Options

-o --open     Opens development server in default browser
-p --port     Port for development server
-m --mode     Enable alternative server UI modes
--webpack     Path to custom webpack.config.js

To see available options, run:

kit --help

All command line options can be set in your package.json file with a kit field.

{
  "kit": {
    "port": 9000,
    "open": true
  }
}

Modes

By default, the Kit dev server renders each component in isolation with minimal base styling for the document. Use the --mode flag to enable alternative modes for the development UI.

Library Mode

Renders components using the Kit Library component component, which displays all components together in a grid and in isolation when clicked.

File Types

Experimental

The Kit dev server includes experimental support for special .mdx and .jsx file types.

MDX

Example .mdx file

import { Box, Heading, Text } from './_scope'

# Markdown syntax works

<Box p={3} color='tomato'>
  <Heading fontSize={5}>
    {props.title}
  </Heading>
  <Text>
    Inline JSX syntax works as well
  </Text>
</Box>

JSX

The JSX format uses front matter to set default props for the rendered component. To provide components in scope, use the scope option in front-matter and include a JavaScript import statment.

Example .jsx file

---
title: Hello
scope: import scope from './_scope'
---
<Box p={3} color='tomato'>
  <Heading fontSize={5}>
    {props.title}
  </Heading>
</Box>
