MERN vs MEAN : WHICH STACK TO USE IN 2021

Bothe MEAN and MERN are full stack frameworks with Java coded components. The difference is that MEAN uses Angular JS while MERN uses the React JS developed by Facebook. Both aids developers to make reactive and intuitive UI. To understand which stack is the better one, we need to understand the underlying differences between them.

DIFFERENCES BETWEEN MEAN AND MERN

MEAN: Components include Mongo DB, Angular JS, Express, and Node. MERN: Components include Mongo DB, React JS, Express, and Node.

MEAN: JavaScript development stack. MERN: Open source JavaScript library.

MEAN: Uses Typescript language. MERN: Uses JavaScript and JSX.

MEAN: Copnent based architecture. MERN: None.

MEAN: Regular DOM. MERN: Virtual DOM.

MEAN: Steep learning curve. MERN: Better documentation.

MEAN: Bidirectional data flow. MERN: Unidirectional dataflow.

Both tech has high class features and immense functionality. The slight upper hand that MERN enjoys is in the learning curve. MERN is easier to grasp because the learning curve differs between Angular JS and React JS. Let us take a deeper dive into the benefits of MEAN and MERN stacks to understand the power of each of these stacks fully.

BENEFITS OF MEAN AND MERN

MEAN STACK

All types of applications can be developed easily.

Various plug ins and widgets have compatibility with this stack. For development that has a stricter time frame, this comes in handy.

The functionality skyrockets due to the availability of plug ins.

Developers enjoy community support since the framework is open source.

Real time testing is possible with the built-in tools.

A single language is used for back end and front end. This increases coordination and gets applications to respond faster.

MERN STACK

Front end and back end are covered by a single coding script.

The entire process can be completed using only JAVA and JSON.

Seamless development through the MVC architecture.

Real time testing through built-in tools.

Runs on an open source community and the source code can be easily modified.

According to Hacker Rank development skill report, 30% of developers went with Angular JS while 26% stayed with React JS. The report also mentions that 30% of the programmers wanted to learn React JS and 35.9% of developers prefer to develop using React JS, thus MERN stands slightly above MEAN when it comes to popularity.

As far as we know, in terms of ease of understanding and popularity, MERN is at the forefront now. Let us take a detailed comparison to understand who will win the race in 2021.

MEAN vs MERN : A DETAILED COMPARISON

Scalability, Security: Both MEAN and MERN are equally secure. However, in terms of scalability, MERN is at the forefront.

MVC: For enterprise level apps, a complete architecture needs to be maintained. MEAN is the better option for this.

UI: For an advanced and simple UI, MERN is the go-to stack. MERN facilitates user interaction.

CRUD: For CRUD (create, read, update, delete), MERN is the ideal stack. The React JS handles data changes quickly and has a good user interface as well.

Support: The Angular JS in MEAN supports HTTP calls and unites the back-end. Enterprise level app development will require third party.

libraries. On the other hand, React JS improves functionality through its supplementary libraries. MEAN scores slightly above in this section.

MEAN enhances the experience through the use of third party extensions while MERN would require additional configurations to do this.

In aspects of the learning curve, UI, scalability, and CRUD, MERN stack scores more than MEAN stack. However, in the aspects of community support and MVC MEAN stays ahead. In terms of security both are at par. However, the application of the stacks depend entirely on the business needs.

MEAN is more affordable, and is the first choice for startups and SMEs. Switching between clients and servers is easier. For real time web apps, MEAN is definitely the best choice. In MERN, the Virtual DOM enhances user experience and gets the developer’s work done faster. A stable code is maintained by React JS due to a unidirectional data flow. For coding for Android and IOS using JavaScript, MERN is definitely the way to go.

TAKE AWAY

Companies like Accenture, Raindrop, Vungle, Fiverr, UNIQLQ, and Sisense among others use MEAN in their tech stacks. Brands such as UberEats, Instagram, and Walmart use MERN stack. Both the stacks provide an incredible user experience. Stability and scalability can be achieved with both stacks.

From this we can conclude that enterprise level projects require MEAN over MERN. MERN makes rendering UI simpler. Both are reliable for a quick front end development.

MEAN is good for large scale application. MERN is good for faster development of smaller applications.

At Orion we have an excellent team that can help you with all your MEAN and MERN stack development needs.

Character Questionnaire: Merrinyn Delorsath

BASICS -

1. Height?

5′5″. (She is of average height. At least in her former settlement.)

2. Eye colour?

Black. (It’s actually dark blue.)

3. Do they need glasses?

No. (That doesn’t stop her from wearing one whenever she feels like it.)

4. Scars and birthmark?

None. (It’s hard to get scars when you’re always far from the action, drowning in books. She did get a paper cut a few days after leaving her old settlement, settling for the surface to learn more about this part of the world, though that amounted to nothing more than a few minutes of annoyance.)

5. Tattoos and piercings?

None.

6. Right or left handed?

Right-handed. (For a time in her youth, she instead she was ambidextrous. That was until she figured out the word she was looking for was “amphibious”.)

7. Any disabilities? Physical or mental.

None. (She can’t pronounce the letter “R” if it’s in the last syllable of a word, as in “wafer” or “paper”, ending up either mispronouncing it as the letter “W” instead, as in “wafew” or “papew”, or accidentally speaking in a British accent. Don’t tell her I told you this. She’s very sensitive about her rhotacism.)

8. Do they have any allergies?

None. (...though she once almost died after eating crab. That was most likely due to improper cleaning of the food. It never happened again. Strange.)

9. Favourite colour?

Seafoam Green. Or blue. (She also likes pink.)

10. Typical outfits?

Whichever works, really. I prefer clothing that would not impede my mobility over clothing that’s all for show. (She used to wear simple sleeveless, collarless, pants-less garments made of coral, see below, until she moved to the surface-world where a kind old lady gave her common clothes for free because she looked “cold” and “very naked”. Still, she tends to rip out the sleeves and collars and even pant-legs of her clothes whenever she feels like it, usually when she’s near the water and there’s no tedious socializing to be had.)

11. Do they wear any makeup?

No. (She does, but only rarely and mostly during “special” occasions.)

12. What weapon do they use, if any?

Between my magic and my staff, I can be quite the formidable fighter. (She isn’t. She has also been thinking of acquiring a trident recently. Three pointed tips are better than one blunt head.)

PERSONALITY -

13. Are they more optimistic or pessimistic?

Neither. I dwell in between optimism and pessimism. Nothing is ever absolutely positive or negative. There is also the middle, and there I thrive. (Technically, she’s more optimistic, considering she’s always optimistic that each day holds new things for her to learn. She does get pretty pessimistic when things don’t go her way, though, especially if she becomes obsessed with learning about something and her progress somehow gets impeded.)

14. Are they introverted or extroverted?

Neither. I am an ambivert. (Mostly true, though she leans more towards being an introvert, as she spends more time being an introvert, with all her research and reading; however, she doesn’t get drained as much when she has to be an extrovert, though she tends to avoid opportunities where she has to be one.)

15. What are their pet peeves?

When someone interrupts my research on anatomy by slaying the creature I am to observe. *very audible sigh* Brutes... (She also can’t stand people who can’t wait in line, even though she herself hates lines.)

16. What bad habits do they have?

Someone once said I’m terrible with making friends, though to be fair, I’m here to study and learn, not to make friends. (She spends way too much time with her books and research and not enough time connecting with real people. It’s uncertain whether this is because she’s such an obsessive sage or it’s just a triton thing.)

17. Do they have any phobias?

I fear nothing. Fear only exists when one does not understand something. I seek to understand everything. I do not fear. (Insects, especially flying insects, specifically cockroaches. She thinks they’re gross and they always have the high ground when it comes to the element of surprise. She’d probably like them if they were larger, though, since she’d at least be able to keep them from entering her orifices without permission. Oh, and falling from great heights. She hates that.)

18. How do they display affection?

I don’t. Affection is unnecessary. As long as you are useful and efficient, you are. (She really doesn’t. At least, she doesn’t know how to. Even her compliments are awkward and strange.)

19. How competitive are they?

Competition is good as motivation for personal growth, but only when it motivates a competitor towards personal growth. (She isn’t as competitive as others are, though it’s mostly because she’s a triton and tritons don’t really consider surface dwellers as competition. At least, that’s what she believes.)

20. If they could change one thing about themselves, what would it be?

No response. (It differs on a daily basis, more like it adds up, but she doesn’t take to it like changing herself because she doesn’t like herself. It’s actually more of changing something here and then something there to unleash the full potential of her existence. Like having eyes that see better in the deepest dark or gills that can allow her to safely breathe in any environment. It’s alteration in the spirit of evolution, not alteration because of emotions.)

21. Do they have any obscure hobbies or routines?

Is collecting forks an obscure hobby? (It is.)

BACKSTORY -

22. What are the names and ages of their close family members? Parents, siblings, etc.

My father’s name is Mernes and my mother’s name is Erryn. I have one older brother, Jharvas, and no other siblings.

23. Is their family alive and are they still in contact with them?

Yes, they are all alive and well. My father and my mother live together back home while my brother has also set out to, according to him, find himself. I’m certain he’s simply pursuing the vampire woman again. Men have never been quite as smart as us. (Her brother is indeed with a female vampire but he’s not pursuing her. They’re working together, trying to make a life with each other.)

24. Where are they from? City, nation?

I’m from the sea, the depths of which no surface dweller may survive. (Her settlement is within the oceans east of Hegaehend, far east. They call it the City of Sh'lafijn, though others simply refer to as Marai.)

25. Did they have a childhood best friend?

I had childhood friends, though I don’t think it wise to select from them a singular best. (She does. Her name was Dhorimyn. They’ve lost contact over the years. The last she’s heard of her, Dhorimyn had left their settlement for parts unknown.)

26. Have they had any pets?

I had a pet shark named Kadita. (They’re dead now.)

27. Did they grow up rich or poor? What were their living conditions like?

We used to move a lot when I was but a young girl. It took my parents a while to settle down in a place of our own. We were neither rich nor poor. We were in the middle.

28. What is their educational background?

I went through formal schooling, learned from the greatest mentors of my settlement, and grew into a fine sage. I learned more on my own than I did with anyone. (She’s not kidding. Her curiosity actually led to her amassing more knowledge about things outside of their settlement than the “greatest mentors” of their settlement, which were the only 10 triton scholars of their settlement.)

29. As a child, what did they want to be when they grew up?

I always wanted to be a scholar, and now, here I am. (At one point, she also wanted to be a kraken. She thought having more limbs would be efficient. She was three.)

30. What advice would they give to their younger self?

If I ever, for some strange reason, meet my younger self, I would simply tell her to continue swimming towards her current path. She will become me, and I am the best she can ever be. (We’ll agree to disagree.)

31. Growing up, were they ever bullied or were they the bully?

I was never bullied. I never bullied anyone. I just didn’t have the time. All my focus were on my studies and my research. (She was bullied. For being too absorbed in her studies. She was often referred to as the “teacher’s suckerfish” by the other children. To this day, she still thinks it was a compliment because “a suckerfish assists its host by feeding off of its parasites.” She wasn’t wrong.)

32. Who do they look up to/who is their role model?

No response. (She currently doesn’t look up to anyone, especially since she’s out of the sea and she takes to surface dwellers as subjects to study, not mentors to put on a pedestal. She used to look up to an older mentor from her settlement but he died after trying to “befriend” a female shark as a male shark, so that was that. It’s a long story, and it’s not what you think.)

PRESENT -

33. Do they currently have a place of residence?

I rented a small place for me and my...friends in Arx, at the Whale Water Port. It’s close to the water, plenty of fish, and has access to several libraries and universities. It’s the best place for me here on the surface. (Remember the kind old lady who gave her free clothes because she looked “very naked”? That became her landlady. It’s a good place for someone living “alone”.)

34. What is their most treasured possession?

My most treasured possession? I suppose the letter from my late colleague could fill this role. For now. At least until I find the answer to his question, and I will. Eventually. (She’s not as into possessions as most people are, so having a treasured...item isn’t on her radar. That should change once she gets a particular trident, though, and maybe a particular cloak and a particular decanter to boot. Maybe.)

35. What is their drink of choice?

I don’t drink that much, but I seemed to have developed a taste for the drink called Bilgewater. It reminds me so much of home. (Bilgewater is of course the bluish-brown, sometimes jet black, concoction that's made by soaking the inner organs of various sea creatures soaking in a fermented brine and then running them through a sieve to remove the bones and viscera. It's usually on most tavern's menu for at least 5 copper pieces, or you can ask your friendly neighborhood fisher to brew you one for the same price. The only real side effect of this drink it that the lingering taste of rotten, brackish seafood remains on the palette for a few hours.)

36. Which king/queen are they loyal to, if any?

None have sought me out yet, so I’m loyal to none. That should change if any reach out and we find ourselves agreeing in our principles. (So long as she get to do her research, she’s not very picky on a monarch to side with, but only if completely necessary. She’d rather not get drawn to unnecessary conflict if they can avoid them.)

37. Have they ever killed anyone?

No response. (In every attempt at progress, there will always be a casualty or two. Maybe even three. It is rarely intentional, however.)

38. What was their last promise and did they keep it?

I promised my brother I’d stay with our parents, keep them safe... (She could not keep that promise.)

LOVE -

39. What was their first kiss like, if they’ve had one?

It was...wet. And pretty sloppy. The things we do to satiate our curiosity, right? (Of course it was wet. She was underwater. It was mostly sloppy because it was their first kiss, and her “research” partner was understandably nervous, especially since she secretly liked Merrinyn. They never spoke of it again, mostly because Merrinyn concluded that it was not a fruitful experiment and Dhorimyn decided to keep her secret her own.)

40. Are they in a relationship/have a love interest?

Love is an unnecessary distraction that I cannot currently afford. (She is too busy with her research to consider a relationship, any kind of relationship, at the moment.)

41. Have they ever been in love?

Like I said, an unnecessary distraction. (She has not, though she believes she has.)

42. Have they ever had their heart broken?

No response. (Numerous times: When her pet shark Kadita passed away, when her older brother Jharvas left them in pursuit of a vampire, when she slowly lost contact with Dhorimyn, and when her favorite mentor died to sharks while in the form of a shark.)

SPIRITUALITY - 43. Do they follow a god, if so who?

I don’t follow gods. I don’t have faith in them as much as others do. I only have faith in myself, in what I can see, and in what I can prove. (That said, she does appear to admire both Habbakuk and Melora, especially the latter whose stories and lore she views as quite inspiring.)

44. What do they think happens to them after death?

I cease to exist and my body decays to join nature and the sea. That’s it. That’s all there is to it.

45. What is their spirit animal?

A kraken. Definitely a kraken. (She’s more like a dolphin, but okay.)

Today, the web application development process is not the same as it was a couple of years back. Web apps are developed using various technologies, and one of the common technologies we all might be aware of is 'Technology Stack.' It is often used in modern software development. But what does it actually mean?

Technology stack refers to the amalgamation of programming languages, tools, and frameworks used in software development. If you usually work with a tech stack, you will surely have a favorite one you always pick when developing a web application. If it is the MERN stack, you’re also one of those developers who find this technology stack the right choice to win the race in 2022.

According to the HackerRank development skill report, 30% of developers choose Angular.js while 26% stayed with React JS. The report also highlights that 30% of the programmers show interest in learning ReactJS, whereas 35.9% of developers prefer to use ReactJS for development. These stats clearly show that the MERN stack stands slightly above MEAN when it comes to popularity. Not only this, but MERN also stays on top of the chart in terms of ease of understanding.

Tagebuch: Endstress und Ahrtal

Die letzte Woche vor den Osterferien ist die schlimmste. Schlimmer noch als die Vorweihnachtswoche. Alles muss noch diese Woche erledigt werden, jedenfalls gefühlt. Zusätzlich prasseln die Anfragen rein, denn schließlich muss man auch noch diese Woche Entscheidungen für Projekte treffen, bevor alle Ansprechpartner/innen im Urlaub sind. Und versteht mich nicht falsch – ich habe so ein Rechtfertigungsgefühl – ich bin froh, viel zu tun zu haben, aber ich wäre echt froh, wenn sich der Arbeitsdruck ein wenig besser verteilte. Ein Thema, das mich schon mein ganzes Arbeitsleben begleitet, ich mache mir da keine Illusionen.

Montag, 22. März 2021

Ich hole die Kleine mittags von der Tagesmutter ab und habe dann noch gute zwei Stunden Zeit zu arbeiten, bis sie aus dem Mittagsschlaf erwacht. Um 16 Uhr habe ich eine wichtige Videokonferenz. Bis dahin kann ich mich um Klein-Lea kümmern, was ich dann auch mit Freude mache. Je näher der Termin rückt, desto nervöser werde ich allerdings. Denn ich weiß aus zu vielen Erfahrungen, dass die Kleine eskaliert, wenn sie merkt, dass ich mit anderen Leuten rede und mich nicht mit ihr beschäftige. Als um 15:55 Uhr die Kindsmutter die Wohnung betritt, rufe ich ihr ein erleichtertes „Ein Glück!“ entgegen und verschwinde in der Konferenz; die gut läuft, danke der Nachfrage.

Dienstag, 23. März 2021

Ich fühle mich nun richtig krank, wobei das so eine Erkältung ist, die einfach nur den Kopf dick macht, aber die Leistungsfähigkeit sonst nicht weiter einschränkt. Würde ich in einem Büro mit mehreren anderen arbeiten, hätte ich mich krank gemeldet, aber ich bin ja sowieso im Homeoffice. Weil ich so tapfer bin und mich nachmittags sowieso um das Kind kümmern muss, machen wir einen Spaziergang, bei dem ich zum ersten Mal meine neue kleine Drohne ausfliege. Das macht Spaß!

Irgendwo auf dem Bild versteckt sind Klein-Lea und ich

Mittwoch, 24. März 2021

Das viele Naseputzen fordet seinen Tribut. In der Nacht zum Mittwoch habe ich das Nasenbluten meines Lebens. Über eine Stunde lang bringe ich es nicht zum Stoppen. Ich bin kurz davor, den Notarzt zu rufen. Völlig entkräftet schaffe ich es aber dann doch irgendwann ins Bett. Entsprechend schlaff fühle ich mich den ganzen Tag. Was mich nicht daran hindert (hindern darf), meine Aufgabe als Moderator einer ganztägigen Veranstaltung wahrzunehmen.

Donnerstag, 25. März 2021

Bämm-bämm-bämm, es ist high noon bei den Terminen. Ich wechsle teilweise im Halbstundentakt die Videokonferenz und wundere mich nur noch, dass ich nicht alles durcheinander bringe.

Freitag, 26. März 2021

Noch einmal einen halben Tag Workshop, noch ein paar Termine und dann habe ich die stressige Phase erst einmal geschafft. Dachte ich, denn kurz vor Arbeitstagesende erreicht mich eine überraschende Nachricht, die uns ungeplante Arbeit beschert. Es wird halt nie langweilig, seufz.

Samstag, 27. März 2021

Ich schalte erst einmal – so gut es geht – ab. Die Kleine lässt uns ein paar Minuten länger als gewöhnlich schlafen und vor allem mache ich fast drei Stunden Mittagsschlaf. Das war bitter nötig. Danach geht es mir zum ersten Mal seit vielen Tagen wieder etwas besser. Leider spielt das Wetter nicht mit, deshalb komme ich nicht an die frische Luft.

Sonntag, 28. März 2021

Dafür aber heute! Wir treffen uns mit den besten Freunden im Ahrtal und laufen eine Runde den Berg hoch und wieder runter. Wie gut nicht nur das Laufen, das An-der-frischen-Luft-sein tut, sondern auch der Austausch mit echten Menschen! So lange habe ich schon auf so etwas verzichtet.

💌 Verpasse keinen Beitrag mehr! Lass dich per E-Mail benachrichtigen! 🐖 Dir gefällt, was du hier liest? Ich freue mich, wenn du Klein-Leas Sparschwein fütterst!

Getting Weird HTML URLs in Search Console Errors? https://www.reddit.com/r/SEO/comments/k0y9hh/getting_weird_html_urls_in_search_console_errors/

I've built my site with the MERN stack, and I'm getting some awfully weird URLs in my "Excluded by noindex tag"

Ex:

- https://www.(websitename.com)/ipeogzswgeb.html

- https://www.(websitename.com)/bfwobczgfutpcbgv.html

- https://www.(websitename.com)/xhegdwcxmyoik.html

I allow users to create a profile and input their own social media links, but then I preface each anchor with nofollow and noreferrer. When I attempt to go to these URLs, there's nothing there. I've reviewed my sitemap, nothing there.

IS HIRING MERN STACK DEVELOPERS MORE ECONOMICAL

A tech stack is a collection of programming languages, software tools, and development frameworks needed to create any software product, such as a website, computer software, a game, or a mobile application.

However, there are a variety of tech stacks available, but we’ll focus on the MERN Stack and its advantages.

Sources suggest that Angular JS is preferred by 30% of developers, whereas React JS is favored by 26%.

According to the research, 30% of programmers want to study React JS, and 35.9% of developers prefer to produce with it, putting MERN slightly ahead of MEAN in terms of popularity.

What is MERN Stack?

MERN Stack is a Javascript stack that makes it easier and faster to deploy full-stack web projects. The MERN Stack comprises the technologies MongoDB, Express, React, and Node.js. Its goal is to make the development process go as smoothly as possible.

MongoDB

It’s a document-oriented database with no schema. The web application’s backend is handled by a database that uses a JSON-based query language. Mongo DB, a No-SQL database, is highly adaptable and easy to use because the documents can be of various sizes, content, and fields.

MongoDB is quicker and perform better than MySQL and PostgreSQL since it does not store alike data in tables or requires field primary keys and entity keys for access.

Express.js

As required by the Node.js.HTTP module, the requirement to write repeating server code is eliminated with a web framework with a minimalistic structure for Node.js.

Its numerous capabilities and plugins work with the backend web application framework to create quick web apps and APIs.

React JS

The frontend React JavaScript package makes it easy to create HTML-based user interfaces. React is the View layer in the MVC model, with declarative views.

JavaScript, a complete-package programming language, builds repeating DOM elements, and it’s excellent for Single Page Applications.

Node.js

It’s the JavaScript runtime environment. MERN’s component, based on Chrome’s V8 JavaScript engine, uses asynchronous language.

With an efficient backend, you get faster web application development and loading times.

Benefits of the MERN Stack

Following a thorough grasp of the MERN stack’s components, we’ll go over the benefits of using the MERN stack in web application development.

No context switching

The complete program is written in JavaScript on both the client and server sides; the web application does not require context switching and provides efficient web apps.

Full-stack

You get highly compatible and robust technologies functioning tangibly together and efficiently managing client and server-side development faster with no context switching since there is no context switching.

Open Source

Because MERN is an open-source technology, it is constantly being improved worldwide. Angular JS, for example, is an open-source framework that improves coding speed and provides a plethora of tools to help you build more complicated apps faster.

Free templates

There are free templates available that can easily save you on time. Customizing a theme would have taken at least three times as long as downloading an off-the-shelf solution. If you run into any problems along the way, you’ll be able to get assistance from specialists.

Easy to use

You can quickly implement the underlying technology because it is so clearly documented. It’s easy to learn and use, making it an excellent alternative for those just starting in web development.

Cost-effectiveness

Four frameworks make up the MERN stack. If you hire G2, you won’t employ various professionals for different technologies. Using only one language saves time and money, allowing an organization to keep costs under control.

Community support

This combination of technologies has a strong community behind it, making it easier to obtain answers to any technical concerns that may arise. It reduces the time it takes to design a product, allowing you to distribute it sooner and for less money than you could with other stacks. Because of Node.js’s popularity, many people are already familiar with JavaScript; frontend programmers are familiar with CSS and HTML5.
