JavaScript / TypeScript Library

This example code allows you to perform database operations with the PxServ project. The following operations are supported:

• Save data to the database

• Toggle data between 0 and 1 in the database

• Read data from the database

• Delete data from the database

Requirements

Before using this example, ensure the following libraries are installed:

• pxserv: Used to communicate with the PxServ API.

Installation

You can install the PxServ library using npm:

npm install pxserv

Connection Settings

Enter your PxServ API key and optionally the base URL in the following fields:

JavaScript

// Include the PxServ library in the project
const PxServ = require("pxserv").default;

// Create a new PxServ Instance by entering your API key
const pxServ = new PxServ({
  apiKey: "API_KEY", // Write your own API key here
});

// Representative data
const temp = "24.3°C"; // Environment temperature
const hum = "58%"; // Humidity
const light = "1"; // Lighting on (1 = on, 0 = off)

(async () => {
  try {
    // Saving data
    await pxServ.setData("temp", temp);
    await pxServ.setData("hum", hum);
    await pxServ.setData("light", light);
    console.log(
      "Temperature, humidity and lighting conditions were recorded in PxServ."
    );

    // Get data
    const currentTemp = await pxServ.getData("temp");
    const currentHum = await pxServ.getData("hum");
    const currentLight = await pxServ.getData("light");

    console.log(`Temperature: ${currentTemp}`);
    console.log(`Humidity: ${currentHum}`);
    console.log(`Light: ${currentLight === "1" ? "On" : "Off"}`);

    // Toggle data
    await pxServ.toggleData("light");
    console.log("Lighting status has been changed.");
    const toggledLight = await pxServ.getData("light");
    console.log(`New lighting status: ${toggledLight === "1" ? "On" : "Off"}`);

    // Get all data
    const allData = await pxServ.getAll();
    console.log("All Data:");
    console.log(allData);

    // Remove data
    await pxServ.removeData("temp");
    await pxServ.removeData("hum");
    await pxServ.removeData("light");
    console.log("Test data has been successfully removed.");
  } catch (error) {
    console.error("An error has occurred:", error);
  }
})();

TypeScript

import PxServ from "pxserv";

// Create a new PxServ Instance by entering your API key
const pxServ = new PxServ({
  apiKey: "API_KEY", // Write your own API key here
});

// Representative data
const temp = "24.3°C"; // Environment temperature
const hum = "58%"; // Humidity
const light = "1"; // Lighting on (1 = on, 0 = off)

(async () => {
  try {
    // Saving data
    await pxServ.setData("temp", temp);
    await pxServ.setData("hum", hum);
    await pxServ.setData("light", light);
    console.log(
      "Temperature, humidity and lighting conditions were recorded in PxServ."
    );

    // Get data
    const currentTemp = await pxServ.getData("temp");
    const currentHum = await pxServ.getData("hum");
    const currentLight = await pxServ.getData("light");

    console.log(`Temperature: ${currentTemp}`);
    console.log(`Humidity: ${currentHum}`);
    console.log(`Light: ${currentLight === "1" ? "On" : "Off"}`);

    // Toggle data
    await pxServ.toggleData("light");
    console.log("Lighting status has been changed.");
    const toggledLight = await pxServ.getData("light");
    console.log(`New lighting status: ${toggledLight === "1" ? "On" : "Off"}`);

    // Get all data
    const allData = await pxServ.getAll();
    console.log("All Data:");
    console.log(allData);

    // Remove data
    await pxServ.removeData("temp");
    await pxServ.removeData("hum");
    await pxServ.removeData("light");
    console.log("Test data has been successfully removed.");
  } catch (error) {
    console.error("An error has occurred:", error);
  }
})();

Usage

Add this code to your project and run it after installing the required libraries. The code will perform data addition, reading, and deletion operations with the PxServ API.

Sample Outputs

Below are example outputs you may see in the console:

Temperature, humidity and lighting conditions were recorded in PxServ.
Temperature: 24.3°C
Humidity: 58%
Light: On
Lighting status has been changed.
New lighting status: Off
All Data:
{
  temp: {
    lastUpdate: '2025-04-06T09:08:59.570Z',
    icon: 'defaultIcon',
    value: '24.3°C'
  },
  hum: {
    lastUpdate: '2025-04-06T09:08:59.649Z',
    icon: 'defaultIcon',
    value: '58%'
  },
  light: {
    lastUpdate: '2025-04-06T09:08:59.997Z',
    icon: 'defaultIcon',
    value: '0'
  }
}
Test data has been successfully removed.

These outputs indicate that the data has been successfully added, read, and deleted.
