sort-switch-case

Enforce sorted switch case statements.

Switch statements with numerous cases can quickly become cumbersome and hard to navigate. With this rule, you can easily locate specific cases and ensure that your codebase adheres to a predictable and standardized format.

This practice contributes to a more readable and maintainable codebase, allowing developers to quickly understand and modify the logic without getting lost in a jumble of unsorted case clauses.

By integrating this rule into your ESLint configuration, you can focus on the functionality of your code, confident that your switch statements are consistently structured and easy to manage.

Options

This rule accepts an options object with the following properties:

type

default: 'alphabetical'

Specifies the sorting method.

  • 'alphabetical' — Sort items alphabetically (e.g., “a” < “b” < “c”).
  • 'natural' — Sort items in a natural order (e.g., “item2” < “item10”).
  • 'line-length' — Sort items by the length of the code line (shorter lines first).

order

default: 'asc'

Determines whether the sorted items should be in ascending or descending order.

  • 'asc' — Sort items in ascending order (A to Z, 1 to 9).
  • 'desc' — Sort items in descending order (Z to A, 9 to 1).

ignoreCase

default: true

Controls whether sorting should be case-sensitive or not.

  • true — Ignore case when sorting alphabetically or naturally (e.g., “A” and “a” are the same).
  • false — Consider case when sorting (e.g., “A” comes before “a”).
