Development

Web application development

This process creates software applications made accessible through the Internet and on which users can interact via their Web browser.

The keys to a robust web application

Whether an application will be used by a huge B2C audience or by an internal business unit for a very specific need, it needs to follow a certain number of good practices to ensure a seamless experience for the user. We work both at a micro level, to meet the features acceptance criteria, and also at a high level, to make sure the application is robust, fast, and secure. Web development includes front-end and back-end developments which are performed by Osedea's full-cycle developers. Actions that can be taken to ensure robustness depending on needs include:

  • Offer a neat responsive experience on every targeted device
  • Monitor and improve performance to respect the constraints (number of concurrent users, maximum time responses, etc.)
  • Analyze and process data to exploit relevant datasets
  • Use external services to connect with highly specific technologies (e.g. payment platforms) that aren’t directly related to the business domain of the application
  • Implement Single-Page Applications (SPAs) to enhance navigation through the application without loading whole new pages [this technology is widely used for SaaS (Software as a Service) products]
  • Set up Server Side Rendering (SSR) to speed up loading and optimizing SEO
  • Ensure a high level of accessibility by respecting the WCAG (Web Content Accessibility Guidelines) standards
  • Limit the environmental impact of the application by adopting green software engineering best practices
  • Guarantee quality and facilitate maintenance by covering the codebase with unit and integration tests
  • Secure the application by respecting standards and recommendations (such as OWASP), and monitoring the application

Our web development tech stack

  • React is an open-source JavaScript library developed by Facebook that facilitates the development of web applications with highly interactive user interfaces.
  • Angular is an open-source platform developed by Google and based on TypeScript. It facilitates the development of web applications with highly interactive user interfaces.
  • Python is a programming language popular within the scientific community thanks to its simple syntax that is easy to learn. It’s supported by a strong community and is particularly adapted for data analysis and complex calculations. It’s also become one of the most used languages for backend development.
  • Java is one of the most-used programming languages for enterprise software. Its robustness and portability make it a good choice for complex enterprise software that may be installed on-site. Spring, the world’s most popular Java framework, makes programming Java quicker, easier, and safer for everybody thanks to its focus on speed, simplicity, and productivity. Reactive systems have certain characteristics that make them ideal for low-latency, high-throughput workloads. Project Reactor and the Spring portfolio work together to enable developers to build enterprise-grade reactive systems that are responsive, resilient, elastic and message-driven.
  • Since 2009, the Node.js platform has been one of the most popular tools for backend development. Its success is partly due to the fact that it uses JavaScript language, which is very popular among the developer community.
  • TypeScript is a language built on top of JavaScript to add strong typing. It adds expressiveness to the code and makes it possible to detect errors early in the development phase.
  • WebXR is the successor to WebVR, it enables fully-immersive 3D scenes for VR and AR. It's extremely flexible as it can run on both mobile devices and VR headsets. It can be embedded into existing web applications with relative ease.
