Naše technologie

Android

Naši Android vývojáři vyvýjí plné úsilí k tomu, aby respektovali a dodržovali pravidla pro Material Design a nástroje designu poskytnuté společností Google.

Java 1.0 was released in 1995 and is still being used widely today – in part because of Android. Being an old language the toolchain is mature, and features like annotation processing, instant-run and an excellent Java SDK provide a nice toolset for development.

Android Studio is the natural choice for the platform with all the bells and whistles it brings. Android Studio plugins
android-butterknife-zelezny – Generate view bindings from the XML file directly
Markdown support – Preview the markdown layout directly in AS

Android has an excellent selection of available libraries for everything. These are some of the tools we use on a day-to-day basis. We always use the latest official design and appcompat libraries from Google as well.

  • OkHttp – An HTTP+HTTP/2 client for Android and Java applications.
  • Retrofit – Used together with OkHttp as a “frontend” for API interfaces
  • OkHttp Logging interceptor – Great logging for quick HTTP debugging

Swift

We’ve started with Swift as soon as version 1.0 was released and since then we have migrated all our projects through Swift 2 up to Swift 3 and we make sure all our frameworks and dependencies support all versions of the language.

Objective-C

Objective-C is a thing of the past for us, but occasionally we do maintain projects or update applications still written in Objective-C

Nodes utilises the full power of Apple’s own IDE; XCode. We are always testing the newest frameworks and OS features in Apple’s beta versions of XCode so we can beat potential bugs before Apple roles it out.

iOS has an excellent selection of available libraries for everything. These are some of the tools we use on a day-to-day basis. We always use stable branches and MIT licensed frameworks that doesn’t go against Apple’s Guidelines.

Vapor –  Server Side Swift

Vapor is the most used web framework for Swift. It provides a beautifully expressive and easy to use foundation for your next website or API.

Nodes have a full system setup for supporting and maintaining Vapor Server Applications, and have already produced Vapor Server Applications for large corporations in industries such as pharma, aviation, transportation and financial.

Laravel – PHP

Laravel is a web framework that are build in PHP. Nodes have been developing application with Laravel since late 2013 and have since then been our top choice of runtime compiled server development framework.

Nodes have developed large scale server applications that have supported 1.000.000+ users from different industries, countries and with an array of different services added to it.

Vapor

Nodes utilises the full power of Apple’s own IDE; XCode. We are always testing the newest Swift versions and features in Apple’s beta versions of XCode so we can beat potential bugs before Apple roles it out.

Laravel

Nodes utilises the power of PhpStorm for developing Laravel projects. PhpStorm performs many routine tasks right from the IDE and enables Nodes Server Side developers to faster and more typesafe develop Laravel projects.

General about Stack

All of Nodes server stack components are based on free-ware without any licensing. Nodes have picked some of the most commonly used stack components for the reasons of

  • Support & Community – Easy for Nodes to find talent to work within the scope of the technology and large knowledge base for help and support for maintenance
  • Flexibility – Server components useable with most commonly used web technologies so Nodes doesn’t lock themselves on one type of web / server development
  • Stability – Tried and tested on millions of projects and implemented by millions of developers. Active teams working on updates

Stack / Tools

  • Linux – is the most common OS for web servers in the world. Nodes have been using it since 2008
  • Docker –  is a new generation of virtualisation (from 2013) that makes building complex software stacks much easier and more isolated than previously
  • Nginx / Apache is the two most common web servers for Linux
  • MySQL – is an open source Relational Database started in 1995 and today owned by Oracle. We also have experience with forked versions like MariaDB or Aurora
  • Redis is an open source in-memory data structure store. We mainly use it for caching and as session driver
  • S3 file storage – is used to upload and manage data
  • Cloudfront CDN with Image resizing – is Amazon’s CDN which job is to cache public files on local high load servers
  • Beanstalkdis needed to offload the work to a queue system. Beanstalkd is our technology for this
  • ElasticSearchNoSQL Database, often used for very advanced search queries.
  • MongoDBNoSQL database, often used for aggregating big data sets

Multiplatformní vývoj

Pokud jde o multiplatformní vývoj, je zde velký potenciál a výhody, ale také rizika a výzvy. Tyto multiplatformní nástroje používáme, jsou-li pro specifické projekty vhodné a zároveň pravidelně testujeme a porovnáváme mezi sebou různé struktury.
