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
, andpictureUrl
.
- Imports
-
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.
- Specifies
-
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
.
- API Name as
-
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.
