Hello #Trailblazers,

In this blog post, we are going to talk how to create the rating component using Lightning Web Component

There are many use cases when we need to develop the rating component to display the rating for example survey result, interview feedback.

Step1 – Create Static Resource

Create a Static resource and name it fivestar and you can get the Static Resource. Five Star Rating

Step2 – Create a Lightning Web Component

Now, once you have create the Static resource, it’s time to Create the Rating Component.

1. Create a Lightning Web Component
2. use the code from the Given link
3. Link to Code

Usage

Call the component from the parent component like below

<div >
                <lightning-tile label="Salesforce" href="JavaScript:void(0);" type="media">
                    <c-five-star-rating value="5" onratingchange={handleRatingChanged} ></c-five-star-rating>
                </lightning-tile>    
            </div>

Code Explanation

1. value – In the code, you can see that I have passed one variable value which indicates what value you wanted to pass and the valid values are 1-5
2. onratingchange – this is the event raised by the rating component which in return sends the rating value from 1-5
3. readOnly – If you wanted your rating to be read-only then pass any value to this property like read-only=”yes”
4. handleRatingChanged(event){ let rating=event.detail.rating; }

Step3 – Create a feedback Component

1. Create a Lightning Web Component
2. use the code from the Given link
3. Link to Code
