TPMJS

TPMJS is a registry for discovering AI tools published to npm.

Browse, search, and find tools at tpmjs.com. Publish your tool by adding the tpmjs-tool keyword to your package.json—it appears in the registry within 15 minutes.

Why TPMJS?

• Discover tools - Search and browse AI tools by category, quality score, and popularity
• Publish easily - Add one keyword to package.json, publish to npm, done
• Quality metrics - Tools are scored based on documentation, downloads, and metadata completeness
• Agent integration - Optional SDK for agents to search and execute tools at runtime

Quick Start

Publishing a Tool

npx @tpmjs/create-basic-tools

Or add manually to your package.json:

{
  "keywords": ["tpmjs-tool"],
  "tpmjs": {
    "category": "text-analysis"
  }
}

Publish to npm and your tool appears on tpmjs.com within 15 minutes.

See HOW_TO_PUBLISH_A_TOOL.md for the full guide.

For AI Agents (Optional)

Agents can search and execute tools from the registry:

npm install @tpmjs/registry-search @tpmjs/registry-execute

import { registrySearchTool } from '@tpmjs/registry-search';
import { registryExecuteTool } from '@tpmjs/registry-execute';

// Add to your agent's tools
const tools = [registrySearchTool, registryExecuteTool];

Getting Started

Prerequisites

• Node.js >= 22 (LTS)
• pnpm >= 8
• nvm (recommended for Node version management)

Installation

pnpm install

Development

# Run all apps in development mode
pnpm dev

# Run specific app
pnpm --filter @tpmjs/web dev
pnpm --filter @tpmjs/storybook dev

Building

# Build all packages and apps
pnpm build

# Build specific package
pnpm --filter @tpmjs/ui build

Testing

# Run all tests
pnpm test

# Run tests in watch mode with UI
pnpm test:ui

Linting & Formatting

# Lint all packages
pnpm lint

# Format all files
pnpm format

# Check formatting
pnpm format:check

Quality Gates

# Check architecture/dependency rules
pnpm check-architecture

# Find unused code and dependencies
pnpm find-deadcode

# Check type coverage
pnpm type-coverage

See QUALITY-GATES.md for details.

Component Usage

Components are imported directly without barrel exports:

import { Button } from '@tpmjs/ui/Button/Button';
import { Card, CardHeader } from '@tpmjs/ui/Card/Card';

Important: All UI components use .ts extension (not .tsx) and use createElement instead of JSX.

Publishing Workflow

1. Create Changesets

After making changes to publishable packages:

pnpm changeset

Follow the prompts to describe your changes and select which packages are affected.

2. Version Packages

When ready to release:

pnpm changeset:version

This updates package versions and generates CHANGELOGs.

3. Publish to npm

pnpm changeset:publish

This builds and publishes all packages with changesets to npm.

4. Push to GitHub

git push --follow-tags

Published Packages

• @tpmjs/ui - React component library
• @tpmjs/utils - Utility functions
• @tpmjs/types - TypeScript types
• @tpmjs/env - Environment schema loader

Deployment

The project is configured to only deploy to Vercel when all CI checks pass. This ensures production always has high-quality, tested code.

CI Checks:

• Linting & formatting
• Type checking
• Tests
• Production build
• Architecture validation
• Dead code detection

See DEPLOYMENT.md for full configuration details.

Module Boundaries

ESLint enforces module boundaries:

• Apps can import from published packages only
• Packages cannot import from apps
• No barrel exports (index.ts) allowed
• Direct imports required: @tpmjs/ui/Button/Button

Architecture Decisions

Why .ts-only Components?

Using .ts instead of .tsx for React components:

• Enforces explicit createElement calls
• Makes React's runtime nature more visible
• Prevents JSX spreading anti-patterns
• Better for code generation and tooling

Why No Barrel Exports?

• Clearer dependency graphs
• Better tree-shaking
• Explicit imports show what's actually used
• Prevents circular dependencies

Why Biome + ESLint?

• Biome: Fast formatting and basic linting
• ESLint: Semantic rules (module boundaries, TypeScript strictness)
• Each tool focuses on what it does best

Scripts Reference

• check-architecture - Validate dependency rules
• find-deadcode - Find unused code/dependencies
• clean - Remove build artifacts
• changeset - Create a changeset
• changeset:version - Version packages
• changeset:publish - Publish to npm
