Hey folks!

This is my first attempt at creating my own database from scratch. I am doing this for learning purposes and so I can say I have a database named after me;

Currently, in the first day of development, my main resource to study is this post, but I will not be doing a SQL database, instead, I will follow his steps but try to create a document database, like MongoDB

On this first day, my data is only stored in memory, I haven't yet started to work on the data persistency (actually saving it to disk).

Today I have implemented three functions:

Create

creates a new table; The current syntax for this function is:

Create [table name] [args...]

Example:

Insert

adds a document to a table; the current syntax for this function is:

Insert [table name] [args...]

Example:

Select

either returns each document for a table or the structure for the entire database; the current syntax for this function is:

Select [table name (optional)]

Examples:

So yeah, this is what I've managed to create today, I will keep on improving it tomorrow and probably post about it after Christmas.

If anyone wants to try it or just to take a peek at source code, this is the GitHub repository for it:

npm i learndb

node index.js repl

And to run it, you just need to have an updated version of Node.js and write the following command in its root directory:

node index.js
