config/routes.rb の書き方を見直した – r7kamura – Medium
開発を手伝っている Rails アプリの config/routes.rb の書き方を見直した。 ルール以下のようなガイドラインを設け、これを守るように書き換えた。 resource(s) などの DSL の利用を避けるパスの辞書順に定義するHTTP メソッドの部分だけ特別にインデントする具体例こういう形の、素朴なルーティングがひたすらに羅列されていくコードになる。実際のコードでは数百行以上に及ぶ。基本的に1行に1つのルーティングが定義される。 MyApp::Application.routes.draw do get '/' => 'top_pages#show', as: :top_page delete '/api/applications/:applicaiton_id' => 'api_applications#destroy', as: :application get '/a
Why “Progressive Web Apps vs. native” is the wrong question to ask
Updated October 2022 I wrote this post in back 2016, when Progressive Web Apps were very new. Fast forward to 2022 — PWAs have been embraced by Instagram, Twitter, Tiktok, Pinterest, Telegram and many other brands, enabling fast, reliable, engaging and installable websites. The road here wasn’t easy, and many misconceptions about PWAs stood across: <strike>they only work in Chrome, they can’t be a
Android Oreo takes a bite out of Progressive Web Apps
On August, 21st after the solar eclipse, Google released the final version of Android 8 now known as Android Oreo. The sun wasn’t the only thing that was hidden for a while today, as Progressive Web Apps have acquired new problems. I’ve installed Android 8 on my Google Pixel, and I’ve tested a couple of things regarding websites and PWAs and then I have a couple of bad news to share. Android Insta
A beginner’s guide to Service Workers
This guide is aimed at people who have some experience with HTML, CSS, and JavaScript. It covers the basics of service workers and how to use them without going into too much detail, with the aim of letting you build a prototype as quickly as possible. Once you have a basic demo and understanding then you can look at other resources and the theory of how things work as you need them. What is a ser
A React And Preact Progressive Web App Performance Case Study: Treebo
Treebo is India’s top rated budget hotel chain, operating in a segment of the travel industry worth $20 billion. They recently shipped a new Progressive Web App as their default mobile experience, initially using React and eventually switching to Preact in production. What they saw compared to their old mobile site was a 70%+ improvement in time to first paint , 31% improvement in time-to-interact
Gemfile の書き方を見直した - r7kamura - Medium
Gemfile を記述するときの自分のルールを見直したので言語化しておく。 ルール決まった順序で定義しなければいけない Gem は上部に書く順序に依存しない Gem は名前の辞書順に書くコメントも含めて 1 つの Gem あたりに 1行使うgroup が必要なものは group メソッドを使って下部に書くgroup も辞書順に書くサンプルコード実際のアプリケーションでは、もう少し込みいったコードになるはず。 source "https://rubygems.org"# Fixed order gem "rails", "5.1.4"# Alphabetical order gem "aaa" gem "bbb", "1.2.3" # https://github.com/bbb/bbb/issues/123 gem "ccc"group :xxx do gem "ddd" gem "eee
How We Built Our React Native App
Last year we launched our PWA with an aim to improve the experience of our users on slow and inconsistent network connections. It was the first step towards the quality of products we strive for. We received a very positive response from the community as well as our customers and wanted to replicate the same success for our mobile application too. An ideal mobile application should be an extension
Checklist to Deploy React Native to Production
Many React Native developers came to mobile development from a background of web development (like me). That’s one of the reasons React Native is appealing — it’s so much like the web. But because of this we often have a gap of knowledge, namely around bringing the app to production. The web has its challenges but mobile development has a different set of challenges — challenges we may not necessa
Not so Essential phone
My Nexus 6P is two years old and, as every Android, becoming slower and slower. The battery has degraded too, and now the phone is not holding even half a day of moderate usage. I usually change the phone every two years, and a few weeks ago I started looking for a new one. I’ve had a bad experience with the vendor (Samsung) tweaks in the past, so the stock Android was the must for me. Pixel phone
最高のものを作る
ぼくらの作るものは最高のプロダクトだし、最高のサービスを提供していくぞ！という気持ちは大事だと思う。 目の前のものをなんとかしようとすると、どうしても細かな改善や今やってることと連続した地続きの施策になりがち。 当然それも大事だし、やっていかねばならないんだけどそれだけだとどうしても先細っていく。 あるいはこれをやればここが上向くよね、といろいろなところで妥協してしまう。 でも待ってほしい、そのプロダクトを作り始めたとき、サービスを考えたときに思っていたことはそんなことだったっけ、と思い返してほしい。 ポエム駆動開発だとそこが明文化できるのでよい。でもそうでなくても、思い出せるでしょ？きっと。 メルカリの「GO BOLD」とか、結局のところそういうことなのだと思う。最高のものを、と考えたら細かいことは別で考えればよくて（それはそれで大事なんだけど、それだけじゃいけないということ）。 最高の
JavaScript — from callbacks to async/await
JavaScript is synchronous. This means that it will execute your code block by order after hoisting. Before the code executes, var and function declarations are “hoisted” to the top of their scope. This is an example of a synchronous code: console.log('1')console.log('2')console.log('3')This code will reliably log “1 2 3". Asynchronous requests will wait for a timer to finish or a request to respon
How we refit Foursquare Swarm for the next 12B check-ins
Last week we unveiled Swarm 5.0 on iOS, and today, we’re celebrating two additional milestones: we’re launching Swarm 5.0 for Android and we’ve just hit 12 billion check-ins. We’re really proud of the product we’ve built and our accomplishments, particularly on a day like today. We hope you’ll check it out if you haven’t already. As the product manager on Swarm, my role is to identify the most imp
Going Mobile: Wrapping an existing web application in Cordova/Phonegap
There are many choices to build mobile applications, from native to the growing popularity of hybrid development, with everything in between. In all of these cases, as a developer you would be writing a brand new mobile application from scratch with the ultimate goal of deploying to one the app stores. Let’s say that a company has an existing web application and for reasons we will not debate here
Build crazy queries with ActiveRecord and Arel
Today I have had to fix a rather complex query. Turned into plain old SQL it rendered as : SELECT products.* FROM products WHERE EXISTS ( SELECT prices.* FROM prices WHERE prices.country_code IN ['FR', 'DE'] AND prices.customer_price > 0 AND current_date BETWEEN( COALESCE(prices.valid_from, 'yesterday'::DATE) and COALESCE(prices.valid_to, 'tomorrow'::DATE) ) AND prices.product_id = products.id )Th
Profiling GraphQL
As soon as you put your API in production, people inevitably will come to you at some point and start complaining about slow requests :) At this point it does not matter whether you are exposing REST API or GraphQL or anything else, performance is always an important concern. So starting to think about an API performance early is almost always a good idea. GraphQL has quite a few advantages when i
🍾🚀 webpack 3: Official Release!! 🚀🍾
After we released webpack v2, we made some promises to the community. We promised that we would deliver the features you voted for. Moreover, we promised to deliver them in a faster, more stable release cycle. No more year-long betas, no breaking changes between release candidates. We promised to do you right by you, the community that makes webpack thrive. The webpack team is proud to announce th
amakanのUIの歴史 - r7kamura - Medium
amakan の UI がころころ変わっている様子を紹介します。 2016年夏amakan は 2016年6月に開発を始めました。最初の段階では書籍データの収集ロジックの開発に注力しようと考え、UI には有料の CSS テーマを購入して利用していました。Twitter Bootstrap を利用してマテリアルデザインで管理画面をつくろう的な CSS テーマを選択しました。 2016年夏のトップページ2016年冬用意された部品では限界があると考え、これまで利用してきた CSS テーマを捨て、自分で適当な CSS を書いて UI をつくっていく体制に移行しました。この変更と同時に、リンクをクリックすると画面内の必要な部分だけが書き換わる、所謂 Single-Page Application のような形に移行しました。 2016年冬のトップページ2017年春これまでの UI では、おすすめの作品
