Hello everyone, my name is Raji Oluwatobiloba, I am a software developer. I love to write and I am planning on using this platform to teach/communicate to people from my own little experience!

 

Hello how are you ? My name is Robinson and I write to you from Venezuela. I just started to learn Reactjs ... and I would like if you could guide me on the beginning of the session. I already have the Login interface and I redirect to the dashboard (in this case) ... but I don't know how to handle the user session? also the expiration time of that session? I've seen examples with LocalStorage but I don't know if that's a good practice ... I'd like to know if you can help me with an example? I did my backend with NodeJs Express connected to a Sql Server database ... Greetings...my email : loretoruiz@hotmail.com

 

Hi nice to meet you. You might be able to get some experience in the following project github.com/hyperledger/blockchain-... where I've joined as a OSS contributor. The project is using these tech stacks and always welcoming a new contributor. Cheers!

 

Hi Robinson, happy to help. Can we chat on hangouts or whatsapp?

Hello, thanks for answering ... I do not speak English ... I speak Spanish ... but can you help me with the google translator ... can you show me an example of what I ask in the forum?

Okay, if i were in your shoes, i'd use localstorage or cookies.
but I prefer localstorage.
normally you will be getting a token from the backend when you are logging users right? so just do it this way:

this will be at the point of logging in users
axios.post ('url', {
user,
})
.then (response => {
localStorage.setItem ('token', 'randomstringtokentopersistdata');

then on your dashboard page, just go like this.

const token = localStorage.getItem ('token');

you can store this token in a state and use it all over your app as it can be accessed anywhere.

I understand friend ... and how do you manage the session expiration time?

You can use JavaScript session storage

sessionStorage.setItem('token', 'randomstring')

const data = sessionStorage.getItem('token');

// to remove user data from sessionStorage

sessionStorage.removeItem('token');

I understand friend ... I have a doubt ... how are global variables handled in Reactjs ?? that is ... if I want to save and be able to use the variable == >> const name = '' in ALL my application; that variable will take a value when the user enters the system ... and from another component I want to use it ... that is, I want to get the value of that variable name ... can you help me?

You can store that variable in state and pass it as props to whatever component you need it(you'll need to read more on passing props) React official documentation is the best place to start.

Moreover, you'll reach a stage where passing this supposed variable from one component to another will be a pain in the ass, then you should use a state management, the popular one is redux. You'll need to go learn redux too. But for now, since you're just starting to learn react, try learning how to pass state as a props from one component to another.

Let me know if you need more clarification.

 
 

Hello, nice to meet you! Awesome to see your already helping others out!

 

Welcome Raji.. That's the great goal to teach people.. best of luck here

 

Hi Raji! Same here, I think teaching is a fundamental way to solidify our own learning.

 

Hello everyone!I am Ishini Avindya. I am a writer, graphic designer, game developer, and a content manager. I write mostly on Hyvor Talk Blog about blogging, commenting,etc. As a graphic designer, I have designed lots of graphics mainly for Hyvor and several companies. Game developement is one of the most favortie things I love to do. I often use Csharp. I often do writing here to help bloggers, developers, and for the beginners. I want to help them and share my ideas with them.

 

Yeah Sharing is Caring.. Welcome Ishini to dev.to awesome community.. I am also new and trying to get better in software development..

 

Good luck with your plans. If you needvto know anything about blogging, or to solve problems of blogging just refer my articles.

 
 
 
 

Welcome, Ishini! I find the graphic design a really creative work. Good luck with that!

 
 
 

Hello World, I am Juan an inspiring self taught web developer with a true love and passion for code. Really looking to learn and improve my skills here and hopefully be able to help beginners like myself.

hey Juan, take a look at our website Mangoitsolutions, here you will find most of the relevant topics related to web development

 

What kinds of applications do you like writing?

 

Hello, well my current skills allow me to build static sites, but would really want to be able to add a lot more functionality to the sites. Currently learning node.js, mangoo and cant wait to start react. Goal is to land a job as a front end developer and ofcourse keep learning and improving.

Hi, Where are you based ?

Im lead dev at MEV Suite (mevapp.com) and we are looking forward to hiring Frontend Interns from anywhere in the world who may join our team fully.

See you around here.

Thats nice, Have you hosted any work so far already ?

 

Hi Folks! I'm a software dev (mostly Ruby) and a random hobbyist. I've been stumbling across dev.to posts for a while, finally decided to take the plunge. Happy to be here ^_^
-Viki, she/her

 
 

welcome Viki.. whenever I see ruby developer.. I feel happy.. Ruby is underrated and people often bash ruby :(.. but I really enjoy learning ruby.. currently trying to get better in ruby and rails..

 

Thanks! ^_^ I really enjoy Ruby, and it's perfectly fine for a lot of things. It does have some limitations I don't fully understand, especially around concurrency and performance, and that's okay. Not everything has to be as fast as it can possibly be, and Ruby can also be made performant enough for a lot of use cases.

I heard ruby 3 will introduce static type checking and much more to make ruby fast.. let's see

 
 
 
 

Hey, Call me wiz lol..... Amma keep it short... Really hope this platform can help advance my development skills

 
 
 
 

Hello, this is Daniel Roy Greenfeld from Los Angeles, California, USA. I am python, javascript, and C#/Unity developer who has worked for NASA, EventBrite, and an InsureTech. I've written books on software, Two Scoops of Django and Django Crash Course. I'm working on more books for Python and C#/Unity.

I love being a constant learner and student. I eagerly devour what people have to say on coding. The day you stop being willing to learn is the day your career as a developer is over. :-)

 

I agree with you 100%. The desire to learn is integral to success as a developer. I've been a developer for over 20 years, across many different languages and technologies. Whenever I'm asked about this type of career, I point out that you will never really feel like you have arrived at a full understanding of anything - there is ALWAYS something new to learn and so many different areas of expertise. This is part of what I love about it! Never bored. ;-)

 
 

Hi Daniel,

Nice to meet you here. Your book helped me to develop better system with Django at our place. Thank you very much.

 

Hi Devs! 👋 I'm Víctor and I'm a Full Stack developer. I love code, the Cloud, DevOps and also interested in cutting-edge technologies that can help solve real-world problems, such as Artificial Intelligence or Big Data...I hope to contribute to this fantastic community!

Woow nice to reading! i am starting as a trainee in a big company in my country, it is supposed i will get full-stack and I will do my best to get it!

 

Debugging and troubleshooting got me here, but the dev articles made me stay .. Unlike Medium (sorry) I find dev.to to be more tech focussed, meaning less of promotion and more code..

PS: I am an active 9gager too.. so here's a 🥔 (potato) for long post.

 

Hello, I'm Jared!

I'm (professionally) a web developer, but (unprofessionally) I try to tackle graphic design & illustration, game design & development, 3D modeling & animation. I also enjoy reading, wood carving, archery, the earth, my girlfriend and my 2 cats :)

I followed Dev.to on Twitter for quite some time, but never found my way to the site!

Well, I'm here now and excited to see what I can learn. 👋🏼

Hi Guys!

Im David from Spain, actually working like Junior Web Development and studing CS Degree, also like make little projects with arduino.

Im here because love the community and want to learn a lot of new things and improve my code and Why Not? make some new friends.

Thx for read!😊

 

Hello all, I'm Charlie. I'm a technical consultant, which can and does take many directions, not limited to: redoing a facility's wifi setup because it was terrible, auditing infrastructure, making sure in-development IoT devices actually behave themselves and write code only if necessary. But since this is DEV, outside of the business context I port software to run on FreeBSD, my operating system of choice, and play with single-board computers and microcontrollers. Oh, and I'm a ham radio operator, but focusing on the digital/computer side of things.

Here to force myself to get better at documenting stuff informally (read: blog, share the posts here) as well as help others learn things (rather than scream into the void).

 

Hello world!
I'm Maxime. I'm a (young) software engineer (apprenticeship, studying computer science at the same time) at Airbus France. I build Data Driven Applications to help quality guys, production line & currently flight line.

So yeah, I mainly work with Python (Pyspark/Pandas) but I also do a lot of web development at work & on my own. I also was a web developer in a young startup before. For the web, I mainly work with PHP (Laravel), NodeJS & recently Django (falling in love), and for the front side I'm a VueJS lover for a long time! I've tried React but it's not my cup of tea.

I read a lot on dev.to and I'm considering writing on it, maybe soon (gosh that's so scarry).

See you guys!
PS: I love coffee.

 

Don't be scared. Any knowledge will be greatly received by someone. Not everyone can learn everything about coding. Be brave, start posting. There are a lot of novices on here, like myself, so go for it!!

 

Greetings,

My name is David and I am passionate about anything Azure, DevOps, and Automation. I enjoy speaking at conferences and other events. I am not that good at blogging or writing posts on social media.
I am a lifelong learner, so I certainly hope that dev.to is a great place to learn and share knowledge :)

 

A software developer with 7 years of experience in Programming. I have been working on Microsoft Technologies along with JavaScript and Python

 

Welcome Gyanendra.. :) hope to learn some software development tricks and tips from you..

 

Thanks Faizan. Yes , i will do my best to contribute from my experience. And will learn from others as well.

 

Hey everyone, Jaryl here, have been doing webdev for some time, mostly, ruby and javascript. Have been thinking to move from Medium to dev.to, what's the community stand on reposts from other platforms?

 

Hello DEVs,

I am Dharmen. I love working on the frontend. My favorite stack is Angular and Bootstrap with SASS. I also like to work on React. I have recently started writing blogs and contributing to open-source. I also have made a couple of libraries/tools on npm. In my free time, I like to cook and listen to Hindi pop music.

 

Hello world!!!!! I am Sam, an aspiring full stack web developer currently studying at General Assembly's Software Engineering Immersive course. Based in Singapore. Would like to learn from all developers about the fun of coding and computer science :)

 

I have a pyspark project where I have a dataframe shown below:

   +----------+--------------------------------+
   | Index    |           flagArray            |
   +----------+--------------------------------+
   |    1     | ['A','S','A','E','Z','S','S']  | 
   +----------+--------------------------------+
   |    2     | ['A','Z','Z','E','Z','S','S']  |
   +--------- +--------------------------------+

I want to represent array elements with its corresponding numeric values.

     A - 0
     F - 1
     S - 2
     E - 3
     Z - 4

So my output dataframe should look like

   +----------+--------------------------------+--------------------------------+
   | Index    |           flagArray            |           finalArray           |
   +----------+--------------------------------+--------------------------------+
   |    1     | ['A','S','A','E','Z','S','S']  | [0, 2, 0, 3, 4, 2, 2]          | 
   +----------+--------------------------------+--------------------------------+
   |    2     | ['A','Z','Z','E','Z','S','S']  | [0, 4, 4, 3, 4, 2, 2]          |
   +--------- +--------------------------------+--------------------------------+

I have written an udf in pyspark where I am achieving it by writing some if else statements. Is there any better way to handle the same.

 

This week is my first week as a Developer Advocate for JFrog. I'm excited to learn from all of you and hopefully leverage my years of development experience to contribute some meaningful content. Can't wait to jump in! At the moment I'm looking into the history of containers and deep diving into how we use them today.

 

Hello, all!

My name is Matheus, I am from Brazil but live in Germany since mid-2018. After attending to :clojureD conf this weekend I am more motivated to start writing about my experiences as a software engineer.

I've been using Java for most of my career but I have a "crush" on Clojure and functional programming languages in general.

 

Hello all,

I'm a software developer with about, ah, 30 years professional experience. Lots of C++, Objective-C, Python, Java. Increasing amounts of Swift. I've done a lot of media programming and I'm currently working with an avatar start-up in Venice, California. I've been living in Los Angeles for about five years, and previously spent many years in the UK and Australia.

I'm joining because a Microsoft employee published an article on Twine here, which I though was pretty damn cool, considering that I'm an Interactive Fiction aficionado.

 

Hello-world ...
this is John from South Dakota coming to this community for sharing my experiences and learning from you all. I am currently in the Medical field and would love to solve some problems I see in that space. I hope I can get some inspiration from this community as well as give some as well!

 

I lead about 100 people in science and engineering. Other than bash, my github is no longer green. I learned golang and I am curious about rust. I love unikernels and low-level performance optimization. I am hiring, mostly PhD machine learning folks at the moment. I also have a Seattle director of paid internet marketing science opening.

 

Hey good people,
I'm Dylan! I live in Brooklyn and am currently self-employed. My background is in web dev, and I'm looking to really grow and sharpen my dev skills. I'm eager to learn new things and very eager to participate in this community. Looking forward to connecting with everyone!

 

Hey guys! My name is Sree and I'm a 20 year old striving to reach greatness every day of my life.

Really excited to be a part of this wonderful community. I consider myself a complete beginner(a fool, rather) when it comes to Tech (although, I might be a bit too modest in saying that). My main aim here is to learn as much as I can from you fabulous people and contribute to the best of my capacity for making something worthwhile.

 

Good luck and lots of Gods Blessing ! It's only the second month forthcoming to the next Flashy to happen Lately...Peace from within your heart = shiney atmosphere & serenity in balanced with harmonique environment !

 

Hi folks!

Decided to check out the community after receiving my Hacktoberfest t-shirt and stickers and wondering what the DEV sticker I got was all about.

Currently mainly a Python developer, but a generalist polyglot built up over the near two decades as a developer. Mostly game development between EA and Demonware (Activision), but the last handful of years outside the games industry at Salesforce. Open source advocate and contributor when time permits.

What are you (still) not interested in learning?

I'm interested in hearing not only what you are *not* interested in learning. But if you answered the question last time, has anything changed?
