Full-Stack Web Development, according to the Stack Overflow 2016 Developer Survey, is the most popular developer occupation today. It’s no wonder then that there are dozens of online and in-person programs that will help people become Full-Stack Developers and then even assist these new developers land high-paying programming jobs.
Some popular online programs can be found on Lynda, Udacity, Coursera, Thinkful, General Assembly, and so much more. Aside from these online programs, there are also in-person coding bootcamps that are teaching people the skills required to become web developers.
In this article I won’t be discussing which websites or coding bootcamps have the best web development programs, instead I will be providing a definitive guide to what I believe are the most important skills required to become a Full-Stack Web Developer today and land a job if you’ve never coded before. I will be basing the list off of three things:
A combination of what most programs in 2017 are teaching students.
My own personal experiences from interviewing at companies for developer positions in the past and also interviewing potential candidates for current Full-Stack Developer positions at my current company.
Stories and feedback from people on Coderbyte who have been accepted to coding bootcamps and then proceeded to get programming jobs.
The Definitive Guide
A Full-Stack Web Developer is someone who is able to work on both the front-end and back-end portions of an application. Front-end generally refers to the portion of an application the user will see or interact with, and the back-end is the part of the application that handles the logic, database interactions, user authentication, server configuration, etc. Being a Full-Stack Developer doesn’t mean that you have necessarily mastered everything required to work with the front-end or back-end, but it means that you are able to work on both sides and understand what is going on when building an application.
If you want to become a Full-Stack Web Developer in 2017 and land your first job, below is a reference guide with a list of things you should learn.
Almost every single program, whether online or in-person, that is teaching you how to be a web developer will start with HTML and CSS because they are the building blocks of the web. Simply put, HTML allows you to add content to a website and CSS is what allows you to style your content. The following topics related to HTML/CSS come up often in interviews and on the actual job when you’re working:
Be able to explain the CSS Box Model.
Benefits of CSS preprocessors (you don’t necessarily need to understand how to use one on a deep level, but you should to understand what they are for and how they help with development).
CSS Media Queries to target different devices and write responsive CSS.
Bootstrap (a framework for helping design and layout content on a page and while many online programs or schools focus heavily on teaching Bootstrap, in reality it’s more important to have a deep knowledge of fundamental CSS than specific Bootstrap features and methods).
Some knowledge on testing frameworks and why they’re important (some may even claim that this topic should be optional).
Learn about some important new ES6 features (optional).
3. Back-End Language
Ruby: Some popular frameworks for developing in Ruby are Rails and Sinatra. Plenty of programs teach Ruby as a first back-end language.
Python: Some popular frameworks for developing in Python are Django and Flask.
Java: The Java language isn’t taught so much these days when it comes to Full-Stack Web Development, but some companies do use Java as their back-end and it is still a very in-demand language (see image above).
PHP: PHP is rarely taught in programs these days, but just like with Java, it is still very in-demand and it is a cornerstone of the web today.
4. Databases & Web Storage
When learning to build web applications, at some point you’ll probably want to store data somewhere and then access it later. You should have a good grasp on the following topics related to databases and storage.
Understand which would be better in certain situations.
Know how to connect a database with your chosen back-end language (e.g. Node.js + MongoDB).
Web storage to store sessions, cookies, and cached data in the browser.
5. HTTP & REST
Learning how to use Chrome DevTools can be extremely helpful.
What are SSL Certificates.
HTTP/2 & SPDY (optional).
6. Web Application Architecture
There are best practices that you can read about online on, but the best way to actually learn about application architecture is by working on a large application yourself that contains several moving parts — or even better, working on a team and together developing a somewhat large/complex application.
Learn about common platforms as a service, e.g. Heroku and AWS. Heroku allows you to easily upload your code and have an application up and running with very little configuration or server maintenance and AWS offers dozens of products and services to help with storage, video processing, load balancing, and much more.
Some opinions on what a web application architecture should include.
Designing Web Applications by Microsoft.
Git is a version control system that allows developers working on a team to keep track of all the changes being made to a codebase. It’s important to know a few important things related to Git so that you understand how to properly get the latest code that you’ve missed, update parts of the code, make fixes, and change other people’s code without breaking things. You should definitely learn the concept behind Git and play around with it yourself.
Here’s a reference list of some common git commands you’ll likely use.
Here’s a tutorial on using Git and GitHub for beginners.
8. Basic Algorithms & Data Structures
This topic is somewhat polarizing in the development world because there are developers who don’t think there should be such a heavy focus on computer science topics like tree traversal, sorting, algorithm analysis, matrix manipulation, etc. in web development. However, there are companies like Google that are notorious for asking these types of questions in their interviews. As someone said about the Front-End engineering interview at Google:
That said, as Ryan McGrath mentions, our front-end (FE) engineers are expected to have a solid CS background, like all our engineers.
While there are companies that practically require applicants to have a computer science degree or equivalent, there are plenty of companies that will hire people without this technical qualification if they can prove that they know how to develop applications and show an understanding of the whole domain. But part of being a competent developer and not writing inefficient code or using the wrong tools is an understanding of some basic algorithms and data structures and being able to analyze trade-offs. So here are some things you should definitely learn:
Understand how trees and graphs can be beneficial as data structures.
Know when to use an object vs an array and understand the trade-offs.
Learn the difference between queues and stacks.
It’ll be hard work learning all of this, but it’s rewarding in the end and Full-Stack Development is fun! Leave your comments below, and check out Coderbyte for some algorithm practice.
