Deploying Node.js microservices to ZEIT ▲ Now

ZEIT Now is a cloud platform to deploy serverless applications, one of the things I like the most about Now is their DX (Developer Experience), it makes it very pleasant to deploy microservices to the cloud.

In this article we are going to learn how to install Now and start deploying with one single command, now.

Prerequisites

  • Node.js 10 LTS Installed
  • A terminal
  • Code editor of your choice
  • A ZEIT Now account, you can signup for free here

Installation

First, let’s install now CLI from npm by running the following command:

$ npm install -g now

Login

Next, we need to identify ourselves in the platform, now CLI offers an easy way to do this by running:

$ now login

This will ask for your email and will send you a Verification email, just by clicking on Verify will log you in the platform, it’s like magic 🔮!

Verifying email

Successful login from Terminal


Create your first Microservice

We are ready to start creating our first microservice (or serverless application, you name it).

Now provides a list of examples, for our exercise we are going to use Node.js ⬢, but hey!, Now supports other languages and platforms too, just give it a try with the one you like the most 😉

To start witht he Node.js template let’s run the following command:

$ now init nodejs microservice

This will create a folder called microservice with the Node.js template.

Now is time to deploy our example to the cloud, let’s go to that folder and execute now to see what happens!

$ cd microservice
$ now

Deploying to Now and running our microservice

Before continuing with our next trick, let’s explore the files we are deploying:

index.js

It contains a simple function with the request and response objects from Node.js, this will be executed on every request made to our microservice.

module.exports = (req, res) => {
res.end(Hello from Node.js on Now 2.0!);
};

index.js


now.json

It’s the deployment configuration file, used to specify the name of our project, the type of builders we are going to use, routes, etc. More information can be found in their documentation.

{
“version”: 2,
“name”: “nodejs”,
“builds”: [
{ “src”: “*.js”, “use”: “@now/node” }
]
}

now.json


Monorepo

What we have seen so far seems simple, but, here comes the real power of now, we can mix and match different microservices in a monorepo to create a full serverless project.

For our next trick, we will create a Nuxt.js static application that will be doing API requests to a Node.js microservice, both are going to be deployed to now using the monorepo approach.

Let’s create a monorepo folder and then run create-nuxt-app, this will create a basic Nuxt.js application for you, just make sure to select Axios support in the features section, we will use it later 😉.

$ mkdir monorepo
$ cd monorepo
$ npx create-nuxt-app www

create-nuxt-app

We have our frontend application almost ready, we will need to add an API to our monorepo project, let’s create an api folder and add a Node.js microservice in there (no need to create the now.json, we will take care of that later).

Let’s create a bands microservice:

$ mkdir api
$ touch api/bands.js

api/bands.js

module.exports = (req, res) => {
const bands = [
{
name: ‘Dio’,
genre: ‘Heavy Metal’
},
{
name: ‘Anthrax’,
genre: ‘Trash Metal’
},
{
name: ‘Tenebrarum’,
genre: ‘Gothic Metal’
}
]
res.end(JSON.stringify(bands))
}

yes, I like Metal 🤘

Let’s create a Deployment Configuration file to wire up our two project in the monorepo.

now.json

{
“version”: 2,
“name”: “monorepo”,
“builds”: [
{ “src”: “www/package.json”, “use”: “@now/static-build” },
{ “src”: “api/.js", “use”: “@now/node” }
],
“routes”: [
{ “src”: "/api/(.
)”, “dest”: “/api/$1” },
{ “src”: “/(.*)”, “dest”: “/www/$1” }
]
}

More information about how routes work in their documentation.

Here we are creating both the API and the Web project in one single repo using two different serverless applications, one served by @now/node and the other built by @now/static-build.

Before deploying let’s add the following to our www project:

  • Add a now-build script to the package.json file as following:
“now-build”: “API_URL=https://monorepo.julianduque.now.sh npm run generate”

This will setup Axios to discover our API endpoint in the proper URL (make sure to use your alias here), and will tell now how to generate a static site for Nuxt.

  • Let’s update our pages/index.vue page to execute the Bands microservice we implemented with Node.js
export default {
components: {
Logo
},
data: function () {
return {
bands: []
}
},
methods: {
async loadBands () {
try {
this.bands = await this.$axios.$get(‘/api/bands.js’)
} catch (err) {
console.error(err)
}
}
}
}

  • Add a Button to the <template> and render the items with Vue.js
<a v-on:click=“loadBands”>Load Bands</a>
<ul v-bind:key=“band.name” v-for=“band in bands”>
<li>{{ band.name }} - {{ band.genre }}</li>
</ul>

And voila! We have connected our two serverless applications in one monorepo with Now!

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!
