React SDK - Docs

React project requirements

Your app MUST use SCSS for styling.

To install the npm libraries provided by FlowX.AI you will need to obtain access to the private FlowX.AI Nexus registry. Please consult with your project DevOps.

The library requires React 19, npm ≥ 11.0.0 and node ≥ 24.0.0.

Installing the library

Use the following command to install the renderer library and its required dependencies:

Installing react and react-dom can be skipped if you already have them installed in your project.

npm install \
  react@19 \
  react-dom@19 \
  @flowx/core-sdk@<version> \
  @flowx/core-theme@<version> \
  @flowx/react-sdk@<version> \
  @flowx/react-theme@<version> \
  @flowx/react-ui-toolkit@<version> \
  air-datepicker@3 \
  axios \
  ag-grid-react@32

Replace <version> with the correct version corresponding to your platform version.To find the right version, navigate to: Release Notes → Choose your platform version → Deployment guidelines → Component versions.

Initial setup

Once installed, FlxProcessRenderer will be imported from the @flowx/react-sdk package.

Theming

Component theming is done through the @flowx/react-theme library. The theme id is a required input for the renderer SDK component and is used to fetch the theme configuration. The id can be obtained from the admin panel in the themes section.

Authorization

It’s the responsibility of the client app to implement the authorization flow (using the OpenID Connect standard). The renderer SDK will expect the authToken to be passed to the FlxProcessRenderer as an input.

import { FlxProcessRenderer } from '@flowx/react-sdk';

export function MyFlxContainer() {
    return <FlxProcessRenderer
        apiUrl={'your API url'}
        authToken={...}
        processName={...}
        processStartData={...}
        workspaceId={...}
        processApiPath={...}
        themeId="12345678-1234-1234-1234-123456789012"
        staticAssetsPath={...}
        locale="en-US"
        language="en"
        projectInfo={{
            projectId: ...
        }}
        organizationId={...}
      />
}

The FlxProcessRenderer component is required in the app module where the process will be rendered. The component accepts a props where you can pass extra config info, register a custom component or custom validators. Custom components will be referenced by name when creating the template config for a user task. Custom validators will be referenced by name (customValidator) in the template config panel in the validators section of each generated form field.

import { FlxProcessRenderer } from '@flowx/react-sdk';

export function MyFlxContainer() {
    return <FlxProcessRenderer
        apiUrl={'your API url'}
        language={...}
        authToken={...}
        processName={...}
        processStartData={...}
        workspaceId={...}
        processApiPath={...}
        themeId="12345678-1234-1234-1234-123456789012"
        components={{ MyCustomComponentIdentifier: MyCustomComponent }}
        validators={{ customValidator: (...params: string[]) => (v: string) => v === '4.5'}}
        staticAssetsPath={...}
        locale="en-US"
        language="en"
        projectInfo={{
            projectId: ...
        }}
        organizationId={...}
      />
}

Analytics

The SDK provides a mechanism for collecting analytics events through a unified CustomEvent system. These events can be used to track screens and action events.

To use analytics features, make sure you’ve imported the necessary SDK module:

import {
   ANALYTICS_EVENTS,
   AnalyticsData,
   pushAnalyticsData,
} from '@flowx/core-sdk';

Emitting analytics events

Analytics events are dispatched using the pushAnalyticsData(payload: AnalyticsData) method. The SDK defines two event types:

enum ANALYTICS_EVENTS {
  SCREEN = 'SCREEN',
  ACTION = 'ACTION',
}

Each analytics event should be an object of type AnalyticsData:

type AnalyticsData = {
  type: ANALYTICS_EVENTS;
  value: string;
  screen?: string;
  component?: string;
  label?: string;
  customPayload?: object;
}

The value property represents the identifier set in the process definition.For ACTION type events there are some additional properties provided:

component - The type of component triggering the action
label - The label of the component
screen - The identifier of the screen containing the component, if set

Listening for analytics events

You can subscribe to analytics events using the standard CustomEvent API:

const analyticsListener = (event: CustomEvent<AnalyticsData>) => {
  console.log('Received flowx:analytics event:', event.detail);
}

useEffect(() => {
  document.addEventListener('flowx:analytics', analyticsListener)

  return () => {
    document.removeEventListener('flowx:analytics', analyticsListener)
  }
}, [])

Ensure that you remove the event listener on component destruction to avoid memory leaks.

Custom payload

This allows you to capture and send custom data alongside standard analytics events. When analytics custom payload is configured in FlowX Designer, the renderer automatically processes variable substitution and includes the resulting data in analytics events.

Receive custom payload configuration

The renderer receives the analytics configuration as a JSON string with variable placeholders:

"analyticsCustomPayload": "{\n \"name\": ${app.input}\n}"

Process variable substitution

The SDK replaces variables with actual values from the process data store:

{
    "name": "${app.input}",
    "client": "${app.client}",
    "amount": "${app.amount}"
}

Add to analytics event

The processed payload is included in the analytics event under the customPayload property:

// Analytics event structure with custom payload
{
    type: 'ACTION', // or 'SCREEN'
    info: {
        value: 'Save personal data',
        screen: 'Personal Data',
        component: 'BUTTON',
        label: 'Save',
        customPayload: {
            name: "john",
            client: { id: "123", name: "John Doe" },
            amount: 1500
        }
    }
}

Starting a process

Prerequisites

Process Name: You need to know the name of the process you want to start. This name is used to identify the process in the system.
FlowX Project UUID: You need the UUID of the FlowX Project that contains the process you want to start. This UUID is used to identify the project in the system.
Locale: You can specify the locale of the process to apply date, currency, and number formatting to data model values.
Language: You can specify the language used to localize the enumerations inside the app.

Getting the project UUID

The project UUID can be obtained from the FlowX Dashboard. Navigate to the Projects section and select the project you want to start a process in. The UUID can be copied from the project actions popover.

Getting the process identifier

Open the FlowX Designer, navigate to the process, and copy the process name from the breadcrumbs. Use this value as processName.

Initializing the process renderer

To start a process, you need to initialize the FlxProcessRenderer component in your app. The component accepts various props that define the process to start, the theme to use, and other configuration options.

import { FlxProcessRenderer } from '@flowx/react-sdk';

export function MyFlxContainer() {
    return <FlxProcessRenderer
        {...props}
        locale="en-US"
        language="en"
        processName={processName}
        projectInfo={{ projectId }}
      />
}

Custom components

Custom components receive an input prop of type FlxCustomComponentData and are registered through the components parameter of <FlxProcessRenderer />.

The object keys passed in the components prop MUST match the custom component names defined in the FlowX process.

Process data mapped through inputKeys is available on input.data. The value is whatever lives at the configured path in the process model - it can be an object or a primitive.

Process actions are available on input.actionsFn, keyed by action name.

interface FlxCustomComponentData {
  data: any                                                          // value at the configured inputKey path - object or primitive
  actions: ProcessAction[]                                           // metadata for each bound action
  actionsFn: Record<string, (params?: any) => Observable<any>>      // call to trigger a process action; returns an Observable
}

Each custom component receives four props:

Prop	Type	Description
`input`	`FlxCustomComponentData`	Process data and bound actions
`registerValidation`	`(fn: () => boolean \| Promise<boolean>) => void`	Register a validation function. The SDK calls it when the user submits the process step. Return `true` to pass, `false` to block.
`saveData`	`(fn: () => Record<string, unknown>) => void`	Register a data extractor. The SDK calls it on submit to collect values to write back to the process model.
`isSubmitted`	`boolean`	`true` after the first submit attempt - use to show validation errors.

export const MyCustomComponent = ({
  input,
  registerValidation,
  saveData,
  isSubmitted,
}: {
  input: FlxCustomComponentData
  registerValidation: (fn: () => boolean | Promise<boolean>) => void
  saveData: (fn: () => Record<string, unknown>) => void
  isSubmitted: boolean
}) => {
  const { data, actionsFn } = input
  // data - the value mapped via inputKeys; e.g. { firstName: 'John' } or a primitive
  // actionsFn['save_order']() - triggers the 'save_order' process action
}

To add a custom component in the template config tree, we need to know its unique identifier and the data it should receive from the process model.

The properties that can be configured are as follows:

Identifier - This enables the custom component to be displayed within the component hierarchy and determines the actions available for the component.
Input keys - These are used to specify the pathway to the process data that components will utilize to receive their information.
Event Handlers - actions defined here will be made available to the custom component

Prerequisites (before creation)

React Knowledge: You should have a good understanding of React, as custom components are created and imported using React.
Development Environment: Set up a development environment for React development, including Node.js and npm (Node Package Manager).
Component Identifier: You need a unique identifier for your custom component. This identifier is used for referencing the component within the app.

Creating a custom component

To create a Custom Component in React, follow these steps:

Create a new React component.
Implement the necessary HTML structure, TypeScript logic, and SCSS styling to define the appearance and behavior of your custom component.

Importing the component

After creating the Custom Component, you need to import it into your app. In your <FlxProcessRenderer /> component, add the following property:

<FlxProcessRenderer
  {...otherProps}
  components={{ MyCustomComponentIdentifier: MyCustomComponent }}
/>

Using the custom component

Once your Custom Component is declared, you can use it for configuration within your app.

Data input and actions

The Custom Component accepts input data from processes and can also include actions extracted from a process. These inputs and actions allow you to configure and interact with the component dynamically.

Extracting data from processes

There are multiple ways to extract data from processes to use within your Custom Component. You can utilize the data provided by the process or map actions from the BPMN process to React actions within your component.

Make sure that the React actions that you declare match the names of the process actions.

Styling with CSS

To apply CSS classes to UI elements within your Custom Component, you first need to identify the UI element identifiers within your component’s HTML structure. Once identified, you can apply defined CSS classes to style these elements as desired. Example:

Additional considerations

Naming Conventions: Be consistent with naming conventions for components, identifiers, and actions. Ensure that React action names match the names of process actions.
Component Hierarchy: Understand how the component fits into the overall component hierarchy of your app. This will help determine where the component is displayed and what actions are available for it.
Documentation and Testing: Document your custom component thoroughly for future reference. Additionally, testing is crucial to ensure that the component behaves as expected in various scenarios.
Security: If your custom component interacts with sensitive data or performs critical actions, consider security measures to protect the app from potential vulnerabilities.
Integration with FlowX Designer: Ensure that your custom component integrates with FlowX Designer, as it is part of the app’s process modeling capabilities.

Custom validators

You may also define custom validators in your FlowX processes and pass their implementation through the validators prop of the <FlxProcessRenderer /> component. The validators are processed through a custom validation layer backed by Valtio state management, taking into account how the error messages are defined in your process. A validator must have the following type:

const customValidator = (...params: string[]) => (v: any) => boolean | Promise<boolean>

The object keys passed in the validators prop MUST match the custom validator names defined in the FlowX process.

Process end handling

The SDK provides a mechanism for container applications to handle process completion events through the onProcessEnded callback. This allows you to implement custom logic when a main process reaches an end state, such as redirecting users or triggering cleanup operations. The onProcessEnded callback is triggered when the main process (not subprocesses) reaches any terminal state:

FINISHED - Process completed successfully
FAILED - Process encountered an error
ABORTED - Process was manually terminated
Other terminal states

Only the main process triggers this callback. Subprocess completions do not trigger the callback to avoid unnecessary interruptions during complex process flows.

Implementation

To handle process end events, pass a function to the onProcessEnded prop of the <FlxProcessRenderer /> component:

import { FlxProcessRenderer } from '@flowx/react-sdk';

export function MyFlxContainer() {
  const handleProcessEnd = () => {
    // Your custom logic here
    console.log('Process has ended');
    
    // Example: Redirect to home page
    window.location.href = '/dashboard';
  };

  return (
    <FlxProcessRenderer
      {...otherProps}
      onProcessEnded={handleProcessEnd}
    />
  );
}

Custom loader

The SDK provides a mechanism for container applications to customize the loader UI displayed during process execution. This allows you to replace the default FlowX loader with your own custom implementation based on different loading scenarios.

Configuration

To configure custom loaders, pass them through the customLoader prop of the <FlxProcessRenderer /> component:

import { FlxProcessRenderer } from '@flowx/react-sdk';

// Define your custom loader components
const StartProcessLoader = () => (
  <div className="custom-start-loader">
    <div className="spinner" />
    <p>Starting process...</p>
  </div>
);

const SpecificActionLoader = () => (
  <div className="custom-specific-action-loader">
    <div className="spinner" />
    <p>Executing specific action...</p>
  </div>
);

// Register the custom loaders in your component
export function MyFlxContainer() {
  return (
    <FlxProcessRenderer
      {...otherProps}
      customLoader={{
        startProcess: <StartProcessLoader />,
        // reloadProcess: <ReloadProcessLoader />,
        // defaultAction: <DefaultActionLoader />,
        // defaultUpload: <DefaultUploadLoader />,
        actions: {
          action1: <SpecificActionLoader />,
          // action2: <SaveDataLoader />,
        },
      }}
    />
  );
}

API specification

The customLoader prop accepts an object of type CustomLoader:

type CustomLoader = {
  actions?: Record<string, ReactNode>
  startProcess?: ReactNode
  reloadProcess?: ReactNode
  defaultAction?: ReactNode
  defaultUpload?: ReactNode
}

Loader types

startProcess - Displayed when starting or resuming a process
reloadProcess - Displayed when reloading a process
defaultAction - Default loader for actions when loaderType is 'action'. Used when no specific action loader is found in the actions record
defaultUpload - Default loader for file uploads when loaderType is 'upload'
actions - Record mapping specific action identifiers to custom loaders. When an action is executed, the SDK will first check for a matching entry in this record before falling back to defaultAction

Fallback behavior

If no custom loader is provided for a specific type, the SDK will automatically fall back to the built-in FlowX loader. This ensures your app continues to function even with partial custom loader configuration.

You can use any React components, including those with animations, styled components, or media assets, to create rich loading experiences that match your app’s design system.

`staticAssetsPath`	Path for static resources	`string`	❌	(set via environment)

Returns: Promise resolving to an object containing:

view: The view configuration object
enumerations: Available enumeration options for filters
filterOperators: Available filter operators for each column

Fetching tasks

`fetchViewTasks`

Fetches tasks for a specific view with support for sorting, filtering, pagination, and search.

const response = await fetchViewTasks(
  sort,           // Array of sort configurations
  filters,        // Array of filter configurations
  searchTerm,     // Search string
  view,           // View object from getTaskManagerResources

Starting a UI Flow

Prerequisites

UI Flow name: You need the name of the UI Flow to start, passed as uiFlowName.
FlowX Project UUID: The appInfo.appId value, which identifies which project the UI Flow belongs to. Obtain it the same way as for processes: FlowX Dashboard → Projects → copy UUID from the project actions popover.
Process API path: The processApiPath subpath used by the embedded process renderer when the UI Flow navigates into a full-screen process.

Getting the UI Flow name

Open the FlowX Designer and navigate to UI Flows. The flow name displayed in the list is the value to pass as uiFlowName.

Initializing the UI Flow renderer

Minimal working example:

import { FlxUiFlowRenderer } from '@flowx/react-sdk'

export function MyUiFlowContainer() {
  return (
    <FlxUiFlowRenderer
      apiUrl="https://yourDomain.dev"
      authToken={authToken}
      processApiPath="onboarding"
      language="en"
      locale="en-US"
      themeId={themeId}
      staticAssetsPath={staticAssetsPath}
      workspaceId={workspaceId}
      appInfo={{ appId: projectId }}
      isDraft={false}
      cache={true}
      uiFlowName={uiFlowName}
    />
  )
}

Passing initial parameters: `startParams`

Use startParams to inject query-string key/value pairs into the UI Flow at startup. The values are available inside the flow as URL query parameters.

<FlxUiFlowRenderer
  {...requiredProps}
  startParams={{ referralCode: 'REF123', skipIntro: true }}
/>

startParams is read once at initialization. To trigger a full re-initialization, change one of the primitive props such as uiFlowName.

Utility API

These functions and hooks are exported from @flowx/react-sdk and can be used independently of the renderer components.

import {
  useEnumeration,
  getEnumeration,
  getStaticAsset,
  getSubstitutionTag,
} from '@flowx/react-sdk'

`useEnumeration`

React hook that fetches enumeration values reactively. Re-fetches whenever name or parentName changes.

const values = useEnumeration(name: string, parentName?: string, cached?: boolean): NomenclatorValue[]

Parameter	Description	Type	Mandatory
`name`	Enumeration name	`string`	✅
`parentName`	Parent enumeration name for cascading	`string`	❌
`cached`	Use cached result when available	`boolean`	❌

`getEnumeration`

Async function to fetch enumeration values imperatively.

const values = await getEnumeration(name: string, parentName?: string, cached?: boolean)

`getStaticAsset`

Resolves a static asset URL by its key.

const url = getStaticAsset(key: string)

`getSubstitutionTag`

Resolves a substitution tag value by its key.

const value = getSubstitutionTag(key: string)

Custom CSS

The renderer SDK allows you to pass custom CSS classes on any component inside the process. These classes are then applied to the component’s root element. To add a CSS custom class to a component, you need to define the class in the process designer by navigating to the styles tab of the component, expanding the Advanced accordion and writing down the CSS class.

The classes will be applied last on the element, so they will override the classes already defined on the element.

Storybook

Below you find a Storybook which demonstrates how components behave under different states, props, and conditions, it allows you to preview and interact with individual UI components in isolation, without the need for a full-fledged app:
