NX Language

Language support for NX: a modern language for executable markup, built for dynamic, AI-native experiences. Open any .nx file to get highlighting, diagnostics as you type, hover information and completions.

type Task = { title:string  done:boolean = false }

let <TaskList tasks:Task+ /> =
  <ul>
    for task in tasks {
      <li checked={task.done}>{task.title}</li>
    }
  </ul>

New to NX? Start with Getting Started or try it without installing anything in the playground.

Features

• Syntax highlighting for .nx files, and for ```nx code blocks in Markdown.
• Diagnostics from the NX language server: syntax and type errors appear as you type.
• Hover shows the declaration and type of what is under the cursor.
• Completions for keywords, types, declarations, components, their properties and union cases.
• Outline: types, functions, components and values show up in the Outline view and in Go to Symbol in Editor.
• Snippets (type nx to list them) for elements, unions, if, for, match and braced values.
• Comment toggling, bracket matching and auto-closing pairs.

The language server ships inside the extension, so there is nothing else to install. It is packaged for Windows (x64), macOS (Apple silicon) and Linux (x64).
