oxc/no-const-enum

A const enum doesn't exist at runtime. TypeScript replaces each use with the member's value, and to do that it has to read the file that declares the enum. A tool that compiles one file at a time can't do that for an imported enum. If the enum is in a published .d.ts file, its values are copied into every package compiled against it, and they go stale when the enum changes.

--fix removes const, which makes it a regular enum.

Configure#

Off by default. To turn it on:

[lint.rules]
"oxc/no-const-enum" = "error" # or "warn"

Examples#

export const enum Status {
  Active,
  Archived,
}

export enum Status {
  Active,
  Archived,
}

An object with as const gives you plain values without an enum:

export const Status = {
  Active: 0,
  Archived: 1,
} as const;
