lit-html

Adds syntax highlighting and language support for html inside of JavaScript and TypeScript tagged template strings, such as used in lit-html and other frameworks.

Features

• Syntax highlighting of inline html blocks.
• IntelliSense for html tags and attributes.
• Quick info hovers on tags.
• Formatting support.
• Auto closing tags.
• Folding html.
• CSS completions in style blocks.
• Works with literal html strings that contain placeholders.

Usage

The lit-html extension adds highlighting and IntelliSense for lit-html template strings in JavaScript and TypeScript. It works out of the box when you use VS Code's built-in version of TypeScript.

If you are using VS Code 1.30 or older and are using a workspace version of typescript, you must currently configure the TS Server plugin manually by following these instructions

Configuration

You can either configure this plugin using a tsconfig or jsconfig as described here, or configure the plugin using VS Code. This requires VS Code 1.30+ and TS 3.2+. Note the VS Code based configuration override the tsconfig or jsconfig configuration.

Tags

This extension adds html IntelliSense to any template literal tagged with html or raw:

import {html} from 'lit-html'

const a = html`
    <div></div>
`

You can enable IntelliSense for other tag names by settings "lit-html.tags":

"lit-html.tags": [
    "html",
    "template"
]

Formatting

The plugin formats html code by default. You can disable this by setting "lit-html.format.enabled": false:

"lit-html.format.enabled": false
