What technology is Tree (tree.nathanfriend.com) built with?

Updated

Tree (tree.nathanfriend.com) is built with TypeScript and React. It is an online, browser-based utility for generating ASCII folder structure diagrams, and its own source description states it was "written in TypeScript and React." Because it runs as a web app in the browser, it requires JavaScript to be enabled — the page itself only shows "You need to enable JavaScript to run this app." when scripts are blocked.

What the stack means in practice

Aspect Detail What it means for you
Language TypeScript Typed JavaScript source; the app is compiled to run in the browser
UI framework React Component-based interface rendered client-side
Delivery Online web app You use it through a browser at tree.nathanfriend.com
Runtime requirement JavaScript enabled With JS disabled, the app does not load or run
Processing model Client-side utility Diagram generation happens in the browser rather than on a server

Why this matters for using Tree

  • No install step is described. The tool is presented as an online utility, so the intended entry point is the website itself rather than a local package.
  • JavaScript is a hard prerequisite. If you see only the "enable JavaScript" message, the React app has not started, and no diagram features will be available until scripts are allowed.
  • The output is text-based. Tree is described as generating ASCII folder structure diagrams, so the result is plain-text tree notation you can copy into documentation, README files, or notes.
  • TypeScript and React are implementation details, not user requirements. You do not need to know either technology to use the tool; they describe how the app was authored.

What is not specified

The available source material does not state a license, hosting provider, build tooling, pricing, or whether the project is open source. Those details should be checked directly on the site or its repository if they matter to your decision.
