JsSignatureProvider is not a constructor node js issue

[ambrish-dev]

I am using below code in node js but it is showing JsSignatureProvider is not a constructor . I also want to know how to generate defaultPrivateKey in node js for EOS

   const { Api, JsonRpc, RpcError } = require('eosjs');
   const  { JsSignatureProvider } =  require('eosjs/dist/eosjs-jssig');  // development only
const defaultPrivateKey = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" // useraaaaaaaa

const privateKeys = [defaultPrivateKey];

const signatureProvider = new JsSignatureProvider(privateKeys);
const rpc = new JsonRpc('http://127.0.0.1:8888');
const api = new Api({ rpc, signatureProvider });

Please provide solution . Thanks

I found solution const JsSignatureProvider = require('eosjs/dist/eosjs-jssig').default;

The above code and solution doesn't work for latest eosjs. Here is the complete code that works:

const { Api, JsonRpc, RpcError } = require('eosjs'); const { JsSignatureProvider } = require('eosjs/dist/eosjs-jssig'); // development only const fetch = require('node-fetch'); // node only; not needed in browsers const { TextEncoder, TextDecoder } = require('util');

const defaultPrivateKey = "XXX"; const privateKeys = [defaultPrivateKey]; const signatureProvider = new JsSignatureProvider(privateKeys);

const rpc = new JsonRpc('http://api.eostribe.io/', { fetch });

const api = new Api({ rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder() });

(async () => { const result = await api.transact({ actions: [{ account: 'eosio.token', name: 'transfer', authorization: [{ actor: 'sendraccount', permission: 'active', }], data: { from: 'sendraccount', to: 'receiveracct', quantity: '0.0001 EOS', memo: '', }, }] }, { blocksBehind: 3, expireSeconds: 30, }); console.dir(result); })();
