Firestore didn't go well for me.

 

I decided to use my lockdown project SUDSJS.com to test out a few different NOSQL database management systems (DBMS).  

SUDSJS is written in JavaScript using the node.js server-side system and I designed it so that I could plug in different drivers for different databases. I wrote database drivers for MySQL, SQLite 3 and PostgreSQL. The first NOSQL system I tried was MongoDB, and the SUDSJS.com test site is currently running using this. The second NOSQL system I tried was Firestore from Google. 

It didn't go well.
