What are react-plaid-link's main functionalities?

Initialize Plaid Link

This code demonstrates how to initialize Plaid Link in a React application. The `PlaidLink` component is configured with necessary props like `clientName`, `env`, `product`, `publicKey`, and `onSuccess` callback.

import React from 'react';
import { PlaidLink } from 'react-plaid-link';

const App = () => {
  const onSuccess = (public_token, metadata) => {
    console.log('Public Token: ', public_token);
    console.log('Metadata: ', metadata);
  };

  return (
    <PlaidLink
      clientName="Your App Name"
      env="sandbox"
      product={['auth', 'transactions']}
      publicKey="your_public_key"
      onSuccess={onSuccess}
    >
      Connect a bank account
    </PlaidLink>
  );
};

export default App;

Handle onExit Callback

This code demonstrates how to handle the `onExit` callback, which is triggered when the user exits the Plaid Link flow. The `onExit` callback provides error information and metadata.

import React from 'react';
import { PlaidLink } from 'react-plaid-link';

const App = () => {
  const onExit = (error, metadata) => {
    console.log('Error: ', error);
    console.log('Metadata: ', metadata);
  };

  return (
    <PlaidLink
      clientName="Your App Name"
      env="sandbox"
      product={['auth', 'transactions']}
      publicKey="your_public_key"
      onExit={onExit}
    >
      Connect a bank account
    </PlaidLink>
  );
};

export default App;

Handle onEvent Callback

This code demonstrates how to handle the `onEvent` callback, which is triggered for various events during the Plaid Link flow. The `onEvent` callback provides the event name and metadata.

import React from 'react';
import { PlaidLink } from 'react-plaid-link';

const App = () => {
  const onEvent = (eventName, metadata) => {
    console.log('Event Name: ', eventName);
    console.log('Metadata: ', metadata);
  };

  return (
    <PlaidLink
      clientName="Your App Name"
      env="sandbox"
      product={['auth', 'transactions']}
      publicKey="your_public_key"
      onEvent={onEvent}
    >
      Connect a bank account
    </PlaidLink>
  );
};

export default App;
