I would like to use npm talib module within a meteorjs application.I followed the instruction here and I added this to the packages.json file:
{
"talib" : "0.6.0"
}
After running meteor the module talib.node is there in the node_modules/talib/build/Release/ folder.
Then I wrote the following:
if (Meteor.isServer) {
var Talib = Meteor.npmRequire('talib');
var talib = new Talib();
}
The Talib object is created and can be logged, like this:
{ version: '0.6.0',
functions:
[ { name: 'ADD',
group: 'Math Operators',
...
}
],
functionUnstIds:
{ TA_FUNC_UNST_ADX: 0,
TA_FUNC_UNST_ADXR: 1,
...
}
}
The line var talib = new Talib() gives instead this error:
TypeError: object is not a function
What I am doing wrong?

The Question
According to documentation: https://docs.aws.amazon.com/cdk/api/latest/docs/aws-cloudfront-readme.html#lambdaedge no role needs to be provided.
How to provide the required role?

I'm working with NextJS and using react-data-export plugin to generate xls files.
in the description it says :
This library uses file-saver and xlsx and using
json-loader will do the magic for you.
///webpack.config.js
vendor: [
.....
'xlsx',
'file-saver'
],
.....
node: {fs: 'empty'},
externals: [
{'./cptable': 'var cptable'},
{'./jszip': 'jszip'}
]
but I have no idea how to implement it and got error like this :
The static directory has been deprecated in favor of the public directory. https://err.sh/vercel/next.js/static-dir-deprecated

Could not find files for /menu_accounting/ReportGross in .next/build-manifest.json
I had the same problem, the solution for me was this:
Install this packages (if you installed, ignored this)
npm install file-saver --save
npm install xlsx
npm install --save-dev json-loader
Add this to your nextjs.config.js
const path = require('path')
module.exports = {
...
//Add this lines
webpack: (config, { isServer }) => {
// Fixes npm packages that depend on `fs` module
if (!isServer) {
config.node = {
fs: 'empty'
}
}
return config
}
}
I'm trying to use CanvasJS inside my project. I'm using RequireJS to manage the modules, and have this in the main script:
define(['domReady',"canvasjs","common-functions"], function(domReady,CanvasJS) {
domReady(function () {
window.CanvasJS = CanvasJS;
init_page_select();
});
});
This is what I have in my requireJS config file for the path:
"paths": {
// other stuff here
"canvasjs": "node_modules/canvasjs/dist/canvasjs.min"
},
I can see the canvasjs.min.js file being grabbed fine - but then I get this weird error:

I'm invoking it with:
var chart = new CanvasJS.Chart("thegraph",
{
title:{
text: impressionText
},
theme: "theme2",
axisX: {
valueFormatString: "MMM-DD-YYYY",
labelAngle: -50
},
axisY:{
valueFormatString: "#0",
title: impressionText
},
data: [
{
type: "line",
showInLegend: true,
legendText: legendText,
dataPoints: dataPoints
}
]
});
chart.render();
Interestingly, if I tell it to load canvasjs.js instead of canvasjs.min.js, I get another error:
ReferenceError: intToHexColorString is not defined[Learn More]
OK so the problem seemed to be my version. For some reason "npm install canvasjs" was installing 1.8.1, but 2.2 was out. As per their request, I updated it to 2.2 and it sorted the problem. It seems weird npm is running such an outdated version though
I am trying to install slack node library, but not able to do it successfully.

But when i run gulp command on shell i am getting following error:-

I am getting this error in the command line when I run app.js on node:
FATAL ERROR: v8::HandleScope::CreateHandle() Cannot create a handle without a HandleScope
Abort trap: 6
This is what am app.js looks like:
var phantom = require('x-ray-phantom');
var Xray = require('x-ray');
var fs = require('fs');
x = new Xray().driver(phantom());;
x('http://www.bbc.co.uk/news', '.most-popular__list panel-read li', [{
content: ''
}])(function (err, results) {
fs.writeFile('results.json', JSON.stringify(results, null, '\t'));
})
My package.json
{
...
"dependencies": {
"phantomjs": "^1.9.19",
"x-ray": "^2.0.2",
"x-ray-phantom": "^1.0.1"
}
...
}
My node version is v5.3.0, Npm version is 3.3.12, Phantomjs version is 1.9.8. I am on a Mac El Capitan 10.11.1
Check if this works:
x = new Xray().driver(phantom({
dnodeOpts: {
weak: false
}
}));
I use phantom instead of x-ray-phantom and I encountered the same issue. It appears that the module node-weak is broken (https://github.com/TooTallNate/node-weak/issues/65), and bypassing this module as this link suggests has solved my case.
