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

Bysykkel status

Dette er en veldig enkel konsoll-app for å liste status over alle bysykkel-stasjoner i Oslo.

Appen henter data fra det offisielle API-et og viser det i konsollet i et tabulert oppsett med repeterende overskrifter.

Systemkrav

Applikasjonen baserer seg på Node.JS, og benytter bibliotekene request og request-promise-native.

Installasjon

For å installere kjører du følgende kommandoer i konsollet ditt i den mappen du vil installere:

git clone https://github.com/hakash/bysykkel.git .
npm i

Kjøring av appen

npm start

Andre muligheter

Filene BikeshareFeed.js, Stations.js, StationDataFetcher.js og StationDataPrinter.js er laget for å kunne importere i forskjellige typer systemer. Om du ønsker å bygge en web-visning, en CSV-export eller noe helt annet, så kan du bruke disse komponentene for å gjøre det.

Så lenge API-et du kobler på støtter GBFS strukturerte data og presenterer en fil for autodiscover, så skal BikeshareFeed kunne hente data for deg.

Eksempel på å exportere CSV

Dette eksempelet gjør en liten endring på eksempelfila som ligger ved i prosjektet, ved å skifte til skriving av CSV til fil, fremfor tabulert skriving til terminal. Forskjellene er import av fs-pakken, defineringen av et filnavn, samt bruken av fs.writeFileSyncfremfor console.log.

const BikeshareFeed = require("./BikeshareFeed");
const fs = require("fs");

const autodiscoverUrl = "https://gbfs.urbansharing.com/oslobysykkel.no/gbfs.json";
const fileName = "output.csv";

const bf = new BikeshareFeed(autodiscoverUrl,"testcompany","testapp");

bf.on("ready",(err) => {
    if(err) {
        console.log(err);
        return;
    }
    fs.writeFileSync(fileName, bf.csv());
});

bf.loadFeed();

Eksempel på async/await

BikeshareFeed støtter også async/await fremfor callbacks. Samme eksempel som over, men i moderne drakt.

const BikeshareFeed = require("./BikeshareFeed");
const fs = require("fs");

const autodiscoverUrl = "https://gbfs.urbansharing.com/oslobysykkel.no/gbfs.json";
const fileName = "output.csv";

async function run() {
    const bf = new BikeshareFeed(autodiscoverUrl,"testcompany","testapp");

    try {
        await bf.lodFeed();
        fs.writeFileSync(fileName, bf.csv());
    }
    catch(err) {
        if(err) {
            console.log(err);
        }
    }
}

run();

Lykke til!
