### Implement onRequest Interceptor

Source: https://unjs.io/packages/ofetch

Modifies request options or performs logging immediately before the fetch call is executed.

```javascript
await ofetch("/api", {
  async onRequest({ request, options }) {
    // Log request
    console.log("[fetch request]", request, options);

    // Add `?t=1640125211170` to query search params
    options.query = options.query || {};
    options.query.t = new Date();
  },
});
```

--------------------------------

### Adding headers to requests

Source: https://unjs.io/packages/ofetch

Include custom headers in a request by passing a headers object to the options.

```javascript
await ofetch("/movies", {

    Accept: "application/json",
    "Cache-Control": "no-cache",
  },
});
```

--------------------------------

await ofetch("/api", {
  async onResponse({ request, response, options }) {
    // Log response
    console.log("[fetch response]", request, response.status, response.body);
  },
});
```

--------------------------------

### Implement onResponseError Interceptor

Source: https://unjs.io/packages/ofetch

Handles cases where the fetch request completes but the response status indicates an error (response.ok is false).

```javascript
await ofetch("/api", {
  async onResponseError({ request, response, options }) {
    console.log(
      "[fetch response error]",
      request,
      response.status,

  retryDelay: 500, // ms
});
```

--------------------------------

### Apply TypeScript Generics

Source: https://unjs.io/packages/ofetch

Enables type assistance for the response object by passing a generic type to the ofetch call.

```typescript
const article = await ofetch<Article>(`/api/article/${id}`);
// Auto complete working with article.id
```

--------------------------------

### Interceptors

Source: https://unjs.io/packages/ofetch

Lifecycle hooks to intercept and modify requests or handle responses and errors.

```APIDOC
## Interceptors

### onRequest({ request, options })

### onRequestError({ request, options, error })
Called when the fetch request fails.

### onResponse({ request, options, response })
Called after the fetch call and body parsing.

### onResponseError({ request, options, response })
Called when the fetch call completes but the response is not successful (response.ok is false).
```

--------------------------------

### Set Request Timeout

Source: https://unjs.io/packages/ofetch

Defines a duration in milliseconds after which the request will be automatically aborted.

```javascript
await ofetch("http://google.com/404", {
  timeout: 3000, // Timeout after 3 seconds
});
```

--------------------------------

### Implement onRequestError Interceptor

Source: https://unjs.io/packages/ofetch

Handles errors that occur during the initiation of the fetch request.

```javascript
await ofetch("/api", {
  async onRequestError({ request, options, error }) {
    // Log error

await ofetch("/url", { ignoreResponseError: true });
```

--------------------------------

### Catch Error Response Data
