eslint-plugin-perfectionist/dist/utils/get-enum-members.js

ESLint plugin for sorting various data such as objects, imports, types, enums, JSX props, etc.

/**
 * Retrieves enum members from a TypeScript enum declaration node.
 *
 * Handles AST shape changes in TS-ESTree `@typescript-eslint/types`:
 *
 * - Newer parser versions wrap enum members in `body.members` and deprecate
 *   `members` on the enum node.
 * - Older parser versions expose members directly on the enum node as `members`.
 *   The fallback keeps backward compatibility with older parser releases.
 *
 * @example
 *
 * ```ts
 * enum Color {
 *   Red = 'RED',
 *   Green = 'GREEN',
 *   Blue = 'BLUE',
 * }
 * // Returns array of three TSEnumMember nodes
 * ```
 *
 * @param value - TypeScript enum declaration AST node.
 * @returns Array of enum member nodes.
