TypeScript VS esbuild

While we were fighting against the modules, we forgot one small detail - their built-in typings. Esbuild can't do this at all yet. Unbelievable, but the tsc, native TS compiler, also does not provide a typings concat feature. Got around this problem: we've introduced [a utility to combine typings](tsc-dts-fix of zx own code, and applied some monkey patches for external libdefs squashed via dts-bundle-generator.

Regular expressions are part of the language, so it's not so unreasonable that TypeScript should parse them and take their semantics into account. Indeed, TypeScript 5.5 will include [new support for syntax checking of regular expressions](https://github.com/microsoft/TypeScript/pull/55600), and presumably they'll eventually be able to solve the problem the GP highlighted on top of those foundations.

Dedicated syntax for creating unique subsets of a type that denote a particular refinement is a longstanding ask[2] - and very useful, we've experimented with implementations.[3]

I don't think it has any relation to runtime type checking at all. It's refinement types, [4] or newtypes[5] depending on the details and how you shape it.

Learning Curve and Developer Tooling sCrypt is an embedded Domain Specific Language (eDSL) based on TypeScript. It is strictly a subset of TypeScript, so all sCrypt code is valid TypeScript. TypeScript is chosen as the host language because it provides an easy, familiar language (JavaScript), but with type safety. There’s an abundance of learning materials available for TypeScript and thus sCrypt, including online tutorials, courses, documentation, and community support. This makes it relatively easy for beginners to start learning. It also has a vast ecosystem with numerous libraries and frameworks (e.g., React, Angular, Vue) that can simplify development and integration with Web2 applications.

As a JavaScript or TypeScript developer, you might have come across the terms type and interface when working with complex data structures or defining custom types. While both serve similar purposes, they have distinct characteristics that influence when to use them. In this blog post, we'll delve into the differences between types and interfaces in TypeScript, providing examples to aid your understanding.

TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.

In this guide, we'll be extracting information from Amazon product pages using the power of TypeScript in combination with the Cheerio and Crawlee libraries. We'll explore how to retrieve and extract detailed product data such as titles, prices, image URLs, and more from Amazon's vast marketplace. We'll also discuss handling potential blocking issues that may arise during the scraping process.

At first we wanted to just get rid of all the helper utilities. Keep only the kernel, but this would mean a loss of backward compatibility. We needed some efficient code processing instead with recomposition and tree-shaking. We needed a bundler. But which one? Our testing approach relies on targets, not sources. We rebuilt the project frequently, speed was critical requirement. In essence, we chose a solution from a couple of among all available alternatives: esbuild and parcel. Esbuild won. Specifically in our case, it proved to be more productive and customizable.

During my search for deploying Lambdas via GitHub actions, I came across a tutorial that utilized ncc for converting TypeScript and bundling. While ncc is effective, I discovered esbuild, which proved to be significantly faster and perfectly suited to my requirements.

The advent of esbuild, the native support for ES Modules in browsers, the widespread adoption of import map, the emergence of tools like Native Federation, and the Nx ecosystem all combine to forge a flexible and well-maintained Micro Frontend Architecture.

EsBuild is a relatively new, blazing-fast JavaScript bundler and minifier. It stands out for its high performance, significantly speeding up the build process in development pipelines.

Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

Use esbuild to build the React code into a form executable on both the server and client sides.

The functions will bundle using esbuild. For that, it is required to install esbuild globally:

TSX is the newest and most improved version of our ts-node, using ESBuild to transpile TS files to JS very quickly. The most interesting part is that TSX was developed to be a complete replacement for Node, so you can actually use TSX as a TypeScript REPL, if you install it globally with npm i -g tsx, just run tsx in your terminal and you can write TSX natively. But what's even cooler is that you can load TSX for all TypeScript files using --loader tsx when you run your file. For example, let's say we have this file called index.ts:

esbuild plus Vite is out of developer preview and enabled by default, yielding 67%, 87%, 80% speed improvements for build time, hybrid build time and hybrid serve time respectively.
