成为后端开发者所需的技能 – 初学者路线图_AI阅读总结 — 包阅AI

In this guide, I’ll discuss the basic skills you need and steps you can take to become a backend developer.

I’ll give you a simple roadmap that’ll help you know where you are and where you should go next.

Front End vs Back End

Every website has two parts: a front end and a back end.

The front end is the part that you see in the browser and interact with. Basically, it represents all the visual aspects of a website.

The back end is the part that powers the front end. It’s behind the scenes, and it’s mainly concerned with storing and accessing data using databases, APIs, and so on.

Because of this, web development jobs fall into three main categories:

👷‍♂️What Exactly Does a Backend Developer Do?

Backend developers are responsible for constructing the foundational systems that drive the functionality of applications that users engage with.

This includes various tasks such as designing the architecture, and then implementing and maintaining these critical systems.

Their responsibilities typically involve working with:

• 💾 Databases, such as MySQL,

• ✂️ Frameworks, like Laravel or Ruby on Rails, and

• 🧨 APIs (Application Programming Interfaces).

Backend devs ensure that the backend infrastructure operates seamlessly, enabling smooth interactions between the user interface and the underlying data and processes.

Here are some of the core responsibilities of a backend developer:

• Understanding the website’s performance needs and goals

• Developing and managing APIs for the website

• Developing systems for secure data storage and processing (especially special use cases like payments)

• Writing code, testing it, maintaining it, and developing solutions to bugs

• Designing the site’s architecture using established methodologies like Agile/Scrum and various frameworks

• Organizing the system logic effectively

• Providing solutions to address system-related issues and challenges

🥷 What You Need to Know to Become a Backend Developer

Becoming a proficient backend developer requires mastering various skills and technologies.

Below, I’ve outline a comprehensive roadmap to help you achieve this goal as quickly as possible.

Just keep in mind that everyone learns at a different pace, so it’s hard to set a specific timeframe on how long this will take. Some might be able to get through it in six months or less, but others might take significantly more time.

Step 1: Foundations of Backend Development 🏗️

• Understand the role and responsibilities of a back-end developer. Familiarize yourself with databases, frameworks, and APIs.

• Join a comprehensive course on databases. Learn about SQL and relational databases like MySQL. Practice creating and managing databases.

• Learn about server-side programming languages. Start with PHP or Python. Learn basic syntax, control structures, and data types.

Step 2: Advanced Backend Concepts 🔋

Step 3: API Development and Integration 🛠️

Step 4: Troubleshooting and Optimization 🔮

• Master troubleshooting techniques. Learn how to diagnose and debug backend applications effectively.

Step 5: Cloud Infrastructure and Deployment 🌥️

Step 6: Advanced Topics and Projects 🚀

Here’s a breakdown of the tools and software commonly used in back-end development:

1. Database Frameworks:

• MySQL: A relational database management system used for storing and retrieving data. It’s widely used for web applications and offers scalability and reliability.

• MongoDB: A NoSQL database program that uses JSON-like documents with schema flexibility. It’s suitable for applications with rapidly changing data models or unstructured data.

2. Web Servers:

• Node.js: Node.js is a cross-platform (meaning it supports multiple operating systems) JavaScript Runtime Environment that uses an event-driven, non-blocking I/O model. That means it can handle a large number of users at the same time. If you already know JavaScript, Node.js will likely be your best choice for building real-time applications like chat apps, online gaming apps, and collaborative tools.

• Apache HTTP Server 2: An open-source web server software that delivers web content across the internet. It’s known for its stability, security, and flexibility, making it a popular choice for hosting websites and web applications.

  If your team is used to using languages like PHP or Python, Apache might be easier for them to work with.

• LiteSpeed: LiteSpeed is another web server software that helps websites handle lots of visitors without slowing down or crashing. It’s great for businesses that expect a lot of traffic, like during busy times. LiteSpeed also works with many programming languages like Python, Ruby, PHP, and Java.

Imagine you’re a company with 20 servers that can each handle 500 websites. Together, that’s 10,000 websites. But if you switch to LiteSpeed, you might be able to handle 20,000 websites with the same number of servers. That’s a big improvement!

When choosing a web server, it depends on what kind of website or app you’re building. If you’re just starting out, try Node.js first. It’s simple because you only need to learn one language (JavaScript) to build both the front part and the back part of your website.

4. Version Control System:

Next on your journey is to become familiar with version control systems. These systems help track project history and enable collaborative work with others.

• 🔌 Learn Git: Git is the most widely used version control system, employed by over 70% of software development teams. It’s a must-know tool, and allocating around two weeks for learning Git is advisable.

Back-end developers usually utilize these tools and software to build robust, scalable, and secure web applications that handle data storage, server hosting, and encryption of online communications.
