Error Handling Patterns
Very timely, was just trying to understand how to improve error handling with typescript recently and came across neverthrow (https://github.com/supermacro/neverthrow) which looks promising…

Ask HN: What is the “proper” way to do error-handling in TypeScript?
On my team we use Rust-style Result/Option types for any unrecoverable exceptions.

The gotcha of unhandled promise rejections
I was happy when Promise became available, but in retrospect I'd wish we would have skipped ahead and gotten Observable (e.g: https://rxjs.dev/) instead to enable more powerful functionality and composition etc.
In Typescript dealing with rejection is also painful since rejection reasons can't be guaranteed to be Error even when you always take care of that. And it can't help you guarantee that you're handling all types of errors thrown. For that purpose I'm thinking of using https://github.com/supermacro/neverthrow#readme or https://swan-io.github.io/boxed.

How has learning Rust been a benefit to you in other programming areas?
I highly recommend the neverthrow library for bringing Result to Typescript.

functional error handling (functions return error) recommendations
I like the Result monad from here: https://github.com/supermacro/neverthrow

How to know if a function throws in Typescript?
What do you think of neverthrow?

ts-results - a lightweight result wrapper to exhibit success/failure instead of using/throwing exceptions.
I use https://github.com/supermacro/neverthrow for this

Handle Javascript errors like in Go
See neverthrow as an example of correctly encoding the failure into the return type of the function.
- Why doesn't typescript have a throws type to annotate functions that can throw an error?
-
what's the recommended way to handle error in TS?
I use Neverthrow. Same idea, concurrent projects...

JSR Is Not Another Package Manager
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.

TypeScript Essentials: Distinguishing Types with Branding
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.

Smart Contract Programming Languages: sCrypt vs. Solidity
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.

Understanding the Difference Between Type and Interface in TypeScript
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.

Type-Safe Fetch with Next.js, Strapi, and OpenAPI
TypeScript helps you in many ways in the context of a JavaScript app. It makes it easier to consume interfaces of any type.

How to scrape Amazon products
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.
