    Webcards Editor

    Webcards Editor is a powerful WYSIWYG page builder built on React/Redux in Typescript.


    npm install webcards-editor


    import * as React from 'react';
    import * as ReactDOM from 'react-dom';
    import PageEditor from 'webcards-editor';
    import  *  as  content  from  'webcards-editor/dist/editor/content/content';
                    content.generateText("Hello world!"{ variant: "h1" })
            onSave={(items, onComplete) => {
                saveToServer(items, () => {
                    alert("Save complete!");


    This is a WIP

    I am building this as part of a project and it's still under development. Please submit any issues or feature requests to GitHub.


    The API is currently still in development and there may be some breaking changes in the future.


    import PageEditor from 'webcards-editor';

    The PageEditor component is the main component you'll have to use if all you want is to implement a simple page editor. This is the component responsible for loading content from the server into the editor and saving content from the editor to the server. All the details are handled by this component.

    Property Type Required Description
    content ContentItem[] Optional The initial content of the page. This can be loaded in from the server as it is just a simple JSON object. It can also be generated manually using the content namespace (see below).
    bodyOffset number Optional The root of the content will try to automatically scale itself to 100vh, which can be an obstacle if you have extra toolbars above the editor. Settings this number to e.g. 100 will set the body to be 100vh - 100px.
    onSave (items: ContentItem[], onComplete: ()=>void) Optional When the save button on the toolbar is clicked this function is invoked and you can save the items to the server. When saving is done simply call onComplete() to stop saving.

    Namespace content

    import * as content from 'webcards-editor/dist/editor/content/content';

    interface ContentItem

    • The ContentItem interface defines what an item in the editor is. Since we're never dealing with HTML directly this is the main type we use to determine what the page looks like. These are what you'll be saving and loading from the server, and you can use generators to convert these items into HTML.

    • It is not recommended you create these objects manually and instead to use the utility functions instead (see below). Creating them manually requires a lot of house-keeping, such as giving them unique IDs, maintaining parent references and their positions within a container.

    • This table is meant simply as a reference for querying the items.

    Property Type Required Description
    id string Required A unique ID for the item
    type ItemType Required The type of element. See ItemType.
    parent ContainerItem Required The item containing this item
    position number Required The index of the item relative to its siblings.
    data ContentData Required Any information associated with the item, including style attributes. Custom attributes are allowed here.

    interface ContainerItem

    • A ContainerItem extends ContentItem to add a children property. It's exactly like a ContentItem except for the fact that it can contain other items itself.

    • As above, it is not recommended to create these objects manually. Use the utility functions instead.

    Property Type Required Description
    children ContentItem[] Required An array of ContentItems (or ContainerItems) which act as the children of this container.

    interface ContentData

    Property Type Required Description
    style CSSProperties Required React CSS properties
    * any Optional You can add any other properties to the data item which might make it more useful. For example, the column type has a span attribute. This is also where you'd put your classNames.

    Content creation utilities

    createContentItem(type: string, data: ContentData)=>ContentItem

    • Creates a blank item with a type and associated data. The item type is derived from the ID string passed in as the first argument. This is a bare-bones function and may not create any associated items (such as child elements in a template).

    createContainerItem(type: string, data: ContentData, children: ContentItem[])=>ContainerItem

    • Like createContentItem, this will do the same but return a ContainerItem with an array of children attached. This will automatically set the parent reference of each child as well as their positions.

    generateDefault(type: string, data?: ContentData, children?: ContentItem[])=>ContentItem

    • Generates a default instance of an ItemType, identified by type. Unlike createContentItem this will do extra things that the ItemType wants, such as applying styles or even adding child items.

    generateText(text: string, options?)=>ContentItem

    • Generates a text item with populated with text. options is a ContentData object so must include a style attribute (even if empty), and a variant (h1 - h6, p, span)

    generateContainer(children: ContentItem[], options?: ContentData)=>ContainerItem

    • Utility to create a generic container with children.

    generateRow(children?: ContentItem[])=>ContainerItem

    • A row is a special type of container which can only contain columns. This is akin to rows and columns in Bootstrap.

    generateColumn(span: IOneToTwelve, children?: ContentItem[])=>ContainerItem

    • Generates a column with a span between 1 and 12.

    Namespace itemTypes

    import * as itemTypes from 'webcards-editor/dist/editor/content/itemTypes';

    Note: This namespace is not yet complete. Adding new items types and categories is not currently possible without editing the source code. This is meant as a reference for querying items and their types.

    interface ItemType

    Property Type Required Description
    id string Required A unique ID for the item type, e.g. "text". This is used when calling content.createItemType().
    name string Required A human-friendly name which will be displayed in the left item list drawer.
    desc string Required A human-friendly description which will be displayed when hovering over the handle in the left item list drawer.
    validChildren string or string[] Optional A list of valid children that the item can contain. Use * for all types.
    invalidChildren string[] Optional For some items it's easier to specify what they can't contain. For example, container can't contain column as only row can contain items of type column.
    edittable boolean Required Whether the item can be edited or not.
    customTypeSettings CustomTypeSettings Optional Additional settings for the type. These will generate controls in the right settings drawer. (See custom).
    generateDefault (children?:ContentItem[], options?:ContentData)=>ContentItem Optional Generates a default instance of this type.
    generateProps (item: ContentItem)=>any Optional Generates HTML attributes for an item so it can be rendered by React. Useful for doing things such as, <MyWrapper {...item.type.generateProps(item)}></MyWrapper>. See Generators.

    interface ItemTypeCategory

    • This is a simple interface to help categorise items in the left item list drawer.

    • Note: It is still not possible to create new item type categories.

    Property Type Required Description
    name string Required The human-readable name for the category.
    types ItemType[] Required A list of items in this category.

    Namespace custom

    import * as custom from 'webcards-editor/dist/editor/content/custom';

    • Note: This namespace is not yet complete and is simply meant as a reference.

    • Custom settings can be applied to item types which will render controls for them in the right settings drawer. For example, a column might have a custom setting for its span, which might render a slider to control it.

    enum TypeTag

    • This is a the type of data that a custom setting can manipulate.
    Property Description
    NUMBER A simple numerical value.

    interface ICustomType

    • This is a data point that can be manipulated by the custom settings controls. It includes the type of data that can be manipulated, such as NUMBER, and any rules associated with the setting of that data.
    Property Type Required Description
    type TypeTag Required The type of data to be manipulated.
    rules any Required Any associated rules for manipulating this data.

    interface CustomTypeSetting

    • A custom setting as it will be seen in the UI. This includes its name, the property that you want to control and any rules about how that property is controlled.
    Property Type Required Description
    title string Required The human readable name of the setting.
    prop string Required The ContentData property that we want to manipulate.
    type ICustomType Required The type and rules needed to manipulate the ContentData property.

    interface CustomTypeSettings

    Property Type Required Description
    props CustomTypeSetting[] Required An array of custom settings for this type.

    createNumberType(rules?: any)=>ICustomType

    • A utility to create a type and rules for custom settings.


    Below is an example of how custom type settings can be implemented. This particular example is used to change the column span of a column.

    export  const  ColumnCustomSettings:  CustomTypeSettings  = {
        props: [
            // The property we want to affect:
            // The 'span' property of the item's ContentData.
            // This will create a slider in the right drawer
            // with the range between 1 and 12, stepping 1 at a time.
            // Moving this slider will
            // automatically update the span of the column
                title:  "Span",
                prop:  "span",
                type:  createNumberType({
                    min:  1,
                    max:  12,
                    step:  1


    npm i webcards-editor
