Surround the property with curly braces: {property} because this is the syntax for data binding in a Lightning web component template. Data binding is a way to link a property in a component's template to a property in the component's JavaScript class.When the value of the property changes, the component re-renders and updates the template accordingly1. For example, suppose there is a component that has a name property in its JavaScript class:

// helloWorld.js import { LightningElement, api } from 'lwc';

export default class HelloWorld extends LightningElement { // Declare a public name property @api name = 'World'; }

To render the name property in the component's template, surround it with curly braces:

<!-- helloWorld.html --> <template>

Hello, {name}! </template>

The output will look like this:

Hello, World!

The fastest route to setting up a B2B Commerce Store as a developer is to use sfdx setup scripts.Sfdx is a command-line tool that allows developers to create, manage, and deploy Salesforce applications using source-driven development2.Sfdx setup scripts are preconfigured commands that automate the process of creating and configuring a B2B Commerce Store in a scratch org3.A scratch org is a temporary Salesforce org that can be used for development and testing purposes4. Using sfdx setup scripts, a developer can quickly set up a B2B Commerce Store with sample data and customizations, without having to manually create a store in the Commerce app or import a previously exported store archive.The developer can also use sfdx commands to push and pull source code changes between the scratch org and the local project folder5.To use sfdx setup scripts, the developer needs to install Salesforce CLI, Visual Studio Code, and Git on their machine, and clone the B2B Commerce on Lightning Experience repository from GitHub6.Then, the developer can run the setup scripts from the command line or from Visual Studio Code7.Reference:Salesforce CLI,SFDX Setup Scripts,Scratch Orgs,Source-Driven Development,Set Up Your Development Environment,Create Your First Store

Adjust next-state in previous subflow configuration because this is the way to bring in a checkout flow step to another sequence order. A checkout flow step is a subflow that represents a stage in the checkout process, such as shipping, payment, or review.A subflow is a reusable unit of logic that can be invoked from another flow1. To change the order of the checkout flow steps, a developer needs to modify the next-state attribute of the previous subflow configuration.The next-state attribute specifies the name of the next subflow to execute after the current one finishes2. For example, suppose there are three checkout flow steps: shipping, payment, and review. To bring in the payment step before the shipping step, the developer needs to adjust the next-state attribute of the start subflow configuration to point to the payment subflow instead of the shipping subflow:

<!-- start.subflow --> <subflow name=''start''> <subflow-state id=''start'' subflow=''start''> <next-state on=''success'' value=''payment''/> <!-- Change this from shipping to payment --> </subflow-state> </subflow>

The fastest route to establishing the data needed for checkout development when setting up a new store is to use sfdx setup scripts.Sfdx is a command-line tool that allows developers to create, manage, and deploy Salesforce applications using source-driven development3.Sfdx setup scripts are preconfigured commands that automate the process of creating and configuring a B2B Commerce Store in a scratch org4.A scratch org is a temporary Salesforce org that can be used for development and testing purposes5. Using sfdx setup scripts, a developer can quickly set up a B2B Commerce Store with sample data and customizations, without having to manually create a store in the Commerce app or import a previously exported store archive.The developer can also use sfdx commands to push and pull source code changes between the scratch org and the local project folder6.To use sfdx setup scripts, the developer needs to install Salesforce CLI, Visual Studio Code, and Git on their machine, and clone the B2B Commerce on Lightning Experience repository from GitHub7.Then, the developer can run the setup scripts from the command line or from Visual Studio Code8.Reference:Salesforce CLI,SFDX Setup Scripts,Scratch Orgs,Source-Driven Development,Set Up Your Development Environment,Create Your First Store

To introduce new screen behavior in a checkout flow step, the developer should clone the appropriate subflow and replace the Lightning web components in it. This way, the developer can customize the layout, logic, and functionality of the checkout step without modifying the default subflow. The developer can also use the component visibility feature in screen flows to show or hide components based on conditions.Reference:

To update the checkout process with different payment types, the developer should create a custom Lightning web component for the checkout flow that has all the options available. Within that component, the developer can pull data from the account to determine which options to show based on the custom checkbox field. This approach allows the developer to have full control over the payment logic and UI, and avoid using multiple components or events.Reference:

Commerce Diagnostics Event Logging is a tool that allows developers to view and analyze the events that occur during the execution of a Commerce request. It can help identify errors, performance issues, and potential optimizations in the code.Commerce Diagnostics Event Logging can be enabled or disabled in the Commerce Settings page in Setup1.Reference:1: Configure Your B2B and B2B2C Commerce Store - Trailhead2

To fire a custom event from a Lightning web component and propagate it up to the DOM, the event must have the bubbles and composed properties set to true. The bubbles property indicates whether the event should bubble up through the component hierarchy or not. The composed property indicates whether the event should cross the shadow boundary and reach the DOM.If either of these properties is false, the event will not be visible to the DOM elements3.Reference:3: Communicate with Events - Trailhead4

To establish communication between components that are not in the same DOM tree, the developer should use the publish-subscribe pattern. This pattern allows components to communicate across the DOM tree without depending on their position in the hierarchy. The developer can use the Lightning Message Service (LMS) to implement this pattern, which provides a standard and secure way to exchange messages across different components and namespaces.Reference:
