The best way to keep the footer at the bottom of your web page
Tags: footer, css, flexbox, styling
Published: 2020-08-25 14:14:50

# Introduction
Have you ever came across the scenario where the page content is not enough to stick the footer at the bottom? Like so.
![Footer Not at the bottom](https://dev-to-uploads.s3.amazonaws.com/i/khae0e2gle201ghy09j5.PNG)
In this blog post, we will explore the best way to solve this problem.

# Code
The code for this blog post [can be found here](https://codepen.io/glorious73/pen/Vwappap).

# Method
The best solution for this problem is to use CSS Flexbox. Flexbox allows you to place your items in a row or a column, and it provides the option for one or more items to span the entire row/column. You can read a full guide at [CSS Tricks](https://css-tricks.com/snippets/css/a-guide-to-flexbox/).

# Implementing the solution
Basically, set the `display` property of the body to `flex` and set the `flex-direction` to `column`. Then, give it two children, a div with the class `container` (or anything you'd prefer) with the `flex-grow` property set to `1`, and the `footer`.

The magic here is to then set the `min-height` property of the body to `100vh` allowing the container to span the entire height of the screen's view port, and sticking the footer in the bottom in all cases.

What you need to know about Node.js
Tags: node, javascript, mongodb, express
Published: 2020-08-25 14:12:00

## What is Node.js?

- Node.JS is a concept for executing JavaScript on the server.

- Ryan Dahl, the original creator of Node.js, who has recently released another ground-breaking technology called Deno.

- Node.js is a cross-platform, open-source JavaScript run-time that is based on the V8 JavaScript engine found in Google Chrome.

- A non-blocking, single-threaded, event-driven I/O model

- NPM packages are used in the development of Node.js.

- It has shown to be the greatest tool for creating data-intensive, quickly scalable, and network applications.

## The underlying architecture of Node.js

Node.js's foundational components include JavaScript, V8, libuv, C++, and JavaScript. As Node developers, the five characteristics provide a greater degree of abstraction that greatly facilitates our work.


- V8 Engine

  - Without it, Node.js would not have been able to understand the JavaScript programs we create.

  - It is in charge of converting Node.js code into machine code that the computer can comprehend and properly execute.

- Libuv

  - Asynchronous I/O (Input/Output) is a key focus of this open-source software.- 

  - Node.js has access to operating systems, file systems, networking, and other systems thanks to this layer.

  - It implements the two Node.js functionalities that are most crucial:

  - **Event Loop**: this is in charge of carrying out basic operations like Callbacks, Network IO, and others.

  - **Thread Pool**: In charge of heavier tasks like file access, compression, and other things.

- The V8 and Libuv are both built in C++, and the V8 also includes some JavaScript code in its library. In other words, JavaScript and C++ were used to create the language node.js

## Apply Node.js to:

- Streaming of data

- API with database integration (preferably NoSQL Databases)

- A real-time chat program

- Server-side web applications

- Hardware programming 

## Avoid using Node.js for:

- Programs that use a lot of server-side processing (High CPU Intensive usage)

## Install Node.js now.

- Go to [Node.JS](https://nodejs.org/)

- Pick the version that is compatible with your OS. Because they are stable, LTS (Long Term Support) versions are strongly suggested.

- Download and set it up.

- Keep in mind to read and follow each stage's appropriate instruction.

## Checking to see whether Node.js is installed properly

- Open a terminal window or CLI (Command Line Interface) and enter the following command:

```shell
    node -v or node --version
```

A Peek At jQuery

Learning how to program can be a bit intimidating at first, but no worries I've found an amazing tool that can inspire you to dig deeper into programming. That tool is j Query! A JavaScript library or framework designed to make manipulating the DOM easier and solve browser compatibility problems. 

## Getting Started
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/yjho2pfg0m449j1isvyc.png)
Start up your code editor and in your html file put a script tag inside your head tag. In the script tag you will link your src to a local file or a CDN (Content Delivery Network). For further instructions check the j Query download page https://jquery.com/download/

## Selecting Elements

![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/rfzgv2sdfzs73q140f6f.png)
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/qz235bq2afa3w8lbjziv.png)

You can select any element in the DOM using $("value"). In this example i'm doing something very simple by just changing the header but only for you to understand the syntax. I follow up with .text("") method to change the text to "King of the Jungle"! You can select by specifying the $("element") , $(".className") , or $("#idName").

##Styling 
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/s85ujxylqtwo107w2a2r.png)
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/n2kpfa7vwtepg3jrop7v.png)
The way you style with j Query is by using the .css() method.The first argument will be the name of the property and the second a value. This can be very effective in manipulating multiple things at once or even just one element at a time without the use of writing loops in JavaScript.
##Events
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/ehkbxazxx7foceizmrk5.png)
![Alt Text](https://dev-to-uploads.s3.amazonaws.com/i/inq7n5078mfjytfd3mvc.png)
The .on() method is a popular method that will carry out code based on the specified event. Since we want a li to change color if it gets clicked. We must use the keyword **this**, which refers to the specific li that was clicked. If we were to use Vanilla JavaScript (JavaScript without j Query) there would be more code to carry out this event. This is more understandable, concise, and easy to write.

##Conclusion
It is a great debate if new comers should learn j Query. Developers say it's easy to write spaghetti code because of it's simplicity. It was made to solve browser compatibility problems in 2006 but we don't have those problems anymore. Although, Uber, Twitter , Reddit and many more companies still use j Query.I suggest to learn j Query especially if you want to be on the front end.Then when you get a better understanding of things learn some JavaScript to have more control of your code.Even take a look into j Query's cousins React and Angular. There are many resources and YouTube videos that can help you. Why not learn something new? Happy Coding. Thanks for reading!

👋🏾 Hey Folks!

When I first started using Hooks in React, I always thought it would have been helpful to have a directory that displays all the different ways Hooks from the core React library can be used.

So in the last few weekends I went ahead and built a simple app to attempt the above called [snippetsofhooks.dev](https://www.snippetsofhooks.dev/).

<a href="https://www.snippetsofhooks.dev" target="_blank">
<img src="https://www.snippetsofhooks.dev/social-image.png" />
</a>

The app provides code examples for the different variations of each official React Hook with helpful prompts and downloadable PDF cheat sheets.

I really hope this is helpful for anyone who is new to Hooks and/or just need a good reference point to come back to at times! This is still a WIP and I'm thinking of adding a few things later but do let me know if there's anything you think is worth improving. Feel free to leave a comment and I'm always available on Twitter as well - [@djirdehh](https://twitter.com/djirdehh)!

MongoDB interview Q/A

### Q1: Explain what is MongoDB? ☆

 

**Answer:**

MongoDB is an open-source document database that provides high performance, high availability, and 

automatic scaling.

It's Key Features are:

* Document Oriented and NoSQL database.

* Supports Aggregation

* Uses BSON format

* Sharding (Helps in Horizontal Scalability)

* Supports Ad Hoc Queries

* Schema Less

* Capped Collection

* Indexing (Any field in MongoDB can be indexed)

* MongoDB Replica Set (Provides high availability)

* Supports Multiple Storage Engines

 

 

### Q2: What is “Namespace” in MongoDB? ☆☆

 

**Answer:**

MongoDB stores BSON (Binary Interchange and Structure Object Notation) objects in the collection. The concatenation of the collection name and database name is 

called a namespace

 

 

### Q3: What do you understand by NoSQL databases? Explain. ☆☆☆

 

**Answer:**

At the present time, the internet is loaded with big data, big users, big 

complexity etc. and also becoming more complex day by day. NoSQL is answer of 

all these problems; It is not a traditional database management system, not 

even a relational database management system (RDBMS). NoSQL stands for “Not 

Only SQL”. NoSQL is a type of database that can handle and sort all type of 

unstructured, messy and complicated data. It is just a new way to think about 

the database.

 

 

### Q4: What is the difference between MongoDB and MySQL? ☆☆☆

 

**Answer:**

Although MongoDB and MySQL both are free and open source databases, there is a 

lot of difference between them in the term of data representation, relationship, transaction, querying data, schema design and definition, performance speed, 

normalization and many more. To compare MySQL with MongoDB is like a comparison 

between Relational and Non-relational databases.

 

 

### Q5: What is the difference b/w MongoDB and CouchDB? ☆☆☆

 

**Answer:**

MongoDB and CouchDB both are the great example of open source NoSQL database. 

Both are document oriented databases. Although both stores data but there is a 

lot of difference between them in terms of implementation of their data models, 

interfaces, object storage and replication methods etc.

(POSSIBILITIES) what languages are good to learn? 
Tags: python, javascript, kotlin, java
Published: 2020-08-25 13:38:04

Right now, I’m focusing on Python + Django. 
I like it, it seems better than JavaScript at times, but it seems like it’s a little bit “categorized” in a way that it’s, limited to what you do. 
JavaScript can do allot, and that’s were it’s get annoying with how much code you have to think of in a way.
I like the “concept” of how swift looks like, it seems like objects are right there to style and define? 
Java or Kotlin.... kinda seem that way. Are they good? 

I like python better than JavaScript, but I’m kinda liking React better than Python. 

React adds a “structure” to JavaScript. I don’t like plain JS in a .js page. 

I’m leaning towards using Vue again after better knowing JS with React. But,
Idk what to really focus on with the “stable” type of needs with code.
Is Kotlin good, or Java? Is Python really on a rise to what people want? 

Again..... if you can see what I mean by.... how swift looks like how it works, where you can style/define at the same time your “programming”? I like that, but I like a better “narrowed down” plate of code.

Hi All beautiful people,

I want to create a home automation system for my home. I could buy a pre-built service but I always wanted to learn about IoT and this is a use case I can work on. 

I don't have knowledge of Hardware, so need you guys to help me select hardware through which I can control lights and fans to start with. 

I have read many places about Arduino and Raspberry Pi. People are building some really cool stuff with these. 

For coding, I will use NodeJS to create connection and API's

Published: 2020-08-25 13:02:14

Modifiers to the file modes you can use in Python Programming Language? 



▪ The most important one to know for now is the + modifier, so you can do 'w+', 'r+', and 'a+'.



▪ This will open the file in both read and write mode and, depending on the character used, position the file in different ways.
How do you test number of renders in React?
Tags: react, reactnative, testing, javascript
Published: 2020-08-25 12:54:30

## TL;DR

Introducing [react-performance-testing](https://github.com/keiya01/react-performance-testing) that is new React test library to measure performance(number of renders, render time).

## Why?

If you are developing high-performance features, you would like to write test about the number of renders or render time. However we have to check with devtools or Lighthouse manually, and we could not test these cases automatically. Additionally, we cannot predict re-renders without getting nervous. The react-performance-testing provides a solution for these cases.

## Solution

The react-performance-testing provides a simple and easy way as a solution for the above problem. It provides some features by monkey patched React. We can count the number of renders and measure renders time as well, and we can test by using these values.

## How to use?

You can use `perf` and `wait` method.
 
`perf` method is used to measure rendering performance. This lib measure rendering performance by wrapping your component with own component internally. But this component is very small, so this component do not affect to your component. 

`wait` method is used wait for rendering process is completed. This is because, this lib measure performance after rendering process is completed.

You can use as bellow.

```jsx
import React from 'react';
import { render, fireEvent, screen } from '@testing-library/react';
import { perf, wait } from 'react-performance-testing';

test('should render two times when count button is clicked', async () => {
  const Button = ({ name, onClick }) => (
    <button type="button" onClick={onClick}>{name}</button>
  );
  const Counter = () => {
    const [count, setCount] = React.useState(0);
    return (
      <div>
        <span>{count}</span>
        <Button name="count" onClick={() => setCount(c => c + 1)}/>
      </div>
    );
  };

  // This lib monkey patches React in perf method.
  // So, you need to pass React module.
  const { renderCount } = perf(React);

  fireEvent.click(screen.getByRole('button', { name: /count/i }));

  // renderCount.current have each component name object,
  // and it have number of renders in its `value` property.
  await wait(() => {
    expect(renderCount.current.Counter.value).toBe(2);
    expect(renderCount.current.Button.value).toBe(2);
  });
});
```

Note that you should use `wait` method. This is because, `renderCount` is assigned value after React's render process is completed.

## Thanks

Thank you very much for reading.

If you want to test about number of renders, please try it!
I hope this lib will be helpful for you.

What does 'w', 'r', and 'a' mean in Python Files Topic ?
Tags: python, tutorial, help, ddsry
Published: 2020-08-25 12:40:24

Meaning of 'w', 'r', and 'a' in Python Programming Language Files Topic ?


▪ It's really just a string with a character in it for the kind of mode for the file.


▪ If you use 'w', then you are saying "open this file in 'write mode" - hence
the 'w' character.


▪ There's also 'r' for "read," 'a' for append, and modifiers on these.

This July I committed to learning web-development from scratch. I am employed full time so I decided to learn in teeny-tiny chunks whenever I get time. 

I tried to be consistent and just stuck to learning on weekdays and tried disconnecting on weekends. I made a point to take notes and upload all written code to Github for tracking. 

Looking back it feels nice to see the knowledge map expand and the compounding effect in action. But most importantly it was the most fun I had in quite a while.
