What Tech Trends Will Shape Software Development in 2019?

Big Trends

Progressive Web Apps (PWAs) now support offline operation, home‑screen installation and push notifications, narrowing the gap with native mobile apps. Chatbot platforms and frameworks are maturing, moving from novelty to routine automation. Cloud computing is becoming ubiquitous as AWS, Google Cloud and Azure lower costs, making cloud resources accessible to small teams and individual developers. Machine learning continues rapid growth, driven by high‑profile successes such as AlphaGo and expanding open‑source ecosystems.

Frontend Development

Two major web platform advances—WebAssembly and Service Workers—enable fast, efficient web applications and richer offline capabilities. Angular 2 (Google‑maintained, written in TypeScript) provides a full‑stack solution for web, desktop and mobile. Vue.js 2.0 combines ideas from Angular, React and Ember while remaining lightweight. Ember offers stable, backward‑compatible features and automatic template updates. Bootstrap 4 (alpha) introduces a card component and Flexbox‑based grid. SASS and LESS remain the leading CSS preprocessors, offering mixins, functions and better code organization.

Backend Development

Node.js now fully implements the ES6 specification, enabling fast API servers, desktop apps (Electron, NW.js) and bots. Popular frameworks include Express, Koa, Next and Nodal. PHP continues to thrive with frameworks such as Laravel, Symfony and Zend 3. Ruby on Rails 5.0 adds WebSockets and API support; Sinatra 2.0 targets smaller services. Python offers Django 1.10 (full‑text search for PostgreSQL, middleware improvements) and Flask for lightweight services. Java developers can choose Play, Spark or combine with Scala; Java 9 (upcoming) adds a REPL, HTTP/2 support and new APIs. Elixir with the Phoenix framework aims to match Rails performance while leveraging Erlang’s concurrency.

Databases

PostgreSQL 9.5/9.6 introduce UPSERT ( ON CONFLICT), improved full‑text search and parallel query execution for terabyte‑scale workloads. MySQL 8.0 (forthcoming) brings major performance and feature enhancements. CouchDB provides a scalable JSON store with a RESTful API; PouchDB enables offline syncing in browsers. Redis remains a fast key‑value store with rich data structures and an upcoming module system in version 4.0.

Programming Tools

Yarn (Facebook) is a deterministic, faster alternative to npm while remaining compatible with package.json. Visual Studio Code and Atom are the most popular open‑source editors, offering extensible linting and refactoring plugins. Git is the de‑facto version‑control system; platforms such as GitHub, GitLab and Bitbucket facilitate repository sharing. Docker and Ansible support DevOps practices for rapid, reliable deployments. Electron and NW.js allow developers to build cross‑platform desktop applications using web technologies.

Technology Trends

Cloud migration accelerates as enterprises adopt AWS, Google Cloud or Azure, making cloud deployment a valuable skill. Artificial intelligence gains traction through open‑source libraries like TensorFlow and Microsoft Cognitive Toolkit, enabling voice recognition, image classification and other ML workloads. Virtual reality (Oculus Rift, Daydream, Windows Holographic) and augmented reality platforms mature, though challenges such as motion sickness remain.

Programming Language Updates

JavaScript : ES2017 introduces async/await; Babel enables use in all browsers.

TypeScript 2.1 (late 2018) adds async/await support for older browsers and improves type inference.

C# 7.0 (expected 2020) brings language enhancements and .NET Core cross‑platform support.

Python 3.6 (released Dec 2018) solidifies its role for automation, web development, ML and scientific computing; PyPy offers JIT‑accelerated performance.

Ruby 2.3 (early 2018) includes performance gains; Ruby 3 aims for three‑fold speed improvements.

PHP 7.1 (Dec 2018) builds on 7.0’s performance gains for fast web applications.

Java 9 (expected 2020) adds a REPL, HTTP/2 support and new APIs; Kotlin and Scala remain viable JVM alternatives.

Swift 3 (early 2018) simplifies iOS/macOS development; Swift 4 (Sept 2019) adds server‑side capabilities.

Learning Recommendations

Focus on one or more of the following areas to stay current:

Frontend: Angular 2, Vue.js 2.0, Ember, Bootstrap 4, SASS/LESS.

Backend: Node.js (Express/Koa/Next), PHP (Laravel/Symfony), Ruby on Rails, Python (Django/Flask), Java (Play/Spark) or Elixir/Phoenix.

Databases: PostgreSQL, MySQL 8.0, CouchDB/PouchDB, Redis.

Tools: Yarn, Git, VS Code/Atom, Docker, Ansible, Electron/NW.js.

Emerging tech: Cloud platforms (AWS/GCP/Azure), AI/ML libraries (TensorFlow, Cognitive Toolkit), VR/AR development.
