Resource Balance Analysis is a scientific software tool for the analysis of metabolic models in Systems Biology. It is a pretty fresh and still running project of high complexity. The tool itself was written by a colleague from the Humboldt University in the programming language Python. I implemented a web interface for this tool on the basis of Node.js and Express, further configuring the user experience with Vue.js. Feel free to have a look at the construction site test server; the Institut national de la recherche agronomique in Paris and me are hopeful that this tool for the scientific community will go online in 2020.
