When considering enrolling in a coding bootcamp, you may wonder what awaits you on the other side and how your future role and responsibilities will shape up.
A front-end developer is also responsible for ensuring that their code runs on all devices seamlessly and adapts to the screen size, browser, and operating system. It is very frustrating when you struggle to look up information on a website and see the layout does not fit on your screen. Front-end developers have to ensure their code is usable on mobile devices, which is now prioritized by many companies.
- HTML and CSS are the building blocks of any web application to support the layout, typography, and responsive design. These are the core blocks of how your website will look, with it you set parameters for headings, font, colors, and formatting.
- Git: a version control system used by developers to manage code and collaborate on projects. It helps many engineers to merge their code into a single project and avoid conflicts. Front-end engineers must understand how to use Git and its related tools such as GitHub, Bitbucket, or GitLab.
- Testing and debugging with frameworks like Jest, Mocha, or Jasmine, and debugging tools like Chrome DevTools.
Examples of job titles: front-end developer, front-end software engineer, front-end engineer, React engineer. Average salary: $84,462, according to Glassdoor.
Back-end developers focus on the server-side infrastructure of a web application, ensuring that the application is not just a “facade” but stores, processes, and shows data efficiently. They design and maintain databases, handle API requests, and develop server-side logic.
For example, when you book a flight online, the backend engineering ensures you receive the correct results, allocate a vacant seat, and checkout with a preferred fare. It also stores your personal data, generates invoices, e-tickets, and handles online check-in.
Back-end developers are responsible for creating and maintaining databases and APIs that enable communication between the front-end and back-end of an application. They use frameworks and libraries such as Node.js, Express.js, and MongoDB to build scalable, secure, high-performing back-end systems. Back-end developers are also responsible for structuring the application, implementing authentication and authorization mechanisms, and handling server-side validation and error handling.
They work closely with front-end developers, designers, and project managers and play a crucial role in building and delivering applications that are efficient, secure, and provide an exceptional user experience.
- Databases: a back-end developer must have a strong understanding of databases and data modeling, the core of storing and retrieving information about services, items, and users.
- REST API: to be able to design and implement RESTful APIs that enable communication between the client-side and server-side applications. In other words, call data from the back end to show on the front end.
- Express.js: Express.js is a popular Node.js framework for building web applications and RESTful APIs. It’s used to save time in programming in Node.js, thanks to its ready solutions.
- Git: Version control is a must for back-end developers to write and maintain quality code.
- Testing and debugging: Like all good software engineers, back-end developers must have experience with testing and debugging techniques.
Examples of job titles: back-end engineer, back-end software engineer, back-end developer, NodeJS engineer, NodeJS developer. Average salary: $111,256, according to Glassdoor.
Full-stack developers bring together the best of both worlds: they have the skills to work on an application's front-end and back-end aspects. This comprehensive skill set makes them invaluable in small teams and startups, where resources may be limited.
- Designing and implementing end-to-end features for web applications.
- Ensuring seamless integration between front-end and back-end components.
- Collaborating with other team members to develop, test, and deploy new features.
- Troubleshooting and optimizing application performance.
It is truly beneficial to have the abilities of a full-stack engineer, as by learning one language, you can work on both front-end and back-end code, making you more versatile and efficient. Your ability to work across the entire development process will make you an invaluable asset, especially in early-stage startups and smaller teams.
