* fix(events): bill reached deliveries only, bound dispatch reads, seal cursors - A broadcast socket copy is billed only when a connection for its holder exists on this node, anywhere in this region (connection count) or, for a durable row, in a region presence names. Without peers it bills as before. - Compiled match filters are held in a bounded LRU with a TTL, and dropped when another process reports a subscription ended. - GET /events/fetch reads the continuation from `cursor`, falling back to `after`. - Cursors from /events/fetch, /events/subscriptions and /events/kv-handles are encrypted with sealCursor/openCursor; plain cursors still read. - A durable subscribe counts again after its insert and removes its own row when over the cap; the generation bump for that removal is published. - Subscribe checks access before reading the anchor's owner, and an anchor gone in between answers with the subject the caller sent. - Dispatch reads at most the rows per token routing can use, scanning large token hashes; a removal still settles every row on the removed anchor. - puter.events.unsubscribe() stops routing after the server ends the subscription or reports it gone; fetch() accepts `cursor`. * fix(events): forward kv values only to regions with rows that ask - A region counts its session rows asking for kv values per token and announces the token's value variant (`v#<token>`) over the existing `watch` item on the first such row, withdrawing it with the last. Add, remove, reap, reanchor and refresh all keep it, reading `includeValue` off the row as it is dropped. - A kv write reads the value variants alongside the watch index and attaches the value only to forwards bound for a region that announced one. * fix(pagination): seal id-keyed cursors on every list endpoint Apps, subdomains, workers, team (members, directory, teams, audit, own audit), shares (inbound, outbound), the user-to-user permission audit and readdir/descendant listings now hand out cursors sealed with sealCursor and read them with openCursor, so a cursor no longer carries a row id. Plain cursors issued before still read. * test(events): pass socket ids to noteConnect in the billing tests

Puter.js gives you auth, cloud storage, database, AI, and more through a single JavaScript library. It is the go-to backend for AI-generated apps.
There is nothing to configure, no API keys, no infrastructure to set up, whether you write the code yourself or have your AI tool do it. Tools like Claude Code, Codex, OpenCode, Lovable, and Replit can generate complete, production-ready apps in a single shot with fewer AI tokens.

Usage
Browser
ES Modules
import {puter} from '@heyputer/puter.js';
// or
import puter from '@heyputer/puter.js';
// or
import '@heyputer/puter.js'; // puter will be available globally
CommonJS
const {puter} = require('@heyputer/puter.js');
// or
const puter = require('@heyputer/puter.js');
// or
require('@heyputer/puter.js'); // puter will be available globally
Node.js (with Auth Token)
const {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 token
Node.js (with Auth Token + Web Login)
const {init, getAuthToken} = require("@heyputer/puter.js/src/init.cjs");
// or
import {init, getAuthToken} from "@heyputer/puter.js/src/init.cjs";
const authToken = await getAuthToken(); // performs browser based auth and retrieves token (requires browser)
const puter = init(authToken); // uses your auth token
Usage Example
After 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);
});
Starter Templates
You can also use one of the following templates:
- Client-side projects: Angular, React, Next.js, Vue.js, Vanilla.js
- Node.js + Express: Node.js + Express template
Setting Custom Origins
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 env
