- tsconfig-paths
- mocha & chai
- working coverage
- fixed source maps
- fixed inspect mode
ts-node has a problem with ESM, tsconfig paths and source maps. This is a workaround for that.
To fix tsconfig paths, you need to use tsconfig-paths package and custom loader dev/loader.js.
Sadly using --loader flag in node generates warnings about experimental modules. To fix that, you need to use --import="dev/import.js" flag.
To fix source maps, you need to use --enable-source-maps flag.
To fix inspect mode while using mocha flag needs to be passed via --node-option flag.
To get coverage reports properly you need to use c8 - not nyc.
All implemented in dev/run script.
To have it all working in package scripts it would require 200+ characters :)
