puck
The self-hosted, drag and drop editor for React.
Features
- 🖱️ Drag and drop: Visual editing for your existing React component library
- 🌐 Integrations: Load your content from a 3rd party headless CMS
- ✍️ Inline editing: Author content directly via puck for convenience
- ⭐️ No vendor lock-in: Self-host or integrate with your existing application
Example
Render the editor:
// Editor.jsx
import { Puck } from "@measured/puck";
import "@measured/puck/dist/index.css";
// Create puck component config
const config = {
components: {
HeadingBlock: {
fields: {
children: {
type: "text",
},
},
render: ({ children }) => {
return <h1>{children}</h1>;
},
},
},
};
// Describe the initial data
const initialData = {
content: [],
root: {},
};
// Save the data to your database
const save = (data) => {};
// Render Puck editor
export function Editor() {
return <Puck config={config} data={initialData} onPublish={save} />;
}
Render the page:
// Page.jsx
import { Render } from "@measured/puck";
import "@measured/puck/dist/index.css";
export function Page() {
return <Render config={config} data={data} />;
}
Installation
Install the package
npm i @measured/puck --save
Or generate a puck application using a recipe
npx create-puck-app my-app
Recipes
Puck is a React component that can be easily integrated into your existing application. We also provide helpful recipes for common use cases:
- next: Next.js app example
Plugins
Puck can be configured to work with plugins. Plugins can extend the functionality to support novel functionality.
Official plugins
heading-analyzer
: Analyze the heading outline of your page and be warned when you're not respecting WCAG 2 accessibility standards.
Developing a plugin
The plugin API follows a React paradigm. Each plugin passed to the Puck editor can provide three functions:
renderRoot
(Component
): Render the root node of the preview contentrenderRootFields
(Component
): Render the root fieldsrenderFields
(Component
): Render the fields for the currently selected componentrenderComponentList
(Component
): Render the component list
Each render function receives three props:
- children (
ReactNode
): The normal contents of the root or field. You must render this if provided. - state (
AppState
): The current application state, including data and UI state - dispatch (
(action: PuckAction) => void
): The Puck dispatcher, used for making data changes or updating the UI. See the action definitions for a full reference of available mutations.
Example
Here's an example plugin that creates a button to toggle the left side-bar:
const myPlugin = {
renderRootFields: ({ children, dispatch, state }) => (
<div>
{children}
<button
onClick={() => {
dispatch({
type: "setUi",
ui: { leftSideBarVisible: !state.ui.leftSideBarVisible },
});
}}
>
Toggle side-bar
</button>
</div>
),
};
Custom fields
Puck supports custom fields using the custom
field type and render
method.
In this example, we optionally add the <FieldLabel>
component to add a label:
import { FieldLabel } from "@measured/puck";
export const MyComponent: ComponentConfig = {
fields: {
myField: {
type: "custom",
render: ({ field, name, onChange, value }) => {
return (
<FieldLabel label={field.label || name}>
<input
placeholder="Enter text..."
type="text"
name={name}
defaultValue={value}
onChange={(e) => onChange(e.currentTarget.value)}
></input>
</FieldLabel>
);
},
},
},
};
DropZones
Puck supports creating complex layouts (like multi-column layouts) using the <DropZone>
component.
Example
In this example, we use the <DropZone>
component to render two nested DropZones within another component:
import { DropZone } from "@measured/puck";
export const MyComponent: ComponentConfig = {
render: () => {
return (
<div>
<DropZone zone="first-drop-zone">
<DropZone zone="second-drop-zone">
</div>
)
}
};
Custom root entry points
You can also do this at the root of your component. This is useful if you have a fixed layout and only want to make certain parts of your page customisable:
import { DropZone, Config } from "@measured/puck";
export const config: Config = {
root: {
render: ({ children }) => {
return (
<div>
{/* children renders the default zone. This can be omitted if necessary. */}
{children}
<div>
<DropZone zone="other-drop-zone">
</div>
</div>
)
}
}
};
The Rules of DropZones
The current DropZone implementation has certain rules and limitations:
- You can drag from the component list on the LHS into any DropZone
- You can drag components between DropZones, so long as those DropZones share a parent (also known as area)
- You can't drag between DropZones that don't share a parent (or area)
- Your mouse must be directly over a DropZone for a collision to be detected
External fields
External fields can be used to import data from a third-party API, such as a headless CMS.
Example
The external
field type enables us to query data from a third party API:
const config = {
components: {
HeadingBlock: {
fields: {
myData: {
type: "external",
fetchList: async () => {
const response = await fetch("https://www.example.com/api");
return {
text: response.json().text,
};
},
},
},
render: ({ myData }) => {
return <h1>{myData.text}</h1>;
},
},
},
};
When the user interacts with this external field, they'll be presented with a list of items to choose from. Once they select an item, the value will be mapped onto the prop. In this case, myData
.
Dynamic prop resolution
Dynamic prop resolution allows developers to change the props for a component after the props have been changed by the user. This is useful for making third-party API calls, such as requesting the latest content from a headless CMS.
resolveData()
resolveData
is defined in the component config, and allows the developer to make asynchronous calls to change the ComponentData after they've been set by Puck. Receives ComponentData and returns ComponentData.
Examples
Basic example
In this example, we remap the text
prop to the title
prop and mark the title
field as read-only.
const config = {
components: {
HeadingBlock: {
fields: {
text: {
type: "text",
},
title: {
type: "text",
},
},
resolveData: async (props) => {
return {
props: {
title: props.text,
},
readOnly: {
title: true,
},
};
},
render: ({ title }) => {
return <h1>{title}</h1>;
},
},
},
};
Combining with external fields
A more advanced pattern is to combine the resolveData
method with external
fields to dynamically fetch data when rendering the component.
const config = {
components: {
HeadingBlock: {
fields: {
myData: {
type: "external",
placeholder: "Select from example.com",
fetchList: async () => {
const response = await fetch("https://www.example.com/api");
return {
id: response.json().id,
};
},
},
title: {
type: "text",
},
},
resolveData: async (props) => {
if (!myData.id) {
return { props, readOnly: { title: false } };
}
const latestData = await fetch(
`https://www.example.com/api/${myData.id}`
);
return {
props: {
title: latestData.json().text,
},
readOnly: {
title: true,
},
};
},
render: ({ title }) => {
return <h1>{title}</h1>;
},
},
},
};
resolveAllData()
resolveAllData
is a utility function exported by Puck to enable the developer to run all their resolveData
methods before rendering the component with <Render>
.
If your resolveData
methods rely on any external APIs, you should run this before rendering your page.
import { resolveAllData } from "@measured/puck";
const resolvedData = resolveAllData(data, config);
React server components
If you want to use React server components, use <Render>
from the @measured/puck/rsc
bundle instead of the main bundle.
import { Render } from "@measured/puck/rsc";
import "@measured/puck/dist/index.css";
export function Page() {
return <Render config={config} data={data} />;
}
If you're using DropZones with React server components, use the puck.renderDropZone
prop provided to your render function instead of the <DropZone>
component.
export const MyComponent: ComponentConfig = {
render: ({ puck: { renderDropZone } }) => {
return (
<div>
{renderDropZone({ zone: "first-drop-zone" })}
{renderDropZone({ zone: "second-drop-zone" })}
</div>
);
},
};
In future, we may deprecate DropZone in favour of renderDropZone.
