From 19 to 20

Compatibility

Browser support: We support Safari mobile and desktop 16, Chrome 109 and Firefox 106. Browsers older than this may still be able to use our SDK, but may require additional transpile and polyfills.
No polyfills are included since all APIs used are also supported in the versions supported.
Custom themes require support for color-mix CSS function. A compatibility helper is available if you are targeting older browsers.

Step by step guide

Upgrade packages

Upgrade @stytch/react and remove @stytch/vanilla-js: vanilla-js is now included in @stytch/react and no longer a peer dependency.

package.json

"@stytch/react": "^19.0.0", 
"@stytch/vanilla-js": "^5.0.0", 
"@stytch/react": "^20.0.0", 

Run npm, yarn or pnpm to install the new version.

Update imports

Copy all imports from @stytch/vanilla-js to @stytch/react. The b2b/ui and b2b/headless imports have also been merged into the main b2b import.

import React from 'react';
import { StytchB2B, StytchB2BProvider } from '@stytch/react/b2b'; 
import { createStytchB2BUIClient } from '@stytch/react/b2b/ui'; 
import { AuthFlowType, B2BOAuthProviders, B2BProducts } from '@stytch/vanilla-js/b2b'; 
import { 
  AuthFlowType,
  B2BOAuthProviders,
  B2BProducts,
  StytchB2B,
  StytchB2BProvider,
  createStytchB2BUIClient,
} from '@stytch/react/b2b';

Update products configuration

If config.products are specified as strings, update them to use B2BProducts instead:

import { B2BProducts } from '@stytch/react/b2b'; 

const config = {
  products: ['oauth', 'eml'], 
  products: [B2BProducts.oauth, B2BProducts.emailMagicLinks], 
};

Update styles to presentation

The new presentation property now controls theming and styling options. This differs from the previous style property in that it configures tokens affecting many elements rather than properties on specific elements.We have provided a migration helper function. In development mode this function will also print out warnings about properties that could not be migrated.

import { styleToTheme } from '@stytch/react/compat'; 

const config = {
  style: { ... }, 
  // This will also print out the recommended migrated config
  // which should replace this in production
  theme: styleToTheme({ ... }),
};

For a full list of supported properties, see reference documentation for presentation.

`presentation.theme`

Controls CSS styling. Each token corresponds to some CSS properties, so each value should be a CSS value. You can also provide an array of [lightTheme, darkTheme] which will automatically switch between the two depending on the user's OS color scheme.

More styling changes

These changes are unlikely to cause issues.

Component size

Stytch UI component now use max-width rather than width to make it more flexible. This means the component may render at a size smaller than expected if it is placed in a flexbox or grid. To restore previous behavior, wrap it in a div with your desired width.

<div style={{ width: '400px' }}>
  <StytchB2B />
</div>

Style isolation and injection

The SDK now injects styles into the head element as a style tag. The component styling is also slightly less aggressive, so global styles may affect internal styling differently. If you would like complete style isolation, we recommend enabling shadow DOM.

const presentation = {
  options: {
    enableShadowDOM: true,
  },
};

Element IDs

Some element IDs have been removed. To restore them, use `presentation.options.buttonId`. We do not recommend using the IDs to modify Stytch UI component styles or DOM.

const presentation = {
  options: {
    buttonId: true, // Or set to a string to add a suffix to make ID unique
  },
};

Update customized strings

If you use string customization, check if you need to update these strings:

Update deprecated imports

The following are deprecated and should be updated.

createStytchB2BUIClient → createStytchB2BClient
createStytchB2BHeadlessClient → createStytchB2BClient
StytchB2BUIClient → StytchB2BClient
StytchB2BHeadlessClient → StytchB2BClient

Test your changes

We recommend running through every auth method used to make sure the new theme looks correct in context. You should also take note of errors or warnings in the browser console.
