tsconfig.json

/*
Much of Auspice was written in JavaScript. There is an effort to convert
existing JavaScript files to TypeScript in an iterative, file-by-file approach.

TypeScript is used in this project for type-checking only, not for its compiled
output files - Babel is used for that. Config options should reflect this usage
pattern.

Visit https://aka.ms/tsconfig.json for a detailed list of options.
