# Examples

## Devices

### Get all devices in the account

```javascript
const allDevices = await Ubidots.devices.all();
```

### Get the first device in the account

```javascript
const firstDevice = await Ubidots.devices.first();
// This is equivalent to
const firstDevice = (await Ubidots.devices.all())[0];
```

### **Get the first 1000 devices in the account**

```javascript
const devicesPaginated = (await Ubidots.devices.paginate(1, 1000)).results
```

### Get the `lastActivity` field from devices

```javascript
 const allDevicesLastActivity = await Ubidots.devices.addRawParam('fields', 'lastActivity').get();
```

### Get the `lastActivity` and `variablesCount` fields from devices

```javascript
const device = await Ubidots.devices.addRawParams(
  { 
      fields: 'lastActivity,variablesCount'
  }
 ).get();
```

### Get the `lastActivity` and `variablesCount` fields from a specific device using its label

```javascript
const device = await Ubidots.devices.addRawParams(
  { 
      label: 'temperature_sensor',
      fields: 'lastActivity,variablesCount'
  }
).get();
```

### Get a device by label or ID

```javascript
// By label
const temperatureDevice = await Ubidots.devices.where('label').exact('temperature_device_1').first();

// By id
const temperatureDevice = await Ubidots.devices.where('id').exact('some-id').first();
```

### Get a set of devices based on their type

```javascript
const devicesByType = await Ubidots.devices.where('deviceType').exact('temperature-devices').get();
```

## Variables

### **Get all the variables in the account**

```javascript
const allVariables = await Ubidots.variables.all();
```

### **Get the first variable in the account:**

```javascript
const firstVariable = await Ubidots.variables.first();
// This is equivalent to
const firstVariable = (await Ubidots.variables.all())[0];
```

### **Get the first 100 variables in the account:**

```javascript
const variablesPaginated = (await Ubidots.variables.paginate(1, 100)).results;
// Equivalent to
const variablesPaginated = (await Ubidots.variables.paginate()).results;
```

### **Get the `lastActivity` field from variables**

```javascript
const allVariablesLastActivity = await Ubidots.variables.addRawParam('fields', 'lastActivity').get();
```

### **Get the `lastActivity` and `label` fields from all variables**

```javascript
const variables = await Ubidots.variables.addRawParams(
  { 
    fields: 'lastActivity,label'
  }
).get();
```

### **Get the `lastActivity` and `label` fields from a specific variable**

```javascript
const variables = await Ubidots.variables.addRawParams(
  { 
    id: '6452a727df1a8e000c103fce',
    fields: 'lastActivity,label'
  }
).get();
```

### **Get a variable by ID:**

```javascript
const variableById = await Ubidots.variables.where('id').exact('6595770b9de79b000dce0eae').first();
```

### **Get a set of variables based on their label:**

<pre class="language-javascript"><code class="lang-javascript"><strong>const variablesByLabel = await Ubidots.variables.where('label').exact('temperature').get();
</strong></code></pre>

### Send data

First, get the device object and then the variable you want to send data to:

```javascript
// Get the device object
const temperatureDevice = await Ubidots.devices.where('label').exact('temperature_device_1').first();
// Get the variable object
const temperatureVariable = await temperatureDevice.variables.where('label').exact('temperature').first();
```

* Send a value:

  ```javascript
  temperatureVariable.sendDot(34);
  ```
* Send a value with timestamp:

  ```javascript
  temperatureVariable.sendDot(40, new Date().getTime());
  ```
* Send a value with timestamp and context:

  ```javascript
  temperatureVariable.sendDot(4, new Date().getTime(), { status: 'cold' });

  ```

## Get all the users in the account

```javascript
const allUsers = await Ubidots.users.all();
```

## Get all the organizations in the account <a href="#get-all-organizations-in-the-account" id="get-all-organizations-in-the-account"></a>

```javascript
const allOrganizations = await Ubidots.organizations.all();
```

## Get all the devices assigned to an organization <a href="#get-all-devices-assigned-to-an-organization" id="get-all-devices-assigned-to-an-organization"></a>

```javascript
const org = await Ubidots.organizations.where('id').exact('668fffcd88e37d000da10dd0').first();
const orgDevices = await org.devices.all();
orgDevices.forEach(device => {
  // Do something with each device
});
```

## Get all the dashboards in the account <a href="#get-all-dashboards-in-the-account" id="get-all-dashboards-in-the-account"></a>

```javascript
const allDashboards = await Ubidots.dashboards.all();
```
