Resource-based URL design in Express - Cheat Sheet & Quick Revision

Recall & Review

What is resource-based URL design in web development?

It is a way to organize URLs so each URL represents a resource (like users or products) instead of actions. This makes URLs simple and easy to understand, like /users or /products/123.

Why use nouns instead of verbs in resource-based URLs?

Nouns represent resources (things) and verbs represent actions. Using nouns keeps URLs consistent and lets HTTP methods (GET, POST, PUT, DELETE) define the action clearly.

Example: What HTTP method and URL would you use to update a user with ID 5?

Use PUT /users/5. PUT means update, and /users/5 points to the user resource with ID 5.

How does Express help implement resource-based URL design?

Express lets you define routes with URL patterns and HTTP methods. For example, app.get('/users', ...) handles getting all users, and app.post('/users', ...) handles creating a user.

What is the benefit of using resource-based URLs for API clients?

Clients can predict URLs and actions easily. They know to use GET to read, POST to create, PUT to update, and DELETE to remove resources, making APIs easier to use and understand.

Which URL best follows resource-based design for accessing a list of books?

A /books/list

B /getBooks

C /books

D /fetchBooks

Resource-based URLs use nouns like /books. Verbs like get or fetch are avoided in URLs.

Which HTTP method is used to delete a resource in resource-based URL design?

A DELETE

B POST

C GET

D PUT

DELETE method is used to remove a resource.

In Express, how do you define a route to update a user with ID parameter?

A app.put('/users/:id', ...)

B app.delete('/users/:id', ...)

C app.post('/users/:id', ...)

D app.get('/users/:id', ...)

PUT method with '/users/:id' is used to update a user.

What does the URL /products/123 represent in resource-based design?

A A search for products

B A list of products

C An action to create a product

D A product with ID 123

It points to the product resource with ID 123.

Why avoid verbs in resource-based URLs?

A Because verbs are not allowed in URLs

B Because HTTP methods already define actions

C Because verbs are harder to type

D Because verbs slow down the server

HTTP methods like GET, POST, PUT, DELETE define actions, so URLs use nouns for resources.

Explain how resource-based URL design organizes URLs and HTTP methods in an Express app.

Think about how URLs and HTTP verbs work together.

Describe the benefits of using resource-based URL design for API users and developers.

Consider how it helps both sides communicate.
