@polkadot-apps/product-sdk

Product-side TypeScript SDK for apps running inside a Triangle User Agent.

Use this package when you are building the product or dApp that runs inside a host-provided webview or iframe and talks to the shell through window.host.

Install

npm install @polkadot-apps/product-sdk

Minimal example

import { data, files, media, mesh, navigateTo } from "@polkadot-apps/product-sdk";

await navigateTo("browse.dot");
await files.save({
  filename: "example.txt",
  bytes: new TextEncoder().encode("hello"),
});

This package is pure TypeScript. It does not depend on the host-side WASM runtime packages.

Positioning

@polkadot-apps/product-sdk is the recommended high-level product package for most new products in this ecosystem.

• use @polkadot-apps/product-sdk for the normal typed product-facing path
• use @polkadot/api-protocol if you need direct access to the canonical full contract or want to build a custom facade/transport layer
• use @polkadot-apps/productkit only when you intentionally want the narrow compatibility subset

Compatibility

• Node.js 18+ for local builds
• runs in guest/product code, not the host shell
• expects a compatible window.host bridge from the embedding Triangle User Agent
