commit a7bd6115b799dced7bb62ebd99b7d0022588f86a Author: Alexis Trouvé Date: Mon Sep 15 23:06:10 2025 +0800 feat: Implémentation complète du système SourceFinder avec tests - Architecture modulaire avec injection de dépendances - Système de scoring intelligent multi-facteurs (spécificité, fraîcheur, qualité, réutilisation) - Moteur anti-injection 4 couches (preprocessing, patterns, sémantique, pénalités) - API REST complète avec validation et rate limiting - Repository JSON avec index mémoire et backup automatique - Provider LLM modulaire pour génération de contenu - Suite de tests complète (Jest) : * Tests unitaires pour sécurité et scoring * Tests d'intégration API end-to-end * Tests de sécurité avec simulation d'attaques * Tests de performance et charge - Pipeline CI/CD avec GitHub Actions - Logging structuré et monitoring - Configuration ESLint et environnement de test 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude diff --git a/.eslintrc.js b/.eslintrc.js new file mode 100644 index 0000000..87ae34d --- /dev/null +++ b/.eslintrc.js @@ -0,0 +1,36 @@ +module.exports = { + env: { + browser: false, + commonjs: true, + es2021: true, + node: true, + jest: true + }, + extends: [ + 'eslint:recommended' + ], + parserOptions: { + ecmaVersion: 12, + sourceType: 'module' + }, + rules: { + 'indent': ['error', 2], + 'linebreak-style': ['error', 'unix'], + 'quotes': ['error', 'single'], + 'semi': ['error', 'always'], + 'no-unused-vars': ['warn'], + 'no-console': 'off', + 'no-undef': 'error' + }, + globals: { + 'describe': 'readonly', + 'test': 'readonly', + 'it': 'readonly', + 'expect': 'readonly', + 'beforeAll': 'readonly', + 'afterAll': 'readonly', + 'beforeEach': 'readonly', + 'afterEach': 'readonly', + 'jest': 'readonly' + } +}; \ No newline at end of file diff --git a/.github/workflows/ci.yml b/.github/workflows/ci.yml new file mode 100644 index 0000000..3ef08b5 --- /dev/null +++ b/.github/workflows/ci.yml @@ -0,0 +1,363 @@ +name: SourceFinder CI/CD Pipeline + +on: + push: + branches: [ main, develop ] + pull_request: + branches: [ main, develop ] + +env: + NODE_VERSION: '18.x' + NODE_ENV: test + +jobs: + # Étape 1: Linting et validation du code + lint: + name: Code Quality & Linting + runs-on: ubuntu-latest + steps: + -
