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

pail

Test JavaScript Style Guide

DAG based key value store. Sharded DAG that minimises traversals and work to build shards.

Install

npm install @web3-storage/pail

Usage

import { put, get, del } from '@web3-storage/pail'
import { ShardBlock } from '@web3-storage/pail/shard'
import { MemoryBlockstore } from '@web3-storage/pail/block'

// Initialize a new bucket
const blocks = new MemoryBlockstore()
const init = await ShardBlock.create() // empty root shard
await blocks.put(init.cid, init.bytes)

// Add a key and value to the bucket
const { root, additions, removals } = await put(blocks, init.cid, 'path/to/data0', dataCID0)

console.log(`new root: ${root}`)

// Process the diff
for (const block of additions) {
  await blocks.put(block.cid, block.bytes)
}
for (const block of removals) {
  await blocks.delete(block.cid)
}

Batch operations

If adding many multiple items to the pail together, it is faster to batch them together.

import { put, get, del } from '@web3-storage/pail'
import { ShardBlock } from '@web3-storage/pail/shard'
import { MemoryBlockstore } from '@web3-storage/pail/block'
import * as Batch from '@web3-storage/pail/batch'

// Initialize a new bucket
const blocks = new MemoryBlockstore()
const init = await ShardBlock.create() // empty root shard
await blocks.put(init.cid, init.bytes)

const batch = await Batch.create(blocks, init.cid)

// items is an array of `{ key: string, value: CID }` - the items to add to the pail
for (const item of items) {
  await batch.put(item.key, item.value)
}

const { root, additions, removals } = await batch.commit()

console.log(`new root: ${root}`)

// Process the diff
for (const block of additions) {
  await blocks.put(block.cid, block.bytes)
}
for (const block of removals) {
  await blocks.delete(block.cid)
}
