Ermac is an embeddable GUI of the MPDS platform. It allows browsing the MPDS scientific data from any website or integrating the MPDS GUI into the existing codebases.
Ermac is completely free software. Upon compilation it's just a few static web assets. Copy these files to your web-server in a subfolder and enjoy your own MPDS platform. The data stays at the MPDS server.
An arbitrary static web-server is required, e.g. python -m http.server or php -S localhost:5555 or npm i -g http-server && http-server or whatever. All the content is static. In the development mode, the code is served from the src_js folder. In the production mode, the code in src_js should be compiled into a bundle ermac.min.js, which is then served. See example_dev.html and example_prod.html correspondingly.
git clone https://github.com/mpds-io/ermac
cd ermac
# then run your static web-server and open it in a web-browser
Ermac is just a thin browser client (with a little fat). From whatever physical location, it talks to the MPDS platform servers at the api.mpds.io domain. Beware, Ermac employs the old-style JQuery-fashioned ES5 JavaScript (see src_js folder). The Node and npm are intentionally NOT used. Several external dependencies are supplied simply along with the codebase in third_party and src_js/third_party folders. For future, we consider re-implementation of this codebase in the modular TypeScript framework. Please contact us if you'd like to know more or help.
Compilation into the production bundle ermac.min.js from src_js is done via the Google Closure Compiler supplied in third_party/jscomp folder, see deploy/build_js.sh script. For that you need a Java Runtime Environment (JRE), i.e. a command java -version should not produce an error in your terminal. On a typical Unix, such as Debian, JRE is installed e.g. like this:
apt-get -y update && apt-get -y upgrade
apt-get install default-jre
java -version
Given your JRE works, compilation is done as follows:
bash deploy/build_js.sh
The resulted file ermac.min.js is to be included into your webpage (see example_prod.html). Alternatively, see Ermac demo which is just a repository branch gh-pages compiled by GitHub action and served at the custom domain.
