About

This Web Component is a Web Component built from Lightning Wizard intended to use within a Lightning Web Component OSS Project.

It aims to provide a way to programatically build flows with Salesforce Flow styles and functionality, having full control of the wizard behavior in any scenario.

Features

Define wizard with Lightning Web components declaratively.
Override standard Navigation buttons definining specific step actions.
Customize flow using JavaScript function for step validation and post-processing.
Modify the flow steps using standard LWC templates.

Description

A lightning-wizard display a guided flow with multiple steps, only one is visible at a time. The progress is shown on the header along with a current step indicator.

Usage

As referenced on last LWC RFC, include the npm reference within your lwc.config.json or directly on your package.json.

At this moment, lightning-wizard does not work with native Shadow DOM. It requires Synthetic Shadow DOM. Import @lwc/synthetic-shadow before using the component.

package.json example

{
    "lwc": {
        "modules": [
            { 
                "npm": "lightning-wizard-oss" 
            }
        ]
    }
}

lwc.config.json example_

{
    "modules": [
        { 
            "npm": "lightning-wizard-oss" 
        }
    ]
}

Check the examples folder for implementation details.
