Return DB results from a function in a different file (React Native/Typescript + SQLite)

I'm trying to read data in one file from an SQLite database and return it to display in a different file.

Firstly, I'd like to be able to manipulate the data prior to displaying it, for example, return the results into an array I can loop through, run some calculations, then update the rows. Secondly, I'd like to display it in the component, but I can't even seem to do that.

I have a TSX file where I store my CRUD functions. Here's my read one that I want to call from a different file:

export const ReadSingleProject = (projectID: string) => {    SQLite.openDatabase({    name: "database.db",    createFromLocation: "~database.db",    location: "Library",  }).then((db) => {    db.transaction((tx) => {      tx.executeSql("SELECT * FROM projects WHERE projectID=?",        [projectID],        (tx, results) => {          var len = results.rows.length;          if (len > 0) {                      return results.rows.raw();          }        }      );    })      .catch((error: string) => {        console.log(error);      })      .then(() => {        db.close().catch((error: string) => {          console.log(error);        });      });  });};

And then in my component file, I'm simply trying to bring in the results:

useEffect(() => {     let project = ReadSingleProject(projectID);   }, []); 

But this 'project' object comes back saying undefined. I've tried splitting the results into a JSON object in File 1 and returning that to populate a JSON object File 2, but there doesn't appear to be any data, even though when I console log in File 1, the results are there correctly.

Could anyone help, please?

Thanks
