Keep Calm - Keep Coding with Cosmos and Node.js

Keep Calm - Keep Coding with Cosmos and Node.js -Coding with the Cosmos DB SDK feels good. Yes, I said feels good. Yeah, yeah … it is fast to install, fast to learn and fast to execute. But most of all it feels good.

Think about when you are coding and everything is just flowing for you. It feels great to be in a rhythm and get everything out of your head and into the code and working fluidly! A key ingredient to this is when the APIs we are coding are intuitive and easy to follow. This is where the Cosmos DB SDK shines brightest. Let’s see why.

I Want to Have Fun with the Code Now

Cosmos DB SDK is awesome, feels great, and if you want to feel great too without reading this and try this all yourself - here are the links to get you started. I may cry if you skip reading this, but I’ll get over it.

Calm, Cool, Collected Coding

When all is well with the coding universe, coding can be therapeutic for many of us. Other times it can be like a dozen screaming children running through our house with paint guns at a birthday party! (hey, don’t judge me)

When we write code we know what we want it to do. For example, recently I wanted a list of heroes from my database - just give them to me without making me work so hard! The line of code that gives them to me with Cosmos DB SDK is simply this:

container.items.readAll().toArray()


There is a container for my heroes, and it has items in it (my heroes). So read them and return them as an array, please. Now that wasn’t so hard!

Cosmos DB with Express Routes

OK, so how does this work in context with a Node and Express route for an HTTP request? Let’s think this through.

We’ll first need to set up the database. We’ll do that in another module, so we can stub that out quickly and import it.

Then we get the heroes. OK, we already have that line of code from above. This code is asynchronous, so we’ll consider using promises or async/await. It’s your call, so choose wisely. Using async/await is what brings me joy, so that’s what we’ll do here. Here is how it will look as I pull the result out and rename it heroes.

const { result: heroes } = await  container
      .items
      .readAll()
      .toArray();


Finally, if it works we need to stuff the heroes in the response with a status code. If it fails, we return a failure status code and message.

Here is the code I wrote for this. Feel free to borrow it (just return it when you’re done, please, so others can borrow it too).

//hero.service.js
const { heroes: container } = require('./config').containers;
async function getHeroes(req, res) {
  try {
    const { result: heroes } = await  container
      .items
      .readAll()
      .toArray();
    res.status(200).json(heroes);
  } catch (error) {
    res.status(500).send(error);
  }
}


That was easy. Like crazy easy! We just wrote database access code and connected it to an express route in a few lines.

OK, there was that one line we stubbed in for the configuration. We’ll need to write that, but the good news here is that the configuration only needs to be done once. The fixed cost is a one-time thing that as many functions as you need can re-use. In other words, we can write functions to get, put, post, delete heroes, villains, and whatever we want and only need that single line up top to configure it!

Isolating the Configuration

Here is a module you can use to help get started. I like to isolate the functionality that sets up my coding environment to connect to the database in one Node module. Here we have one that we could call config.js or giraffe.js. I think the former makes more sense, but you do you.

The comments explain what is happening in here, but let’s review anyway. First, we reference the Cosmos module from the @azure/cosmos npm package. Then we set up the keys, URL, and database name. This consolidates all of our configurations in one place. Finally, we instantiate the Cosmos client object and expose the container objects. These container objects are what we’ll import in other modules, so we can just ask for the container and it just works. Yes, it’s that simple.

// config.js
// Get the npm module for Azure's Cosmos
const cosmos = require('@azure/cosmos');
// Identify your database keys and name
const endpoint = process.env.CORE_API_URL;
const masterKey = process.env.CORE_API_KEY;
const dbDefName = 'vikings-db';
// Instantiate the Cosmos client object,
// which is the focal point of interacting with Cosmos
const { CosmosClient } = cosmos;
const client = new CosmosClient({ endpoint, auth: { masterKey } });
// Make it easy to acces the containers
const containers = {
  heroes: client.database(dbDefName).container('heroes'),
  villains: client.database(ddDefName).container('villains')
};
module.exports = { containers };


Try It

You can try this out yourself in your own app, or by cloning my repository here, or by running through a quick start in the documentation.

Why use Node.js for Web Development? Benefits and Examples of Apps

Front-end web development has been overwhelmed by JavaScript highlights for quite a long time. Google, Facebook, Wikipedia, and most of all online pages use JS for customer side activities. As of late, it additionally made a shift to cross-platform mobile development as a main technology in React Native, Nativescript, Apache Cordova, and other crossover devices. 

Throughout the most recent couple of years, Node.js moved to backend development as well. Designers need to utilize a similar tech stack for the whole web project without learning another language for server-side development. Node.js is a device that adjusts JS usefulness and syntax to the backend. 

What is Node.js? 

Node.js isn’t a language, or library, or system. It’s a runtime situation: commonly JavaScript needs a program to work, however Node.js makes appropriate settings for JS to run outside of the program. It’s based on a JavaScript V8 motor that can run in Chrome, different programs, or independently. 

The extent of V8 is to change JS program situated code into machine code — so JS turns into a broadly useful language and can be perceived by servers. This is one of the advantages of utilizing Node.js in web application development: it expands the usefulness of JavaScript, permitting designers to coordinate the language with APIs, different languages, and outside libraries.

What Are the Advantages of Node.js Web Application Development? 

Of late, organizations have been effectively changing from their backend tech stacks to Node.js. LinkedIn picked Node.js over Ruby on Rails since it took care of expanding responsibility better and decreased the quantity of servers by multiple times. PayPal and Netflix did something comparative, just they had a goal to change their design to microservices. We should investigate the motivations to pick Node.JS for web application development and when we are planning to hire node js developers. 

Amazing Tech Stack for Web Development 

The principal thing that makes Node.js a go-to environment for web development is its JavaScript legacy. It’s the most well known language right now with a great many free devices and a functioning local area. Node.js, because of its association with JS, immediately rose in ubiquity — presently it has in excess of 368 million downloads and a great many free tools in the bundle module. 

Alongside prevalence, Node.js additionally acquired the fundamental JS benefits: 

  • quick execution and information preparing; 
  • exceptionally reusable code; 
  • the code is not difficult to learn, compose, read, and keep up; 
  • tremendous asset library, a huge number of free aides, and a functioning local area. 

In addition, it’s a piece of a well known MEAN tech stack (the blend of MongoDB, Express.js, Angular, and Node.js — four tools that handle all vital parts of web application development). 

Designers Can Utilize JavaScript for the Whole Undertaking 

This is perhaps the most clear advantage of Node.js web application development. JavaScript is an unquestionable requirement for web development. Regardless of whether you construct a multi-page or single-page application, you need to know JS well. On the off chance that you are now OK with JavaScript, learning Node.js won’t be an issue. Grammar, fundamental usefulness, primary standards — every one of these things are comparable. 

In the event that you have JS designers in your group, it will be simpler for them to learn JS-based Node than a totally new dialect. What’s more, the front-end and back-end codebase will be basically the same, simple to peruse, and keep up — in light of the fact that they are both JS-based. 

A Quick Environment for Microservice Development 

There’s another motivation behind why Node.js got famous so rapidly. The environment suits well the idea of microservice development (spilling stone monument usefulness into handfuls or many more modest administrations). 

Microservices need to speak with one another rapidly — and Node.js is probably the quickest device in information handling. Among the fundamental Node.js benefits for programming development are its non-obstructing algorithms.

Node.js measures a few demands all at once without trusting that the first will be concluded. Many microservices can send messages to one another, and they will be gotten and addressed all the while. 

Versatile Web Application Development 

Node.js was worked in view of adaptability — its name really says it. The environment permits numerous hubs to run all the while and speak with one another. Here’s the reason Node.js adaptability is better than other web backend development arrangements. 

Node.js has a module that is liable for load adjusting for each running CPU center. This is one of numerous Node.js module benefits: you can run various hubs all at once, and the environment will naturally adjust the responsibility. 

Node.js permits even apportioning: you can part your application into various situations. You show various forms of the application to different clients, in light of their age, interests, area, language, and so on. This builds personalization and diminishes responsibility. Hub accomplishes this with kid measures — tasks that rapidly speak with one another and share a similar root. 

What’s more, Node’s non-hindering solicitation handling framework adds to fast, letting applications measure a great many solicitations. 

Control Stream Highlights

Numerous designers consider nonconcurrent to be one of the two impediments and benefits of Node.js web application development. In Node, at whatever point the capacity is executed, the code consequently sends a callback. As the quantity of capacities develops, so does the number of callbacks — and you end up in a circumstance known as the callback damnation. 

In any case, Node.js offers an exit plan. You can utilize systems that will plan capacities and sort through callbacks. Systems will associate comparable capacities consequently — so you can track down an essential component via search or in an envelope. At that point, there’s no compelling reason to look through callbacks.

 

Final Words

So, these are some of the top benefits of Nodejs in web application development. This is how Nodejs is contributing a lot to the field of web application development. 

I hope now you are totally aware of the whole process of how Nodejs is really important for your web project. If you are looking to hire a node js development company in India then I would suggest that you take a little consultancy too whenever you call. 

Good Luck!
