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 🙏

A storage with a customizable item lifetime and capacity with a localStorage-like API

class VolatileStorage

const VolatileStorage = require('@axtk/volatile-storage');

const storage = new VolatileStorage({
    storage: window.localStorage,
    maxAge: 60000, // in milliseconds
    capacity: 100
});

await storage.setItem('x', 1);
await storage.setItem('status', 'done', {maxAge: 120000});

let x = await storage.getItem('x');

new VolatileStorage(props?)

  • props?: object
  • props.storage?: Storage | async<Storage>
    • An external storage instance with a localStorage-like API (like window.localStorage itself, window.sessionStorage, or localForage) where all values will actually be stored.
    • Default: in-memory storage.
  • props.maxAge?: number
    • A storage entry lifetime in milliseconds. (A stored value may linger on the storage after its lifetime elapses until the next interaction with the storage reveals the value has expired and removes it.)
    • Default: Infinity.
  • props.capacity?: number
    • A maximum number of entries on the storage. When the number of entries reaches the capacity value and a new item is added to the storage, the first added item is removed from the storage to maintain the capacity.
    • Default: Infinity.
  • props.ns?: string
    • A storage entry key namespace. It can be useful to isolate multiple instances of VolatileStorage sharing the same external storage (like window.localStorage).
    • Default: ''.
  • props.version?: string | number
    • A version, or a revision identifier, of the storage. Changing this value will expire values stored in an external storage (like window.localStorage) under a different version.
    • Default: undefined.

The methods of the VolatileStorage class are asynchronous versions of the Storage methods.
