Features

• Simple UI for takeoff-performance pages (linked from index.html)
• Node/Express static server for local hosting
• Minimal test that validates an aircraft JSON file

Quick start

Prerequisites

• Node.js (v16+ recommended)
• npm

Install dependencies

npm install

Run locally

npm start
# Server starts at http://localhost:3000

Run tests

npm test
# Runs test.js which validates data/Cessna 152.json

Available scripts

• start — runs node server.js and starts the web server (default port: 3000)
• test — runs node test.js to validate aircraft JSON in data/

Project layout

• index.html — main landing page (links to pages/takeoff.html)
• pages/ — directory intended for individual pages (e.g., takeoff.html)
• data/ — aircraft JSON files (test expects data/Cessna 152.json)
• server.js — Node/Express server:
  • serves static files from a public directory (see note below)
  • provides a health endpoint at /api/health
• test.js — simple Node test that loads data/Cessna 152.json and asserts fields
• package.json / package-lock.json — package metadata and dependencies (express)
• .github/ — present but not detailed here
• index.html.css and index.html.js — present as files but currently empty

Usage

• Open http://localhost:3000 after npm start. The server logs:

  Server running at http://localhost:3000
  

• The landing page (index.html) links to pages/takeoff.html for the takeoff-performance calculator.
• The tests are standalone and read JSON files from the data/ folder, so make sure the expected JSON files exist before running npm test.

Notes & TODOs

• server.js serves static files from a public directory:

  app.use(express.static(path.join(__dirname, "public")));

  But index.html and pages/ are currently in the repository root. You should either:
  • Move index.html, pages/, and other static assets into a public/ directory, or
  • Change server.js to serve the repository root (or the directory where those files live). Example change:

    // serve files from repo root:
    app.use(express.static(path.join(__dirname)));

• test.js expects data/Cessna 152.json. If that file is missing, tests will fail. Make sure your aircraft JSON files are in data/.
• index.html.css and index.html.js are empty placeholder files — populate or remove them as needed.
• package.json "name" is currently "takeoff-performance" which differs from the repository name; consider aligning naming if desired.
• Consider adding a public/ directory, or reorganizing static assets for clearer structure.
• Add a LICENSE file if you want to declare the project license.
