API Flexibility Analysis
Scenario
Now that your team has a solid plan for connecting the client and server, the conversation has shifted to long-term API strategy. The default choice is a traditional REST API, but some team members have brought up GraphQL as a potential alternative. They argue it could solve common data-fetching problems and make the frontend development process faster.
Your tech lead has asked you to research the practical differences between REST and GraphQL. Your task is to prepare a document that compares the two, analyzes their respective trade-offs, and provides a recommendation on when to choose one over the other.
Instructions
This lab is a reading and reflection exercise. There is no coding involved. Your task is to carefully read the following articles comparing REST and GraphQL and then answer the reflection questions in a written document.
Task 1: Reading Assignment
Please read the following articles. They provide a detailed analysis of the strengths, weaknesses, and ideal use cases for both REST and GraphQL.
- Article 1: GraphQL vs REST: A Comprehensive Comparison
- Article 2: Is GraphQL Better Than REST? A Comparison
- Article 3: GraphQL vs REST: API Showdown
Focus on how the design of each API style impacts both the backend (implementation, caching) and the frontend (data fetching, performance).
Task 2: Written Reflection
After reading the articles, answer the following questions in a clear and concise manner. Your total response should be between 300 and 500 words.
-
The Over-fetching Problem: In your own words, explain the concepts of “over-fetching” and “under-fetching” in the context of a REST API. How does GraphQL’s query language inherently solve this problem?
-
Endpoint and Schema Philosophy: Compare the endpoint structure of a typical REST API with that of a GraphQL API. How does GraphQL’s strongly-typed schema benefit frontend developers?
-
Caching and Complexity: Caching is often cited as a major advantage of REST. Explain why caching is simpler in REST compared to GraphQL. What is a use case where the flexibility of GraphQL might outweigh its caching complexity?
Submission
- Create a new document (e.g., Google Doc, Word document, or a simple Markdown file in a GitHub repository).
- Address all three reflection questions clearly.
- Submit a link to your document.
Grading
This lab is worth 30 points. Your reflection will be graded based on the following criteria:
| Criteria | Description | Points |
|---|---|---|
| Clarity and Understanding | Your answers demonstrate a clear understanding of the concepts presented in the articles. | 10 |
| Depth of Analysis | You provide thoughtful and accurate explanations of the trade-offs between REST and GraphQL. | 15 |
| Completeness and Professionalism | All questions are answered, and the submission is well-written, clear, and within the word count limit. | 5 |
| Total | 30 |
