Building RESTful APIs Using Node.js and Express

NIIT compares building an API directly in Node.js with using Express. Documentation and security then give the endpoints a wider application context. This is a focused API-development choice for learners ready to connect backend requests with predictable, documented responses.

What you will learn

• Build REST endpoints with Node.js and Express.
• Document an API’s request and response behavior.
• Explain JWT and OAuth security concepts.

Who this suits

Learners ready to work with server-side JavaScript and HTTP; preview the mixed-level exercises before enrolling.

Before you enroll

Preview the Node.js, package and database versions used in the lessons. Authentication, hosting and payment examples need additional testing before real deployment. Start with a local application and fictional data, then check the current documentation when a dependency behaves differently.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Document a fictional API and write example success and error responses, then identify where authentication and authorization checks belong.
