In this guide I will show you how to use Firebase, React, and Ant Design as building blocks to build functional, high-fidelity web applications. To illustrate this, we’ll go through an example of building a todo list app. These days, there are so many tools available for web development that it can feel paralyzing. Which server should you use? What front-end framework are you going to choose? Usua
17 JavaScript / node.js performance coding tips to make applications faster Though JavaScript has the highest number of developers in its community with respect to any other language on earth at this moment; there are a lot of misconceptions, shallow knowledge, bad assumptions among the community members. In this article we have come up with a list of tips, which can make your javascript applicati
Moderator note: Please resist the urge to edit the code or remove this notice. The pattern of whitespace may be part of the question and therefore should not be tampered with unnecessarily. If you are in the "whitespace is insignificant" camp, you should be able to accept the code as is. Is it ever possible that (a== 1 && a ==2 && a==3) could evaluate to true in JavaScript? This is an interview qu
We are pleased to announce version 5.0.0 of Angular, pentagonal-donut. This is a major release containing new features and bugfixes. This release continues our focus on making Angular smaller, faster, and easier to use. Here’s a breakdown of some of the biggest changes in v5. For the full list, please see the changelog. Build OptimizerAs of 5.0.0, production builds created with the CLI will now ap
There are a set of rules to keep in mind: Perform work in a feature branch. Why: Because this way all work is done in isolation on a dedicated branch rather than the main branch. It allows you to submit multiple pull requests without confusion. You can iterate without polluting the master branch with potentially unstable, unfinished code. read more... Branch out from develop Why: This way, you can
先日行われたFacebookの開発者向けイベント「F8」で、React Fiberの発表が行われていました。 といっても、React関連の新しいプロダクトが発表されたというわけではなく、Reactが一から書き直されたということのようです。 ReactはなぜFiberで書き直されねばならなかったのか?Fiberが解決しようとした課題は何なのか? その答えを聞くために、React Fiber現状確認というブログエントリで大変詳細にFiberの事を解説されていた小林徹 (Twitter: @koba04)さんに、実際のところを詳しく伺ってきました。 React Fiberとはなんなのか、そしてReactの将来像を探ってみます。 React Fiberとは? 白石 React Fiberってなんですか?まずは概要を教えてください。 小林 Facebookが先日のF8カンファレンスで発表した、Rea
Angular version 4.0.0 - invisible-makeover - is now available. This is a major release following our announced adoption of Semantic Versioning, and is backwards compatible with 2.x.x for most applications. We are very excited to share this release with the community, as it includes some major improvements and functionality that we have been working on for the past 3 months. We’ve worked hard to ma
jQuery-File-Upload を利用した分割アップロードサンプル 今回は jQuery-File-Upload の分割アップロード機能 (Chunked file upload) が使えそうという事で、あちこちを見ながらカスタマイズして WEB サーバに設置してみました。 WEB サーバは下記 Nginx 1.10.1 と PHP 7.0.8 で構成していて関連する設定値は下記の通りデフォルトのままなので、その状態でも動作するように設定しています。 Nginx のアップロード上限はデフォルトの 1MB (client_max_body_size) php.ini に設定したアップロード上限はデフォルトの 2MB (upload_max_filesize) とりあえずサンプルファイル一式は zip にまとめてアップしました。 中身は下記のようになっていて “upload.html”
Welcome to my modern JavaScript stack tutorial: JavaScript Stack from Scratch. 🎉 This is the V2 of the tutorial, major changes happened since the 2016 release. Check the Change Log! This is a straight-to-the-point guide to assembling a JavaScript stack. It requires some general programming knowledge, and JavaScript basics. It focuses on wiring tools together and giving you the simplest possible e
Build complex rules, serialize them as JSON, share them between front-end and back-end Why use JsonLogic? If you’re looking for a way to share logic between front-end and back-end code, and even store it in a database, JsonLogic might be a fit for you. JsonLogic isn’t a full programming language. It’s a small, safe way to delegate one decision. You could store a rule in a database to decide later.
In the JavaScript community, engineers share hundreds of thousands of pieces of code so we can avoid rewriting basic components, libraries, or frameworks of our own. Each piece of code may in turn depend on other pieces of code, and these dependencies are managed by package managers. The most popular JavaScript package manager is the npm client, which provides access to more than 300,000 packages
