The Growing Importance of APIs

The use of APIs has exploded in recent years as software architecture has evolved to be more distributed and modular. Instead of large monolithic codebases, modern applications are often composed of many smaller services that communicate via APIs.

Consider these statistics that highlight the prevalence of APIs in today‘s tech landscape:

  • There are over 24,000 public APIs listed in the ProgrammableWeb API directory as of 2023, with many more private APIs used internally by companies.

  • API calls represent over 80% of all web traffic according to recent data from Akamai.

  • By 2025, the global API management market is projected to grow to $22.14 billion, a 27% increase from 2020 (Source: Statista)

  • A 2022 report from RapidAPI found that 96% of developers expect to increase their API usage in the coming year, with most planning significant growth.

  • According to a global survey by Postman, API development is a key priority, with 89% of organizations having dedicated API teams and plans for active investment.

What‘s driving this rapid growth in API adoption? A few key factors:

  1. Cloud Computing and Microservices – As more companies move their infrastructure to the cloud and adopt microservice architectures, APIs become the glue that connects these distributed systems. Cloud providers like AWS, Azure, and Google Cloud all offer extensive API services.

  2. Mobile and IoT Devices – APIs provide a way for the ever-growing array of mobile apps and connected devices to access data and functionality from servers and other systems. APIs make it possible to build rich experiences across a range of platforms.

  3. Digital Transformation – Businesses in all industries are undergoing digital transformation to operate more efficiently and better serve customers. APIs enable new workflows, automation, and data-driven decision making by allowing different software systems to work together.

  4. Software Ecosystems – Forward-thinking companies are opening up their software platforms and data to outside developers via APIs. This allows third parties to build integrations and add-ons, increasing the value of the core product. Think of all the apps built on the Facebook or Shopify API.

The ubiquity of APIs means that being able to work with them is no longer optional for most developers. Let‘s look at why API skills are especially relevant for programmers like the ones Cory teaches in his book and courses.

Why API Skills are a Must for Self-Taught and Early Career Programmers

Understanding APIs is valuable for programmers of all experience levels, but it‘s especially crucial for those just starting out or transitioning into software development from non-traditional backgrounds. Here‘s why:

  1. APIs are Everywhere in Modern Software Development – As the data shows, APIs are now involved in the majority of software projects. Bootcamp grads and self-taught programmers are likely to encounter them in their first jobs and projects.

  2. APIs Enable Practical Development Skills – Being able to read API docs, make HTTP requests, handle JSON payloads, etc. are highly practical skills that developers use every day. Practicing with APIs helps new programmers build confidence in their ability to solve real problems.

  3. APIs Make Impressive Portfolio Projects Possible – Integrating APIs allows newer programmers to build applications that would be far too complex and time-consuming to code entirely from scratch. Leveraging existing APIs is a great way to ship portfolio projects faster to showcase your skills to potential employers.

  4. API Experience Helps You Get Hired – A recent analysis of over 100,000 programmer job listings by CoderPad found that APIs were one of the top 5 skills mentioned, ahead of topics like data structures and algorithms. Hands-on API projects can make you a competitive candidate even without a traditional CS degree.

  5. APIs Often Bridge Knowledge Gaps – Many self-taught and bootcamp-educated programmers have gaps in computer science fundamentals compared to university grads. APIs provide a way to use complex functionality without having to fully implement it yourself. They let you grow your skills gradually while still building meaningful applications.

As Cory Althoff explains in his book "The Self-Taught Programmer" (which is almost entirely focused on building projects and gaining practical skills):

"It‘s so important to start building projects as early as possible. Reading books and completing coding exercises is a great way to learn programming languages and computer science concepts, but it‘s making real applications that cements your skills and teaches you how to think like a software engineer. Nothing is better for your coding abilities than using APIs, designing systems, and debugging your own code."

In short, API knowledge acts as a force multiplier for new programmers looking to make their skills more practical and impactful in the shortest time possible. Especially if you‘re trying to land your first programming job, demonstrating API projects can help convince employers of your readiness to contribute from day one.

Getting Started with APIs

If you‘re newer to programming, some of the API concepts we‘ve covered might sound complex or intimidating. Rest assured that APIs are very learnable even for relative beginners. With some practice and support from the developer community, you can start using them in your projects sooner than you might expect.

Here are some resources to continue your API learning after the workshop:

  • FreeCodeCamp‘s APIs and Microservices Certification – A hands-on approach to learning API fundamentals and building API projects using node.js and the Express framework.

  • The Official Django REST Framework Tutorial – A great starting point if you‘re interested in building APIs with Python and the popular Django web framework.

  • Codecademy‘s Create a Back-End App with JavaScript Course – An introduction to APIs and back-end programming for those with some front-end JavaScript knowledge.

  • The GitHub API Docs – GitHub has one of the best-documented and extensive APIs out there. A great place to practice making real API requests.

  • Postman API Platform – Industry-standard tools for testing, documenting, and publishing APIs. Very useful when you start creating your own.

Remember that you don‘t need to have every concept mastered before you dive in and start experimenting. As Cory advises:

"Find an API that looks interesting to you and try to build a small project with it. Follow the documentation and don‘t be afraid to make mistakes. Some of the best learning happens when you get stuck and have to find a way through it."

Learn APIs, Change Your Programming Future

Ultimately, taking the time to learn about APIs isn‘t just about gaining another technical skill. It‘s about opening up new possibilities for what you can create as a programmer and accelerating your journey to becoming a professional software developer.

In the words of Cory Althoff:

"Learning about topics like APIs can feel overwhelming, but remember that every programmer was once in your shoes. The key is to not psych yourself out and just keep putting in the steady practice. Amazing things start to happen when you build a project that can interact with an API – it‘s like adding rocket fuel to your capacity to bring ideas to life. It might just be the thing that helps you get to the next level and land your dream programming job."
