NeighborhoodMatch displays a list of similar neighborhoods.

For more details on the similarity score and how neighborhoods are calculated, see the "Calculating Neighborhood Similarity" of the Similar Neighborhoods API endpoint documentation.


The affordability index (price comparison tag) is only available in the US.


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


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-border-radius-small": "8px",
"--ll-border-radius-medium": "16px",
"--ll-font-family": "Avenir, sans-serif"

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

function NeighborhoodMatchSDKC#omponent() {
const containerRef = useRef(null);

useEffect(() => {
if (!containerRef.current) {

const sdkOptions = {
// Set the lat and lng of the location
lat: 45.5282164,
lng: -73.5978527,

// ...Other sdk specific options

const sdkInstance = localLogicClient.create(

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

return (
// Height is dependent on the SDK you are implementing
height: "100%",
width: "100%",

export default NeighborhoodMatchSDKC#omponent;



Your API Key will be provided to you by the LocalLogic team.


As part of the NeighborhoodMatch SDK, you have the option to customize the implementation in three ways:

  1. Restrict the returned similar neighborhoods to only neighborhoods relevant to you.

    This is important because it allows you to keep the homeseeker in your funnel by not recommending neighborhoods outside of your territory or where you do not have a page. By default, when no configuration is provided “all” similar nearby neighborhoods are returned; the only filtering applied is to limit to other similar neighborhoods within the metropolitan statistical area (MSA) or within 100 kms, if the neighborhood is not within an MSA.

  2. Customize the images displayed for each neighborhood.

    This allows you to avoid prescribed images. By default, no images will be shown for neighborhoods without configured images.

  3. Assign each similar neighborhood card to a link.

    The vision here is that similar neighborhoods can be used to “shop” between neighborhoods by directly linking neighborhood pages (either NeighborhoodWrap implementations or even as an addition to non-NeighborhoodWrap neighborhood pages). The goal of recommending similar neighborhoods is to allow a user to click through and learn about the neighborhood and view homes in the area. For this to work, links must be assigned for when a user clicks on each card. By default, no link is added to cards without a link configured: they can be viewed but not clicked.

For the NeighborhoodMatch SDK, a configuration file is leveraged to customize the list of neighborhoods used and displayed to the user, to ensure they link within the implementing site’s available pages, and to customize the images displayed for each neighborhood.


When no configuration file is provided, no images will be shown for each neighborhood, the list of similar neighborhoods will not be filtered, and the cards in the SDK will not display as links. However, the SDK can still be implemented without the configuration being applied and it will be updated to match the given neighborhood once the configuration file is applied.

Generating a NeighborhoodMatch Configuration File

  1. Prepare a CSV file that contains the fields outlined below.
  2. Send the CSV to Local Logic via a support ticket. The team at Local Logic will help convert the neighborhoods to supported geog_id’s and apply the configuration the next business day.
CSV Information
Example configuration file - geog_id
Example configuration file - neighborhood name
geog_id OR neighborhoodtruegeog_id is the specific Local Logic external ID for the neighborhood, if available and known. neighborhood is the name of the neighborhood for identifying and matching to our Local Logic list of neighborhoods.
thumbnail_urltrueThe full URL for the image representing the neighborhood when it appears in configured NeighborhoodMatch SDKs.
redirect_urltrueThe full URL that should be the source link if a user clicks on the neighborhood. It should be a URL on your site that exists (or will exist) for each neighborhood.

The "neighborhood" option can be used if the Local Logic geog_id is unknown for the desired neighborhood. In this case, be as descriptive as possible: “Little Italy, San Diego, CA” is better than “Little Italy,” as there are at least 8 Little Italies in the United States.


For the "thumbnail_url", the server where the image thumbnail URL is hosted needs at a minimum to have the following addresses added as allowed origins to the CORS header:

  • Required for the SDK implementation:

  • Highly recommended for support, testing, and debugging: http://localhost:3000 http://localhost:3001

The thumbnail image could also be publicly accessible (if CORS headers are not used).

It’s recommended that your thumbnail image(s) be at minimum 144 px by 400 px and at maximum 500 px by 800 px for best results in the SDK.

Global options

const localLogicClient = localLogicSDK(apiKey, globalOptions)

These options are available accross SDKs. You will also be able to specify SDK specific options depending on the SDK you are implementing. These options will be available in the SDK specific documentation

apiKeytruestringApiKey required for making requests to the Local Logic API.
globalOptions.appearancefalseAppearanceThe appearance option provides theme and variable support customizing the look and feel of your widgets.
globalOptions.localefalse"en" or "fr""en"The locale option specifies the language of the scores and the UI interface.


Local Logic SDKs support visual customization using the Appearance API, which allows you to match the look of the SDK to your brand.

type Appearance = {
theme?: "day" | "night"; // Defaults to "day"
variables?: {
[key: string]: string;

Commonly used variables

--ll-color-primaryThe primary brand color.
--ll-color-primary-variant1A slightly darker version of the primary brand colour. This variable should always be changed in conjunction with --ll-color-primary.
--ll-font-familyChanges the font family used throughout the SDKs. Currently, the SDKs only support system fonts. This value should always include a fallback font family, ex. Inter, sans-serif.
--ll-font-size-baseUsed to scale the font size up or down.
--ll-spacing-base-unitUsed to scale the overall padding of the SDKs.


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


const sdkInstance = localLogicClient.create("neighborhood-match", container, sdkOptions)

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

sdkOptions are specific to each SDK being created.

sdkTypetruestringThe SDK you would like to create. "neighborhood-match" in this case.
containertrueHTMLElementThe element to render in to.
sdkOptionstrueSDKOptionsOptions required for te specified sdkType. Options are detailed below.


sdkOptions.geographyId*stringThe Local Logic geography ID. This is the preferred instantiation method.

* This field is required if you are not using lat/lng.*numberInitial viewport latitude.

* This field is required if you are not using geographyId. If geographyId is defined, this field is ignored.
sdkOptions.lng*numberInitial viewport longitude.

* This field is required if you are not using geographyId. If geographyId is defined, this field is ignored.
sdkOptions.titlefalseboolean | stringTitle is enabled by default and is provided as a translated string. You have the ability to remove the title or supply your own title string.
sdkOptions.hideAffordabilityTagsfalsebooleanfalseSpecifies whether or not the affordability comparison tag on each neighborhood card should be hidden.



This function is used to update the widget with new values. This can be useful when, for example, you want to change the widget location.

The sdkOptions object follows the same structure as on creation.


sdkInstance.on(event, callback)

This function takes a callback which is triggered when an event occurs. Currently, there is only one event.

eventtrue"change"The name of the event.
callbacktrueCallbackFunctionThe callback to be triggered when the specified event occurs.
type CallbackFunction = ({ type: string, data: unknown }) => void;



This function is used to teardown the created SDK widget.

Supporting API Endpoints

The following Local Logic APIs are used by the SDK to display data.

Similar NeighborhoodsUsed to retrieve the configured client-specific neighborhoods with the highest similarity to the given neighborhood.
