', 'first title', 2592000, ['first-post-tag'], -> Client.set 'second-post', 'second title', 2592000, ['second-post-tag'], -> Client.set 'posts', JSON.stringify(['first title', 'second title']), 2592000, ['first-post-tag', 'second-post-tag'], -> # all records are saved # now, if you will remove record with key "first-post", all records with tag "first-post-tag" will be removed Client.del 'first-post', -> # if you will try to get record with key "posts", it will be false Client.get 'posts', (err, value) -> # value is not ['first title', 'second title'] # it is false # and you should calculate your list of posts again, excluding deleted ones
Tests made using mocha. Run them by doing this:
cd tests && mocha *
