API design principles

API designers generally fall into either a REST or RPC type. The REST type prefers to name paths after resources like "customers", and "payments". And the REST type relies on HTTP methods, like GET, to indicate the action on that resource. It would be considered a design fail to make the path "getcustomers" or "get-customers" or any variation on that. If you're aiming to design RESTful resources, then consider this rule your friend.

To reduce false positives, use the splitIntoWords option. Imagine a world-famous rock band, the Redockers, and they have an API powering their music tour with one resource "posters". With the splitIntoWords option enabled, "posters" is identified as a resource and does not trigger a false positive, even though it contains the word post.

Configuration

Option Type Description
severity string Possible values: off, warn, error. Default off (in recommended configuration).
splitIntoWords boolean Matches http verbs when the string is split into words based on casing. This can reduce false positives. Default false.

An example configuration:

Copy
Copied
rules:
  no-http-verbs-in-paths: error

An example configuration with splitIntoWords enabled:

Copy
Copied
rules:
  no-http-verbs-in-paths:
    severity: error
    splitIntoWords: true

Examples

Given this configuration:

Copy
Copied
rules:
  no-http-verbs-in-paths: error

Example of an incorrect path:

Copy
Copied
paths:
  /getcustomers:
    $ref: ./paths/customer.yaml

Example of a correct path:

Copy
Copied
paths:
  /customers:
    $ref: ./paths/customer.yaml

Given the following configuration:

Copy
Copied
rules:
  no-http-verbs-in-paths:
    severity: error
    splitIntoWords: true

Example of an incorrect path:

Copy
Copied
paths:
  /getCustomers:
    $ref: ./paths/customer.yaml

Example of a correct path:

Copy
Copied
paths:
  /getcustomers:
    $ref: ./paths/customer.yaml

This last example wouldn't trigger an error because the casing doesn't split "get" into its own word.
