An open-source Notion UI built with Vue 3.

Try demo

We shared about Lotion and recreating the Notion UI during CityJS Singapore's pre-conference meetup on 27th July!

• Block-based editor
• Drag to reorder blocks
• Basic Markdown-parsing including bold, italic, headings and divider
• Type '/' for command menu and shortcuts
• Register your own blocks
• Read-only mode

1. Install package

npm i @dashibase/lotion

2. Basic Lotion editor

The following Vue component will initialize a basic Lotion editor.

<template>
  <Lotion :page="page" />
</template>
<script setup lang="ts">
import { ref } from 'vue'
import { v4 as uuidv4 } from 'uuid'
import { Lotion, registerBlock } from '@dashibase/lotion'

const page = ref({
  name: '🧴 Lotion',
  blocks:[{
    id: uuidv4(),
    type: 'TEXT',
    details: {
      value: 'Hello, World!'
    },
  }],
})
</script>

3. Create custom components

See examples/CustomBlock.vue for an example of a custom block.

The custom block component can accept the following props:

• block: A Block object. See src/utils/types.ts for details.
• readonly: A boolean, which sets whether the block/editor is in read-only mode.

The custom block component can also optionally expose the following methods (remember to call defineExpose):

• onSet: This is triggered when a user converts any block into this blocktype. It is called before the blocktype is changed.
• onUnset: This is triggered when a user converts this block into any blocktype. It is called before the blocktype is changed.

<template>
  <div>
    🧴
  </div>
</template>
<script setup lang="ts">
import { PropType } from 'vue'
import { types } from '../src'

const props = defineProps({
  block: {
    type: Object as PropType<types.Block>,
    required: true,
  },
  readonly: {
    type: Boolean,
    default: false,
  },
})

function onSet () {
  alert('Moisturizing...')
}

function onUnset () {
  alert('Moisturized!')
}

defineExpose({
  onSet,
  onUnset,
})
</script>

4. Register custom components

See examples/Example.vue for an example of registering a custom block.

After creating the custom component, register it as follows:

import CustomBlock from './CustomBlock.vue'
import { addIcons } from "oh-vue-icons"
import { FaPumpSoap } from "oh-vue-icons/icons"
import { registerBlock } from '@dashibase/lotion'

// Add the icon (from oh-vue-icons.js.org/)
addIcons(FaPumpSoap)
// Register the block
// registerBlock('<BLOCK_TYPE_ID>', '<BLOCK_TYPE_LABEL>', <BLOCK_COMPONENT>, 'BLOCK_ICON')
registerBlock('LOTION', 'Moisturize', CustomBlock, 'fa-pump-soap')
</script>

After that, you should be able to see the custom block when the user opens the menu to switch to different blocks.

1. Clone this repository, go to the root directory and install packages

git clone https://github.com/dashibase/lotion
cd lotion
npm i

2. Run dev

npm run dev

If you head to http://localhost:5173 on your browser, you should see what looks like the screenshot above.

3. Contribute!

Lotion is quite limited for now but we hope it serves as a good starting point for other folks looking to build their own editors.

We would love to make Lotion more extensible and welcome any suggestions or contributions!

See CONTRIBUTING.md for details.
