Examples

• Creating model from local MSSQL database
  • Global module

    typeorm-model-generator -h localhost -d tempdb -u sa -x !Passw0rd -e mssql -o .
    

  • Npx Way

    npx typeorm-model-generator -h localhost -d tempdb -u sa -x !Passw0rd -e mssql -o .
    

• Creating model from local Postgres database, public schema with ssl connection
  • Global module

    typeorm-model-generator -h localhost -d postgres -u postgres -x !Passw0rd -e postgres -o . -s public --ssl
    

  • Npx Way

    npx typeorm-model-generator -h localhost -d postgres -u postgres -x !Passw0rd -e postgres -o . -s public --ssl
    

• Creating model from SQLite database
  • Global module

    typeorm-model-generator -d "Z:\sqlite.db" -e sqlite -o .
    

  • Npx Way

    npx typeorm-model-generator -d "Z:\sqlite.db" -e sqlite -o .
    

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
