What's new in this version

udpated to ZPM 0.2.1

Template repository for InterSystems IIRS REST API Programming Contest

rest-api-contest-template

This is a template for for a InterSystems IRIS REST API Contest. It has an example of REST API with CRUD actions for a Sample Person peristent class.

Inspiration

To make an easy template to start building REST API in IRIS

What it does

Creates /crud web app in IRIS and CRUD endpoints to play with persistent data in Sample.Person class. It uses swagger-ui module to provide documentation and test environment for API. rest_contest

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 ZPM

zpm:USER>install rest-api-contest-template

Installation with Docker

Prerequisites

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 git@github.com:intersystems-community/rest-api-contest-template.git

Open the terminal in this directory and run:

$ docker-compose up -d --build

How to Work With it

This template creates /crud REST web-application on IRIS which implements 4 types of communication: GET, POST, PUT and DELETE aka CRUD operations. The API is available on localhost:52773/crud/ This REST API goes with OpenAPI (swagger) documentation. you can check it localhost:52773/crud/_spec THis spec can be examined with different tools, such as SwaggerUI, Postman, etc. Or you can install swagger-ui with:

zpm:IRISAPP>install swagger-ui

And check the documentation on localhost:52773/swagger-ui/index.html

Testing GET requests

To test GET you need to have some data. You can create it with POST request (see below), or you can create some fake testing data. to do that open IRIS terminal and call:

IRISAPP>do ##class(Sample.Person).AddTestData(10)

This will create 10 random records in Sample.Person class.

You can get swagger Open API 2.0 documentation on:

localhost:yourport/_spec

This REST API exposes two GET requests: all the data and one record. To get all the data in JSON call:

localhost:52773/crud/persons/all

To request the data for a particular record provide the id in GET request like 'localhost:52773/crud/persons/id' . E.g.:

localhost:52773/crud/persons/1

This will return JSON data for the person with ID=1, something like that:

{"Name":"Elon Mask","Title":"CEO","Company":"Tesla","Phone":"123-123-1233","DOB":"1982-01-19"}

Testing POST request

Create a POST request e.g. in Postman with raw data in JSON. e.g.

{"Name":"Elon Mask","Title":"CEO","Company":"Tesla","Phone":"123-123-1233","DOB":"1982-01-19"}

Adjust the authorisation if needed - it is basic for container with default login and password for IRIR Community edition container

and send the POST request to localhost:52773/crud/persons/

This will create a record in Sample.Person class of IRIS.

Testing PUT request

PUT request could be used to update the records. This needs to send the similar JSON as in POST request above supplying the id of the updated record in URL. E.g. we want to change the record with id=5. Prepare in Postman the JSON in raw like following:

{"Name":"Jeff Besos","Title":"CEO","Company":"Amazon","Phone":"123-123-1233","DOB":"1982-01-19"}

and send the put request to:

localhost:52773/crud/persons/5

Testing DELETE request

For delete request this REST API expects only the id of the record to delete. E.g. if the id=5 the following DELETE call will delete the record:

localhost:52773/crud/persons/5

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 /src/cls/Package/Classname.cls

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