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 🙏

Readme

Adict – Ordered Dictionary

OrderedDict is a data structure that preservers order of inserted keys. And is a sub-class of a regular object/dictionary. In addition it provides couple of convenient methods to push elements to start or end of a dict.

As an example: this data structure can be used to implement LRU-cache.

let OrderedDict = require("adict");

let dict = new OrderedDict();

dict.set(1, 2);
  • Small 538b min and gzip
  • Zero dependencies
  • O(1) runtime complexity for all operations

API

OrderedDict

OrderedDict is a data structure that preservers order of inserted keys. And is a sub-class of a regular object/dictionary. Implementation is inspired by python's OrderedDict and this particular gist: https://gist.github.com/joequery/12332f410a05e6c7c949

Kind: class

let dict = new OrderedDict();

orderedDict.set(key, value) ⇒ OrderedDict

Add a new key-value pair to an ordered dict.

Kind: instance method of OrderedDict

| Param | Type | | ----- | ------------------------------------------ | | key | string | number | | value | any |

orderedDict.delete(key) ⇒ boolean

Delete a key from an ordered dict.

Kind: instance method of OrderedDict

| Param | Type | | ----- | ------------------------------------------ | | key | string | number |

orderedDict.clear() ⇒ undefined

Clear ordered dict.

Kind: instance method of OrderedDict

orderedDict.get(key) ⇒ any | undefined

Retrieve a key from an ordered dict.

Kind: instance method of OrderedDict

| Param | Type | | ----- | ------------------------------------------ | | key | string | number |

orderedDict.has(key) ⇒ boolean

Check if key exists in an ordered dict.

Kind: instance method of OrderedDict

| Param | Type | | ----- | ------------------------------------------ | | key | string | number |

orderedDict.pop() ⇒ undefined | any

Remove and return last element from an ordered dict.

Kind: instance method of OrderedDict

orderedDict.shift() ⇒ undefined | any

Remove and return first element from an ordered dict.

Kind: instance method of OrderedDict

orderedDict.toStart(key) ⇒ boolean

Move an existing element to the start of an ordered dict.

Kind: instance method of OrderedDict

| Param | Type | | ----- | ------------------------------------------ | | key | string | number |

orderedDict.toEnd(key) ⇒ boolean

Move an existing element to the end of an ordered dict.

Kind: instance method of OrderedDict

| Param | Type | | ----- | ------------------------------------------ | | key | string | number |

orderedDict.keys() ⇒ Iterator

Returns new Iterator object that contains all keys of an ordered dict.

Kind: instance method of OrderedDict

orderedDict.values() ⇒ Iterator

Returns new Iterator object that contains all values of an ordered dict.

Kind: instance method of OrderedDict
