## @ledgerhq/hw-transport-node-speculos-http A transport for Nano simulator using its HTTP API. [GitHub](https://github.com/LedgerHQ/ledger-live/), [Ledger Devs Discord](https://developers.ledger.com/discord-pro), [Developer Portal](https://developers.ledger.com/) ### Getting started * Install * Make sure to have a speculos running with an API port (default port is 5000). ```js import SpeculosTransport from "@ledgerhq/hw-transport-node-speculos-http"; async function exampleSimple() { const transport = await SpeculosTransport.open(); const res = await transport.send(0xE0, 0x01, 0x00, 0x00); } async function exampleAdvanced() { const transport = await SpeculosTransport.open({ baseURL: "http://localhost:5000" }); transport.eventStream.once("data", { // we will click right when the display changes transport.button("right"); }); // we can also use eventStream.on and match the data buffer with the expected display before taking action // derivate btc address and ask for device verification const res = await transport.send(0xE0, 0x40, 0x01, 0x00, Buffer.from("058000002c8000000080000000000000000000000f")); } ``` ## API #### Table of Contents * [SpeculosHttpTransport](#speculoshttptransport) * [Parameters](#parameters) * [Examples](#examples) * [button](#button) * [Parameters](#parameters-1) ### SpeculosHttpTransport **Extends Transport** Speculos TCP transport implementation #### Parameters * `instance` **AxiosInstance** * `opts` **SpeculosHttpTransportOpts** #### Examples ```javascript import SpeculosHttpTransport from "@ledgerhq/hw-transport-node-speculos-http"; const transport = await SpeculosHttpTransport.open(); const res = await transport.send(0xE0, 0x01, 0, 0); ``` #### button Press and release button buttons available: left, right, both ##### Parameters * `but` **any** Returns **[Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\**
