CodeSense turns Baseline documentation into a tool that keeps your web app future-proof.


The Problem

Ever found yourself asking: "Can I actually use this cool new web feature in my project?"

If you're a web developer, you know the drill. You end up juggling a dozen tabs—MDN, CanIUse, blog posts, compatibility tables—just to figure out if a feature is safe to use. It's a mess.

This broken workflow leads to:

  • Over-polyfilling: Bloating your app with unnecessary code, "just in case."
  • Under-polyfilling: Shipping code that breaks on older browsers, leading to angry users.
  • Lost Productivity: Wasting precious time on manual research instead of building.

This uncertainty is a tax on every web developer's productivity.

Our Solution

CodeSense is here to fix that. It's a developer tool powered by Baseline that makes web feature compatibility an automated part of your workflow.

Here’s what it does:

  • Scans your code to see which modern web features you're using.
  • Checks their Baseline compatibility status using official, up-to-date data.
  • Helps you decide if a polyfill is needed, and can even inject it for you.
  • Warns you early—right in your IDE, linter, or CI/CD pipeline.
  • Generates reports and AI-powered suggestions to help you write future-proof code.

In short, CodeSense makes Baseline data actionable inside your workflow.

✨ Key Features

MVP (Ready to Go)

  • 💻 Code Scanner (CLI): A command-line tool that scans your project, detects the web APIs you're using, and flags any that aren't Baseline-compatible.
  • 📊 Baseline Check: Uses the official web-features npm package and the Web Platform Dashboard API to give you a clear status for each feature:
    • ✅ Safe: Widely supported.
    • ⚠️ Partial: Newly available and might need checking.
    • ❌ Not Baseline: Risky, needs a polyfill.
  • 📄 Report Generator: Generates simple CLI output, as well as detailed Markdown and HTML reports showing your project's Baseline compliance percentage and any risky features.

Advanced (What's Coming Next)

  • ✍️ ESLint Plugin: Get inline warnings right in your code as you type.
  • 💉 Smart Polyfill Injection: Automatically add only the polyfills you need, right when you need them, using Babel.
  • 🚀 CI/CD Integration: A GitHub Action that can block deployments if unsafe features are found, acting as a guardrail for your production builds.
  • 🤖 AI Suggestions: Recommends Baseline-safe alternatives for any risky features you're using.
  • 📈 Dashboard UI: A visual dashboard with charts and graphs to show your project's compliance over time.

🚀 Getting Started

Note: This project is currently under development. The CLI tool is not yet published to npm.

To run the CodeSense CLI locally, follow these steps:

  1. Clone the repository:

    git clone https://github.com/Recursion-Labs/codesense.git
    cd codesense
    
  2. Install dependencies:

    npm install
    
  3. Build the CLI:

    npm run build:cli
    

    (Note: The build is currently facing some issues. We're working on fixing them!)

  4. Run the CLI:

    node dist/cli.js
    

VS Code Extension

A VS Code extension is also planned! You'll be able to install it from the marketplace and get real-time feedback in your editor.

🌟 Why CodeSense? (Our Vision)

We believe that building for the web should be easier. Our vision is to create a tool that is:

  • Baseline Native: The first tool of its kind to directly integrate with the official Baseline data sources.
  • End-to-End: Covering your entire workflow, from writing code in your IDE to building and deploying with CI/CD.
  • Smart: Reducing your bundle size by avoiding unnecessary polyfills and giving you intelligent suggestions.
  • Future-Proof: Helping you understand when features will become part of Baseline, so you can plan for the future.
  • Team-Ready: With compliance badges, CI/CD guardrails, and shareable reports, it's built for teams of all sizes.

🏆 Hackathon Project
