# 2. Fetch Applications, Data Plugs and Data Debits

### Applications

#### Get all the apps

The are 2 ways to fetch applications:

1. With default options.

**Example:**

```typescript
try {
    const result = await hat.applications().getAllDefault();

    if (result.parsedBody) {
        // result.parsedBody contains an array of Applications.
    }
} catch (error) {
    // The request failed...
}
```

2\. With custom options.

**Example:**

```typescript
// In custom options you can specify the following parameters: "ordering", "orderBy", "take", "skip"

const options = {
    ordering: "descending",
    orderBy: "name"
};

try {
    const result = await hat.applications().getAll(options);

    if (result.parsedBody) {
        // result.parsedBody contains an array of Applications.
    }
} catch (error) {
    // The request failed...
}
```

#### Get an application with a specific ID

**Example:**

```typescript
try {
    const result = await hat.applications().getById("testhatapp");

    if (result.parsedBody) {
        // result.parsedBody contains the application.
    }
} catch (error) {
    // The request failed...
}
```

#### Get an application status

| Parameters  | Type                                                                                                        |
| ----------- | ----------------------------------------------------------------------------------------------------------- |
| application | [HatApplication](https://docs.dataswift.io/guides/application-management/01-application-information-format) |

**Example:**

```typescript
const status = hat.applications().getAppStatus(application);

console.log(status);
// Will print one of  'goto' | 'running' | 'fetching' | 'failing' | 'untouched' | 'update';
```

#### Generate a Data Plug setup URL

You can generate a URL to redirect the user to setup a Data Plug.

| Parameters  | Type                                                                                                        |
| ----------- | ----------------------------------------------------------------------------------------------------------- |
| application | [HatApplication](https://docs.dataswift.io/guides/application-management/01-application-information-format) |
| redirect    | string                                                                                                      |
| fallback    | string                                                                                                      |

**Example:**

```typescript
const redirectUrl = "https://myapp.dataswift.io/app/redirect";
const fallbackUrl = "https://myapp.dataswift.io/app/fallback";
const generatedUrl = hat.applications().getSetupUrl(application, redirectUrl, fallbackUrl);

console.log(generatedUrl); 
// Will print: https://testing.hubat.net/#/hatlogin?name=facebook&fallback=https://myapp.dataswift.io/app/fallback&redirect=https://facebook.hubofallthings.com%3Fredirect=https://myapp.dataswift.io/app/redirect

window.location.href = generatedUrl; // Navigate the user to setup the Data Plug.
```
