Does not provide USB events. ## API #### Table of Contents * [createHIDframing](#createhidframing) * [Parameters](#parameters) * [makeBlocks](#makeblocks) * [Parameters](#parameters-1) * [reduceResponse](#reduceresponse) * [Parameters](#parameters-2) * [getReducedResult](#getreducedresult) * [Parameters](#parameters-3) * [TransportNodeHidNoEvents](#transportnodehidnoevents) * [Parameters](#parameters-4) * [Examples](#examples) * [exchange](#exchange) * [Parameters](#parameters-5) * [close](#close) * [isSupported](#issupported) * [list](#list) * [listen](#listen) * [Parameters](#parameters-6) * [open](#open) * [Parameters](#parameters-7) ### createHIDframing Object to handle HID frames (encoding and decoding) #### Parameters * `channel` **[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** * `packetSize` **[number](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Number)** The HID protocol packet size in bytes (usually 64) ### makeBlocks Frames/encodes an APDU message into HID USB packets/frames #### Parameters * `apdu` **[Buffer](https://nodejs.org/api/buffer.html)** The APDU message to send, in a Buffer containing \[cla, ins, p1, p2, data length, data(if not empty)] Returns **[Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Array)<[Uint8Array](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Uint8Array)<[ArrayBuffer](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer)>>** an array of HID USB frames ready to be sent ### reduceResponse Reduces HID USB packets/frames to one response. #### Parameters * `acc` **ResponseAcc** The value resulting from (accumulating) the previous call of reduceResponse. On first call initialized to `initialAcc`. The accumulator enables handling multi-frames messages. * `chunk` **[Buffer](https://nodejs.org/api/buffer.html)** Current chunk to reduce into accumulator Returns **ResponseAcc** An accumulator value updated with the current chunk ### getReducedResult Returns the response message that has been reduced from the HID USB frames #### Parameters * `acc` **ResponseAcc** The accumulator Returns **([Buffer](https://nodejs.org/api/buffer.html) | null | [undefined](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/undefined))** A Buffer containing the cleaned response message, or null if no response message, or undefined if the accumulator is incorrect (message length is not valid) ### TransportNodeHidNoEvents **Extends Transport** node-hid Transport minimal implementation #### Parameters * `device` **HID.HID** * `$1` **{context: TraceContext?, logType: LogType?}** (optional, default `{}`) * `$1.context` * `$1.logType` #### Examples ```javascript import TransportNodeHid from "@ledgerhq/hw-transport-node-hid-noevents"; ... TransportNodeHid.create().then(transport => ...) ``` #### exchange Exchange with the device using APDU protocol. ##### Parameters * `apdu` **[Buffer](https://nodejs.org/api/buffer.html)** Returns **[Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)<[Buffer](https://nodejs.org/api/buffer.html)>** a promise of apdu response #### close release the USB device. Returns **[Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\** #### isSupported Returns **[Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)<[boolean](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Boolean)>** #### list Returns **[Promise](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/Promise)\** #### listen ##### Parameters * `observer` **Observer\>** Returns **Subscription** #### open if path="" is not provided, the library will take the first device ##### Parameters * `path` **([string](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/String) | null | [undefined](https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/undefined))** --- _Source: https://npm.io/package/@ledgerhq/hw-transport-node-hid-noevents · Machine-readable twin of the npm.io package page.
