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 🙏

Node.jsで都バスの接近情報のページを解析します

Readme

Node.js 用都バス接近情報解析モジュール

フィーチャーフォン(ガラケー)向けの都バス車両接近情報のページをスクレイピングして、バス接近情報を取得します。

ガラケー向けのページを使っているのは、軽量(スマホ向けの 1/10 程度)かつ解析が楽だからです。

次のように接近情報を取得できます。

使い方

バス停 ID を指定する方法

次のようにバス停 ID(busStopId)、のりば ID(poleId)、路線 ID(routeId)を指定します。

const tobus = require('tobus');

tobus
  .approaching({
    busStopId: 1130,
    poleId: 3,
    routeId: 6
  })
  .then(a => {
    console.log(a);
  });

// [ { name: '西麻布', bus: [ 0 ] },
//   { name: 'EXシアター六本木前', bus: [] },
//   { name: '六本木駅前', bus: [ 7 ] },
//   { name: '六本木四丁目', bus: [ 10 ] },
//   { name: '六本木一丁目駅前', bus: [] },
//   { name: '5つ前の停留所', bus: [] },
//   { name: '溜池', bus: [] } ]

それぞれの ID は、都バス車両接近情報のページからバス停を検索してその URL から取得します。例えば、都01 渋谷駅前行の西麻布のバス停の URL は次の通りです。

https://tobus.jp/blsys/navim?LCD=&func=fap&bs=1130&VCD=SelectStopPole&ECD=resultapproach&RTMCD=6&pl=3

このうち、bs=1130がバス停 ID、RTMCD=6が路線 ID、pl=3がのりば ID です。

URL を指定する方法

接近情報の URL を直接指定することもできます。

const tobus = require('tobus');

tobus
  .approaching({
    url:
      'https://tobus.jp/blsys/navim?LCD=&func=fap&bs=1130&VCD=SelectStopPole&ECD=resultapproach&RTMCD=6&pl=3'
  })
  .then(a => {
    console.log(a);
  });

// [ { name: '西麻布', bus: [ 0 ] },
//   { name: 'EXシアター六本木前', bus: [] },
//   { name: '六本木駅前', bus: [ 7 ] },
//   { name: '六本木四丁目', bus: [ 10 ] },
//   { name: '六本木一丁目駅前', bus: [] },
//   { name: '5つ前の停留所', bus: [] },
//   { name: '溜池', bus: [] } ]
