esnext | 介绍最新的 ECMAScript/JavaScript 规范，以及 TC39 的提案进度 | Script Programming library

I have a project with E2E tests setup with Playwright + TS-Jest. To organize my tests I use Page Object Model. Structure looks like that:

I wanted to use TypeScript paths option in tsconfig.json to clean up the imports both in test files as well as in POM classes. After some trial and error I came up with the following config files:

Im using Typescript, Electron, Webpack and NodeJS to make a webapp but for some reason the import/export isnt working properly.

The error im receiving is:

"Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports."

Ive tripled checked my imports and exports and the component is still undefined when its called.

Console.Log Output of appView.tsx imported component:

I'm quiete desperate at the moment. I tried to build my first custom block for Gutenberg editor according to these tutorials:

• https://awhitepixel.com/blog/wordpress-gutenberg-create-custom-block-tutorial/
• https://developer.wordpress.org/block-editor/how-to-guides/javascript/js-build-setup/ and https://developer.wordpress.org/block-editor/how-to-guides/block-tutorial/writing-your-first-block-type/

I followed exactly the tutorials, but I can't even see the first example block in the Gutenberg editor. In the browser console occurs the error

I have two global types files emotion.d.ts and global.d.ts, and they're no longer being picked up.

Currently using emotion theme and created a global types file for in emotion.d.ts that looks something like this:

[UPDATE]

This issue was originally solved by uninstalling tsc with npm uninstall tsc (as suggested by the marked answer). However, the issue came back and after a long time had passed I tried using Windows Server for Linux (WSL) with VSCode. It did the trick immediately, so that is the solution I've stuck with.

I am having an issue running the tsc command using an NPM script:

I have a react app in typescript that cant compile for unknown reasons. This is the error I get:

I'm having problems creating my angular project, I've already tried updating @angular / core tried to delete a node modules folder and install again I changed the version of my node and npm Nothing works

This is my tsconfig.json

I am using .Net Core 3.1 with React, Typescript and webpack for an SPA. I have multiple modules in react which I load on different page/view of Asp.Net core application.

I am facing issue with auto refresh or hot reload. When I change a parameter which I am passing from module to a component hot reload works as expected BUT if I do any change in component then those are not getting reflected in browser.

If I browse https://localhost:5010/webpack-dev-server I can see home.bundle.js there. Also if change value of "msg" param/prop of HomeComponent in HomeModule.tsx, I can see new bundle generated for home.bundle.js with fresh hashcode and change also reflects to browser on https://localhost:5010/home/ BUT If I do change to HomeComponent.tsx ex: if I change "Home component" to "Home component 123" this change not getting reflected neither on https://localhost:5010/home nor the new bundle NOT generating on https://localhost:5010/webpack-dev-server.

Here is my project structure and files including configuration files. Any help will be highly appreciated.

Update: I added HotModuleReplacementPlugin to webpack.dev.config.js and now when I modify something in component HomeComponent.tsx I see a new entry in https://localhost:5010/webpack-dev-server something like "5f80de77a97d48407bd9.hot-update.json". If I open this file it's content is like {"h":"0dce1f9e44bff4d47fb4","c":{}}

Apart from this another issue is when I run application with F5 from Visual Studio it takes couple of seconds to load website until than browser shows "This site can't be reached"
