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
port: "8001"
^
SyntaxError: Unexpected token p

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
}

I have installed Node JS version 12, cloned node-oracle db from github.
I have also set OCI_LIB_DIR Path as mentioned in this article.
module.exports = {
user : process.env.NODE_ORACLEDB_USER || "hr",
// Get the password from the environment variable
// NODE_ORACLEDB_PASSWORD. The password could also be a hard coded
// string (not recommended), or it could be prompted for.
// Alternatively use External Authentication so that no password is
// needed.
password : process.env.NODE_ORACLEDB_PASSWORD || abcd,
// For information on connection strings see:
// https://oracle.github.io/node-oracledb/doc/api.html#connectionstrings
connectString : process.env.NODE_ORACLEDB_CONNECTIONSTRING || "jdbc:oracle:thin:#localhost:1521/orcl",
// Setting externalAuth is optional. It defaults to false. See:
// https://oracle.github.io/node-oracledb/doc/api.html#extauth
externalAuth : process.env.NODE_ORACLEDB_EXTERNALAUTH ? true : false
};
I have created a basic connection in SQL developer, would it help.

set the credential environment variables to your DB credential values before you start Node.js. The error message says NODE_ORACLEDB_USER is not set.
Alternatively you can set the values directly in your getConnection() calls:
connection = await oracledb.getConnection({ user: 'hr', password: 'welcome', connectString: 'localhost/orcl' });
But be careful of hard coding passwords.
Use a valid connection string; a JDBC connection string is not usable (Node.js is not JDBC). See the node-oracledb doc JDBC and Oracle SQL Developer Connection Strings for how to determine what to use. Based on what you posted, you should use just localhost:1521/orcl.
Save yourself some time, and read the node-oracledb installation manual, the documentation, and the examples.

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.

I'm trying to create a connection between nodejs and redisql i fall into problem when creating table something called TypeError: Wrong input type "String" for args
the stacktrace will be added at the end of post, i have added
const redisql = require('redisql');
const sqlClient = redisql.createClient();
sqlClient.create_table("employee", " id int , name TEXT , salary double ", redisql.print);
once i run the third command i get this stack trace
