This is a JS SDK is intended for browser based applications that need to interact with the Three0 Service Suite. It is not intended yet for Node.js applications. The SDK is currently in alpha stage development and is not yet ready for production use.
npm i --save @three0dev/js-sdk
- Import Three0 and prepare configuration
import { init } from '@three0dev/js-sdk'
const config = {
"contractName": "myTestContract",
"projectId": "myTestProject",
"chainType": "NEAR_TESTNET"
}
- Initialize SDK
import React from 'react'
import { createRoot } from 'react-dom/client'
import App from './App'
init(config).then(() => {
const container = document.querySelector('#root')
const root = createRoot(container)
root.render(<App />)
}).catch(console.error)
import React from 'react'
import { render } from 'react-dom'
import App from './App'
init(env.config)
.then(() => {
render(
<App />,
document.getElementById("root")
);
}).catch(console.error)
import { createApp } from 'vue';
import App from './App.vue';
init(config)
.then(() => {
const app = createApp(App);
app.use(store);
app.use(router);
app.mount('#app');
}).catch(console.error)
