    Study Notes

    Deploying Lightning Web Component Files

    • Learning objectives include configuring Lightning web component files, deploying files to an org, and verifying component behavior within an org environment.

    • Create a "bikeCard" component based on the prior Lightning component discussion without needing custom CSS.

    • Essential files for deployment:

      • bikeCard.html
      • bikeCard.js
      • bikeCard.js-meta.xml
    • Follow project structure under force-app/main/default/lwc/ for creating the component files.

    • Naming conventions:

      • Use camelCase for folder and file names in Lightning web components since hyphens are not permitted by Salesforce.
    • bikeCard.html defines the structure, displaying bike attributes such as Name, Description, and Price.

    • bikeCard.js contains the JavaScript logic:

      • Imports LightningElement
      • Initializes properties: name, description, category, material, price, and pictureUrl.
    • bikeCard.js-meta.xml serves as the component configuration file, providing necessary metadata:

      • Specifies apiVersion to bind the component to the appropriate Salesforce API version.
      • isExposed property (true/false) controls visibility in Lightning App Builder and Experience Builder.
    • Targets in the configuration file define where the component can be used within the Lightning App Builder, such as Application pages, Record pages, or Home pages.

    • Two main methods to display a Lightning web component:

      • Configure to support various flexipage types and add it through Lightning App Builder.
      • Create a tab that points to an Aura component containing the Lightning web component.

    Deploying Your Component

    • Authentication with the org is via the command palette in VS Code, using SFDX: Authorize an Org.

    • Deploy component files by selecting SFDX: Deploy This Source to Org in the correct folder.

    Handling Image Display

    • In order for images (hosted on Amazon AWS) to display in the app, add the URL to Trusted URLs:

      • API Name as ebikes.
      • URL set to https://s3-us-west-1.amazonaws.com.
    • Enable img-src for images and leave the Active checkbox selected.

    Creating a New Page for the Component

    • With the configuration file ready for use in Lightning App Builder, create a new app:

      • In Lightning App Builder, select App Page to begin.
    • Label the new app as "Bike Card" and define its layout.

    • Add the "Bike Card" component to the created page, adjusting its layout as needed, then save and activate it.

    • Access the new app through the App Launcher to verify functionality and visual representation of the component.

    • The unit concludes by stating upcoming lessons will include building an interactive component with event handling.
