I'm trying to configure mocha to run the tests instead of running manually using the command:
node_modules\.bin\mocha -w
I get the error as below.
D:\Downloads\Bluemix\dw0015a\dw0015a\node_modules\mocha\lib\utils.js:626
throw new Error("cannot resolve path (or pattern) '" + path + "'");

I am able to get a behavior similar to what you report is to have the w option preceded by an "en dash" character (Unicode U+2013) rather than a minus character. Like this:
$ mocha –w
/home/x/local/lib/node_modules/mocha/lib/utils.js:626
throw new Error("cannot resolve path (or pattern) '" + path + "'");
^
Error: cannot resolve path (or pattern) '–w'
at Object.lookupFiles (/home/x/local/lib/node_modules/mocha/lib/utils.js:626:15)
[... etc ...]
Make sure you are using the minus character (hex value 0x2d).

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 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;

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.

i followed this project link in order to build mine
have no idea why, i read deeply the code and it seems it should be okay. could someone help me ?
Here's the server I'm using, https://www.npmjs.com/package/live-server. However, when I try to use ~/.live-server.json as the configuration file, I always fail... Here's what I have in the file, and it's very simple.
{
port: "8001"
}
Then I have this error when I run live-server
undefined:2

I don't know why this is happening.
Property names in JSON must be quoted (JSON is not JavaScript):
{
"port": "8001"
}
It should be:
{
"port": 8001
}
Add explanation: well, in JSON, name should always double quoted, and value should also be double quoted, except number (if you double quote a number, it becomes a string). Like this:
{
"name1": "stringValue",
"name2": aNumber
}
