Enums are not usable as values after updating from v2 to v3

[wnkchristopher]

I updated kubb from "2.10.0" to "3.10.12". I used with v2 the following kubb.config file for my type generation:

import { defineConfig } from '@kubb/core';
import createSwagger from '@kubb/swagger';
import createSwaggerTS from '@kubb/swagger-ts';

const PATH = 'path';

export default defineConfig({
    root: '.',
    input: {
        path: './src/api/swagger.json',
    },
    output: {
        path: './src/api/generated',
    },
    plugins: [
        createSwagger({
            output: false,
        }),
        createSwaggerTS({
            enumType: 'constEnum',
            include: [{ type: 'path', pattern: FORM_PATH }],
        }),
    ],
});

After the update I'm using

import { defineConfig } from '@kubb/core';
import { pluginOas } from '@kubb/plugin-oas';
import { pluginTs } from '@kubb/plugin-ts';

const PATH = 'path';

export default defineConfig({
    root: '.',
    input: {
        path: './src/api/swagger.json',
    },
    output: {
        path: './src/api/generated',
        extension: {
            '.ts': '',
        },
        barrelType: 'all',
    },

    plugins: [
        pluginOas({
            generators: [],
        }),
        pluginTs({
            enumType: 'constEnum',
            include: [{ type: 'path', pattern: FORM_PATH }],
            output: {
                path: './types',
                barrelType: 'all',
            },
            enumSuffix: '',
        }),
    ],
});

Problem after updating

I noticed that all barrel files now use export type * from './file' instead of export * from './file'.

This causes TypeScript errors when using enums:

export enum Status {
  Active = 'active',
  Inactive = 'inactive'
}

If the barrel exports this file using export type *, any consumer code will throw:

'Status' cannot be used as a value because it was exported using 'export type'.ts(136)

Why this is a problem

• Enums (and other runtime values) must be exported using export * – otherwise they are not available at runtime.
• export type * is only safe for type-only modules like interfaces and type aliases.
• There's currently no configuration option in @kubb/plugin-ts to change this behavior.

Workaround

I’m currently using a post-processing script to replace export type * with export *, but this feels like a hack and adds unnecessary build complexity.

Question

Is there a intended way to handle this problem? Is this an issue?

@wnkchristopher I added the following issue so we could have a look on what is going wrong: #1749. This will probably be an easy fix.

Thanks for using Kubb!

@wnkchristopher This will be resolved as part of Kubb v3.10.16

[wnkchristopher]

Thanks @stijnvanhulle .

Do you already know when v3.10.16 gets published?
