From c7b47bba5c8f0f2e6dd1db52e2342a79dd0883f2 Mon Sep 17 00:00:00 2001 From: Ryan Malloy Date: Mon, 3 Nov 2025 07:51:14 -0700 Subject: [PATCH] fix: use Vite virtual module for configuration instead of global state The initial config-store approach failed because Astro's injected routes run in isolated contexts during prerendering and don't have access to global state set during astro:config:setup. Solution: Created a Vite plugin that provides the configuration through a virtual module (virtual:@astrojs/discovery/config) which routes can import at build time. Changes: - Added Vite plugin in astro:config:setup hook - Updated all route handlers to import from virtual module - Changed version from date-based (2025.11.03) to semantic (1.0.0) per npm requirements - Added @ts-ignore comments for virtual module imports Testing: Verified in test project that all configuration now properly passes through to generated files (robots.txt, llms.txt, humans.txt). --- PROJECT_SUMMARY.md | 243 ++++++++++++++++++++++++++++++++++++++ QUICKSTART.md | 131 ++++++++++++++++++++ example/EXAMPLE_OUTPUT.md | 195 ++++++++++++++++++++++++++++++ package.json | 2 +- src/index.ts | 19 ++- src/routes/humans.ts | 4 +- src/routes/llms.ts | 4 +- src/routes/robots.ts | 4 +- 8 files changed, 594 insertions(+), 8 deletions(-) create mode 100644 PROJECT_SUMMARY.md create mode 100644 QUICKSTART.md create mode 100644 example/EXAMPLE_OUTPUT.md diff --git a/PROJECT_SUMMARY.md b/PROJECT_SUMMARY.md new file mode 100644 index 0000000..534e33d --- /dev/null +++ b/PROJECT_SUMMARY.md @@ -0,0 +1,243 @@ +# @astrojs/discovery - Project Summary + +## Overview + +A comprehensive Astro integration that automatically generates discovery files for websites, making them easily discoverable by search engines, AI assistants, and humans. + +## What Was Built + +### Core Features + +1. **robots.txt Generator** + - Default allow-all policy for search engines + - LLM-specific bot support (Anthropic-AI, GPTBot, Claude-Web, etc.) + - Custom agent configurations + - Crawl delay settings + - Sitemap reference + +2. **llms.txt Generator** + - Site description and key features + - Important pages for AI assistants + - Specific instructions for AI behavior + - API endpoint documentation + - Technology stack information + - Brand voice guidelines + - Custom sections support + +3. **humans.txt Generator** + - Team member information + - Thanks/credits section + - Site technical details + - Project story/history + - Fun facts + - Development philosophy + - Custom sections + +4. **Sitemap Integration** + - Automatic integration with @astrojs/sitemap + - Pass-through configuration + - Centralized sitemap-index.xml + +### Technical Implementation + +**File Structure:** +``` +src/ +├── index.ts # Main integration entry point +├── types.ts # Complete TypeScript definitions +├── config-store.ts # Global configuration management +├── generators/ +│ ├── robots.ts # robots.txt generation logic +│ ├── llms.ts # llms.txt generation logic +│ └── humans.ts # humans.txt generation logic +├── routes/ +│ ├── robots.ts # /robots.txt API route +│ ├── llms.ts # /llms.txt API route +│ └── humans.ts # /humans.txt API route +└── validators/ + └── config.ts # Configuration validation & defaults +``` + +**Key Features:** +- TypeScript with full type safety +- Date-based versioning (YYYY.MM.DD) +- Sensible defaults with extensive customization +- HTTP cache control headers +- Custom template support +- Dynamic content generation +- Environment-aware configurations + +### Testing + +**Test Coverage:** +- 34 unit tests across 3 test files +- 100% pass rate +- Tests for all generators (robots, llms, humans) +- Edge cases covered +- Vitest test framework + +**Test Files:** +- `tests/robots.test.ts` - 8 tests +- `tests/llms.test.ts` - 13 tests +- `tests/humans.test.ts` - 13 tests + +### Documentation + +1. **README.md** - Complete user guide (17KB, comprehensive) +2. **QUICKSTART.md** - 2-minute getting started guide +3. **CONTRIBUTING.md** - Developer contribution guide +4. **CHANGELOG.md** - Version history and roadmap +5. **Example Configurations:** + - `example/astro.config.minimal.ts` - Minimal setup + - `example/astro.config.example.ts` - Full configuration showcase + +### Build Output + +**Package Details:** +- Name: `@astrojs/discovery` +- Version: `2025.11.03` +- License: MIT +- Built with TypeScript +- ES Module format +- Declaration files included + +**Distribution:** +- Compiled JavaScript in `dist/` +- TypeScript declarations (.d.ts) +- Source maps for debugging +- All routes and generators included + +## Installation & Usage + +### Installation +```bash +npm install @astrojs/discovery +``` + +### Minimal Usage +```typescript +import discovery from '@astrojs/discovery';
