GitHub - jayu/rev-dep: Dependency analysis and optimization toolkit for modern JavaScript and TypeScript codebases. Enforce dependency graph hygiene and remove unused code with a very fast CLI.
As codebases scale, maintaining a mental map of dependencies becomes impossible. Rev-dep is a high-speed static analysis tool designed to enforce architecture integrity and dependency hygiene across large-scale JS/TS projects. Think of Rev-dep as a high-speed linter for your dependency graph. Consolidate fragmented, sequential checks from multiple slow tools into a single, high-performance engine.

Cleaning up import paths in JS/TS packages - Socket
Cleaning up import paths in JS/TS packagespackage.json contains a local aliasing mechanism for import paths called "imports" it satisfies many use cases without tooling specific solutions like tsconfig.json Applications and libraries grow over time. In JavaScript and TypeScript these lead to large amounts of files over time due to various conventions and linting rules that may be held in a code ba
ArrowJS — The first UI framework for the agentic era
The first UI framework for the agentic era A tiny, blazing-fast, zero dependency, type-safe framework with no build step required. ArrowJS ships with the ability to isolate component logic inside Web Assembly sandboxes while rendering full inline DOM directly in your app — no iframes, no pre-defined UI components.

GitHub - LibPDF-js/core: A modern PDF library for TypeScript. Parse, modify, and generate PDFs with a clean, intuitive API.
A modern PDF library for TypeScript. Parse, modify, and generate PDFs with a clean, intuitive API. Beta Software: LibPDF is under active development and APIs may change between minor versions, but we use it in production at Documenso and consider it ready for real-world use. LibPDF was born from frustration. At Documenso, we found ourselves wrestling with the JavaScript PDF ecosystem: PDF.js is ex
Standard JSON Schema
A standardized JSON Schema representation that preserves inferred type information Standard JSON Schema is a common interface designed to be implemented by JavaScript and TypeScript entities that are or can be converted to JSON Schema. The goal is to make it easier for ecosystem tools to accept user-defined types (typically defined using schema/validation libraries) without needing to write custom
JavaScript/TypeScript実力強化書 | 技術評論社
概要 一気にJavaScript・TypeScriptのエキスパートへ！ Software Design本誌再編集シリーズ、今度はWeb開発者の必修科目であるJavaScriptとTypeScriptがテーマです。第一線のエンジニアが現場で培った、JavaScript・TypeScriptを最大活用する秘訣を伝授します。 第1章ではJavaScriptの歴史をさかのぼりつつ、基本的な仕様やコーディング作法を解説します。第2章でJavaScriptの関数について、関数のしくみ、引数、関数型プログラミングなどの観点で徹底的に解き明かします。第3章では、JavaScriptの非同期処理について、非同期処理そのものの変遷から、並行・並列処理の違い、Promiseやasync/await、AbortSignal/AsyncLocalStorageまで詳細に掘り下げます。第4章では、TypeScrip
minify の効果を最大限に引き出す TypeScript コードを書く
はじめに 2024年の11月に、札幌で開催された「クラメソさっぽろIT勉強会(仮) #6」という勉強会がありまして、そのライトニングトーク枠に登壇してきました。 タイトルは「minifyの効果を最大限に引き出すTypeScriptコードを書く」です。 昨今のフロントエンド開発では、TypeScriptを使ってコーディングし、それをトランスパイルしてできたJavaScriptファイルのサイズを minify によって削減するのが一般的でしょう。そうしたときに、ふと 「TypeScript の書き方を工夫したら、もっと minify が効率的に効くようになるかも?」 と思いたち、型安全性とコードの読みやすさを壊さない範囲で、どこまでファイルサイズを削れるか挑戦してみた、という話です。 今回はその LT ネタを、改めてブログ記事として共有させて頂きます。 今回のお題: Blazor SplitC
