Build a RESTful API using Node.js with Express routing, PostgreSQL data modeling via Sequelize, and JWT-based authentication. This approach handles plan management, job workflows, schedule coordination, and contract tracking with OpenAPI documentation for API visibility.

Yes. Express provides routing and controllers while Sequelize manages PostgreSQL data models for construction entities like plans, jobs, and subdivisions. Combined with JWT RBAC authentication and Redis caching, they form a complete backend stack for construction APIs.

Implement input validation in controllers and enforce business rules in service layers, ensuring data integrity across plan creation, PDSS integration, and schedule coordination. This separation maintains clean routing while keeping complex construction logic centralized and testable.

Redis caching optimizes repeated queries on construction data, reducing database load for job lookups, schedule reads, and subdivision data. It's optional but recommended for scale; the Skill demonstrates its integration alongside PostgreSQL and Sequelize.

Use OpenAPI documentation to define endpoints, request/response schemas, and authentication requirements. This provides both developer reference and client-side code generation for construction APIs built with Express and PostgreSQL backends.

JWT-based role-based access control (RBAC) authenticates users and restricts endpoints by role—essential for construction platforms where plan managers, contractors, and admins need different permission levels across job workflows and contract data.
