Node.js Question

Unable to require node-wit

I had been using node-wit v3.3.2
Today, I wanted to update and use the latest version.

But I'm unable to import node-wit. Not sure why.
I simply copied the code given in their documentation.

'use strict'
var MY_TOKEN="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

const {Wit, log} = require('node-wit');

const client = new Wit({
accessToken: MY_TOKEN,
actions: {
send(request, response) {
return new Promise(function(resolve, reject) {
return resolve();
myAction({sessionId, context, text, entities}) {
console.log(Session ${sessionId} received ${text});
console.log(The current context is ${JSON.stringify(context)});
console.log(Wit extracted ${JSON.stringify(entities)});
return Promise.resolve(context);
logger: new log.Logger(log.DEBUG) // optional

The terminal shows this:

const {Wit, log} = require('node-wit');

SyntaxError: Unexpected token {

Answer Source

Could be the node version you are using. You'll need to use the flag --harmony_destructuring when using a lower version.

Taken from:

# Node.js <= 6.x.x, add the flag --harmony_destructuring
node --harmony_destructuring examples/basic.js <MY_TOKEN>
# Node.js >= v6.x.x
node examples/basic.js <MY_TOKEN>
