    Piral Configs · GitHub License npm version tested with jest Gitter Chat

    This is a plugin that only has a peer dependency to piral-core. What piral-configs brings to the table is a set of Pilet API extensions that can be used with piral or piral-core.

    By default, these API extensions are not integrated in piral, so you'd need to add them to your Piral instance.

    Why and When

    For whitelabel products and generic applications configuration may be applied to the frontend. This could also be used as further personalization on a user-defined basis. In any case the piral-configs plugin provides two ways to fully leverage frontend configuration:

    1. Each pilet can define how it can be configured and what default values to apply.
    2. Injected configuration is validated against the configuration schema. Different values are only applied if they fit into the schema.

    This plugin does not make any statement how the configuration is retrieved. Usually, it will be loaded from the backend when the application starts, but you could also go for something like storing the information in localStorage or having a pre-determined configuration embedded in your application. The door is open.

    Alternatives: Pilets can ready configuration values from the global data store or state container. They are responsible for evaluating these values and falling back to another value.


    We also have a video for this plugin:



    The following functions are brought to the Pilet API.


    Defines the config schema to be used by the pilet.


    Gets the currently active configuration.


    ::: summary: For pilet authors

    Just use defineConfigSchema in your setup to define your configuration checker and the default values. Later you can access the retrieved configuration via getCurrentConfig.

    A quick example:

    export function setup(app: PiletApi) {
      // define the schema and the default value
      const configSchema = {
        type: 'object',
        properties: {
          increment: {
            type: "number",
            description: "Defines the value to add when the counter is clicked.",
      const defaultConfig = {
        increment: 1,
      app.defineConfigSchema(configSchema, defaultConfig);
      const { increment } = app.getCurrentConfig();
      app.registerExtension('home-dashboard', () => {
        const [count, setCount] = React.useState(0);
        return (
            onClick={ev => {
              setCount(count => count + increment);

    Make sure you use getCurrentConfig after the configuration schema has been defined.


    ::: 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 createConfigsApi from the piral-configs package.

    import { createConfigsApi } from 'piral-configs';

    The integration looks like:

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

    There are no options available.
