Setting Up Your Salesforce DX Environment and Creating Your First Lightning Web Component

-

What is Salesforce DX?

Salesforce DX (Developer Experience) is a powerful development environment that allows for better source-driven development and collaboration. A Salesforce DX project features a specific structure and a configuration file that designates the directory as a Salesforce DX project. The "DX" stands for Data Transfer, indicating the project's focus on efficiently managing and transferring data.

Salesforce DX introduces a new project structure for your organization’s metadata (including code and configuration), templates, sample data, and tests. By utilizing a version control system (VCS), teams can ensure consistency throughout the development process.

Setting Up Salesforce DX for the First Time

Prerequisites

Before you begin, ensure you have the following items installed:

  • Salesforce CLI
  • Visual Studio Code (along with necessary extensions)

Step 1: Install Salesforce CLI

Download the Salesforce CLI executable files from the following links:

Step 2: Install the CLI

  1. Install the downloaded executable file on your machine.
  2. Open the Command Prompt.

Step 3: Verify CLI Installation

Navigate to the bin folder of Salesforce CLI and type the following command:

sfdx --version

If you see the version details, it means the CLI is working fine.

Step 4: Set Up Visual Studio Code

Download and install Visual Studio Code.

Step 5: Install Salesforce Extensions

  1. Launch Visual Studio Code.
  2. Click on the Extensions icon in the sidebar.
  3. Search for Salesforce Extension Pack and install it.

Step 6: Verify Environment Readiness

  1. Press Ctrl + Shift + P to open the Command Palette.
  2. Type SFDX to access Salesforce DX commands.

Step 7: Create a New Project

  1. Select SFDX: Create Project.
  2. Enter a project name, such as LWC_Project.
  3. Choose a folder where you want to store your code.

Step 8: Authorize Your Org

  1. Press Ctrl + Shift + P again and type SFDX: Authorize an Org.
  2. Enter the login URL (e.g., login.salesforce.com or test.salesforce.com).
  3. After successful login, you will see a "Success" status in Visual Studio Code.

Step 9: Create Your First Lightning Web Component

  1. Press Ctrl + Shift + P and type SFDX: Create Lightning Web Component.
  2. Name your component FirstWebComponent and select force-app/main/default/lwc.

Step 10: Add HTML Code

In the firstWebComponent.html file, enter the following code:


<template>
    <lightning-card title="FirstWebComponent" icon-name="custom:custom12">
        <div class="slds-m-around_medium">
            <p>This is my First Web Component Page, {welcomeNotes}!</p>
            <lightning-input label="Name" value={welcomeNotes} onchange={onChangeHandler}></lightning-input>
        </div>      
    </lightning-card> 
</template>

Step 11: Add JavaScript Code

In the firstWebComponent.js file, enter the following code:


import { LightningElement, track } from 'lwc';

export default class FirstWebComponent extends LightningElement {
    @track welcomeNotes = 'Welcome to my page';

    onChangeHandler(event) {
        this.welcomeNotes = event.target.value;
    }
}

Step 12: Add Metadata Configuration

In the firstWebComponent.js-meta.xml file, add the following code:


<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata">
    <apiVersion>50.0</apiVersion>
    <isExposed>true</isExposed>
    <targets>
        <target>lightning__AppPage</target>
        <target>lightning__RecordPage</target>
        <target>lightning__HomePage</target>
    </targets>
</LightningComponentBundle>

Step 13: Deploy Your Code

  1. Press Ctrl + Shift + P and enter SFDX: Deploy Source to Org.
  2. Once deployment is successful, you will receive a success status in Visual Studio Code.

Conclusion

Now, your Lightning Web Component will be available in the Lightning App Builder, ready for use in your Salesforce environment. With Salesforce DX, you can streamline your development process, making it more efficient and organized.

Thank you for following along!

Best Practices for Creating Salesforce Roll-Up Summary Triggers

-
Understanding the Use of Roll-Up Summary Fields in Salesforce Roll-up summary fields are a powerful feature in Salesforce that allow you to automatically display calculated values on a master record based on the related detail records. These detail records must be linked directly to the master record through a master-detail relationship. With roll-up summary fields, you can perform various calculations, such as totals, counts, and averages, making it easier to track important metrics related to your data. Why Use Roll-Up Summary Fields? Roll-up summary fields provide several benefits: Automated Calculations: They automatically update whenever related detail records are created, updated, or deleted, ensuring your master record reflects the most current data. Data Integrity: By consolidating information from related records, roll-up summary fields help maintain data integrity and accuracy within your Salesforce org. Improved Reporting: They enhance your reporting capabilities by summa...

CREATE WEB-FORM USING LIGHTNING WEB COMPONENTS SALESFORCE

What is a Web Form? A web form (also called an HTML form) allows users to input data that is sent to a server for processing. These forms are commonly used for various tasks, such as submitting shipping or credit card information for orders, or querying search engines. They can include elements like checkboxes, radio buttons, or text fields, resembling paper or database forms. Example of a Web Form In this example, we will create a web form using  Lightning Web Components (LWC)  in Salesforce to submit data to an object. Step 1: Your HTML Page ( webform.html ) This HTML page contains the structure of the form. We will use the  lightning-record-form  component to automatically generate a form based on the fields of an object. html < template > < lightning-messages > </ lightning-messages > < lightning-record-form object-api-name = {accountObject} fields = {myFields} onsuccess = {handleAccountCreated} > </ li...

Long-Running Callouts with Multiple Apex Continuations

-
Image
Salesforce provides the Continuation class in Apex to handle long-running requests to external web services without hitting the limits imposed on synchronous requests. Traditionally, Salesforce only supported Continuations from Visualforce pages , but since the Summer '19 release , both Aura and Lightning Web Components (LWC) can also invoke Apex Continuation methods. This functionality allows handling multiple asynchronous callouts, which no longer count against the 10 synchronous callout limit that exceeds five seconds. What is a Continuation? A Continuation is a pattern where an Apex method makes a request to an external service but does not wait for the response immediately. The request "forgets" about the response and allows Salesforce to process it asynchronously. Once the response is received, a callback method is invoked to handle the data. Example: Making Multiple Callouts with Apex Continuation Below is an example that demonstrates how to send multiple long-...
