Creating a database from scratch with Node.js

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:

My study on how to create a database

Hello, this is the repository for my database project, I am trying to learn how to create a database from scratch using Node.js

My objective is to understand a little better how databases work internally

Installation

You need to have Node.js and NPM to install and use this project

npm i learndb

Usage

you can use this in two ways, either as an REPL or as a driver for the database

REPL

If you want to use this project as a REPL I would adivise to clone it instead of installing it, if you have it cloned, to access the REPL, all you need to do is type this on the terminal:

node index.js repl

REPL Commands

using [database name]

Either loads a database from the directory you are currently in or creates a database with the specified name if none…

View on GitHub

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
