kOS Developer's Portal

Technologies

Introduction

This page enumerates the technologies (programming languages, development environments, third-party libraries) that are used when developing a kOS application.

C

C is the programming language used to develop your application’s native code.

See: Wikipedia | GCC

IDE

An IDE, or Integrated Development Environment, enables programmers to consolidate the different aspects of writing a computer program, such as editing source code, building executables, and debugging. (CodeAcademy)

You will want to use one or more common development environments to write kOS code:

Eclipse (Eclipse Foundation; Java)
IntelliJ (JetBrains; Java)
Visual Code (Microsoft; React)
Visual Studio (Microsoft; Java & React)
WebStorm (JetBrains; React)
etc.

Java

Java is the programming language used to develop your application’s backend. The kOS is build using Java 17.

See: Oracle | Adoptium | JavaDocs

JDBI

JDBI is the Java library used to access database data. It is a set of classes designed to make working with JDBC (Java database connectivity) easier.

"Jdbi provides convenient, idiomatic access to relational data in Java. Jdbi is built on top of JDBC. It improves JDBC’s rough interface, providing a more natural Java database interface that is easy to bind to your domain data types."

See: JBDI

Jetty

Jetty, an Eclipse Foundation project, provides a full-featured and standards-based web server and servlet container.

See: Jetty

JSON

JSON (JavaScript Object Notation) (pronounced "Jay-Son") is a lightweight format for storing and transporting data.

See: Wikipedia

Example JSON data

{
  "fruits": {
    "banana": {
      "color": "yellow"
    },
    "apple": {
      "color": [
        "red",
        "green"
      ]
    }
  }
}

Lombok

The Lombok Project is an annotation-based Java library that reduces boilerplate code.

See: Lombok

React

React is the programming language used to develop your application’s user interface.

See: ReactJS

REST

Representational State Transfer (REST) defines a way for network-based software applications to communicate with each other by making resources available using identifying URLs (endpoints) and HTTP methods.

See: Wikipedia | RestfulAPI | Postman

For example, here’s a way to use Twitter’s REST API to read a single tweet:

Issue an HTTP GET to the URI

https://api.twitter.com/2/tweets/{id}

where {id} is the unique identifying string. Upon successful completion of this command, an XML file is returned with the desired information.
