I'm using ubuntu 16.04 on vagrant to run this node.js.
node version is v6.2.2.
this is my code. i try to browsing for the solution using the keyword "SyntaxError: Unexpected identifier" but no luck.
function SignalFire(ID, startingLogs) {
this.fireID = ID;
this.logsLeft = startingLogs;
}
SignalFire.prototype = {
addLogs: function(numLogs) {
this.logsLeft += numLogs;
}
lightFire: function() {
console.log("Whooosh!");
}
}
this is the error i got:
/vagrant/inheritance.js:11
lightFire: function() {
^^^^^^^^^

let foo: number = 23;
console.log( foo );
// let foo: number = 23;

You have two options:
First compile it to plain JS with tsc myfile.ts and run the JS file with node myfile.js.
Or npm install ts-node which lets you run TS files like you would run JS files: ts-node myfile.ts
I'm getting the following error while running the below. The issue is with the unexpected toke "=". Due to which I'm getting the error.

Nodejs version 4.8.3
function* (dir,relativeDir, ignoreBasenames = new Set() uses default parameters.
Node.js 4.8.3 does not support default parameters for functions. You will need to use at least Node.js 6.

I'm using Ubuntu server 18.04.
Every time I try to use NPM it crashes and shows the following exception:

Does anybody has any idea of what could be wrong?
I'm getting an error when declaring a class:
// This is all on my test1.ts file content
class WDesign {
wModel: string;
wQuer: string;
}
let logWDesign = (wd : WDesign) => {
console.log(wd.wModel + " " + wd.wQuer);
}
let wd1 : WDesign;
wd1.wModel = "SDS-9985";
wd1.wQuer = "escarni";
logWDesign(wd1);
Then, to show on Node command prompt:
>node test1.ts
I get the following:
[filePath].test1.ts:3
wModel: string;

Typescript ver 3.1.3
Node ver. 8.12.0
Visual Studio Code 1.28.2
You firstly have to transpile the .ts file .js by simply running the command
tsc
node test1.js
This will generate javascript corresponding to your typescript files. Node cannot directly understand typescript. You have to give it javascript code.
You can use typescript-node-starter code provided by Typescript here to save configuration hustle.
Post comments if further help is required.
I tried to install Brwoswershots (https://github.com/spatie/browsershot) and I did this exactly by following the instructions on github.
Installing NodeJS and npm via yum
Installing browswershoots via composer: composer require
satie/browsershot
crated a file with
use Spatie\Browsershot\Browsershot;
$pathToImage="img/testasdf.png";
// an image will be saved
Browsershot::url('https://example.com')
->setScreenshotType('jpeg', 100)
->save($pathToImage);
It is on http://textblob.com/browsershots.php and brings the error.

I could solve this by downgrading to boxshot v2, witch works without puppeteer and so its not a fix, but working for me.
