    This is a plugin that only has a peer dependency to piral-core. What piral-modals brings to the table is a set of Pilet API extensions that can be used with piral or piral-core to easily trigger the display of modal dialogs from pilets.

    Why and When

    If you have modal dialogs on your page that piral-modals gives you a nice abstraction over registering components for them. These items will be stored in the global state container and will be filtered on a given dialog name. Thus the plugin makes only sense if you want to have consistent dialog management.

    Alternative: You could simply use an event to trigger opening a dialog. The event could transport a React component which would then be globally used. Alternatively, each pilet would come up with its own dialog design and management system.


    We also have a video for this plugin:



    The following functions are brought to the Pilet API.


    Adds a modal dialog definition to the app shell. Can be called from any pilet using the specified name.


    Removes a modal dialog definition from the app shell.


    Shows the modal dialog registered with the provided name.

    Does not open in case no modal dialog using the provided name is available (i.e., registered in the app shell).


    ::: summary: For pilet authors

    You can use the showModal function from the Pilet API to show a modal dialog registered by any pilet. In case of a naming conflict the dialogs from the current pilet are preferred.

    Example use:

    import { PiletApi } from '<name-of-piral-instance>';
    export function setup(piral: PiletApi) {
      piral.showModal('my-modal', {
        someValue: 42,

    You can use the registerModal function from the Pilet API to add a new modal dialog in the app shell.

    Example use:

    import { PiletApi } from '<name-of-piral-instance>';
    import { MyModal } from './MyModal';
    export function setup(piral: PiletApi) {
      piral.registerModal('my-modal', MyModal);

    You can use the unregisterModal function from the Pilet API to remove a previously added modal dialog from the app shell.

    Example use:

    import { PiletApi } from '<name-of-piral-instance>';
    export function setup(piral: PiletApi) {


    ::: summary: For Piral instance developers

    The provided library only brings API extensions for pilets to a Piral instance.

    For the setup of the library itself you'll need to import createModalsApi from the piral-modals package.

    import { createModalsApi } from 'piral-modals';

    The integration looks like:

    const instance = createInstance({
      // important part
      plugins: [createModalsApi()],
      // ...

    Via the options the globally available dialogs can be defined.

    For example:

    const instance = createInstance({
      // important part
      plugins: [createModalsApi({
        dialogs: [
            name: 'userinfo',
            component: UserInfoModal,
      // ...

    In order to host the modal dialogs you'll need to embed the Modals component somewhere in your layout.

    As an example:

    import { Modals } from 'piral-modals';
    const MyLayout = ({ children }) => {
        <Modals />

    If you want to customize the styling (which you should) make sure to register components such as ModalsHost (shell for the modals) or ModalsDialog (wrapper for an individual dialog) via, e.g., <SetComponent name="ModalsHost" component={MyModalsHost} />.


    You can customize the available dialogs and their options.

    import type {} from 'piral-modals';
    declare module 'piral-modals/lib/types' {
      // interface shared across all dialogs defined in PiralCustomModalsMap
      interface BaseModalOptions {
        common?: boolean;
      interface PiralCustomModalsMap {
        login: {
          required?: boolean;
    // now showModal("login", { required: true, common: true }) is strongly typed in pilets
