Create Backend Service

Use this skill to follow the route (controller) + service split used in server/src/.

Steps

1. Create the service module

• Location: server/src/services/{serviceName}.js
• Use template_service.js from this folder.
• Prefer small exported functions (keep them easy to test).

2. Create the route module

• Location: server/src/routes/{routeName}.js
• Use template_route.js from this folder.
• Validate inputs near the route (or use server/src/contracts/httpSchemas.js when applicable).

3. Mount the route

• Register it in server/src/index.js:
  • app.use('/api/your-scope', yourRouter);

Naming notes

• Prefer existing naming patterns:
  • Routes: dataRoutes.js, runRoutes.js, indicatorExecutionRoutes.js
  • Services: marketWindowService.js, leanService.js, runStore.js
