    # React PlaceMoulder React Place Moulder uses existing component structure to render loading skeletons with very minimal code changess. Click here for Live Demo and for code click Example Repo Link This is more of a philosophy which can be extended to any framework in Frontend.

    • Works well with dumb or presentational component.
    • Make sure you do not have any analytics/tracking code in the component


    • Uses exisiting component structure ( provided Component is dumb/presentational).
    • While Modifying Component, skeleton is not required to be modified as per new design.

    How it works

    • Class name stensil ( spelling mistake is intentional to avoid accidental clash with correct spelling ) is required to be added to render stencil when the data is being loaded.
    • Create a dummy data or Schema and pass it to your component.
    • To render loading state of the list, use StencilList HOC, or to show loading state of individual component, use Stencil HOC. See props table for accetable props.


    prop type Description
    data* object data is dummy or representational data which will be used to determine the dummy space occupied by the DOM element
    length number Number of repetitive skeletons required to fill in the placeholder list
    schema* object If data is not provided, provide schema of the props required by Component.
    Component ReactElement Component for which we want to generate skeleton on the fly


    prop type Description
    Children ReactElement Component on which loading state is required
    repeat number Number of times to repeat the skeleton placeholder


    prop type Description
    Children ReactElement Component on which loading state is required

    Available selectors to achieve desired result. Add required class name along with other classes where you want to show loading state.

    To override or extend visuals, extend following classes or add some rules here and use it in your app:

    Selector Class Description
    stensil To get loading state
    stensil-ignore To ignore the component in the loading state. Won't show stencil over there
    stensil-dark Dark background, useful in image loaders
    stensil-svg To get the exact shape of the SVG as a stencil loader
    stensil-para To show the paragraph, can be used where there is short description used

    You can have your own classes to override visuals in loading behaviour. For that wrap your css under the .enable-stensil selector and just use it in your application.

    createObjectFromSchema - method

    • Takes object schema as an argument and returns dummy component props JSON. It supports nested object structure as well.


    Follow simple following steps

    1. Importing

    Refer Live Examples for more clarity

    import {
    } from "react-placemoulder";
    .... your code ...

    2. To render loading state of the whatsapp card, add stensil class name to the appropriate DOM element for data to be rendered.

    const WhatsAppCard = props => (
      <div className="whatsapp-card">
        <div className="whatsapp-avatar stensil">
          <img src={props.avatar} alt={} className="stensil-ignore" />
        <div className="whatsapp-chat-frame">
          <span className="whatsapp-name stensil">{}</span>
          <p className="whatsapp-last-chat stensil">{props.lastChat}</p>
        <div className="whatsapp-right-block">
          <div className="stensil">{props.lastSeen}</div>

    3. Invoke HOC when the data is being loaded. wData is similar in schema with actual data. Its nothing but props object for the WhatsAppCard. Alternatively you can also use schema.

        {loading ? (
              <StencilList length={3} Component={WhatsAppCard} data={wData} />
            ) : (
              [...Array(3)].map((_, index) => (
                <WhatsAppCard key={index} {...wData} />

    OR using StencilWrapper which accepts only one child

        {loading ? (
              <StencilWrapper repeat={3}>
                  <WhatsAppCard {...wData} />
            ) : (
              ... render your cards

    4. Provide data or schema. Here data takes precedence over schema.

    Example of schema: Where numbers against prop key indicated average length ( decided by you ) to show the stencil.

      name: 12,
      lastChat: 65,
      lastSeen: 10

    Where your dummy data can be like this:

      name: "Mr Developer",
      lastChat: "I created stencils !!!",
      lastSeen: "12:30 PM"
