Backend tools

Programming is easier now than it was a couple of decades ago. Back then, any kind of backend development was done using manual server configurations and direct manipulation of files. It was slow, fiddly, and difficult.

Today, there are plenty of backend technologies that act as helpful shortcuts, especially integrated development environments (IDEs) like Visual Studio Code. These environments let you write, test, and debug code. They can significantly increase productivity, and reduce the likelihood of errors, because they offer things like code highlighting and auto-completion.

Code highlighting helps to visually distinguish different elements, making it easier to spot mistakes. Auto-completion speeds up coding by suggesting relevant code snippets or function names, reducing the need to remember every detail.

Just like IDEs, backend frameworks make life a lot easier for Backend Developers.

They're libraries of software that offer pre-built functions, like database integration or user authentication. A developer can easily add them to their project, instead of needing to write all of that code from scratch. Popular examples include Django for Python, and Express for Node.js. Frameworks are typically specific to a programming language, and to a certain task, such as backend or frontend development.

Backend frameworks are a massive timesaver, but they can't be used for everything. It's like buying pre-cut vegetables – they'll save you a good chunk of time in the kitchen, but you'll still need to put in the time and work to turn them into a meal.

Text editors like Sublime Text and Atom are to Backend Developers what word processing software is to the rest of us. Each language has multiple text editors available, so it’s up to the developer to pick one that works.

For example, if a developer is coding in Python and needs to work with data analysis and data manipulation tasks in a backend project, they might choose Jupyter as their development environment. Jupyter offers a range of features that are particularly useful for data analysis, making it a suitable choice for such projects.

Text editors are typically lightweight applications, which means they load quickly and consume fewer system resources compared to full-fledged Integrated Development Environments (IDEs). This makes them particularly useful for quick code editing tasks.

Local development servers, like Apache or Nginx, are another vital tool which streamline the work of modern Backend Developers.

In simple terms, these are practice areas on your local computer that replicate the conditions of a real app or website. In these practice areas, mistakes don't matter – at least, these mistakes won't break anything on the real-life (production) websites which are already visible to users.

To use a baking analogy, it's like having the chance to taste your cake before putting it in the storefront. It takes a lot of the pressure off – if your cake is burnt, you can always bake another one.

Version control systems allow Backend Developers to store each iterative version of a program, so if things go wrong in a new version, you can safely roll back to an old version.

The absence of version control systems would be like walking on a tightrope without a safety net. The risk of losing progress, or introducing irreversible bugs, would loom large.

Today’s most popular version control system is Git. It allows Backend Developers to track changes to their codebase, collaborate with other developers effectively, and easily roll back to previous versions. This makes it a powerful tool for managing complex projects.

While backend tools are helpful, they can sometimes lead to problems.

Developers may find that certain software versions are incompatible with each other, causing conflicts or errors during installation or execution. For example, if a developer is working on a Python web application, and using Django as the framework, they may encounter issues if they try to install a newer version of Django that is not fully compatible with the other libraries or dependencies in the project.

To troubleshoot this, developers will need to check the system requirements and compatibility of the software versions they are using. It isn't always easy to work it all out, but it will often pay off in the long run.

A developer’s tools are not a one-and-done setup. Over time, they'll need to keep on top of updates, or their tools will become outdated and incompatible with newer technologies and best practices.

This is known as version drift: when a tool receives updates and improvements to fix bugs, add features, and enhance security, but a user continues using an older version.

A developer should also stay on the lookout for better tools than the ones they are using now. There's a lot of redundancy in backend development, with lots of tools that do more-or-less the same thing. But there will always be minor differences, and for each of a Backend Developer's projects, one of these tools might have a slight advantage over another.
