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 🙏

Have you ever been annoyed by how complicated it can be to map promises to the actual values you need?

const myPromise = Promise.resolve({ 
    house: { 
        roof: { 
            shingles: 576 
        }, 
        cellar: { 
            size: 40 
        }, 
        livingRoom: { 
            chair: { 
                height: 5 
            }, 
            sofa: { 
                width: 10 
            }
        }
    }
})

const house = myPromise.then(data => data.house)

const livingRoom = house.then(house => house.livingRoom)

const chairHeight = await livingRoom.then(livingRoom => livingRoom.chairHeight)

What if it was possible to automate this as much as possible?

Welcome to eager

const data = eager(myPromise)

const house = data.house

const livingRoom = house.livingRoom

const chairHeight = await livingRoom.chairHeight

Why is this useful?

Defining skeletons in react must currently be done at the highest level where a promise is resolved:

async function House() {
    const { house } = await fetchHouseData()

    return (
        <>
            <Roof shingles={house.roof.shingles} />
            <LivingRoom>
                <Chair height={house.livingRoom.chair.height} />
                <Sofa width={house.livingRoom.sofa.width} />
            </LivingRoom>
            <Cellar size={house.cellar.size} />
        </>
    )
}

function HouseSkeleton() {
    return (
        <>
            <RoofSkeleton />
            <LivingRoom>
                <ChairSkeleton />
                <SofaSkeleton />
            <CellarSkeleton />
        </>
    )
}

This can become tedious because the skeletons must be defined separately from the main rendering logic so a lot of structure must be duplicated and kept in sync.

Instead, with eager, it is possible to write

function House() {
    const { house } = eager(fetchHouseData())

    return (
        <>
            <Suspense fallback={<RoofSkeleton />}>
                <Roof shingles={house.shingles} />
            </Suspense>
            <LivingRoom>
                <Suspense fallback={<ChairSkeleton />}>
                    <Chair height={house.livingRoom.chair.height} />
                </Suspense>
                <Suspense fallback={<SofaSkeleton />}>
                    <Sofa width={house.livingRoom.sofa.width} />
                </Suspense>
            </LivingRoom>
            <Suspense fallback={<CellarSkeleton />}>
                <Cellar size={house.cellar.size} />
            </Suspense>
        </>
    )
}

which can be simplified much by using a clever skeleton builder component.
