vue-property-decorator VS TypeScript

In my last project these two were used a lot: https://github.com/kaorun343/vue-property-decorator and https://class-component.vuejs.org/

Designed for vue 3, do the same work like vue-class-component and vue-property-decorator.

When I was using Vue2 along with vue-class-component and vue-property-decorator it was easy to synchronize v-models between components simply using @ModelSync(). When Vue 3 came out with its Composition API another way was needed to achieve the same result as if Class Component was used.

This is still not better than Vue Class Component & Vue Property Decorator . Very easy syntax, looks like any other OOP language, and looks so much cleaner.

vue-property-decorator: This library works hand in hand with vue-class-component so that you can define properties/methods on your class for things like watchers, properties, etc:

The next thing to tackle for a scalable application is, that we want to have a well written component that is easy to read and to reuse. Vue components are usually single file, which has it's benefits (e.g. if you want to change some css, and then html and oh, you also need to introduce this property in typescript...). It's also easier to maintain some code standard about how large a component should possibly become, if you had single file components (e.g. >250loc => linter error). To additionally increase readability, I like to use typescript class components flavoured with vue property decorators.

Here, we will cover only the basics, the idea is in the future to create an article on Vue-Property-Decorator that complements the usage of this library.

Vue2 não é muito bom pra lidar com typescript de forma vanilla, então o próprio core team e a comunidade criaram soluções pra você ter sintaxes alternativas (nada muito diferente) que suportam os toolings mais modernos e que tiveram maior adoção no decorrer dos últimos anos, como o vue-class-component, vue-property-decorator e o vuex-class. O caso mais notório de ferramenta que tira proveito disso, com certeza é o typescript. Com essas tecnologias, usar typescript é 100% possível, e usando essas sintaxes alternativas, diria até que o código fica mais enxuto e claro do que o vue sem nada (@Action do vuex-class, pra mim, tem uma sintaxe mais agradável que mapActions do vuex cru, por exemplo). Começamos o projeto sem, mas o Brunão começou a implementar usando isso e com uma curva bem pequena de aprendizado, aderimos felizes ao novo método de escrever componentes vue2.

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.
