PoloDB is a embedded JSON-based database.

[中文版](README_CN.md)

# Features

• Simple/Lightweight/Easy to learn and use

• Various languages binding

• Embedded(No standalone processes, no cross-process calls)

• No runtime dependency

• NoSQL

• MongoDB-like API

• Cross-Platform

• Store data in ONE file

# Introduction

PoloDB is a library written in Rust that implements a lightweight [MongoDB](https://www.mongodb.com/).

PoloDB has no dependency(except for libc), so it can be easily run on most platform(thanks for Rust Language).

The data of PoloDB is stored in a file. The file format is stable, cross-platform, and backwards compaitible.

The API of PoloDB is very similar to MongoDB. It’s very easy to learn and use.

# Platform

Theoretically, PoloDB supports all platforms that Rust compiler supports. But PoloDB is a personal project currently. Limited by my time, I only compile and test on the following platform:

• macOS 10.15 x64

• Linux x64 (Tested on Fedora 30)

• Windows 10 x64

# Manual

• [Rust](./docs/en-US/Rust/READEME.md)

• [Node.js](./docs/en-US/Node.js/READEME.md)

• [Python](WIP)

# Developing Plan

The feature will be implemented one by on in order.
