"What the heck type am I actually supposed to put here?". </p> <p>To save time and keep your momentum, you slap an <code>any</code> type on it and promise yourself you'll "fix it later." (Spoiler alert: we rarely do).</p> <p>Manually tracking down missing implicit <code>any</code> definitions or unannotated parameters can ruin your development flow. While paid AI extensions exist, they can be costly and frequently spam your terminal console with unreadable, messy raw string blocks.</p> <p>To solve this, I built <strong>typecraft-cli</strong> ⚡ — an entirely open-source, minimal static analysis tool that scans your codebase and leverages free Hugging Face LLMs to generate accurate TypeScript annotations automatically.</p> <p>Instead of cluttering your local environment, it streams suggestions straight into a neatly formatted <code>type-checker.md</code> file right in your workspace directory so you can reference it side-by-side with your code editor.</p> <h2> 🚀 Key Features </h2> <ul> <li> <strong>Automated Type Detection:</strong> Scans local directories to catch loose parameters and missing strict types.</li> <li> <strong>Open Source &amp; Free AI:</strong> Leverages specialized, open-source code models via Hugging Face. No OpenAI API keys required.</li> <li> <strong>Zero Terminal Clutter:</strong> Keeps your workspace completely quiet while processing everything into clean Markdown reports.</li> </ul> <h2> 🛠️ Quick Start </h2> <p>You can run it instantly using <code>npx</code>:</p> <p><code>npx typecraft-cli</code></p> <p>(Or install it globally via <code>npm install -g typecraft-cli</code>)</p> <h2> Prerequisties </h2> <p>Before running the tool, you'll need a Hugging Face Inference API token (it's free!) so the CLI can communicate with the open-source LLMs:</p> <ul> <li>1. - Grab your token from your Hugging Face Settings.</li> <li>2. - Create a .env file in the root of your project.</li> <li>3. - Add your token like this: Code snippet <code>HF_TOKEN=your_actual_token</code> </li> </ul> typescript opensource ai npm
