--- description: 'Enforce consistent usage of type exports.' --- > 🛑 This file is source code, not the primary documentation location! 🛑 > > See **https://typescript-eslint.io/rules/consistent-type-exports** for documentation. TypeScript allows specifying a `type` keyword on exports to indicate that the export exists only in the type system, not at runtime. This allows transpilers to drop exports without knowing the types of the dependencies. > See [Blog > Consistent Type Exports and Imports: Why and How](/blog/consistent-type-imports-and-exports-why-and-how) for more details. ## Examples ### ❌ Incorrect ```ts interface ButtonProps { onClick: () => void; } class Button implements ButtonProps { onClick = () => console.log('button!'); } export { Button, ButtonProps }; ``` ### ✅ Correct ```ts interface ButtonProps { onClick: () => void; } class Button implements ButtonProps { onClick = () => console.log('button!'); } export { Button }; export type { ButtonProps }; ``` ## Options ### `fixMixedExportsWithInlineTypeSpecifier` When this is set to true, the rule will autofix "mixed" export cases using TS 4.5's "inline type specifier". If you are using a TypeScript version less than 4.5, then you will not be able to use this option. For example the following code: ```ts const x = 1; type T = number; export { x, T }; ``` With `{fixMixedExportsWithInlineTypeSpecifier: true}` will be fixed to: ```ts const x = 1; type T = number; export { x, type T }; ``` With `{fixMixedExportsWithInlineTypeSpecifier: false}` will be fixed to: ```ts const x = 1; type T = number; export type { T }; export { x }; ``` ### ❌ Incorrect ```ts export { Button } from 'some-library'; export type { ButtonProps } from 'some-library'; ``` ### ✅ Correct ```ts export { Button, type ButtonProps } from 'some-library'; ``` ## When Not To Use It - If you specifically want to use both export kinds for stylistic reasons, you can disable this rule. - If you use `--isolatedModules` the compiler would error if a type is not re-exported using `export type`. If you also don't wish to enforce one style over the other, you can disable this rule.
