GitHub - mobxjs/mobx-state-tree: Full-featured reactive state management without the boilerplate
Technically speaking, mobx-state-tree (also known as MST) is a state container system built on MobX, a functional reactive state library. This may not mean much to you, and that’s okay. I’ll explain it like this: MobX is a state management "engine", and MobX-State-Tree gives it structure and common tools you need for your app. MST is valuable in a large team but also useful in smaller applications
How to write a codemod · Ramana Venkata
Solution: In this section of this tutorial, I will teach to how to use ASTExplorer and arrive at the solution to our problem incrementally. Whenever I try to solve a problem, my first approach is to break down the problem into smaller pieces and solve them one by one. To explain this bit more, you don’t need to solve problem in its full generality in the first go, solve for a specific case it may
GitHub - YahooArchive/xss-filters: Secure XSS Filters.
More Secure. Context-dependent output filters that are developer-friendly. It is safe to apply these filters like so: document.write("<a href=" + xssFilters.uriInUnQuotedAttr(url) + ">" + xssFilters.uriInHTMLData(url) + "</a>"); In this example, the traditional wisdom of blindly escaping some special html entity characters (& < > ' " `) would not stop XSS (e.g., when url is equal to javascript:ale

Async iterators and generators
Streaming fetches are supported in Chrome, Edge, and Safari, and they look a little like this: async function getResponseSize(url) { const response = await fetch(url); const reader = response.body.getReader(); let total = 0; while (true) { const { done, value } = await reader.read(); if (done) return total; total += value.length; } } This code is pretty readable thanks to async functions (here's a
Rewriting Javascript : Replacing the Switch Statement
The humble switch statement, it exists in almost every programing language and javascript is no exception. The switch statement allows for cleaner organization of code when a large number of evaluations needs to be made. But the switch poses several problems, which I think are best shown through an example. The ProblemBelow we see a standard switch statement wrapped in a function. This statement w
2017-04-17のJS: prettier 1.0、MSEdge 15、Twitter Liteのパフォーマンスチューニング
JSer.info #327 - JavaScriptの整形ツールであるprettier 1.0がリリースされました。 Releasing Prettier 1.0 Go言語のgofmtやReasonのrefmtのようなコード整形ツールです。 prettierは言語側が提供するツールではないのであくまでopinionatedな整形にすることで設定項目を少なくしています。1.0では利用者でも意見が割れやすいセミコロンやタブ/スペースなどについてはオプションが追加されています。 (それでもオプションは10個以下なのでかなり少ないです。) JavaScriptは利用者によって書き方が異なることについては、JavaScriptの作者である@BrendanEichが次のように書いてたりもします。 JavaScriptは、癖をゆるさないとか制限がきついなどとは、まるで反対の立場だ。だから、効果的な(e

GitHub - somesocks/vet: A Javascript library for data validation.
version 5 includes several breaking changes from version 4, mostly designed to improve interoperability with TS optional no longer accepts null, just undefined. This is to bring it inline with TypeScript and many other libraries' interpretation of optional values. isShape now converts all T | undefined properties to optional properties in the validator schema type. This eliminates the requirement
