Application Programming Interface (API)

What is API?

API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other. It is a way for computers to share data or functionality, but computers need some kind of interface to talk to each other.

When you use an application on your mobile phone, the application connects to the Internet and sends data to a server. The server then retrieves that data, interprets it, performs the necessary actions and sends it back to your phone. The application then interprets that data and presents you with the information you wanted in a readable way. This is what an API is - all of this happens via API.

Building Blocks of API

There are three building blocks of an API. These are:

dataset

requests

response

Let’s elaborate these blocks a bit.

An API needs a data source. In most cases, this will be a database like MySQL, MongoDB, or Redis, but it could also be something simpler like a text file or spreadsheet. The API’s data source can usually be updated through the API itself, but it might be updated independently if you want your API to be “read-only”.

An API needs a format for making requests. When a user wants to use an API, they make a “request”. This request usually includes a verb (eg: “GET”, “POST”, “PUT”, or “DELETE”), a path (this looks like a URL), and a payload (eg: form or JSON data). Good APIs offer rules for making these requests in their documentation.

An API needs to return a response. Once the API processes the request and gets or saves data to the data source, it should return a “response”. This response usually includes a status code (eg: “404 - Not Found”, “200 - Okay”, or “500 - Server Error”) and a payload (usually text or JSON data). This response format should also be specified in the documentation of the API so that developers know what to expect when they make a successful request.

Types of API

Open APIs - Also known as Public APIs. These APIs are publicly available and there are no restrictions to access them.

Partner APIs - These APIs are not publicly available, so you need specific rights or licenses to access them.

Internal APIs - Internal or private. These APIs are developed by companies to use in their internal systems. It helps you to enhance the productivity of your teams.

Composite APIs - This type of API combines different data and service APIs.

SOAP - It defines messages in XML format used by web aplications to comunicate with each other.

REST - It makes use of HTTP to GET, POST, PUT or DELETE data. It is basically used to take advantage of the existing data.

JSON-RPC - It uses JSON for data transfer and is a light-weight remote procedural call defining few data structure types.

XML-RPC - It is based on XML and uses HTTP for data transfer. This API is widely used to exchange information between two or more networks.

Features of API

It offers a valuable service (data, function, audience).

It helps you to planabusiness model.

Simple, flexible, quickly adopted.

Managed and measured.

Offers great developer support.

Examples of API

Razorpay API

Google Maps API

Spotify API

Twitter API

Weather API

PayPal API

PayTm API

HubSpot API

Youtube API

Amazon's API

Travel Booking API

Stock Chart API

API Testing Tools

Postman - Postman is a plugin in Google Chrome, and it can be used for testing API services. It is a powerful HTTP client to check web services. For manual or exploratory testing, Postman is a good choice for testing API.

Ping API - Ping API is API testing tool which allows us to write test script in JavaScript and CoffeeScript to test your APIs. It will enable inspecting the HTTP API call with a complete request and response data.

VREST - VREST API tool provides an online solution for automated testing, mocking, automatic recording and specification of REST/HTTP APIS/RESTful APIs.

When to create an API and when not to

Its very important to remember when to create and when not to create an API. Let’s start with when to create an API…

You want to build a mobile app or desktop app someday

You want to use modern front-end frameworks like React or Angular

You have a data-heavy website that you need to run quickly and load data without a complete refresh

You want to access the same data in many different places or ways (eg: an internal dashboard and a customer-facing web app)

You want to allow customers or partners limited or complete access to your data

You want to upsell your customers on direct API access

Now, when not to create an API…

You just need a landing page or blog as a website

Your application is temporary and not intended to grow or change much

You never intend on expanding to other platforms (eg: mobile, desktop)

You don’t understand the technical implications of building one.

A question

realistically, how long will it take me to learn c++?

I started about a month ago and, tbh, I am still confused about lots of stuff (could be because i'm kinda slow). Also can anyone give me some advise to practice the stuff i'm learning? Because I don't have the slightest clue how to do it

What a better place to find help in a programming language than in a discord server… right…? Discord overall has its pros and cons but what I do like is when a genuine community is made within a server!

I’m part of 5 programming-related discord servers - I know, a lot! They each have lots a channels with different programming languages from JavaScript to C# to PHP etc. Some even have channels on career advice, coding buddies, project sharing and more! Here are the list of servers I’m in for programming!

━━━ ⋆⋅☆

💻 The Programmer’s Hangout

“If you've written 10 lines of code or if you have been writing code for 10 years, you're welcome here. The Programmer's Hangout (TPH) welcomes all levels and is a great place to get a solid footing in programming.” - [LINK] - Includes languages, tech & platforms, computer science, career & projects and off-topic channels categories!

💻 The Coding Den

“The Coding Den is a friendly community of coders focusing on helping new and experienced programmers alike.” - [LINK] - Includes JavaScript, Webdev, Graphics, Mobile, Scripting, and Systems channel categories!

💻 W3School Discord Server

“W3Schools is on a quest to make learning available to everyone - everywhere! Being active in our community will make you learn more, be more open to people, and possibly even make some friends!” - [LINK] - Includes community support and community events channel categories!

💻 Programming Discussions

“A programming community with a focus on keeping a friendly environment and learning! All skills levels welcome!” - [LINK] - Includes language-specific and topics-of-interest channel categories!

💻 Codeacademy Community

“The official Codeacademy discord server” - [LINK] - Includes Discussions, Get help and Career paths channel categories!

━━━ ⋆⋅☆

That’s it! Those are the ones I’ve stayed in the most and I enjoy the community in those servers! Obviously, I’m more active on some than others and when I’m not busy with my own work! The ones I’m most active on are Codeacademy Community and The Programmer’s Hangout! I typically stay in the HTML-CSS, JavaScript and sometimes Python related channels, other than those in the project sharing channels and general chat!

I hope this helps people cause joining these servers really helped me! If there are other discords you want to recommend, do share! That’s all so happy coding and have a nice day/night! 💻🤎

Null Stack to Full Stack

OVERVIEW

Full stack technology refers to the entire depth of a computer system application, and full stack developers straddle two separate web development domains: the front end and the back end.

The front end includes everything that a client, or site viewer, can see and interact with. By contrast, the back end refers to all the servers, databases, and other internal architecture that drives the application; usually, the end-user never interacts with this realm directly.

The easiest way to put the full stack into perspective is to imagine a restaurant. The front end encompasses the well-decorated, comfortable seating areas where visitors enjoy their food. The kitchen and pantry make up the “back end” and are typically hidden away from the customer’s view. Chefs (developers) gather permanently stored materials from the pantry (the database) and perform operations on it in the kitchen (the server), and then serve up fully-prepared meals (information) to the user.

ADVANTAGES OF LEARNING FULLSTACK DEVELOPMENT

You can master all the techniques involved in a development project

You can make a prototype very rapidly

You can provide help to all the team members

You can reduce the cost of the project

You can reduce the time used for team communication

You can switch between front and back end development based on requirements

You can better understand all aspects of new and upcoming technologies

SKILLS NEEDED

In this case, you might find various things in the internet. They all might vary. But I am keeping things simple. Among the things I am going to share, you need to focus on one stack instead of all of them. So, here are some of the skills needed to be a fullstack developer.

Front-end programming technologies: HTML, CSS, JavaScript, Angular, ReactJS, Bootstrap, jQuery, SASS, Tailwind etc.

Back-end programming technologies:Python, NodeJS, Django, Express etc.

Database: PostgreSQL, MongoDB, MySQL, etc.

Version Control System: git, GitHub, GitLab, etc

HTTPS and REQUEST Methods (GET, POST, PUT, DELETE, OPTIONS)

Now, it iis important to understand that, the basics are same for all stacks but then the technologies vary. For example the frontend can be built with either React, Angular or Vue or any other framework/library. On the other hand, the backend can be built with either of Node.js, Django (Python) or Spring Boot (Java) or any other framework. I will go to that in the coming lines.

ROADMAP / PLAN FOR THE FIRST SIX MONTHS

About this, there might be multiple other roadmaps that you can follow on your path to become a fullstack developer. I came up with the idea that this path, that I am about to share, can be a planned start to your journey with all the content structured at the right time. So, let's see the plan for the first six months.

🔵 Month 1: HTML, CSS, Javascript

The basic skills required to create a website in HTML and CSS. Javascript adds functionalities to a website and makes the project responsive. HTML is for structure and CSS for Styling. DOM Manipulation and Responsive Web Design are important to practice. Learn about these from W3Schools.

🔵 Month 2: Web Design and Frameworks, Git, HTTPs

Work on Open Source Projects. Once you have good practice with HTML and CSS you can use frameworks like Bootstrap or Material CSS which makes it easy to create websites. Alongside that, it is very important to learn about version control systems (preferrably git) so that you can save and manage your code at GitHub, GitLab, BitBucket or any other similar tool. Also, it is important to learn about HTTPS and REQUEST METHODS (GET, POST, PUT, DELETE and OPTIONS).

🔵 Month 3: Javascript Programming Language

The most important skill and most asked in Interviews and Job portals for Web Development are Javascript. You can expect a lot of interview questions from Javascript, So it's important to learn how javascript works, data structures, and asynchronous javascript.

🔵 Month 4 & 5: Frontend and Backend

Once you are thorough with the above concepts then you can take your skills to the next level by learning Javascript frameworks/libraries like React and Node JS. Point to be noted, I am a big fan of MERN (Mongo, Express, React, Node) stack, so I am always talking about React and Node. But there are other options as well.

Other options:

Frontend: Angular, Vue or any other frontend technology

Backend: Django, Flask, Spring Boot, ASP.Net or any other backend technology

Please do some research in google about the 'FULLSTACK TECH STACKS' and choose the one that you are the most comfortable with. Just a reminder, if you want to be a Java Fullstack Developer, then you need to have Java knowledge before stepping on to learning Fullstack development. Same case goes for Python, C# or any other technologies.

Most importantly, when you start learning a new technology, please start by learning from the official documentation of each individual technology. Then maybe go for other resources from the internet.

🔵 Month 6: Database and Projects

In the final month, create a portfolio and create projects using frontend and backend technologies you’ve learnt. Also, an important skill to have is knowledge of Database Management Systems like PostgreSQL, MySQL and MongoDB. Also, you need to understand how to connect the Database to Server using the backend Framework.

LEARNING RESOURCES OF FULLSTACK DEVELOPMENT

In the internet today, you can find various courses and tutorials on Fullstack development. But I know for sure that Freecodecamp website as well as YouTube channel covers all stack, so you can easily learn from them. On the other hand, there is The Odin Project. You can learn about JavaScript Fullstack Developer or Ruby on Rails Fullstack Developer. Here are the links to them.

Freecodecamp Website

Freecodecamp YouTube Channel

The Odin Project

Of course, as I said, you can look for courses in other websites as well. Here are some of the best platforms to look for courses.

Codecademy

Coursera

EdX

PROJECT IDEAS

Here are some projects that you can try when you are learning or after you have gone through all the things needed.

E-commerce website

Food delivery app

Social media app

Chat messaging app

Content management system

Project management app

Gym Tracking System

Real-time Chat App

Bug Report App

Hotel Booking App

Staff Management System

Online Store

INTERVIEW PREPS AND RESOURCES

Remember that a fullstack developer job is a vast space and thus there are many things that you need to keep focus on to ace the interviews. Here are some points where you need to take special care of for the interviews.

Javascript Programming Language and Data Structures

CSS Concepts like Flexbox, Grid, Inheritance, Specificity, etc.

React JS and new features e.g: Context API and Hooks

REST API’s and SQL and DBMS

HTTPS, Requests, Response, Servers.

Of course there are more things to focus as well, so research about the most important topics from the internet and then take special care in preparing for those questions.

Here are a few links to resources which will help you preparing for the interviews.

Coding Interview University

Interview Cake

Interview Bit

Tech Interview Handbook

Fullstack Cafe

Word of advice for newbies

Please don’t wait for people to spoon-feed you with every single resource and teachings because you’re on your own in your learning path. So be wise and learn yourself.
