Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MongoDB standalone caching library for Node.JS and also cache engine for recacheman.

Instalation

$ npm install recacheman-mongo

Usage

var CachemanMongo = require('recacheman-mongo');
var cache = new CachemanMongo();

// set the value
cache.set('my key', { foo: 'bar' }, function (error) {

  if (error) throw error;

  // get the value
  cache.get('my key', function (error, value) {

    if (error) throw error;

    console.log(value); //-> {foo:"bar"}

    // delete entry
    cache.del('my key', function (error){
      
      if (error) throw error;

      console.log('value deleted');
    });

  });
});

API

CachemanMongo([options])

Create cacheman-mongo instance. options are mongo valid options including port, host, database and collection.

var options = { 
  port: 9999,
  host: '127.0.0.1',
  username: 'beto',
  password: 'my-p@ssw0rd'
  database: 'my-cache-db',
  collection: 'my-collection',
  compression: false
};

var cache = new CachemanMongo(options);

You can also pass a valid mongodb connection string as first arguments like this:

var options = {
  collection: 'account'
};

var cache = new CachemanMongo('mongodb://127.0.0.1:27017/blog', options);

Or pass a mongodb db instance directly as client:

MongoClient.connect('mongodb://127.0.0.1:27017/blog', function (err, db) {
  var cache = new CachemanMongo(db, { collection: 'account' });

  // or
  cache = new CachemanMongo({ client: db, collection: 'account' });
});

Cache Value Compression

MongoDB has a 16MB document size limit, and, currently, does not have built in support for compression. You can enable cache value compression for large Buffers by setting the compression options to true, this will use the native node zlib module to compress with gzip. It only compresses Buffers because of the complexity in correctly decompressing and deserializing the variety of data structures and string encodings.

Thanks to @Jared314 for adding this feature.

var cache = new Cache({ compression: true });
cache.set('test1', Buffer.from("something big"), function (err) {...});

cache.set(key, value, [ttl, [fn]])

Stores or updates a value.

cache.set('foo', { a: 'bar' }, function (err, value) {
  if (err) throw err;
  console.log(value); //-> {a:'bar'}
});

Or add a TTL(Time To Live) in seconds like this:

// key will expire in 60 seconds
cache.set('foo', { a: 'bar' }, 60, function (err, value) {
  if (err) throw err;
  console.log(value); //-> {a:'bar'}
});

cache.get(key, fn)

Retreives a value for a given key, if there is no value for the given key a null value will be returned.

cache.get('foo', function (err, value) {
  if (err) throw err;
  console.log(value);
});

cache.del(key, [fn])

Deletes a key out of the cache.

cache.del('foo', function (err) {
  if (err) throw err;
  // foo was deleted
});

cache.clear([fn])

Clear the cache entirely, throwing away all values.

cache.clear(function (err) {
  if (err) throw err;
  // cache is now clear
});
