# Axios API Calls

### Axios API call using SWR

Product values have been initialized using useSWR with Axios fetcher, like below:

{% tabs %}
{% tab title="NEXT (TS)" %}
{% code title="src/api/products.ts" %}

```typescript
export function useGetRelatedProducts(id: string) {
  const URL = [endpoints.related, { id, endpoints: 'products' }];

  const { data, isLoading, error, isValidating } = useSWR(URL, fetcherPost, {
    revalidateIfStale: false,
    revalidateOnFocus: false,
    revalidateOnReconnect: false
  });

  const memoizedValue = useMemo(
    () => ({
      relatedProducts: data as Products[],
      relatedProductsLoading: isLoading,
      relatedProductsError: error,
      relatedProductsValidating: isValidating,
      relatedProductsEmpty: !isLoading && !data?.length
    }),
    [data, error, isLoading, isValidating]
  );

  return memoizedValue;
}
```

{% endcode %}
{% endtab %}

{% tab title="NEXT (JS)" %}
{% code title="src/api/products.js" %}

```javascript
export function useGetRelatedProducts(id) {
  const URL = [endpoints.related, { id, endpoints: 'products' }];

  const { data, isLoading, error, isValidating } = useSWR(URL, fetcherPost, {
    revalidateIfStale: false,
    revalidateOnFocus: false,
    revalidateOnReconnect: false
  });

  const memoizedValue = useMemo(
    () => ({
      relatedProducts: data,
      relatedProductsLoading: isLoading,
      relatedProductsError: error,
      relatedProductsValidating: isValidating,
      relatedProductsEmpty: !isLoading && !data?.length
    }),
    [data, error, isLoading, isValidating]
  );

  return memoizedValue;
}
```

{% endcode %}
{% endtab %}
{% endtabs %}

You can mutate the product list with an Axios call, like below,

{% tabs %}
{% tab title="NEXT (TS)" %}
{% code title="src/api/products.ts" %}

```typescript
export async function productFilter(filter: ProductsFilter) {
  const newProducts = await axios.post(endpoints.key + endpoints.filter, { filter });

  // to update local state based on key
  mutate(
    endpoints.key + endpoints.list,
    (currentProducts: any) => {
      return {
        ...currentProducts,
        products: newProducts.data
      };
    },
    false
  );
}
```

{% endcode %}
{% endtab %}

{% tab title="NEXT (JS)" %}
{% code title="src/api/products.js" %}

```javascript
export async function productFilter(filter) {
  const newProducts = await axios.post(endpoints.key + endpoints.filter, { filter });

  // to update local state based on key
  mutate(
    endpoints.key + endpoints.list,
    (currentProducts) => {
      return {
        ...currentProducts,
        products: newProducts.data
      };
    },
    false
  );
}
```

{% endcode %}
{% endtab %}
{% endtabs %}

### Set the default axios baseURL for calling the API

Open `next.config.js` file and edit NEXT\_APP\_API\_URL.

{% code title="next.config.js" %}

```javascript
env: {
    NEXT_APP_API_URL:
    ..
}
```

{% endcode %}

Axios has been configured in the folder **`src\utils\axios`**

### Example 1: With baseUrl

{% tabs %}
{% tab title="NEXT (TS)" %}
{% code title="src/utils/axios.ts" %}

```typescript
import axios, { AxiosRequestConfig } from 'axios';
import { getSession } from 'next-auth/react';

const axiosServices = axios.create({ baseURL: process.env.NEXT_APP_API_URL });


// ==============================|| AXIOS - FOR MOCK SERVICES ||============================== //

axiosServices.interceptors.request.use(
  async (config) => {
    const session = await getSession();
    if (session?.token.accessToken) {
      config.headers['Authorization'] = `Bearer ${session?.token.accessToken}`;
    }
    return config;
  },
  (error) => {
    return Promise.reject(error);
  }
);
```

{% endcode %}
{% endtab %}

{% tab title="NEXT (JS)" %}
{% code title="src/utils/axios.js" %}

```javascript
import axios from 'axios';
import { getSession } from 'next-auth/react';

const axiosServices = axios.create({ baseURL: import.meta.env.VITE_APP_API_URL || 'http://localhost:3010/' });

// ==============================|| AXIOS - FOR MOCK SERVICES ||============================== //

axiosServices.interceptors.request.use(
  async (config) => {
    const session = await getSession();
    if (session?.token.accessToken) {
      config.headers['Authorization'] = `Bearer ${session?.token.accessToken}`;
    }
    return config;
  },
  (error) => {
    return Promise.reject(error);
  }
);
```

{% endcode %}
{% endtab %}
{% endtabs %}

### Example 2: Without baseUrl

You can set the entire URL in the Axios request. Do not use common Axios instances  **`src\utils\axios`** instead, use the Axios library.

{% tabs %}
{% tab title="NEXT (TS)" %}
{% code title="src\utils\axios.ts" %}

```typescript
import { useCallback, useState } from 'react';

// third-party
import axios from 'axios';

// ==============================|| AXIOS - USER ||============================== //

function UserList() {
  const [users, setUsers] = useState([]);

  const getUsers = useCallback(async () => {
    try {
      const response = await axios.get('https://www.domain-xyz.com/api/users');
      setUsers(response.data.users);
    } catch (error) {
      console.log(error);
    }
  }, []);

  useEffect(() => {
    getUsers();
  }, [getUsers]);

  return (
    <div>
      {users.map((user: UserProfile[], index: number) => (
        <div key={index}>{user.name}</div>
      ))}
    </div>
  );
}
```

{% endcode %}
{% endtab %}

{% tab title="NEXT (JS)" %}
{% code title="src\utils\axios.js" %}

```javascript
import { useCallback, useState } from 'react';

// third-party
import axios from 'axios';

// ==============================|| AXIOS - USER ||============================== //

function UserList() {
  const [users, setUsers] = useState([]);

  const getUsers = useCallback(async () => {
    try {
      const response = await axios.get('https://www.domain-xyz.com/api/users');
      setUsers(response.data.users);
    } catch (error) {
      console.log(error);
    }
  }, []);

  useEffect(() => {
    getUsers();
  }, [getUsers]);

  return (
    <div>
      {users.map((user, index) => (
        <div key={index}>{user.name}</div>
      ))}
    </div>
  );
}
```

{% endcode %}
{% endtab %}
{% endtabs %}
