Use Cases
Please take a look at few workflows which might help you with deciding how you're gonna use typeorm-model-generator.
Naming strategy
If you want to generate custom names for properties in generated entities you need to use custom naming strategy. You need to create your own version of NamingStrategy and pass it as command parameter.
typeorm-model-generator -d typeorm_mg --namingStrategy=./NamingStrategy -e sqlite -db /tmp/sqliteto.db
