MIGRATION GUIDE :construction:

We have dropped callback support in node-cache and you should migrate to our sync-style api!

If you cannot refactor right now, you can turn on legacy callback support by enabling the enableLegacyCallbacks option. Eg: const cache = new NodeCache({ enableLegacyCallbacks: true })

But we strongly recommend to refactor your code to use the sync-api because we will drop official callback support in Versions v6.x and onwards.

If your code currently looks like this:

cache.get("my-key", function(err, value) {
  if (err) {
     // ...
  }

  // double equal checks for null and undefined
  if (value != null) {
    // hmm.... nothing here :(
  }

  // do something with value
});

it should be rewritten to:

const value = cache.get("my-key");

// double equal checks for null and undefined
if (value != null) {
  // hmm.... nothing here :(
}

// do something with value

• Upgrade lodash to version 4.17.15 to avoid security issues

• Add options.promiseValueSize for promise value. Thanks to Ryan Roemer for the pull [#84]
• Added option deleteOnExpire
• Added DefinitelyTyped Typescript definitions. Thanks to Ulf Seltmann for the pulls [#90] and [#92]
• Thanks to Daniel Jin for the readme fix in pull [#93]
• Optimized test and ci configs.

• fix internal check interval for node < 0.10.25, thats the default node for ubuntu 14.04.
  Thanks to Jimmy Hwang for for the pull #78;
• added more docker tests

• Added tests for different key types
• Added key validation (must be string or number)
• Fixed .del bug where trying to delete a number key resulted in no deletion at all.

• Updated tests to mocha
• Fixed .ttl bug to not delete key on .ttl( key, 0 ). This is also relevant if stdTTL=0.
  This causes the breaking change to 4.0.0.

• Updated lodash to 4.x.
• optimized grunt
• updated dependencies
• no more compiled code in the repo
• dropped travis test for node 0.6 and 0.8 because of failing grunt build

Added method getTtl to get the time when a key expires. See #49

• Added option errorOnMissing to throw/callback an error o a miss during a .get( "key" )
  Thanks to David Godfrey for the pull #45
• Added docker files and a script to run test on different node versions locally

• unref() the checkperiod timer
• optimized travis.yml

added .keys() method to list all existing keys.

fix for setting numeric values. Thanks to kaspars + optimized key ckeck.

Small change for better ttl handling

Made callbacks optional. So it's now possible to use a syncron syntax. The old syntax should also work well.

Added events set, del, expired and ´flush´ to nodecache to react on chaning data.
