Svelte + Vite
A user-friendly guide to integrate the Para Modal (React-based) into your Svelte application powered by Vite.
This guide shows you how to integrate the Para Modal—which is React-based—within a Svelte application that is powered by Vite.
If you haven’t already you can create a new Svelte project with Vite by following the official Vite docs. Alternatively, you can fork our minimal starter that already includes the Para Modal setup: Para Svelte + Vite Starter.
Although mixing React and Svelte is unusual, we can do so via svelte-preprocess-react. If you prefer to build your own custom UI, you can also use @getpara/web-sdk
directly.
Prerequisites
To use Para, you need an API key. This key authenticates your requests to Para services and is essential for integration.
Don’t have an API key yet? Request access to the Developer Portal to create API keys, manage billing, teams, and more.
Installing Dependencies
First, install both the Para React SDK and React dependencies:
Setting Up the Svelte Preprocessor and Vite Polyfills
Svelte Preprocessor for React
You must configure your Svelte app to accept React components. For that, install and configure
svelte-preprocess-react
:
Then add it to your svelte.config.js
:
Vite Polyfills
Like other React-based setups, you may need Node.js polyfills for features like crypto
, buffer
, and stream
.
Install vite-plugin-node-polyfills
:
Then configure it in vite.config.js
or vite.config.ts
:
Setting Up the Para SDK
Now that you’ve installed the necessary dependencies, let’s set up the Para SDK in your Svelte application. This involves creating a client instance and integrating the Para Modal.
Creating a Para Client Instance
Much like in React or Vue, you’ll need a Para client instance. Keep it in a dedicated file (e.g., client/para.ts
):
Para offers two hosted environments: Environment.BETA
(alias Environment.DEVELOPMENT
) for testing, and
Environment.PROD
(alias Environment.PRODUCTION
) for live use. Select the environment that matches your current
development phase.
Integrating the Para Modal in Svelte
With svelte-preprocess-react
, you can directly use React components in Svelte:
Beta Testing Credentials In the BETA
Environment, you can use any email ending in @test.getpara.com
(like
dev@test.getpara.com) or US phone numbers (+1) in the format (area code)-555-xxxx
(like (425)-555-1234). Any OTP
code will work for verification with these test credentials. These credentials are for beta testing only. You can
delete test users anytime in the beta developer console to free up user slots.
When you click Open Para Modal, the React-based Para Modal will appear inside your Svelte application.
Customizing the Para Modal
Just like in React, you can provide any additional props to the <ParaModal>
component. For example, customizing
theming:
If You Don’t Want to Use the React Modal
You can instead use the @getpara/web-sdk to build your own Svelte-based UI. This avoids the React modal entirely, but you’ll need to manually implement authentication, wallet management, etc. For details on how to do this, refer to the
Customize Para guide.

Next Steps
After integrating Para, you can explore other features and integrations to enhance your Para experience. Here are some resources to help you get started:
