npm

npm install @kubb/swagger-ts @kubb/swagger

yarn

Options

output

output.path

Relative path to save the TypeScript types.
When output is a file it will save all models inside that file else it will create a file per schema item.

INFO

Type: string

const plugin = pluginTs({
  output: {
    path: './models',
  },
})

output.exportAs

Name to be used for the export * as from './'

INFO

Type: string

import { pluginTs } from '@kubb/swagger-ts'

const plugin = pluginTs({
  output: {

    exportAs: 'models',
  },
})

output.extName

Add an extension to the generated imports and exports, default it will not use an extension

INFO

Type: string

import { pluginTs } from '@kubb/swagger-ts'

const plugin = pluginTs({

output.exportType

Define what needs to exported, here you can also disable the export of barrel files

INFO

Type: 'barrel' | 'barrelNamed' | false
