## Breaking change :warning:

### 2022/03/07

Since openapi2aspida >= `0.18.0` , decision whether to be required follows the OpenAPI spec correctly. Dropping the support for original implementation, that was defaulting to required.

### 2021/03/15

Since openapi2aspida >= `0.16.0` , requires TypeSciprt 3.8 or higher for Type-Only Imports.

### 2020/11/26

Since openapi2aspida >= `0.14.0` , request headers are forced to be optional.

### 2020/11/14

Since openapi2aspida >= `0.13.0` , optional for aspida only if the 'required' property of OpenAPI is set to `false`.

## Getting Started

Compatible with yaml/json of OpenAPI3.0/Swagger2.0

```sh
$ mkdir petstore-api
$ cd petstore-api
$ npx openapi2aspida -i https://petstore.swagger.io/v2/swagger.json # or ../local-swagger.yaml
# api/$api.ts was built successfully.

$ npm init -y
$ npm install @aspida/axios axios typescript ts-node @types/node
```

`index.ts`

```ts
import axiosClient from "@aspida/axios"
import api from "./api/$api"
import type { Pet } from "./api/@types"
;(async () => {
  const client = api(axiosClient())
  const petId = 100
  const body: Pet = {
    id: petId,
    name: "hoge",
    photoUrls: [],
    status: "available"
  }

  await client.pet.$post({ body })
  const pet = await client.pet._petId(petId).$get()
  console.log(pet)
})()
```

`package.json`

```json
{
  "scripts": {
    "start": "ts-node index.ts"
  }
}
```

```sh
$ npm start
# { id: 100, name: 'hoge', photoUrls: [], tags: [], status: 'available' }
```

## Build from config file

Create config file in project root

`aspida.config.js`

```js
module.exports = {
  input: "api", // "input" of aspida is "output" for openapi2aspida
  outputEachDir: true, // Generate $api.ts in each endpoint directory
  openapi: { inputFile: "https://petstore.swagger.io/v2/swagger.json" }
}
```

```sh
$ npx openapi2aspida
```

## Cli options

### `-i`, `--input`

path to an OpenAPI spec file for input

### `-o`, `--outputdir`

can change aspida output directory

### `-c`, `--config`

path to an aspida config file

### `--version`

displays version of openapi2aspida

### example

```bash
npx openapi2aspida -i=openApi/sample.yaml -o=lib/api/sample
```
