Installation

SDK can be connected in two ways:

• as an npm package (ESM/CJS) for Node.js and bundlers
• as a UMD bundle in the browser via a <script> tag

Node.js

Requirement

Supported versions ^18.0.0 || ^20.0.0 || >=22.0.0

npm

npm install @flowlu/miniapp-jssdk

yarn

yarn add @flowlu/miniapp-jssdk

Import the library into your project:

ESM

import { App, Frame, Toast } from '@flowlu/miniapp-jssdk'

CJS

const { App, Frame, Toast } = require('@flowlu/miniapp-jssdk')

UMD

Via CDN

Include the library directly via CDN — add a <script> tag with the latest version to your HTML file:

<script src="https://unpkg.com/@flowlu/miniapp-jssdk@latest/dist/miniapp-jssdk.min.js"></script>

Local import

If you prefer to keep the library file in your project, first download the library from the CDN and add it to your project.

Then include the file in your HTML:

<script src="/path/to/miniapp-jssdk.min.js"></script>

After including the script, the SDK is available via the global variable FlowluMiniApp:

const App = window.FlowluMiniApp;
const Frame = App.Frame;
const Toast = Frame.Toast;
