1. Find module which can be resolved my issue.
2. But I could not found the module.
3. So, I developed the module.
4. Then, Considering name to publish as a library.
5. The name is already used.
6. The conflicted module is what I want to use...

Recommend to use ts-mongoose instead.

The module load typescript file as a source and output mongoose schema definitions.

npm i --save-dev ts-to-mongoose

# -s / --source: typescript file for mongoose schema definitions. You can specify glob pattern.
# -d / --dist: directory to output mongoose schema definitions.
npx ts-to-mongoose -s ${path_to_ts_file_source} -d ${dist_dir_path}

npx ts-to-mongoose -s examples/ts/**/*.ts -d examples/schema

source - TypeScript

dist - Generated Mongoose Schema
