LWC Example

Overview​

This example demonstrates the implementation of the Plinqx FlowService wrapper in a Lightning Web Component (LWC). The example focuses on a practical application where the LWC component interacts with an external address search service via a Plinqx flow.

Scenario​

The LWC component in this example is designed to perform a dynamic address search. It leverages a Plinqx flow that makes a callout to an external mock address service, retrieves a list of addresses matching the search criteria, and displays the results in the component.

Note: The address service used here is a mock service for demonstration purposes. It returns random results without applying any specific search logic.

LWC Component Functionality​

  • The LWC component is triggered by an onchange event.

  • Upon triggering, it calls the Plinqx service flow, which then makes an external callout and returns the service responses.

Code Implementation​

import { LightningElement, track } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import callFlowWithResponse from '@salesforce/apex/Plinqx.FlowService.callFlowWithResponse';

const flowApiName = 'FlowService_Example';

export default class LwcServiceWrapperDemo extends LightningElement {
  @track results = [];

  handleSearchAddress(event) {
    this.results = [];
    let objParams =
      //the flow input paramaters as an object
      {
        searchParam: event.detail.value, //set the input parameter of the flow
      };
    callFlowWithResponse({
      flowNameSpace: '', //The flow namespace if from package i.e. Plinqx
      flowAPIName: flowApiName, //The flow API Name
      flowParams: objParams, //The flow input paramaters
      flowResponseVariable: 'addressResponse', //The output paratemeter of your flow to retrieve
    })
      .then((result) => {
        this.results = result;
      })
      .catch((error) => {
        this.handleNotification('Address Search', error.message, 'error');
      });
  }

  handleResultClick(event) {
    //implement result click logic here
  }

  handleNotification(title, message, variant, mode) {
    this.dispatchEvent(
      new ShowToastEvent({
        title,
        message,
        variant,
        mode,
      })
    );
  }
}

Other Configuration​

Setting Up Named Credential:

This named credential setup is crucial for securely calling the external mock address service from the Plinqx flow.

Package Installation​

For practical demonstration, an unmanaged package of this LWC example is available. Use the links below to install it in your Salesforce environment:

Sample Response​

Below is an example of the response returned by the demo address service. Note that results will vary with each search, reflecting the mock nature of the service.
