Dopt React SDK


The Dopt React SDK is a framework-specific client for accessing Dopt's blocks and flows APIs, allowing you to bind user flow state defined in Dopt to your UI to build onboarding and engagement flows.

The SDK lives in our open-source monorepo odopt.

It is published to npm as @dopt/react.

Check out our TypeDoc docs for source code level documentation. For a more in-depth guide, check out the React SDK guide in our docs.


Via npm:

npm install @dopt/react

Via Yarn:

yarn add @dopt/react

Via pnpm:

pnpm add @dopt/react


To configure the Dopt provider you will need:

  1. A blocks API key (generated in Dopt)
  2. The identifiers and version tags for the flows you want your end-users to experience
  3. A user identifier (user being an end-user you've identified to Dopt)



You can initialize Dopt in your app by integrating the <DoptProvider /> as follows:

import { DoptProvider } from '@dopt/react';
import Application from './application';

const rootElement = document.getElementById('root');
'new-user-onboarding': 2,
'plan-upsell': 4,
<Application />

Flow versions can be pegged to a fixed version by specifying a number. Alternately, using "uncommitted" will reference the uncommitted version in Dopt, and using "latest" will references the most recently created version in Dopt.

⚠️ Warning ⚠️: Using either "uncommitted" or "latest" for a flow version will cause updates made in Dopt to be reflected in the provider upon window reload without needing to update or deploy code.

Note: If userId is undefined, default objects with default states (e.g. all state values will default to false) will be returned from the associated hooks. Any subsequent updates to userId will trigger all hooks within the DoptProvider again and lead to fetching the appropriate states.

Flows and blocks

The SDK gives you access to two related objects: flows and blocks. Flows are entities representing the flow you designed in Dopt. Blocks are a subset of the blocks in that flow.

Flow objects available through the SDK are represented by the following type definition:

interface Flow {
readonly uid: string;
readonly sid: string;
readonly version: number;
readonly state: {
started: boolean;
finished: boolean;
stopped: boolean;
blocks: Block[];

The states of a flow are 1:1 with the actions you can perform on a flow. Flows have blocks, which are represented through the following type definition:

interface Block {
readonly uid: string;
readonly sid: string;
readonly version: number;
readonly state: {
active: boolean;
entered: boolean;
exited: boolean;
readonly transitioned: Record<string, boolean> | undefined;
field: <V extends string | number | boolean>(
name: string
) => V | null | undefined;

Unlike flows, the states of a block are not all 1:1 with actions you can perform. The entered and exited states do have an associated action, but the active state is special.

Key concept: The active state of a block is controlled by Dopt and represents where the currently initialized user (specified by the userId prop) is in the flow. As you or other actors perform actions that implicitly transition the user through the flow, the active state is updated.

Accessing flows and blocks

Now that you know what objects are available through the SDK, let's talk about how you access them.

By integrating the provider, all descendants of it can now access the flows configured in the flowVersions prop, and their associated blocks using the following React hooks and HOCs.

Using transitions

Our hooks and HOCs provide a transition function which you can use to progress and update the state of flows and blocks. The transition function accepts the path names you've defined on the flow canvas as inputs. These inputs will determine which paths the user will transition along.

This function is defined with a signature that explicitly does not return a value: (...inputs: string[]) => void | undefined. We do this because a transition may cause a flow and / or block transition along with other side effects. These changes will eventually propagate back to the client. Then, the client will reactively update and re-render the components which depend on these flow and block states. Calling an transition only means that at sometime in the future, the client's state will be updated.

Understanding loading status

We expose two hooks which enable you to wait for Dopt to initialize, both at the larger DoptProvider level and at the granular flow level. To wait for the entire DoptProvider to initialize, you can use useDoptInitialized. This hook returns a boolean which becomes true after the entire DoptProvider has finished loading.

If you would instead like to wait for specific flows, you can use the useFlowStatus hook. This hook returns a FlowStatus object ({ pending: boolean, failed: boolean }) - when the flow has finished loading, pending will be false. If the flow fails to load, then failed will be true.

Using React hooks

interface FlowIntentions {
start: (options?: { force?: boolean }) => void | undefined;
reset: (options?: { force?: boolean }) => void | undefined;
stop: () => void | undefined;
finish: () => void | undefined;
declare const useFlow: (id: string) => [flow: Flow, intent: FlowIntentions];
type BlockTransition = (...inputs: string[]) => void | undefined;
declare const useBlock: (
id: string
) => [block: Block, transition: BlockTransition];

Using React HOCs

We offer analogous functionality through higher order components for those who are limited by their version of React or prefer that pattern.

Example usage

Accessing blocks

Using the useBlock hook:

import { useBlock } from '@dopt/react';
import { Modal } from '@your-company/modal';

export function Application() {
const [block, transition] = useBlock<['complete']>(
return (
<Modal isOpen={}>
<h1>👏 Welcome to our app!</h1>
<p>This is your onboarding experience!</p>
<button onClick={() => transition('complete')}>Close me</button>

Accessing flows

Using the useFlow hook:

import { useFlow } from '@dopt/react';
import { Modal } from '@your-company/modal';

export function Application() {
const [flow, intent] = useFlow('new-user-onboarding');
return (
<Modal isOpen={flow.state.completed}>
<h1>👏 Your onboarding has finished!</h1>
<p>Want to reset? click the button below.</p>
<button onClick={intent.reset}>Reset onboarding</button>


The DoptProvider accepts a logLevel prop that allows you to set the minimum log level you would like to print into the console. This defaults to 'silent'.

logLevel="warn" // 'trace' | 'debug' | 'info' | 'warn' | 'error' | 'silent'
<Application />

Optimistic updates

The DoptProvider accepts an optimisticUpdates (boolean) prop that will optimistically update the state of a block when the complete intention method is called. This defaults to true. As of right now, only a step block's complete intention can be optimistically updated.
