What Programming Language Is Archify Written In? Node.js and JavaScript Explained

Archify is implemented in JavaScript using ECMAScript modules and requires Node.js version 18 or higher to execute.

The open-source repository tt-a1i/archify is a rendering and validation system whose entire source base consists of JavaScript code built specifically for the Node.js runtime. Understanding what programming language Archify is written in helps developers contribute effectively and deploy the tool correctly across different environments.

JavaScript ES Modules and Node.js Runtime

According to the archify/package.json configuration, Archify declares "type": "module"【/cache/repos/github.com/tt-a1i/archify/main/archify/package.json#L5-L13】, confirming that the codebase uses modern ECMAScript modules rather than CommonJS. The same file specifies the engine requirement as "node": ">=18"【/cache/repos/github.com/tt-a1i/archify/main/archify/package.json#L5-L13】, establishing Node.js as the exclusive runtime environment.

The project's own documentation in README.md explicitly states that "Archify is a Node.js rendering and validation system..."【/cache/repos/github.com/tt-a1i/archify/main/README.md#L15-L16】, confirming the JavaScript runtime dependency at the architectural description level.

Entry Point and Core Implementation

The primary executable resides at archify/bin/archify.mjs, a JavaScript module that serves as the command-line interface entry point. This file imports native Node.js APIs including fs, path, and child_process【/cache/repos/github.com/tt-a1i/archify/main/archify/bin/archify.mjs#L1-L14】, demonstrating direct integration with the Node.js standard library for file system operations and process management.

The .mjs extension (ECMAScript Module JavaScript) reinforces the use of ES module syntax, allowing the use of import and export statements natively without transpilation.

CLI Usage and JavaScript Execution

Since Archify is a Node.js application distributed via npm, you interact with the JavaScript code through the Node runtime. The following commands demonstrate how the JavaScript entry point orchestrates rendering and validation workflows:

# Install Archify globally (downloads the JavaScript package)

npx skills add tt-a1i/archify -g

# Render an architecture diagram from JSON IR

archify render architecture my-diagram.json output.html

# Validate a diagram without producing output

archify validate architecture my-diagram.json --json

These commands invoke the archify.mjs script, which processes arguments using Node.js APIs and executes the rendering pipeline entirely within the JavaScript engine.

Key Source Files Confirming the Language Choice

File	Significance
archify/package.json	Declares "type": "module" and Node.js >=18 engine requirement
archify/bin/archify.mjs	Main CLI implementation written in JavaScript using ES modules
README.md	Explicitly describes Archify as a "Node.js rendering and validation system"

Summary

• Archify is written in JavaScript using ECMAScript modules (ESM) syntax as confirmed by the package.json configuration.
• The project requires Node.js version 18 or higher as specified in the engines field.
• The entry point archify/bin/archify.mjs uses native Node.js APIs including fs, path, and child_process.
• The codebase contains no compiled languages like TypeScript or C++ in the core runtime implementation.

Frequently Asked Questions

Is Archify written in TypeScript?

No, the source code analysis confirms Archify is written in vanilla JavaScript. The package.json sets "type": "module" for native ES modules, and the core implementation files use standard .mjs JavaScript extensions without TypeScript compilation artifacts.

What Node.js version does Archify require?

Archify requires Node.js 18 or higher, as declared in the engines field of archify/package.json【/cache/repos/github.com/tt-a1i/archify/main/archify/package.json#L5-L13】. This ensures compatibility with modern JavaScript features and stable ES module support.

Does Archify use CommonJS or ES modules?

Archify uses ES modules (ESM) exclusively. The package.json explicitly sets "type": "module", and the CLI entry point uses the .mjs extension, confirming ECMAScript module syntax throughout the codebase rather than CommonJS require syntax.

Can I run Archify without Node.js installed?

No, because Archify is fundamentally a Node.js application written in JavaScript. The executable archify.mjs relies on Node.js built-in modules like fs and child_process, making the Node.js runtime a mandatory dependency for any execution.
