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

@nickadam/kv Build Status

A simple key value database backed by sqlite3

Features

  • Auto-expiring entries
  • Wildcard matching
  • Synchronous and asynchronous formats
  • In-memory database (great for testing)
  • Store and retrieve native objects (no need to serialize)

Installation

npm install @nickadam/kv

Usage

Examples

Sync

const kv = require('@nickadam/kv')('/path/to/file.db')

kv.set('mykey', {stuff: 'things'})

const data = kv.get('mykey')

console.log(data) // {stuff: 'things'}

kv.quit()

Async

const kv = require('@nickadam/kv')('/path/to/file.db')

kv.set('mykey', {stuff: 'things'}, err => {
  if(err) return err

  kv.get('mykey', (err, data) => {
    kv.quit()

    console.log(data) // {stuff: 'things'}
  })
})

Set entries to expire using the ttl option.

kv.set('mykey', {stuff: 'things'}, {ttl: 10}) // expires in 10 seconds

Get a list of values matching keys with the wildcard *.

kv.set('mykey', {stuff: 'things'})

kv.set('yourkey', 100)

const data = kv.get('*key')

console.log(data) // [{stuff: 'things'}, 100]

Get the metadata associated with entries using the metadata option.

kv.set('mykey', {stuff: 'things'})

const data = kv.get('mykey', {metadata: true})

console.log(data)
/*
{
  k: 'mykey',
  v: { stuff: 'things' },
  ttl: -1,
  timestamp: '2021-06-06 12:27:58'
}
*/

Delete entries

kv.del('mykey')
kv.del('mykey', err => {
  // check err and do stuff
})

Use an ephemeral in-memory database with the path :memory:

const kv = require('@nickadam/kv')(':memory:')

More information

* are not permitted in key names.

Expired entries are deleted at startup. For long running applications, a background job will delete expired entries once a minute - so long as you do not execute kv.quit(). Expired entries that have not yet been deleted will not return.

Values are encoded and decoded using JSON.stringify and JSON.parse.

This database was built using these amazing projects:
