# mongoose-gridfs

Forked from https://github.com/hermesdj/mongoose-gridfs 
(which is forked from https://github.com/lykmapipo/mongoose-gridfs) 
to get a runnable version that works with Mongoose >= 6.

mongoose [gridfs](https://docs.mongodb.com/manual/core/gridfs/) on top of [new gridfs api](http://mongodb.github.io/node-mongodb-native/3.1/tutorials/gridfs/)

*Note!: Only compatible with Mongoose >= 6.0.7+*

*Note!: Ensure mongoose connection before use*

## Requirements

- [NodeJS v13+](https://nodejs.org)
- [Npm v6.12+](https://www.npmjs.com/)
- [MongoDB v4+](https://www.mongodb.com/)
- [Mongoose v6+](https://github.com/Automattic/mongoose)

## Installation
```sh
$ npm install --save mongoose mongoose-gridfs
```

## Usage
```js
import { createReadStream } from 'fs';
import { createModel } from 'mongoose-gridfs';

// use default bucket
const Attachment = createModel();

// or create custom bucket with custom options
const Attachment = createModel({
    modelName: 'Attachment',
    connection: connection
});

// write file to gridfs
const readStream = createReadStream('sample.txt');
const options = ({ filename: 'sample.txt', contentType: 'text/plain' });
Attachment.write(options, readStream, (error, file) => {
  //=> {_id: ..., filename: ..., ...}
});

// read larger file
const readStream = Attachment.read({ _id });

// read smaller file
Attachment.read({ _id }, (error, buffer) => { ... });

// remove file and its content
Attachment.unlink({ _id }, (error) => { ... });
