Back to business: fortunately, Postman has built-in full support for GraphQL! 🎉Let's take a quick tour of the capabilities by exploring the Rick and Morty API. To get started, create a new HTTP request in Postman. Set the request mode to POST and the URL to https://rickandmortyapi.com/graphql. Now; in the body section, select GraphQL. You should end up with something like this:

import "@/styles/globals.css"; import type { AppProps } from "next/app"; import { ApolloClient, InMemoryCache, ApolloProvider } from "@apollo/client"; const client = new ApolloClient({ uri: "https://rickandmortyapi.com/graphql", cache: new InMemoryCache(), }); export default function App({ Component, pageProps }: AppProps) { return ( ApolloProvider> ); }

import React from 'react'; import ReactDOM from 'react-dom/client'; import './index.css'; import App from './App'; import { ApolloClient, ApolloProvider, InMemoryCache } from '@apollo/client' const client = new ApolloClient({ uri: "https://rickandmortyapi.com/graphql", cache: new InMemoryCache(), }) const root = ReactDOM.createRoot(document.getElementById('root')); root.render( );

I have a next.js app that uses dynamic routes. Here is the repo on Github https://github.com/ChristianOConnor/graphql-next-api-tester. Run the app by cloning the repo and cd-ing into the root directory, running npm install then npm run dev. It works perfectly. It's a next.js app that does graphql calls to https://rickandmortyapi.com/graphql, and renders them out into a table. You first click on the "List of characters" button in the middle of the home page: [![enter image description here][1]][1]

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.
