npm install @heyputer/puter.jsInclude Puter.js directly in your HTML via CDN in the <head> section:
<script src="https://js.puter.com/v2/"></script>import {puter} from '@heyputer/puter.js';
// or
import puter from '@heyputer/puter.js';
// or
import '@heyputer/puter.js'; // puter will be available globallyconst {puter} = require('@heyputer/puter.js');
// or
const puter = require('@heyputer/puter.js');
// or
require('@heyputer/puter.js'); // puter will be available globallyconst {init} = require("@heyputer/puter.js/src/init.cjs"); // NODE JS ONLY
// or
import {init} from "@heyputer/puter.js/src/init.cjs";
const puter = init(process.env.puterAuthToken); // uses your auth token
const puter2 = init(process.env.puterAuthToken2); // use some other auth tokenAfter importing, you can use the global puter object:
// Print a message
puter.print('Hello from Puter.js!');
// Chat with GPT-5 nano
puter.ai.chat('What color was Napoleon\'s white horse?').then(response => {
puter.print(response);
});By default puter.js uses the official Puter API and GUI origins. You can customize these origins by setting global variables before importing the SDK like so:
// For API origin
globalThis.PUTER_API_ORIGIN = 'https://custom-api.puter.com';
// For GUI origin
globalThis.PUTER_ORIGIN = 'https://custom-gui.puter.com';
import {puter} from '@heyputer/puter.js'; // or however you import it for your envApache-2.0
