feat: Modernize Node.js environment, dependencies, and Docker setup

[romainPrignon]

This commit brings several foundational improvements to the project:

1. Node.js Modernization:

   • Updated Node.js engine to ^18.17.0 in package.json.
   • Updated npm engine to ^9.6.7 in package.json.
   • Updated @types/node to ^18.17.0.

2. Core Dependency Updates:

   • Upgraded TypeScript to ^5.2.2.
   • Upgraded ESLint to ^8.50.0 and its TypeScript plugins (@typescript-eslint/eslint-plugin, @typescript-eslint/parser) to ^6.7.3.
   • Added plugin:@typescript-eslint/recommended to ESLint configuration.
   • Upgraded Jest to ^29.7.0, ts-jest to ^29.1.1, and @types/jest to ^29.5.5.
   • Pinned Husky to ^8.0.0.

3. Dockerfile Enhancements:

   • Base images updated to node:18-alpine.
   • Corrected npm install commands to npm install --legacy-peer-deps (for build stage) and npm ci --only=production --legacy-peer-deps (for final stage).
   • Ensured package-lock.json is copied and used for installations.
   • Set the CMD to ["node", "dist/index.js"] to correctly run the application.

4. Build Process Improvements:

   • Added a .dockerignore file to optimize Docker build context.
   • Updated tsconfig.json for es2022 target and lib.
   • Updated .eslintrc.js for ecmaVersion: 2022.

These changes provide a more secure, stable, and modern foundation for future development.

package.json:51

• The jest-config version remains at 23.6.0 while Jest itself is updated to ^29.7.0, which may cause version mismatches or unexpected behavior. Consider updating jest-config to a compatible version or removing it if it’s no longer needed.

"jest-config": "23.6.0",

.dockerignore:6

• [nitpick] Ignoring the Dockerfile in .dockerignore can prevent it from being sent to the build context. It's generally recommended to keep the Dockerfile outside of ignore rules so builds remain reproducible.

Dockerfile

[Copilot]

[nitpick] Husky is configured under optionalDependencies, but it’s a development tool and should typically be in devDependencies to avoid shipping unnecessary packages to production.

Suggested change

	"typescript": "^5.2.2"
	},
	"optionalDependencies": {
	"typescript": "^5.2.2",

In the final stage you copy package-lock.json from the build context instead of the build stage. You may want to COPY --from=build /opt/package-lock.json . to ensure the exact lockfile used during build is applied in the runtime image.

Suggested change

	COPY package-lock.json .
	COPY --from=build /opt/package-lock.json .
