Browser Frontend by SNOMED International

This is a generic browser front end project, specific instances used in the IHTSDO browsers are customized in branches of this project.

The browser connects to a backend REST API provided by the project: https://github.com/IHTSDO/snowstorm

Project Structure

The index.html includes all the logic for rendering the Browser UI, switching between different SNOMED CT releases and UI layouts (perspectives).

bootstrap-custom: folder that contains a custom build of the Boostrap framework
css: stylesheets for this site
external-libs: js libraries used by this site
snomed-interaction-components: js, css and fonts for the SNOMED CT widgets contained in this site
img: images for the site
i18n: internationalization files for the site and the widgets
index.html: one page application

Internationalization

This project uses the jquery-i18n-properties plugin to support internationalization, translation of the UI components to many languages. (https://github.com/jquery-i18n-properties/jquery-i18n-properties)

The i18n folder includes the base language file (/i18n/Languages.properties), this files defines the labels for English language:

i18n_app_name = IHTSDO SNOMED CT Browser
i18n_release = Release
i18n_perspective = Perspective
i18n_about = About
i18n_provide_feedback = Provide feedback on this browser

In other files, that include the ISO language code in the name, the labels are translated, like:

Languages_es.properties (Spanish)

i18n_app_name = Navegador de SNOMED CT 
i18n_release = Edición
i18n_perspective = Perspectiva
i18n_about = Sobre
i18n_provide_feedback = Proporcione sus comentarios sobre este navegador

Languages_da.properties (Danish)

i18n_welcome = Velkommen
i18n_app_name = IHTSDO SNOMED CT Browser
i18n_release = Udgivelse
i18n_perspective = Visning
i18n_about = Om
i18n_provide_feedback = Send en kommentar om denne browser

Local configuration, build and run the browser locally

Local configuration

Run npm install to make the local application aware of your grunt installation.

Build

The Grunt default task will create all these components, running grunt in the root folder of the project will build all widgets and create the distribution files.

js
- internal-libs/snomed-interaction-components.min.js
css
- css/snomed-interaction-components.min.css

Run locally

In order to obtain api-endpoint information within the local environment, a configuration similar to the following should be used:

user 'details here';
worker_processes  1;
 
events {
    worker_connections  1024;
}
 
http {
	include    mime.types;
    server {
		listen		8080;
		server_name	localhost;

    location / {
      root /FileLocation/sct-browser-frontend/;
    }       
    
    location /snowstorm/ {
      proxy_pass https://dev-browser.ihtsdotools.org/snowstorm/;
    }
	}	
}

URL Shortcuts

The browser includes URL parameters that will act as shorcuts for opening the browser with pre-defined settings or content selections, skipping the need of selecting options from the main view.

Or you can just jump to running the following command, replacing the <host> variable with the full URL to your snowstorm instance:

docker run --name snowstorm-nginx -d -p 80:80 --env API_HOST=<host> snomedinternational/snomedct-browser
