Installation

Umbrella package

Install the unified entry point:


pnpm add @parity/product-sdk

This re-exports every module and provides createApp(). For most applications, this is all you need.

Install only what you use:


pnpm add @parity/product-sdk-chain-client @parity/product-sdk-tx

Node.js ≥ 20
Module format: ESM only. The SDK does not ship CommonJS builds.
TypeScript ≥ 5.0 if consuming types (strict mode supported)
Runtime host: the umbrella @parity/product-sdk requires a compatible host (Polkadot Desktop, Polkadot Mobile, or a web host like dot.li ). For local development, @parity/host-api-test-sdk embeds a test host in your dev server.
