app-watchdog
A package for controlling a Watchdog device from a JavaScript-based application. Relevant for Electron / WebView. For kiosks and exhibition centers, where there is a problem with the application freezing, and you need a quick solution.
Supported devices:
Supported OS (by serialport):
- Linux
- Windows
- OSX
Install:
yarn add app-watchdog
Example usage:
const WatchDog = require('app-watchdog');
const logger = (msg) => console.log(msg);
const wd = WatchDog(
{waitTime: 1},
{
messageInterval: 2000,
outputGet: (msg) => console.log('get message:', msg),
outputSent: (msg) => console.log('sent message:', msg),
outputLog: logger,
outputErr: logger,
onStart: () => console.log(msg)
},
).init()
wd.ALIVE(); // Send alive signal to Watchdog
wd.PAUSE(); // Pause wait timer
wd.RESUME(); // Resume wait timer
wd.LIGHT_ON(); // Turn on the indicator light
wd.LIGHT_OFF(); // Turn off the indicator light
wd.TEST_RESET();
wd.TEST_HARD_RESET();
wd.TEST_POWER_OFF();
wd.PARAMS_SET(9); // Set waitTime before reset to 9 minutes
wd.params; // Get watchdog parameters
wd.port; // Get port info
wd.paramsDefault; // Get default params
The main idea was to make this library "modular". To work with various USB Watchdog devices. To achieve this goal, I decided to use mixins.
As planned, you can safely add your modules for specific devices to this repository. Using this template. It is important to understand that the keys of the actionsList
object must remain unchanged. At least ALIVE, PARAMS_GET, PARAMS_SET.
Or, I need to add a plugin system. How do you think?
Any suggestions are greatly appreciated.
Attention! I have nothing to do with OpenDev. Use this at your own risk.
