Quill Blot Formatter
A quill module to format document blots. Heavily inspired by quill-image-resize-module. Out of the box supports resizing and realigning images and iframe videos, but can be easily extended using BlotSpec
and Action
.
Demo
Installation
Using yarn
:
yarn add @chuyik/quill-blot-formatter
Using npm
:
npm install --save @chuyik/quill-blot-formatter
Usage
As Module
import Quill from 'quill';
// from the index, which exports a lot of useful modules
import BlotFormatter from 'quill-blot-formatter';
// or, from each individual module
import BlotFormatter from 'quill-blot-formatter/dist/BlotFormatter';
Quill.register('modules/blotFormatter', BlotFormatter);
const quill = new Quill(..., {
modules: {
...
blotFormatter: {
// see config options below
}
}
});
Script Tag
quill-blot-formatter.min.js
is provided which exports the same modules as index.js
under the global QuillBlotFormatter
.
<script src="<quill>"></script>
<script src="node_modules/quill-blot-formatter/dist/quill-blot-formatter.min.js"></script>
<script>
Quill.register('modules/blotFormatter', QuillBlotFormatter.default);
const quill = new Quill(..., {
modules: {
...
blotFormatter: {
// see config options below
}
}
}
});
</script>
BlotSpec
The BlotSpec
classes define how BlotFormatter
interacts with blots. They take the BlotFormatter
as a constructor arg and have the following functions:
init(): void
Called after all specs have been constructed. Use this to bind to quill events to determine when to activate a specific spec.
getActions(): Class<Action>[]
The actions
that are allowed on this blot. The default is [AlignAction, ResizeAction, DeleteAction]
.
getTargetElement(): ?HTMLElement
When the spec is active this should return the element that is to be formatter
getOverlayElement(): ?HTMLElement
When the spec is active this should return the element to display the formatting overlay. This defaults to return getTargetElement()
since they will typically be the same element.
setSelection(): void
After the spec is activated this should set the quill selection using setSelection
. Defaults to quill.setSelection(null)
.
onHide(): void
Called when the spec is deactivated by the user clicking away from the blot. Use this to clean up any state in the spec during activation.
Notes
Each spec should call this.formatter.show(this);
to request activation. See specs/
for the built-in specs.
Action
The Action
classes define the actions available to a blot once its spec is activated. They take the BlotFormatter
as a constructor arg and have the following functions:
onCreate(): void
Called immediately after the action is created. Use this to bind quill events and create elements to attach to the overlay.
onUpdate(): void
Called when the formatter has changed something on the blot. Use this to update any internal state.
onDestroy(): void
Called when the formatter is hidden by the user.
See actions/
for the existing actions.
Options
Using quill module options it's easy to disable existing specs, actions, or to override any of the styles provided by this module. For example: if you wanted to remove resizing, support only images, and change the overlay border the following config would work:
import Quill from 'quill';
// from main module
import BlotFormatter, { AlignAction, DeleteAction, ImageSpec } from 'quill-blot-formatter'
// or, from individual modules
import BlotFormatter from 'quill-blot-formatter/dist/BlotFormatter';
import AlignAction from 'quill-blot-formatter/dist/actions/align/AlignAction';
import DeleteAction from 'quill-blot-formatter/dist/actions/DeleteAction';
import ImageSpec from 'quill-blot-formatter/dist/specs/ImageSpec';
Quill.register('modules/blotFormatter', BlotFormatter);
class CustomImageSpec extends ImageSpec {
getActions() {
return [AlignAction, DeleteAction];
}
}
const quill = new Quill(..., {
modules: {
...
blotFormatter: {
specs: [
CustomImageSpec,
],
overlay: {
style: {
border: '2px solid red',
}
}
}
}
});
Notes
- For all supported options as well as the default see
Options
. - object properties are merged, but array properties override the defaults.
- To completely disable styles (
overlay.style
,resize.handleStyle
, etc) set those tonull
