# Datalogic Cordova Plugin

Library that exposes the [Datalogic Android (Java) SDK](https://github.com/datalogic/datalogic-android-sdk) as a [Cordova plugin](https://cordova.apache.org/plugins/?q=cordova-plugin-datalogic). It lets you receive barcode data from the scanner, as well as configure various scanner and device settings. It is available as a npm package for easy consumption here: [@datalogic/cordova-plugin-datalogic](https://www.npmjs.com/package/@datalogic/cordova-plugin-datalogic).

## Installation

You can install the plugin from the `npm` registry as follows:

```bash
npm i @datalogic/cordova-plugin-datalogic
```

***...or*** use the following Cordova CLI command:

```bash
cordova plugin add @datalogic/cordova-plugin-datalogic
```

***or,*** if you are using ionic, this ionic command:

```bash
ionic cordova plugin add @datalogic/cordova-plugin-datalogic
```

***or,*** if you are using PhoneGap CLI, this phonegap command:

```bash
phonegap plugin add @datalogic/cordova-plugin-datalogic

## Publish new version

Install and use the [np tool](https://github.com/sindresorhus/np):

``` bash
npm install --global np
np
```

## Sample apps

Several Ionic sample applications are provided to demonstrate using the plugin. You can [find them here](https://github.com/datalogic/ionic-samples).

## API Reference

All functions are asynchronous. All functions will, at a minimum, include `successCallback` and `errorCallback` parameters, both of which are callback functions.

* `successCallback` will be called in normal cases, and will return an appropriate JSON `object`.

* `errorCallback` will be called when there was an error, and will return a single error `string`.

### Namespaces

| Namespace | Description
|-----------|------------
| [barcodeManager](#barcodeManager) | receive barcode data
| [autoScanTrigger](#autoScanTrigger) | work the the autoscan features
| [keyboardManager](#keyboardManager) | set usable device triggers
| [ledManager](#ledManager) | control device LEDs
| [scannerProperties](#scannerProperties) | define availabled symbologies

### barcodeManager

---

| Function | Description
|----------|------------
| [addReadListener](#addreadlistenersuccesscallback-errorcallback-object) | Register to recieve barcode data on each scan.
| [pressTrigger](#presstriggersuccesscallback-errorcallback-object) | Simulate a trigger button press.
| [releaseTrigger](#releasetriggersuccesscallback-errorcallback-object) | Simulate a trigger button release.

#### .addReadListener(`successCallback`, `errorCallback`): Object

Register to recieve barcode data on each scan. `successCallback` will be called ***every time*** a barcode is successfully scanned. Therefore, you will typically only need to call `barcodeManager.addReadListener()` *once* in your application.

##### Response

* `barcodeData` : `string` - the barcode data scanned.
* `barcodeType` : `string` - will be one of the `BarcodeID` values defined in the [BarcodeID class](https://github.com/datalogic/datalogic-android-sdk/blob/master/sdk/src/main/java/com/datalogic/decode/BarcodeID.java) in the [Datalogic Android SDK](https://github.com/datalogic/datalogic-android-sdk).

```json
{
   "barcodeData": "EUG2997",
   "barcodeType": "CODE128"
}
```

##### Example

```js
declare let barcodeManager : any;
...
barcodeManager.addReadListner(
   (data) => {
     parsedData = JSON.parse(data);
     alert(parsedData.barcodeData + ", " + parsedData.barcodeType);
   },
   (err)=>{ alert(err); }
);
```

#### .pressTrigger(`successCallback`, `errorCallback`): Object

Call this method to simulate a trigger button press. The method does not always immediately start a capture; instead it behaves like pressing a physical scan button.

##### Response

`string` with success message

##### Example

```js
barcodeManager.pressTrigger(
  (data) => { alert(data); },
  (err) => { alert(err);}
);
```

#### .releaseTrigger(`successCallback`, `errorCallback`): Object

Call this method to simulate a release of a trigger button. The method does not always immediately stop a capture; instead it behaves like releasing a physical scan button.

##### Response

`string` with success message

##### Example

```js
barcodeManager.releaseTrigger(
  (data) => { alert(data); },
  (err) => { alert(err);}
);
```

### autoScanTrigger

---

| Function | Description
|----------|------------
| [isAvailable](#isavailablesuccesscallback-errorcallback-object) | Determine if the auto scan feature is available on this device.

| [getCurrentRange](#getcurrentrangesuccesscallback-errorcallback-object) | Get the current range of the autoscan feature.
| [setCurrentRange](#setcurrentrangeid-successcallback-errorcallback-object) | Set the current range of the autoscan feature.

#### .isAvailable(`successCallback`, `errorCallback`): Object

Determine if the auto scan feature is available on this device.

##### Response

* `available` : `boolean` - indicates if autoscan is supported or not on this device.

```json
{ "available": true }
```

##### Example

```js
declare let autoScanTrigger : any;
isAvailable : boolean = false;
...
autoScanTrigger.isAvailable(
  (data) => {

);
```

#### .getSupportedRanges(`successCallback`, `errorCallback`): Object

Get the supported ranges of the autoscan feature.

##### Response

`supportedRanges` : `array` - provides array of ranges device supports. The array will be empty if device deos not support autoscan. Each object in the array contains:

* `id` : `integer` - unique value for a step in the supported ranges
* `name` : `string` - descriptive text related to the `id`

If AutoScan is not supported by device:

```json
{ "supportedRanges":[] }
```

If AutoScan is supported:

```json
{
  "supportedRanges":[
  {
    "id":0,
    "name":"Near"
  },
  {
    "id":1,
    "name":"Intermediate"
  },
  {
    "id":2,
    "name":"Far"
  }
  ]
}
```

##### Example

```js
declare let autoScanTrigger : any;
autoScanTrigger.getSupportedRanges(
  (data) => {
    alert(JSON.parse(data).supportedRanges);
    if(this.supportedRanges.length == 0)
      alert("Device does not support Auto Scan");
  },
  (err) => { alert(err); }
);
```

#### .getCurrentRange(`successCallback`, `errorCallback`): Object

Get the current range of the autoscan feature.

##### Response

`currentRange` : `object` - contains 2 fields:

* `id` : `integer`
* `name` : `string`

If AutoScan is not supported by device:

```json
{ "currentRange":null }
```

If AutoScan is supported:

```json
{
  "currentRange":
  {
      "id":1,
      "name":"Intermediate"
  }
}
```

##### Example

```js
declare let autoScanTrigger : any;
autoScanTrigger.getCurrentRange(
  (data) => {
    alert(JSON.parse(data).currentRange);
  },
  (err) => { alert(err); }
);
```

#### .setCurrentRange(`id`, `successCallback`, `errorCallback`): Object

Set the current range of the autoscan feature.

`id` : `integer` - should match one of the `id` values retrevied by the getSupportedRanges function.

##### Response

`string` with success message

##### Example

Set current range to "Intermediate"

```js
autoScanTrigger.setCurrentRange(
  0,
  (data) => { alert(data); },
  (err) => { alert(err); }
);
```
