Hey folks!

This is my second entry on my "devlog" for my database project, today I've started working on the data persistency and in the parsing of more complex inputs (strings with more than one word).

New functionalities

• Data persistency: now whenever I call the command "using" or "create" or "insert" the database is writing itself to disk with the .ldb extension (it is still a JSON, I just made this so it would not keep triggering the nodemon whenever I made a change to any table)

Example:

• Parsing strings with multiple words: in yesterday's version it wasn't possible to pass parameters with multiple words, now I've made a custom parser that supports it

Example:

Code structuring changes

First of all, I've cleaned some of my code, the parser file was getting way too big, so I moved some things around, this is my new structure:

• commandExecutor: holds references for each command
• database: returns the memory instance of the current database, allows me to set it to a new value, and saves the database
• parser: transforms the input string into an array of commands and parameters

and the commands folder holds a file for each possible command:

Conclusion

loving to work on this project, I didn't even mean to write about it again before Christmas, but I was so happy with this morning's results that I could not wait

and again, this is the repository for this project, if anyone wants to check it out:
