@kubb/plugin-svelte-query

Create primitives based on an operation.

Installation

bun

bun add -d @kubb/plugin-svelte-query

pnpm

pnpm add -D @kubb/plugin-svelte-query

npm

npm install --save-dev @kubb/plugin-svelte-query

yarn

yarn add -D @kubb/plugin-svelte-query

Options

output

Specify the export location for the files and define the behavior of the output.

output.path

Path to the output folder or file that will contain the generated code.

TIP

if output.path is a file, group cannot be used.

Type:	string
Required:	true
Default:	'hooks'

output.barrelType

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

TIP

Using propagate will prevent a plugin from creating a barrel file, but it will still propagate, allowing output.barrelType to export the specific function or type.

Type:	'all' | 'named' | 'propagate' | false
Required:	false
Default:	'named'

all

export * from "./gen/petService.ts"

named

export { PetService } from "./gen/petService.ts"

propagate

false

output.banner

Add a banner text in the beginning of every file.

Type:	string
Required:	false

output.footer

Add a footer text at the end of every file.

Type:	string
Required:	false

group

Grouping makes it possible to combine files in a folder based on specific type.

Imagine you have the following setup:

group: {
  type: 'tag',
  name({ group }){
    return `${group}Controller`
  }
}

That will create a structure like this:

.
├── src/
│   └── petController/
│   │   ├── addPet.ts
│   │   └── getPet.ts
│   └── storeController/
│       ├── createStore.ts
│       └── getStoreById.ts
├── petStore.yaml
├── kubb.config.ts
└── package.json

group.type

Define a type where to group the files on.

Type:	'tag'
Required:	true

• 'tag': Use of operation.getTags().at(0)?.name

group.name

Return the name of a group based on the group name, this will be used for the file and name generation.

Type:	(context: GroupContext) => string
Required:	false
Default:	(ctx) => '${ctx.group}Controller'

client

client.importPath

Path to the client import path that will be used to do the API calls.
It will be used as import client from '${client.importPath}'.
It allows both relative and absolute path but be aware that we will not change the path.

TIP

Use of default exports as export default client = ()=>{}

Type:	string
Required:	false
Default:	'@kubb/plugin-client/clients/axios'

client.dataReturnType

ReturnType that will be used when calling the client.

Type:	'data' | 'full'
Required:	false
Default:	'data'

• 'data' will return ResponseConfig[data].
• 'full' will return ResponseConfig.

'data'

export async function getPetById<TData>(
  petId: GetPetByIdPathParams,
): Promise<ResponseConfig<TData>["data"]> {
  ...
}

'full'

export async function getPetById<TData>(
  petId: GetPetByIdPathParams,
): Promise<ResponseConfig<TData>> {
  ...
}

client.baseURL

Allows you to set a custom base url for all generated calls.

Type:	string
Required:	false

paramsType

How to pass your params. Here you can switch between object-style parameters and inline parameters.

Type:	'object' | 'inline'
Required:	false
Default:	'inline'

TIP

When paramsType is set to 'object', pathParams will also be set to 'object'.

• 'object' will return the params and pathParams as an object.
• 'inline' will return the params as comma separated params.

'object'

export async function deletePet(
  {
    petId,
    headers,
  }: {
    petId: DeletePetPathParams['petId']
    headers?: DeletePetHeaderParams
  },
  config: Partial<RequestConfig> = {},
) {
...
}

'inline'

export async function deletePet(
  petId: DeletePetPathParams['petId'],
  headers?: DeletePetHeaderParams,
  config: Partial<RequestConfig> = {}
){
  ...
}

paramsCasing

How to style your params, by default no casing is applied.

Type:	'camelcase'
Required:	false
Default:	``

• 'camelcase' will use camelcase for the params names

'camelcase'

export async function deletePet(
  petId: DeletePetPathParams['pet_id'],
  headers?: DeletePetHeaderParams,
  config: Partial<RequestConfig> = {}
){
...
}

''

export async function deletePet(
  pet_id: DeletePetPathParams['pet_id'],
  headers?: DeletePetHeaderParams,
  config: Partial<RequestConfig> = {}
){
 ...
}

pathParamsType

How to pass your pathParams.

Type:	'object' | 'inline'
Required:	false
Default:	'inline'

• 'object' will return the pathParams as an object.
• 'inline' will return the pathParams as comma separated params.

'object'

export async function getPetById (
  { petId }: GetPetByIdPathParams,
) {
  ...
}

'inline'

export async function getPetById(
  petId: GetPetByIdPathParams,
) {
  ...
}

parser

Which parser should be used before returning the data.

Type:	'client' | 'zod'
Required:	false
Default:	'client'

• 'zod' will use @kubb/plugin-zod to parse the data.
• 'client' will return without parsing the data.
