Imported and Inline CSS in React

I'll show ith an example how inline CSS works in React

App.js

import React, { Component } from 'react';
import './App.css';


class App extends Component {

  render() {

    const style = {
      backgroundColor: 'white',
      font: 'inherit',
      border: '1px solid blue',
      padding: '8px',
      cursor: 'pointer',
      borderRadius: '6px'
    };

    return (
      <div className="App">
        <button style={style}>SWITCH</button>
      </div>
    );
  }
}

export default App;

App.css

.App {
  text-align: center;
}
Above example shows both, CSS from CSS file and inline CSS in React

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.

Resolve: Uncaught TypeError: firebase.database is not a function

If you are getting the error: Uncaught TypeError: firebase.database is not a function Resolve it by including firebase-database.js in your html page as follows: <!-- The core Firebase JS SDK is always required and must be listed first --> <script defer src = "https://www.gstatic.com/firebasejs/6.2.4/firebase-app.js" ></script> <script defer src = "https://www.gstatic.com/firebasejs/3.1.0/firebase-database.js" ></script> That is it. Let me know if this was helpful.
