--------------------------------------------------

It is happning even you are providing the trust level as full like below.

<system.Web>
...
    <trust level="Full"/>
...
</system.Web>

-----------------------------------------------

And fix for that is
You need to contact the  big rocks supporting team as your site need the  configuration of 4.7 , as it is build in MVC 5.0 + version so just check with them and they will give CAS access to full. Even if you do setting in PLSK it wont work they will provide it to you.

Error : Set the value to `true` or `false` explicitly to silence this message. node_modules\mssql\lib\tedious\connection-pool.js:61:23

Issue :

While creating the NestJS with MSSQl application after creating the ormconfig and take the reference .

Getting the warning message as :

[Nest] 12236   - 05/23/2020, 6:27:56 PM   [NestFactory] Starting Nest application...
tedious deprecated The default value for `config.options.enableArithAbort` will change from `false` to `true` in the next major version of `tedious`.

Solution

In your connection options you should add:

extra: {
  options: {
     enableArithAbort: true // or `false`. Just set it explicitly to silence the warning message
  }
}

Default and Named exports in ReactJs

There are two ways you can import your classes it based on how you will do the exports.

import React from 'react'  // Default Export

import {Component} from 'react' // Named Export

Here you can see the import is with bracket and another one is without bracket.

As I told in the first line export are two type:

1. Default Export

2. Named Export

Any of the components can have one default export and can have 0 or more than 1 named export.

Example of Named export as like.

export const Greet = () => <h1> Hello Satya</h1>

Than it will be import to the another component as like

import {Greet} from './myComponentes/Greets' // named export

import {Greet as SomeName} from './myComponentes/Greets';

If you will see the above Greet is in side of curly bracket.

Example of default export

Exporting a function values like below.

function Greet()

{

    return <h1> Hello Satya</h1>

}

//export const Greet = () => <h1> Hello Satya</h1>

export default Greet;

Now you can import it to the other component as like

import Greet from './myComponentes/Greets'
