⚠️ Publishing of the package has been paused. Salesforce employees should use the internal package.

Base Lightning web components are the building blocks of the modern user interfaces for Lightning Experience, the Salesforce app, and Lightning Communities. The components incorporate Lightning Design System markup and classes, providing improved performance and accessibility with a minimum footprint.

The lightning namespace components are optimized for common use cases. They handle accessibility, real-time interaction, and enhanced error messages.

// with npm
npm install lightning-base-components

// with yarn

export default class FooApp extends LightningElement {
    clickedButtonLabel;

    }
}

app.html

<template>
    <div class="slds-m-top_small slds-m-bottom_medium">
        <h2 class="slds-text-heading_small slds-m-bottom_small">

Some components in the npm package are not yet supported for use by customers on the Salesforce platform. For example:

  • lightning-context
  • lightning-dialog
  • lightning-grouped-combobox
  • lightning-message-dispatcher
  • lightning-picklist
  • lightning-popup
  • lightning-select
  • lightning-stacked-tab
  • lightning-stacked-tabset

We are not currently accepting feature or bug fix requests for components that work only outside the Salesforce platform. Use these components in your projects outside the Salesforce platform at your own risk. Note that this is not an exhaustive list.

To see if a component can work only outside the Salesforce platform, check the .js-meta.xml config file in the component directory. For example, lightning-dialog is not supported on the Salesforce platform, and dialog.js-meta.xml includes only the following tag:

<isExposed>true</isExposed>

Contrastingly, a component that's supported outside and on the Salesforce platform includes the isExposed, minApiVersion, and support tags. Components supported on the Salesforce platform are listed in the Component Library.

What's Not Included

Some base components can run only on the Salesforce platform because they rely on Salesforce data to properly function. These components aren’t included in the package.

  • lightning-input-rich-text
  • lightning-file-upload
  • lightning-record-edit-form
  • lightning-record-view-form
  • lightning-record-form
  • lightning-input-field
  • lightning-output-field
  • lightning-map

Usage

The npm package content is used by https://webcomponents.dev/org/lwc. This site exposes components in the "What's Included" list. If you're a Salesforce customer, note that only components listed in the Component Library are supported in Salesforce orgs, which also include components that are not available in this npm package.
