I am trying to use a typescript-parser:
https://www.npmjs.com/package/typescript-parser
but I'm having difficulties with using the package properly.
I installed the package successfully using npm install; when I run npm list --depth=0 it shows up in the list.
Eventually, I tried running the following line of code that is suggested in the link attached above (using node command):
const parser = new TypescriptParser();
but the problem is that I get the following error:
const parser = new TypescriptParser();
^

Alternatively, I tried running this:
const TypescriptParser = require('typescript-parser');
const parser = new TypescriptParser();
yet I still get a (different) error:
const parser = new TypescriptParser();
^

It seems as if although the package was installed, it doesn't recognize the class TypescriptParser.
Any help would be much appreciated!
Try importing using:
import { TypescriptParser } from 'typescript-parser';
I tried the code below and it works for me :
index.js file
const parser = require('typescript-parser');
const parser = new TypescriptParser();
I run it with node index.js
This code works for me:
index.js file
const tp = require('typescript-parser');
const parser = new tp.TypescriptParser();

I have installed webppl-agents library (along with webppl and webppl-dp) and am trying to run the command line test, but I'm running into some trouble. It appears there is a dependency issue with jsdom from the npm paper module (1) (2) (3) (4), but I haven't been able to get a complete handle on the issue at this point.
Does anybody know what's going on here? Do I just need to use a newer version of paper?
PS C:\Users\user\.webppl\node_modules\webppl-agents> webppl --require webppl-dp --require . tests/tests.wppl

There has been some breaking changes recently. The following way of initializing jsodm, document and window fixed it for me:
import jsdom from 'jsdom';
const {JSDOM} = jsdom;
const {document} = (new JSDOM('<!doctype html><html><body></body></html>')).window;
global.document = document;
global.window = document.defaultView;
Hey guys I'm new to JS and Node.js and I'm having trouble setting up a webdriverio project using cucumber and PageObject. And every time I try to run a test this error happens:
ERROR: Cannot find module '../support/action/openWebsite'

This is the loginStepsDef.js file where the openWebSite is being called:
import openWebsite from '../support/action/openWebsite';
import LoginPage from '../pageobject/LoginPage/LoginPage';
module.exports = function given() {
this.Given(
/^I open salesforce login page$/,
openWebsite
);
this.When(
/^I set user "([^"]*)?" and password "([^"]*)?"$/, function(arg1,arg2) {
LoginPage.open();
LoginPage.username.setValue(arg1)
LoginPage.password.setValue(arg2)
});
this.And(
/^I click the login button$/,function(){
LoginPage.open();
LoginPage.submit();
});
}
Any idea what could be happening would be great. Do you need me to show something more let me know.
Try with this :
var openWebsite = require('../../support/action/openWebsite');
var LoginPage = require('../../pageobject/LoginPage/LoginPage');
I'm using node backend and am trying to connect to plaid.
My code:
var plaid = require('plaid');
var clientID = "bla";
var secretID = "bla";
var publicKey = "bla";
var client = new plaid.Client(
clientID,
secretID,
publicKey,
plaid.environments.sandbox
);
However I am getting this error in my console:
throw new Error('Invalid Plaid environment');
^

I have tried using each of these with no luck:
plaid.environments.sandbox
plaid.environments.development
plaid.environments.tartan
What's going on?
Ref: https://plaid.com/docs/quickstart/#accessing-item-data
UPDATE:
I've gotten this code below to work in another part of my app:
var plaidClient = new plaid.Client(clientID, secretID, plaid.environments.tartan);
However I am trying to use client.getTransactions() and it is required to have var plaidClient = new plaid.Client(clientID, secretID, publicID, plaid.environments.sandbox);
in order for client.getTransactions() to work.
UPDATE?
For some reason I had the wrong version of plaid installed. I needed to uninstall and reinstall to fix. Works now.
This question is not the same as Extended Errors do not have message or stack trace, which deals with es6 extends, but I'm using es5.
Here's my code
test.js
function FooError(message) {
this.stack = (new Error(message)).stack;
console.log('this.stack', this.stack);
console.log('new_error_stack', (new Error(message)).stack);
console.log('after');
}
FooError.prototype = new Error;
throw new FooError("foo");
This gives the following output : with node version 6.4 (node test.js)
this.stack Error

as you can see, the 'this.stack' doesn't show the same thing at all than the 'new_error_stack', eg, the this.stack shows the stack as if the error was thrown when the require was called. Also, the thrown stack is also "incorrect".
I took the code from https://stackoverflow.com/a/5251506/1993501 , and since I want to use instanceof FooError, I use the line FooError.prototype = new Error.
As you can see, the 'new_error_stack' gives the expected output, but I would have expected both values to be equal.
This has the effect that errors are not very useful for users of my library, see corresponding issue : https://github.com/open-xml-templating/docxtemplater/issues/245
What exactly is happening, and how can I prevent it and keep proper error types (eg being able to use instanceof) ?
I found a possible solution to your problem, but I'm not entirely sure it fixes all of your issues. I'm using Error.prototype instead of new Error (which is what you had). I found this solution from the first answer provided to this question: How do I create a custom Error in JavaScript?
I also changed your console.log lines to concatenate the two strings, as I was using alert() to display the output for testing purposes.
Kevin Hakanson goes over why you may or may not want to go with this solution in his answer. Here's the code to answer your question:
function FooError(message) {
this.stack = (new Error(message)).stack;
console.log('this.stack ' + this.stack);
console.log('new_error_stack ' + (new Error(message)).stack);
console.log('after');
}
FooError.prototype = Error.prototype;
throw new FooError("foo");
You may want to use a try/catch block with that last line.
