# @w2a-iiot/parsers

Javascript parsers for WIKA's IIoT devices.
Can be used on the server or in the browser.

For more information about the parsers, please visit the [documentation](https://wika-group.github.io/javascript_parsers/).

## Installation

You can install the package using npm:

```bash
npm install @w2a-iiot/parsers
```

## Usage

```typescript
import { NETRIS2Parser, PEWParser } from '@w2a-iiot/parsers'

// creates a Netris2 parser instance
const parser = NETRIS2Parser()

// creates a PEW parser instance (supports uplink + downlink for TULIP2/TULIP3)
const pewParser = PEWParser()

// decodes the uplink message
const data = parser.decodeUplink({/** ... */})

// encodes a PEW downlink message
const downlink = pewParser.encodeDownlink({
  protocol: 'TULIP3',
  input: {
    action: 'getAlarmStatus',
    input: {
      processAlarmRequested: true,
      cmAlarmRequested: true,
    },
  },
})
```

## API Reference

The API provided by the parsers here differs from the prebuilt scripts in the way the encoding works.
While for LoRaWAN codec specification compatibility, only a single downlink can be returned, the parsers here can return multiple downlinks for a single input. They also optimize the downlinks to be as short as possible and merge multiple configuration changes into a single downlink where possible.
