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.
