Description​

A quick and easy way to display powerful demographics insights, increase user engagement, and improve overall website performance.

Installation​

Our SDK products are served from a single source.

The SDKs are designed to work with React and other declarative frameworks.

First, install the entry script with npm, yarn, or pnpm:

npm i --save @local-logic/sdks-js
yarn add @local-logic/sdks-js
pnpm add @local-logic/sdks-js

Example

import { useRef, useEffect } from "react";
import LLSDKsJS from "@local-logic/sdks-js";

const globalOptions = {
locale: "en", // If available, change to either english or french
appearance: {
  theme: "day",
  // Add any other appearance changes here
  variables: {
    "--ll-color-primary": "#fd3958",
    "--ll-color-primary-variant1": "#d5405b",
    "--ll-font-family": "Avenir, sans-serif"
  }
}
};

const localLogicClient = LLSDKsJS("your-api-key-here", globalOptions);

function LocalDemographicsSDKComponent() {
const containerRef = useRef(null);

useEffect(() => {
  if (!containerRef.current) {
    return;
  }

  const sdkOptions = {
    lat: 45.5282164, lng: -73.5978527

    // ...Other sdk specific options
  }

  const sdkInstance = localLogicClient.create(
    "local-demographics",
    containerRef.current,
    sdkOptions,
  );

  // It is important to destroy the SDK instance when the component is unmounted.
  return () => {
    sdkInstance.destroy();
  }
}, []);

return (
  <div
    ref={containerRef}
    style={{
      // Height is dependent on the SDK you are implementing
      height: "100%",
      width: "100%",
    }}
  />
);
}

export default LocalDemographicsSDKComponent;

Functions​

Once you initialize your SDK client with your API key and global options, several functions are available.

Create​

This function creates a new SDK widget based on the name specified.

sdkOptions are specific to each SDK being created.
