TypeScript IntelliSense for Web

TypeScript + Vue + Astro Support on Web IDE based on Volar.js

Why?

• VSCode's built-in TypeScript extension does not support across files type-check and IntelliSense on Web IDE (github.dev), this extension implements that.

• Since the node_modules cannot be installed by opening the project through github.dev, type hints is almost completely lost. This extension will download the missing node_modules .d.ts file from CDN, and the experience is theoretically consistent with TypeScript Playground.

Try it:

• https://github.dev/johnsoncodehk/volar-starter
• https://vscode.dev/github/johnsoncodehk/volar-starter

Syntax Highlighting and Grammar

This extension only includes IntelliSense support; you will still need to install the corresponding extensions for syntax highlighting and grammar:

• Vue: https://marketplace.visualstudio.com/items?itemName=Vue.volar
• Astro: https://marketplace.visualstudio.com/items?itemName=astro-build.astro-vscode

Disable Built-in TypeScript Extension

This extension and the Built-in TypeScript Extension sometimes show duplicate results, which is not a big problem, but you still can disable the Built-in TypeScript Extension yourself if you want, please refer to https://vuejs.org/guide/typescript/overview.html#volar-takeover-mode.
