React Series Part-0

Nisha Srivastava — Tue, 18 Jul 2023 10:03:11 +0000

Namaste, dear reader!

In this ReactJS series, I'll be covering the entire topics of ReactJS.

First things first! ReactJS is library of Javascript and not a framework.It was developed by Facebook in 2011.

It is widely and insanely used for creating fast and interactive user interfaces. ReactJS is way ahead of its potential competitors e.g. Angular JS and Vue js.

The entire ReactJS application made up of reusable and independent set of components.

Every react app has atleast one component which is referred as the App component.

App component represents the react app and all the components are placed inside it.

Since React is a library, it has a very specific purpose .i.e to create user interfaces also know as views.

React can also be used in the parts of our existing application and it will not disturb the existing technology of the application. This is one of the major differences between React and Angular.

Let's see who all are using react.

That's about it in the Part-0
Stay tuned for other series where I'll be discussing all things ReactJS.

You're beautiful, keep smiling : )

Okta's auth0

Nisha Srivastava — Wed, 26 Apr 2023 17:00:25 +0000

Set up authentication in the most efficient way with Okta's auth0

We often deal with this requirement where we're ready with the website be it coding it's features and functionalities but authentication is yet to be configured on the website

And authentication probably is the last feature to be configured yet the most important one.

I've come across one of the most efficient ways to configure this feature to your application.
With the help of auth0 of Okta, one need not to sit and write the code for all the logic required.

Okta's auth0

reduces the manual effort to a large extent.
No manual coding required.
No need to set up separate database.
Provides best authentication out there.

Documentation to configure auth0 to your application is available here

Feel free to comment below in case you get stuck, I'll be pleased to be of any assistance here.

Hope you find this helpful.

Cheers!

Hey there!

I'm looking for peers to code together/learn together, talking about myself I work as Solutions Engineer.

Comment down and let's begin.

Thanks in advance.

Serverless Technology

Nisha Srivastava — Mon, 16 Jan 2023 21:06:57 +0000

The very first thought crosses our minds while hearing Serverless is there won't be any Servers , isn't it?

Let me make it very clear,
Serverless does not mean that there are No servers.
Yes, the name Serverless is deceptive.

Before going in more depth about Serverless technology

Let's first understand,
What actually a Server is?

A computer which is designed to function 24/7 in order to provide services to computers or users(widely referred as client) on a network. e.g. Web Server, Email Server, Game Server

If you're someone who've hosted their website on any server, must be aware of the fact that

Servers need a lot of maintenance, provisioning and handling.

let's understand Serverless now

In Serverless technologies, everything still must run in servers only, it's just that users/developers do not have to manage/handle/provision the servers anymore.

Yes, this is what it is in simple terms.

It boils down to, the user experience is serverless but the same does not hold true in case of service providers.

More on Serverless

In Serverless, one does not have to worry about maintaining the servers and their underlying infrastructure such as replacing failed hardware, reliable internet and updated software.
It leads us to focus entirely on our application.

Let's discuss some major benefits os Serverless

We only have to pay for exact usage.
It gets easier to scale up and down.(No growing pain when your site or service sees a spike in traffic)
Don't have to manage Servers.

Will continue more on it in the upcoming blogs
What are your thoughts on Serverless technology?
Comment it down!

One more thing,
Keep smiling, you're beautiful :)

Containers and Virtual Machines.

Nisha Srivastava — Tue, 02 Nov 2021 19:27:15 +0000

Brief insight on containers and VMs

Operating Systems keep track of memory, RAM, Disk and devices, and if you run multiple programs simultaneously, all these resources of OS will be shared among the programs as per their requirements.

Now let's take an example where 1 of your programs is using port 80 and another program too needs to run on the same port, and if it tries to use the port, it will crash because port 80 is already in use.

It is one such example where containers and VMs come in use.

If you move your programs into containers or VMs each of them will have its own version of shared resources, files and network ports.

Containers provide the mobility, you can move and run your application easily.

Let's take a scenario where you are working on an application on your machine. Now that application will have certain configurations, binaries and other files and if you ship the same application and try to run it on another machine, it won't run if the machine does not fulfills the configuration requirements as per the application's demand of it. But if you have containerized it and then ship, no such issue will arise.

There are some similarities and so many differences between containers and VMs

Let's see that in the next post.

Enough of containers and stuff, let me make one revelation about you, You look best when you smile xD.

Arctic Code Vault

Nisha Srivastava — Tue, 28 Sep 2021 19:05:58 +0000

In one word, brilliant

When I read about it, I found this whole AWA thing out of this world

What is Arctic Code Vault?

It is a data repository. a mere data repo? Nope

The GitHub Arctic Code Vault is a data repo that is preserved for future generation.

On 02/02/2020 GitHub took a snapshot of every active public repository of GitHub and stored it in the Arctic Code Vault.

Those millions of repo were designed to last for 1000 years.

It is preserved in Arctic World Archive (AWA) which is located in decommissioned coal mine in the Svalbard archipelago, closer to the North Pole than the Arctic Circle.

The idea behind preserving these repo

It is much less likely that in case of global catastrophe, we could lose everything stored on digital media, in upcoming few generations.

In worst case, if it gets true our today's vital codes will be completely lost and most likely they'll be forgotten, so to prevent these things from happening, GitHub Arctic Code Vault is preserved for long years.

Hope it helped xD

Version Control

Nisha Srivastava — Sun, 26 Sep 2021 15:46:48 +0000

In the previous post I mentioned the stages of DevOps and the first being Version Control

Version Control

It is basically all things managing the source code.

Version control is of 2 types.

Centralized Version Control
Distributed Version Control

1. Centralized Version Control

In centralized version control there is one main repository and multiple users commit and update in that repository.

All changes in the file are tracked in the centralized repo/server

In case you lose your central repo, your whole source code will be gone and this is one of the major drawbacks of centralized version control system.

examples of centralized version control

Tortoise SVN
Perforce
CVS

2. Distributed Version Control

To overcome the drawbacks of centralized Version Control ,distributed version control was introduced.
In this type of version control, a developer clones the main repository of the project and saves it to his/her local hard disk
(disk space is not a matter of concern here as disk space is so cheap that storing many copies of a file doesn’t create a noticeable dent in a hard drive’s free space.)
After cloning the central repo, user commits and updates in the local repo and then do the push pull events to central repo.
If the data on central server is lost, there stays a sense of relief because of repo of project being present in the machine of developers.

There are plenty of advantages of using distributed version control system over centralized one.

Examples of distributed Version Control

Git
Mercurial
Bazaar

We'll talk about the pros and cons of using both in the next post.

What is DevOps?

Nisha Srivastava — Thu, 23 Sep 2021 15:51:22 +0000

Last year when I heard the term DevOps, I thought it would be any technology and trust me not only me but many of us think it as of a certain technology at first.

If not technology what is it then?
You must have come across various SDLC methodologies from waterfall to agile.
DevOps too is a methodology but it is not technically the SDLC methodology, but its goal is similar to that of the SDLC methodologies and that is to maximize the software project success.

DevOps is a software development strategy, which bridges the gap between the development part and the operations part.

It has agile inspired concepts.
It has various stages that altogether helps in maintaining a well tested and high quality product running.

The stages of DevOps are:-

Version Control
Continuous Integration
Continuous Delivery
continuous Deployment

Once the application is live that is deployed on the prod server, it is continuously monitored.

To execute these above mentioned stages various different tools are used and that we will discuss in the next post.
