<h3 align="center">AvionDB: A Distributed, MongoDB-like Database</h3>

### Architecture

![AvionDB Architecture](https://raw.githubusercontent.com/aviondb/aviondb/master/assets/Architecture.png)

AvionDB uses OrbitDB stores to model MongoDB-like Databases. It creates a notion of:

- Each AvionDB instance can have several [Databases](https://github.com/dappkit/aviondb-specs#databases).
- Each Database can have several [Collections](https://github.com/dappkit/aviondb-specs#collections).
- Each Collection can have several [Documents](https://github.com/dappkit/aviondb-specs#documents).

See more details in the [Specs](https://github.com/dappkit/aviondb-specs).

### Project status & support

Status: **in active development**

**_NOTE!_** _AvionDB is **alpha-stage** software. It means AvionDB hasn't been security audited and programming APIs and data formats can still change. We encourage you to [reach out to the maintainers](https://discord.gg/88YpNuQ) if you plan to use AvionDB in mission critical systems._

This is the TypeScript implementation and it works with **Browsers**, **Node.js** & **TypeScript** with support for Linux, OS X, and Windows . The minimum required version of Node.js is now 8.6.0 due to the usage of `...` spread syntax. LTS versions (even numbered versions 8, 10, etc) are preferred.

## Install

This module uses node.js, and can be installed through npm:

### Using NodeJS

```
// Using npm
npm install --save aviondb

// Using Github
npm install git+https://github.com/dappkit/aviondb.git
```

We support both the Current and Active LTS versions of Node.js. Please see [nodejs.org](https://nodejs.org/) for what these currently are. The minimum required version of Node.js is now 8.6.0 due to the usage of `...` spread syntax. LTS versions (even numbered versions 8, 10, etc) are preferred.

### In a web browser

#### **through Browserify**

Same as in Node.js, you just have to [browserify](http://browserify.org/) to bundle the code before serving it.

> Note: The code uses `es6`, so you have to use [babel](https://babeljs.io/) to convert the code into `es5` before using `browserify`.

#### **through webpack**

Same as in Node.js, you just have to [webpack](https://webpack.js.org/) to bundle the the code before serving it.

> Note: The code uses `es6`, so you have to use [babel](https://babeljs.io/) to convert the code into `es5` before using `webpack`.

#### **from CDN**

Instead of a local installation (and browserification) you may request a remote copy of AvionDB from unpkg CDN.

To always request the latest version, use the following:

```html

<script src="https://unpkg.com/aviondb/dist/aviondb.min.js"></script>
```

CDN-based AvionDB provides the `AvionDB` constructor as a method of the global `window` object. Example:

```javascript
// create an AvionDB instance
const aviondb = await AvionDB.init("DatabaseName", ipfs);
```

**See [examples/index.html](./examples/index.html) to check out a fully functioning example for AvionDB with browser.**

## Usage

**We are upgrading AvionDB to newer versions of `js-ipfs`. For now, please use js-ipfs@0.44.0**

### Example

```javascript
// Import modules
import AvionDB from "aviondb";
import IPFS from "ipfs";

const runExample = async () => {
  const ipfs = await IPFS.create();

// Creates a db named "DatabaseName" in the ".aviondb" directory in the project root.
  // If no path option is defined, $HOME/.aviondb is used for the database directory (e.g. "C:/Users/John/.aviondb" or "~/.aviondb").
  const aviondb = await AvionDB.init("DatabaseName", ipfs, {
    path: "./.aviondb",
  });

// Returns the List of database names
  await AvionDB.listDatabases();
  // prints ['DatabaseName']

// Creates a Collection named "employees"
  const collection = await aviondb.initCollection("employees");

// Returns the List of collection names
  await aviondb.listCollections();
  // prints ['employees']

// Adding an employee document
  await collection.insertOne({
    hourly_pay: "$15",
    name: "Elon",
    ssn: "562-48-5384",
    weekly_hours: 100,
  });

// We also support multi-insert using collection.insert()
  // See https://github.com/dappkit/aviondb/blob/master/API.md

// Search by a single field Or many!
  var employee = await collection.findOne({
    ssn: "562-48-5384",
  });

// We also support find(), findById()
  // See https://github.com/dappkit/aviondb/blob/master/API.md

// Returns the matching document
  console.log(employee);
  // Prints the above added JSON document

// Update a document
  var updatedEmployee = await collection.update(
    { ssn: "562-48-5384" },
    { $set: { hourly_pay: "$100" } }
  );

// We also support updateMany(), findOneAndUpdate()
  // See https://github.com/dappkit/aviondb/blob/master/API.md

// Returns the updated document
  console.log(updatedEmployee);
  // Prints the updated JSON document

// await collection.close(); // Collection will be closed.
  // await aviondb.drop(); // Drops the database
  // await aviondb.close(); // Closes all collections and binding database.
  // await ipfs.stop();
};

runExample();
```

## Frequently Asked Questions

### Are there implementations in other languages?

We are working to implement AvionDB for following languages:

- NodeJS & Browser JS
- Typescript
- Golang
- Rust

The best place to find out what is out there and what is being actively worked on is likely by asking in the [Discord](https://discord.gg/88YpNuQ).

If you want or are planning to create an implementation in a language that is not listed here, then feel free to reach us out and discuss about it in the [Discord](https://discord.gg/88YpNuQ).

### Where can I see your Roadmap?

You can find our Roadmap [here](https://github.com/dappkit/aviondb/issues/10). The features in the Roadmap are taken from 2 separate issues([#7](https://github.com/dappkit/aviondb/issues/7), [#8](https://github.com/dappkit/aviondb/issues/8)) which individually maintain a list of feature proposals related to OrbitDB-specific improvements & AvionDB-specific improvements respectively.

The Roadmap is an open discussion, feel free to add your suggestions, comments.

### What mongodb features does aviondb support?

You can find all the supported MongoDB-like features in our [API docs](https://github.com/dappkit/aviondb/blob/master/API.md).

### How can I use AvionDB in my Application?

You can see the following examples to get started with AvionDB:

- [**aviondb-p2p-sync**](https://github.com/dappkit/aviondb-p2p-sync)

A TodoList example using showing how you can sync/replicate AvionDB data across multiple devices. In this example, we synced a todolist from a desktop browser to a mobile browser using a QR Code.

- Check out the app [here](https://bit.ly/aviondb-p2p-sync)
  - Check out the code [here](https://github.com/dappkit/aviondb-p2p-sync)

- [**aviondb-firebase**](https://github.com/dappkit/aviondb-firebase)

An example using Firebase for AvionDB Access Control. In this example, we used Firebase email/password authentication as an Access Control for AvionDB (a distributed, MongoDB-like database). So, if you would try to write to AvionDB without logging in, the database will not allow you to do so internally.
