The Growing Demand for Backend Developers

These days, more and more companies need to hire talented backend developers. A backend developer writes all the behind-the-scenes code that powers websites and mobile apps. Front and back end developers make sure things run smoothly for the user.

So why is this job getting popular? Well, as more apps and online services appear, skilled backend devs become invaluable. Their work supports great user experiences.

What Does a Backend Developer Do?

Backend code handles a lot of technical tasks, like:

• Connecting apps and websites to databases;
• Writing APIs for different services to communicate;
• Running key operations on servers;
• Ensuring speed, security and reliability.

Without solid backend infrastructure, the front-facing parts of apps wouldn’t function!

In-Demand Skills

To be an effective back end and front end developer, certain coding languages are good to know:

• Java
• JavaScript (Node.js)
• Python
• PHP.

Also vital is understanding databases, servers and networks.

Being skilled in these areas lets skill back end developers adapt as technology changes too! Knowing multiple languages makes them versatile.

More Jobs on the Way

The U.S. Bureau of Labor Statistics forecasts 13% growth for all software developers from 2020 to 2030. And the backend to frontend niche should see especially high demand.

As companies rely more on web apps and cloud computing, they’ll need hire a backend developer. Startups need them when launching new products as well.

With development know-how and problem-solving ability, backend developer skills promise strong job security. Experience level can range from jr backend developer to senior positions too.

Backend Development Services: Getting Started

Beginning programmers can access many online backend developer coursera courses and tutorials nowadays. Building a portfolio of personal coding projects is hugely valuable.

Backend end work may not seem glamorous, but companies rely on backend software enjineers big time! Patient learners who gear up with logical thinking and in-demand skills can access exciting and stable careers.

The backend code behind millions of apps keeps improving lives. And talented backend developers for hire will always be needed to create what’s next!

Basic Programming Concepts

Learning to code means understanding some key ideas that all programs use. It can seem tricky at first, but taking it step-by-step makes it easier!

Data Types

All back end programming languages have something called data types. These allow you to work with different kinds of data in your code. Some examples are:

• Text – Called a “string”. Let’s you use words and sentences.
• Numbers – Called “integers” and “floats”. Integers are whole numbers like 10 or 5000 and floats have decimals like 10.5 or 3.6579.
• True/False – Called “Booleans”. Helps make decisions.

When writing code, you have to be clear which data type you want to use.

Variables

Now what about storing data in your programs so you can use them? This is where variables come in handy!

A variable allows you to take a data type like a string and give it a name. For example, myName = “Lucy” creates a string variable called myName and stores the text “Lucy” inside it.

You can then use myName throughout your code instead of typing “Lucy” everywhere! Variables help keep data organized and programs easy to update.

Conditionals

Often, you want your program to make simple yes/no or true/false decisions and respond differently. Conditionals let you do this!

The basic building block is an if/else statement:

if (condition is true) {

// execute this code

} else {

// execute other code

}

So for example:

if (myName == “Lucy”) {

print “Hello Lucy!”

} else {

print “I don’t know who you are!”

}

Will display different text based on the variable value. Pretty cool huh?

Loops

No one likes repetitive tasks. That’s why loops exist! They allow you to repeat chunks of code efficiently.

The two most common types are for loops and while loops. A for loop runs code a set number times, for example:

for (i = 0; i < 5; i++) {

print i

}

Will display 0 1 2 3 4.

A while loop runs code over and over as long as some condition stays true. Say you want your user to guess a number from 1-10. You could do:

secretNum = 5

guess = 0

while (guess != secretNum) {

// ask for another guess

}

// they guessed correctly!

The while loop runs the guessing code until the guess matches secretNum. Lovely!

Functions

Finally, functions bundle code so you can reuse it easily. Define a function once:

function sayHi(name) {

print “Hello ” + name

}

And reuse it by calling sayHi(“Lucy”) whenever you want! Functions keep your programs organized.

So in summary – mastering these coding basics helps any backend in programing get started! They form the building blocks for writing all kinds of handy scripts and programs. Start small, practice slowly, and most importantly – have fun with your new superpower!

Working with Databases

Databases are at the heart of most modern web and mobile apps. They organize and store data for efficient searching and processing. Mastering some database basics helps backend developers build a website with database backend and create great user experiences.

SQL and NoSQL

Databases are containers that store information for websites and apps. Database backend development helps organize user data like profiles, messages, products, payments, and more. Different kinds of backend databases for websites work differently behind the scenes.

The two main database types that backend developers work with are called SQL and NoSQL:

SQL Databases:

These rely on predefined structures like spreadsheets to arrange the data. Information gets organized neatly into tables of rows and columns. For example, a users table with columns for name, email, age, location etc. Each user’s data goes into the rows. SQL stands for “Structured Query Language” – this allows developers to access and work with the structured data using simple commands (queries). Some popular SQL databases are MySQL, Oracle, PostgreSQL.

NoSQL Databases:

These databases are more flexible and less structured. Instead of rows and columns, data gets stored in documents or as key-value pairs for example. The formats can vary depending on the kind of NoSQL database used. NoSQL handles big amounts of data well. Some examples are MongoDB, Cassandra, and Redis. The data is easier to scale across many servers.

Here’s a simple table comparing the two main database types:

So in a nutshell, SQL gives more control over organized data while NoSQL offers flexibility with large amounts of data! Backends leverage both database types.

Queries in SQL Databases

As mentioned, SQL databases for backend development store data in structured tables with rows and columns, similar to spreadsheets. To manipulate and access this data, developers use SQL statements – which means Standard Query Language. This is a special programming language for querying and managing data in SQL databases.

Some common SQL queries that backend developers need to know include:

SELECT – This retrieves existing data from a database table that matches certain provided criteria. For example:

SELECT name, age FROM users WHERE age > 30

This query would go into the “users” table, select just the “name” and “age” columns from rows where the age value is over 30. The result is those users names and ages.

INSERT – This query lets you insert or add new data into a database table. You would specify the table name and then values for each column in parentheses. Like:

INSERT INTO users (name, age, email) VALUES (“Samantha”, 25, “[email protected]”);

This adds a new user “Samantha” with age 25 and email into the users table.

UPDATE – If you need to update or change existing data in a database, the UPDATE query lets you do that. You set new column values and filter with a WHERE clause to update specific rows.

DELETE – Does what is sounds like, deleting rows from a database table based on a condition. Dangerous if not careful!

So in summary, SQL queries allow developers to get, add, update or delete data in SQL databases programmatically. These basic CRUD (create, read, update, delete) operations form the foundation working with structured SQL data.

Database Relationships

SQL databases shine when you connect and combine data from different tables.

For example, say you have a “customers” table and an “orders” table. You want to connect customers to their orders.

To link them, you add a “customer_id” column in both tables. Then rows storing data about a particular customer in the customers table can be connected to rows about their orders in the orders table.

The “customer_id” column in each of those related tables becomes a “foreign key”. This lets you bring data together in queries by matching on those keys, like:

SELECT c.name, o.order_details

FROM customers c, orders o

WHERE c.customer_id = o.customer_id

And voila! You can now easily view joined customer and order data in SQL results.

The process of dividing databases into multiple related tables using foreign keys and joins is called database normalization.

It helps avoid duplicating data across tables. So all customer info goes in the customer table just once. This keeps databases fast, lean and easier to maintain.

To concluse this, relating tables via keys enables combining relevant data from different places as needed. And splitting bigger tables prevents multiple messy copies of the same data. Database normalization through careful division with relationships powers many huge backends!

NoSQL Flexibility

Unlike SQL databases, NoSQL databases do not rely on heavily structured data models. Developers have more flexibility with how they choose to store and represent information.

For example, NoSQL databases work well with data formats like JSON (JavaScript Object Notation) documents. JSON uses simple key-value pairs, lists, and other nested structures familiar to programmers.

So rather than needing a rigid database schema with rows and columns like this:

Table: Users

Columns: name, age, email

A NoSQL “users” collection may store flexible JSON documents like:

{

“name”: “John”,

“age”: 27,

“hobbies”: [“coding”, “baseball”, “reading”],

“address”: {

“street”: “123 Main St”,

“city”: “Anytown”,

“state”: “CA”

}

}

Much less strict! Each user document can have varying fields and nesting.

This flexibility allows developers to rapidly evolve applications without heavy database administration and migrations. New user attributes can easily be added across documents later if needed.

NoSQL databases also natively support scalable Big Data applications dealing with loads of unstructured data from social media, sensors, chat logs etc. These endless floods of information are easier to ingest.

So in summary, NoSQL provides far fewer data schema restrictions and more adaptability than SQL databases. This allows backends to focus efforts on app coding rather than database modeling!

Scaling and Sharding

As apps and data grow rapidly, databases need to scale across multiple servers through sharding – distributing subsets of databases across many machines.

NoSQL databases horizontally scale with relative ease. But SQL servers can also leverage Read Replicas and database partitioning to handle bigger workloads.

So in summary, from simple queries to complex cloud data at scale – mastering databases is crucial for backend masters!

Backend API Development: Application Programming Interfaces (APIs)

What’s an API? API stands for Application Programming Interface. Don’t let the complex name scare you! APIs are simple concepts that connect computer programs to share data and functionality.

Connecting Frontends and Backends

A common use of APIs is linking a frontend to a backend, for example in backend API for mobile apps. The frontend is the part of a website or app the user sees. The backend stores data and runs behind-the-scenes.

APIs allow these two sides to communicate securely.

For example, think of a weather app. The frontend displays the 5-day forecast. But it fetches that weather data from an API connected to a backend database.

REST APIs

There are different types of APIs. One popular style is called REST (Representational State Transfer).

REST APIs allow basic data operations using simple requests:

• GET – Retrieve data
• POST – Submit new data
• PUT – Update existing data
• DELETE – Delete data

The frontend weather app would GET data from the backend weather API.

Making API Calls

Frontend code uses libraries like JavaScript’s fetch() to make API calls. You target endpoints like:

Copy code

https://api.weather.com/v2/forecast?city=chicago

This asks the weather API for Chicago data. The API returns data, usually in JSON format for easy parsing.

API Status Codes

APIs also include helpful status codes that indicate request outcomes:

• 200s – Success!
• 300s – Redirection
• 400s – Client-side error
• 500s – Server-side error

For example, 404 means a requested endpoint or resource wasn’t found on the API. Super useful for debugging!

Security Principles

When building apps and websites, security is extremely important. Developers use various methods to protect user data and prevent attacks. Learning core security principles helps keep backends safe.

Encryption

Encryption encodes data so only authorized parties can read it. Data gets scrambled into ciphertext only decryptable with a secret key.

Many websites use SSL (Secure Sockets Layer) encryption for traffic between servers and browsers. The little “https://” padlock gives peace of mind!

Access Controls

Controlling access limits functionality. Some users may only view content, others can add, edit, or delete it.

For example, an admin gets full app access whereas standard users have restrictions. Permissions and roles help segment what different user types can do.

Authentication

To grant access, users must authenticate their identities. Common methods:

• Username & passwords
• Oauth via Google/Facebook etc
• Multi-factor authentication (MFA) requiring extra codes

Choosing secure authentication options is an important piece of access control.

Threat Protection

Despite best efforts, backends still face threats like:

• SQL injection (malicious SQL code snippets)
• XSS (dangerous JavaScript injected into sites)
• DDoS attacks (overloading servers)

Validating and sanitizing all frontend user inputs protects against common attacks like SQLi and XSS by removing harmful snippets.

Staying Vigilant

Incorporating encryption, rigorous access controls, authentication, and attack protections makes developing secure backend systems easier.

But it’s an ongoing process as new threats always appear. Continued education, testing defenses, and collaborating with ethical hackers helps keep backends secure against ever-evolving risks.

No backend connected to the internet is 100% impenetrable, but the right blend of tools, protocols, and vigilance comes close!

Testing and Debugging

Creating complex programs like backend web development systems inevitably involves squashing bugs. Rigorous testing and debugging helps developers write stable, reliable code users can trust.

Testing Code

Testing code thoroughly is crucial so bugs don’t reach real users. Backend website development systems involve a lot of critical flows – data validation, storage operations, API calls etc. Errors in production can be expensive!

Some key testing methods help:

• Unit Tests – Test individual functions automatically to check they behave as expected with different inputs. Catch basic issues early.
• Integration Tests – Test combined frontend + backend flows to confirm real-world functionality works pre-launch.
• Test Automation – Scripts to repeatedly test major site areas against regressions.
• Testing takes patience but pays dividends in less firefighting down the line!

Debugging Issues

But when bugs inevitably crop up, debugging helps investigate errors and exceptions raised by code failures.

Debugging tactics include:

• Logging – Print out variable values during code execution to check status.
• Breakpoints – Pause running code mid-execution to peek inside program logic step-by-step looking for divergence.
• Error Reporting – Services like Sentry aggregate errors from users to highlight bad code areas.

Modern front end back end developer tools have evolved to assist debugging from browsers to IDEs like Visual Studio.

Healthy Mix

Writing perfect code immediately takes mythical skill levels! Combining solid testing procedures, debugging know-how, and developer tools support helps create the reliable backend foundations users appreciate.

A culture focused on code quality and support for squashing bugs makes all the difference when battling the inevitability of defects in complex backend systems. Prevention + remediation provides the best path forward!

Bridging the Gap Between Frontend and Backend

Modern web and mobile applications require seamless collaboration between frontend and backend development. While these roles have distinct responsibilities, effective communication between them is vital. By bridging knowledge gaps, prioritizing shared goals, and choosing compatible technologies, teams can deliver cohesive final products.

Understanding the Division

Frontend developers deal directly with everything application users see and interact with. This client-side code handles design, layout, and responsive UX/UI components.

Backend enjineers instead maintain behind-the-scenes technology powering core application functionality. Servers, databases, APIs, business logic rules, and data modeling all fall under their domain.

With such different focuses, friction can emerge unless the roles align closely throughout projects.

Finding Common Ground

Product and project priorities should be clearly defined from the start and apply evenly to those working on frontend and backend tasks. Smooth handoffs between completed development phases relies on unified targets.

Likewise, promoting knowledge sharing helps entire teams visualize final data flows from databases and servers all the way through APIs to user-facing features. Discussing pain points and keeping colleagues in the loop avoids nasty surprises.

Choosing Compatible Technologies

Ideally, stacks and architectures are agreed upon early so that chosen programming languages, frameworks, and infrastructure don’t conflict.

For example, frontend JavaScript should pair symmetrically with Node.js on the backend for fast communication and JSON manipulation. Modern tech combinations keep projects coherent.

Specialized Skills Bridging

In smaller teams, front end back end full stack developers may still be required to handle some tasks outside their typical domain. Multi-skilled coders can bridge specialized knowledge gaps when providing peer training opportunities.

Backend coders may explain SQL query nuances while frontend coders demonstrate responsive design principles, for instance. Cross-training empowers smaller teams.

Staying in Sync

Consistent daily stand-ups and weekly reviews encourage alignment. Constructive criticism, early warning of blockers, and demos of new features keep everyone on the same page.

At the end of the day, seamless front end and back end coordination relies on forging strong collaborative partnerships across development specialties. Building bridges enables the delivery of elevated digital experiences.

Python and Node.js for Backend Web Development

Building the backend – the behind-the-scenes inner workings – of websites and web apps requires specific languages that can interact with servers, databases and other technology. Two popular and capable options beloved by many developers are Python and Node.js.

Both are open-source programming languages with large, supportive communities. For fledgling or experienced coders, they provide accessible starting points into backend web development along with rock-solid capabilities for large-scale solutions.

Prefer microservices breaking apart monolithic architectures? Node works wonders for independent services orchestrating in harmony.

How about machine learning paired with hefty data visualizations? Python data science servers feeding real-time dashboard frontends via Node suits perfectly.

When used individually or jointly, Python as backend and Node developed talents unlock backend magic while keeping accessibility and joyful coding core. Building brighter Python backend development catalyzes better user experiences!

Python Backend with React Frontend

When structuring modern web applications, it’s common to “split” the project into two sides – the frontend and the backend. The frontend is what the users sees and interacts with in the browser using HTML, CSS and JavaScript. The backend involves servers, databases and programming logic running behind the scenes.

A popular tech pairing is to create a Python-based backend system with a React frontend. Here’s an overview:

React Frontend: React is a popular JavaScript framework for building fast, dynamic browser-based user interfaces. React components allow crafting robust UIs that can display updated data instantly as it changes over time. This helps create smooth, responsive feelings during browsing.

Python Backend: On the flip side, Python is cherished by developers for its readable syntax and huge ecosystem of handy libraries covering data science, web frameworks, automation scripts and more. For backends, Python can connect to databases, process uploads, handle requests and render data seamlessly.

Playing to Strengths: Together, React and Python complement each other perfectly. React offers crisp client-side UI rendering tucked behind a flexible Python backend crunching numbers, serving saved assets or connecting via APIs to external services.

Developers can build awesome front-facing functionality with React  best backend while Python handles the heavy backend lifting. Assigning complementary tasks to each technology keeps projects fast yet stable.

For small prototypes or giant platforms alike, combining Python backend for React UI reactive speed enables stellar web applications. Happy coding!

Hiring a Java Backend Developer – What to Look For
