Lightning Web Components (LWC) is an enterprise-grade web components foundation for building user interfaces. LWC provides a simple authoring format for UI components, which is compiled into low-level Web Component APIs. The lwc
package is the main entry point for dependencies.
@lwc/synthetic-shadow
package as an optional polyfill for older browsers.Developing a Lightning web component is this easy:
counter
├──counter.css
├──counter.html
└──counter.js
<!-- counter.html -->
<template>
<p>Counter: {count}</p>
<button onclick="{increaseCounter}">Add</button>
</template>
/* counter.css */
p {
font-family: serif;
font-size: large;
}
// counter.js
import { LightningElement } from 'lwc';
export default class Counter extends LightningElement {
count = 0;
increaseCounter() {
this.count += 1;
}
}
LWC supports all browsers supported in Salesforce Lightning Experience.
As of LWC v3.0.0, Microsoft® Internet Explorer® 11 is no longer supported.
lwc.dev has all the information you need to develop components using LWC, including code recipes and code playgrounds.
For support, use the lwc
tag on Stack Overflow or the lightning-web-components
tag on Salesforce Stack Exchange.
When filing a bug, it's useful to use playground.lwc.dev to create a live reproduction of the issue.
Changes are documented at github.com/salesforce/lwc/releases.
lwc
packageThis package (lwc
) is a convenience package that re-exports all packages that might be used for LWC component development. Installing it also installs the core @lwc/*
packages.
For example, to use @lwc/engine-server
from this package, you can do:
import { renderComponent } from 'lwc/engine-server';
This is equivalent to:
import { renderComponent } from '@lwc/engine-server';
The @lwc/ssr-compiler
and @lwc/ssr-runtime
packages are still considered experimental, and may break without notice.
