## Introduction

TyDB is a database system written in typescript, its goal is to provide a strongly-typed database experience with an API and a query language similar to MongoDB.

* It can be in-memory, or persistent (using a persistence adapter).
* It can be used with NodeJS or in the browser.
* It can be embedded or served over a network (like MongoDB).
* The query language and the API is very similar to MongoDB, (except for the dot notation) and the difference is only to provide and experience with maximum type declaration.
* Persisted in a flat file when in node (using a persistence adapter), persisted in IndexedDB when in the browser (using another adapter), and you can easily write your own adapter too.
* Can deal with large data sets (tested against 1GB of data) and won't take too much memory.
* It is fast.
* It is light-weight (45 KB, not gzipped).
* Based on NeDB.
