1) I need to map csv files into text files
2) I need to read blob data from sqlite3 file
Further details will be given later. Start the your proposal by naming the libraries you will use to parse the csv files and query the sqllite3 database.
I'm working professionally with NodeJs thus the parsing and mapping csv files and reading sqlite db does not represent any issue for me. The only nodejs libs needed here are csv-parse and sqlite3.
