Reviews summary

Practical rest api with express foundation

According to students, "Building a REST API in JavaScript with Express" is a solid introduction for those new to backend development with Node.js. Many found the instructor's explanations clear and concise, and appreciated the hands-on coding exercises and practical examples, especially the use of Postman for testing. This course is frequently praised for providing a strong foundational understanding of REST APIs and Express. However, some learners noted that the course could benefit from updates regarding dependency versions and best practices, occasionally requiring troubleshooting. A few also wished for more advanced topics like authentication or deeper error handling to build production-ready applications, suggesting it serves more as a stepping stone than a comprehensive guide for experienced developers.

Excellent for beginners to build a foundational understanding.

"This course is a solid introduction to building REST APIs with Express. Overall very valuable."

"Highly recommend for anyone starting with Node.js and APIs."

"This course delivers exactly what it promises. Clear, concise, and hands-on. I finally feel confident building a basic API."

"A good foundational course for REST APIs with Node.js and Express. It sets a good foundation."

Provides practical examples and hands-on coding activities.

"I appreciated the use of Postman for testing. It's a great starting point for backend development."

"The hands-on coding really helped solidify my understanding of the asynchronous nature and core principles of REST."

"I particularly enjoyed the practical application of Express routes and middleware."

The instructor provides concise and easy-to-follow explanations.

"The instructor explains concepts clearly and provides practical examples."

"As a beginner, I found the explanations incredibly easy to follow. The hands-on coding really helped solidify my understanding..."

"The explanations were concise yet thorough. This course gave me the confidence to start my own API projects."

"The instructor's teaching style is very engaging. The testing with Postman part was especially useful."

Requires manual updates due to outdated package versions.

"The course covers the basics, but it feels a bit dated in terms of dependency versions and some best practices."

"I had to spend extra time updating packages and troubleshooting deprecated methods, which was frustrating."

"The course setup had some issues. I ran into several outdated package warnings which required manual intervention."

Does not cover advanced topics or production-ready features.

"Some parts felt a bit rushed, especially error handling, but overall very valuable."

"My main feedback is that it could use more advanced topics like authentication, authorization, or database integration beyond simple mocks."

"While it introduces Express, it doesn't go deep enough into error handling or security aspects which are critical for production APIs."

"It sets a good foundation, but be prepared to supplement with other materials for production-ready applications."
