How does URI versioning work in Laravel routes?

You include the version in the route URL, like /api/v1/users. Laravel routes are grouped by version prefix to separate versions cleanly.

What is a benefit of using header versioning over URI versioning?

Header versioning keeps URLs clean and stable, hiding version details from the URL and allowing version changes without changing routes.

How can Laravel middleware help with API versioning?

Middleware can inspect request headers or parameters to route requests to the correct version controller, centralizing version logic.

Which of these is NOT a common API versioning pattern?

A Cookie versioning

B Header versioning

C URI versioning

D Query parameter versioning

Cookie versioning is not a common pattern for API versioning. URI, header, and query parameter versioning are widely used.

In Laravel, how do you typically define routes for different API versions?

A Using different route files for each version

B Using route groups with version prefixes

C Using different controllers without route changes

D Using environment variables

Laravel uses route groups with version prefixes like /api/v1 to organize routes by API version.

What is a downside of URI versioning?

A It is hard to implement in Laravel

B It hides version info from clients

C It requires clients to change URLs when upgrading

D It does not support multiple versions

URI versioning requires clients to update URLs when switching API versions, which can be inconvenient.

Which Laravel feature can help route requests based on API version in headers?

A Blade templates

B Service providers

C Eloquent models

D Middleware

Middleware can read headers and direct requests to the correct version controller.

Why might query parameter versioning be less preferred?

A It can be ignored by caches

B It is not supported by Laravel

C It makes URLs longer and less clean

D It requires special headers

Query parameters can be ignored by some caches, causing caching issues for different API versions.

Explain how you would implement URI versioning in a Laravel API.

Think about how Laravel routes can be grouped and prefixed.

Describe the advantages and disadvantages of header versioning for APIs.

Consider how version info is hidden or shown to clients.
