"Unexpected token {" when using npx babel-node - node.js

Here is my script test.js:
import 'jsdom-global/register';
import 'canvas';
console.log('done');
And here is my package.json:
{
"name": "test-jsdom",
"description": "Test",
"version": "0.1.0",
"author": "anthony#me.com",
"dependencies": {
"canvas": "^1.6.7"
},
"devDependencies": {
"babel-cli": "^6.26.0",
"babel-preset-env": "^1.6.1",
"babel-preset-stage-0": "^6.24.1",
"jsdom": "^11.3.0",
"jsdom-global": "^3.0.2"
}
}
When I run npx babel-node test.js, I encountered this error
/Users/antkong/test/node_modules/jsdom/lib/api.js:10
const { URL } = require("whatwg-url");
^
SyntaxError: Unexpected token {

And it is my .babelrc file
{
"presets": ["env", "stage-0"]
}
It seems to me babel-node cannot handle es6 syntax in the dependent js file. I expect babel-node to be able to load and compile all dependency on the fly. How can I fix this problem?
Version info:
$ node --version
v4.8.6
$ npm --version
2.15.11

Should use more up to date version of node.
I use nvm to switch node to version 8.7.0 and the issue is fixed.

Can't deploy smart contract application to Heroku

My application is built with Truffle and React, and I am getting an error when I try to deploy to Heroku. In my local machine all works perfectly, but when I try to deploy:

-----> Build failed
I see some errors before the build starts, when installing the dependencies. I have the impression something is not OK with truffle when installing it on Heroku, but I am not sure about it. After it, it crashes when doing the build.
I must remark that I was able to run npm run build on my local machine with no errors.
This is my package.json:

Make sure you are not including the node_modules folder while deploying. If that is not the case, try setting config vars.
So basically when heroku tries to build your project it run in to an error.
/tmp/build_e68c9473/node_modules/fs-extra/lib/mkdirs/make-dir.js:85
} catch {
^
SyntaxError: Unexpected token {
The most probable cause of this error is that the syntax for try/catch block is as follows:
try {
...
} catch (error) {
...
}
Try to add (error) between the catch and the { everywhere you have try/catch block.

NodeJS: Module did not self-register

I am trying IBM Watson's Speech to Text API. While running my NodeJS app I get this.
I am using line-in package for streaming the input audio data in output, in addition to IBM Watson's SpeechToText package.
I tried removing node_modules and $ npm install and $ npm rebuild. Nothing worked.

https://stackoverflow.com/questions/27431187/cannot-find-module-lodash/36618374
Also I see the below warning message:
Problems loading reference 'https://schemastore.azurewebsites.net/schemas/json/package.json': Unable to load schema from 'https://schemastore.azurewebsites.net/schemas/json/package.json': Unable to connect to https://schemastore.azurewebsites.net/schemas/json/package.json. Error: self signed certificate in certificate chain
Can anyone help me to fix this issue?
The package name should be lodash, not loadash.
After you correct that in packages.json you need to execute npm install.

Webpack Breaks Mocha in Node.js App

I have a node.js app that uses Mocha and Expect for testing. All the tests work great, until I installed webpack for react. Now when I run "npm test" I get the following error:

I'm not sure if webpack.config is necessary to post, but just in case:
module.exports = {

output: {
path: __dirname,
filename: './public/bundle.js'
},
resolve: {
root: __dirname,
alias: {
AdminUserTable: 'app/components/AdminUserTable.jsx'
},
extensions: ['', '.js', '.jsx']
},
module: {

loader: 'babel-loader',
query: {
presets: ['react', 'es2015']
},
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/
}
]
}
};
Running the command npm test works great when I uninstall webpack, I'm not sure why It's breaking mocha.
Your package.json is missing should as a dependency.
Install it via;
npm install --save-dev should
Also I would recommend you look into chai which in my opinion provides a slightly different API.
should is an expressive, readable, framework-agnostic assertion library. The main goals of this library are to be expressive and to be helpful. It keeps your test code clean, and your error messages helpful.
By default (when you require('should')) should extends the Object.prototype with a single non-enumerable getter that allows you to express how that object should behave. It also returns itself when required with require.
It is also possible to use should.js without getter (it will not even try to extend Object.prototype), just require('should/as-function'). Or if you already use version that auto add getter, you can call .noConflict function.
Results of (something).should getter and should(something) in most situations are the same
Better u install node dependency should with npm as below
npm install --save should
should-reference

I've come back to this recently and have managed to get it working by using the community built Node v0.12 cartridge. If you are having similar issues I'd recommend ditching the "official" Node v0.1 app cartridge and trying again.
Sweet - free hosting of my node app! :D
