Extend Builder with plugins

You can create plugins to customize Builder and the Visual Editor to meet your team's needs. This document covers the areas you can customize with Builder.register(<some-key>):

appTab:the left sidebar of the Builder UI
editor.mainTab: top bar of the Visual Editor
editor.editTab: the panel of the UI that contains the Insert, Options, Style, Layers, Animate, and Data tabs.
editor.insertMenu: the Insert tab
editor.toolbarButton: the topmost section of the Visual Editor that displays features such as the icons for targeting, scheduling, alerts, code, preview, and the Publish button.

The table in the next section provides a screenshot of which part of Builder each of these keys refer to and example of how you might customize it.

Customizable plugin options

Location	Example
`appTab`	Make an app-wide tab that displays and edits content in unique ways using our read and write APIs. For example, make a content calendar so you can view your scheduled content on a calendar that shows when content will go live when, and give the user the ability to drag to reschedule. `import { Builder } from '@builder.io/react'; function CalendarView(props) { return <>{/* Read content and display on a calendar */}</>; } Builder.register('appTab', { name: 'Calendar', path: 'calendar', icon: 'https:/...', component: CalendarView, })`
`editor.mainTab`	Add a new tab located at the top of the preview window to view or edit the current document. For example, create a notes tab so people can post and view notes to collaborate. `import { Builder } from '@builder.io/react'; import { useObserver } from 'mobx-react' const context = require('@builder.io/app-context').default; function NotesTab(props) { const { data } = context.designerState.editingContentModel; return useObserver(() => <textarea value={data.get('notes')} onChange={e => data.set('notes', e.target.value)} /> ); } Builder.register('editor.mainTab', { name: 'Notes', component: NotesTab, })`
`editor.editTab`	Add a new tab located on the left sidebar to edit the currently selected element(s). For example, create a Tailwind UI tab that applies Tailwind classes to elements. import { Builder } from '@builder.io/react'; import { useObserver } from 'mobx-react' const context = require('@builder.io/app-context').default; function TailwindTab(props) { const { selection } = context.designerState; return useObserver(() => <input title="color" type="number" onChange={e => { selection.forEach(el => { let value = e.target.value; el.properties.set('class', `text-gray-${value}`) }) } /> ); } Builder.register('editor.editTab', { name: 'Tailwind', component: TailwindTab, })
`editor.insertMenu`	Override the Insert menu and display custom components. `import { Builder } from '@builder.io/react'; const { designerState } = require('@builder.io/app-context').default; function InsertTab(props) { return <> <div onClick={() => designerState.draggingInItem = 'Custom component 1' } /> <div onClick={() => designerState.draggingInItem = 'Custom component 2' } /> </> } Builder.register('editor.insertMenu', { component: InsertTab, })`
`editor.toolbarButton`	Add a toolbar button. For example, create a workflow status button for custom workflows. `import { Builder } from '@builder.io/react'; const { designerState } = require('@builder.io/app-context').default; function WorkflowButton(props) { return <div onClick={launchApprovalModal}> Pending approval </div> } Builder.register('editor.toolbarButton', { component: WorkflowButton, })`

For an example plugin with multiple options, refer to Builder's campaign plugin example.

Visual Editor settings

Use the following toggles to further customize the Visual Editor:

import { Builder } from '@builder.io/sdk'  Builder.register('editor.settings', {   hideStyleTab: false,      // Hide the Style tab   hideMainTabs: false,      // Hide all main tabs   hideDataTab: false ,      // Hide the Data tab   hideOptionsTab: false,    // Hide the Options tab   hideToolbar: false,       // Hide the main toolbar   hideHeatMap: false,       // Hide the Heatmap button   hidePageUrlEditor: false, // Hide the Page URL editor   hideAnimateTab: false,    // Hide the Animate tab   hideInsertTab: false,     // Hide the Insert tab   hideTargeting: false,     // Hide the Targeting UI   hideHelpWidget: false,    // Hide help widget   disableTargetingFields: [], // Array of targeting fields to disable   // disableTargetingFields can be any targeting, like   // ['url', 'urlPath', 'device', 'yourCustomTargetingField']   disableOverflowButtons: [], // Disables buttons in the overflow menu next to Publish   // disableOverflowButtons can be one of    // ['archive', 'duplicate', 'move', 'copy', 'globalSymbol', 'share', 'exportToPdf', 'getCode', 'fiddle', 'delete'] })

Accessing application state

Builder's open source examples uses this pattern, demonstrate a pattern that provides access to application state, including the current editing document and API access.

Visit builder/packages/app-context/index.d.ts on GitHub for more information and type definitions that are available in app state.
