Template to get participants in the InterSystems Native API programming contest started

What's new in this version

Initial Release


This is a template for for an InterSystems IRIS Native API Contest. The Native API provides fast and easy access to globals and objectscript from your application.

Provided in this template is a docker file to get you started and sample programs in each supported language (Java, .Net, Node, and Python). The sample program demonstrates basic usage of the native API.

Getting started documentation

InterSystems has a number of documents on the Native API, including code examples. TheIntroduction to the Native API is a good place to start.

Contest Overview

The Native API contest seeks to find novel uses of the Native API to solve problems that are difficult to solve with SQL. Solve any sort of problem that you find interesting. You may build any sort of application so long as the build and run instructions are clear in your readme file.


You should provide a repository where docker-compose can be used to build a container image that contains Intersystems IRIS and any setup you need for your application.
You should include instructions for running your application within the docker image.

Sample programs are contained in this repository to make it easier to get started.

Each of the included examples can be built and executed in the container by running ./run.sh from their respective directories.

Template Contest Submissions


To make an easy template to start building apps using the IRIS native API

What it does

Please take some time to explain what your application does, now it uses the IRIS native API, and what makes it awesome.

Challenges I ran into

no challenges

Accomplishments that I proud of

Easy template with self documented API spec installed with one ZPM command or docker-compose build

What I learned

a lot!

Built with

Using VSCode and ObjectScript plugin, IRIS Community Edition in Docker, ZPM, IRIS openapi API

Installation with Docker


Make sure you have git and Docker desktop installed.

Clone/git pull the repo into any local directory e.g. like it is shown below:

$ git clone https://github.com/intersystems-community/native-api-contest-template

Open the terminal in this directory and run:

$ docker-compose up -d --build

How to Work With it

Start a bash shell to the container and execute run.sh

Troubleshooting Docker-Compose

If docker-compose fails, the two most common problems are:

  1. Docker version mismatch. The docker-compose specifies version 3.6. If you have a different version, you should be able to just change the version in docker-compose.yml
  2. Port unavailable. If you’re already running a container on your machine, you might need to change the port number that is exported.

How to start coding

This is a template, so you can use a template button on Github to create your own copy of this repository.
The repository is ready to code in VSCode with ObjectScript plugin.
Install VSCode and ObjectScript plugin and open the folder in VSCode.
Once you start IRIS container VSCode connects to it and you can edit, compile and debug ObjectScript code.
Open /src/cls/PackageSample/ObjectScript.cls class and try to make changes - it will be compiled in running IRIS docker container.

Feel free to delete PackageSample folder and place your ObjectScript classes in a form

The script in Installer.cls will import everything you place under /src/cls into IRIS.
