napi-bindings

node-napi-bindings

Simple Node bindings for the Nymi API (NAPI) 4.0.

Please refer to the official Nymi Github or SDK Documentation for details.

Support

Currently the bindings are only support Windows. When macOS Sierra is officially supported i will give it a go to support it.

Feel free to participate and create a pull request if you need Mac support sooner.

Install

npm i napi-bindings

Prerequisite

Create a file in the root directory of your project named config.json with the following content.

{
    "neaName" : "sample",
    "sigAlgorithm" : "NIST256P",
    "automaticFirmwareVersion" : false
}

Example

This example will initialize the NAPI, request info about all provisioned Nymi Bands and print the result. The example makes the assumption you are using the Nymulator on your local machine on default port 9088.

const napi = require('napi-bindings');

try {
    let init, put, get;

    init = napi.jsonNapiConfigureD('.', napi.LogLevel.NORMAL, 9088, '127.0.0.1');

    console.assert(init === napi.ConfigOutcome.OKAY, 'INIT: %s', Object.keys(napi.ConfigOutcome)[init]);

    put = napi.jsonNapiPutD(JSON.stringify({path: 'info/get', exchange: 'provisions'}));

    console.assert(put === napi.JsonPutOutcome.OKAY, 'PUT: %s', Object.keys(napi.JsonPutOutcome)[put]);

    get = napi.jsonNapiGetD();

    console.assert(get.outcome === napi.JsonGetOutcome.OKAY, 'GET: %s', Object.keys(napi.JsonGetOutcome)[get]);

    console.log(JSON.parse(get.message));
} catch(err) {
    console.error(err.message);
} finally {
    napi.jsonNapiTerminateD();
}
