# mongoose-to-csv-quotes

MongooseToCsvQuotes is a mongoose plugin that creates a [`CsvBuilder`](https://github.com/nickpisacane/CsvBuilder) instance for your Schema. Updated [`mongoose-to-csv`](https://www.npmjs.com/package/mongoose-to-csv) package that escapes commas by default. Only if options.show_headers is true, are headers put in first row.

## Usage

```js

const mongooseToCsvQuotes = require('mongoose-to-csv-quotes') 

var UserSchema = new mongoose.Schema({

  fullname: {type: String},

  email: {type: String},

  age: {type: Number},

  username: {type: String}

});

UserSchema.plugin(mongooseToCsvQuotes, {

  headers: 'Firstname Lastname Username Email Age',

  alias: {

    'Username': 'username',

    'Email': 'email',

    'Age': 'age'

  },

  virtuals: {

    'Firstname': function(doc) {

      return doc.fullname.split(' ')[0];

    },

    'Lastname': function(doc) {

      return doc.fullname.split(' ')[1];

    }

  }

});

var User = mongoose.model('Users', UserSchema);

// Query and stream

User.findAndStreamCsv({age: {$lt: 40}})

  .pipe(fs.createWriteStream('users_under_40.csv'));

// Create stream from query results

User.find({}).exec()

  .then(function(docs) {

    User.csvReadStream(docs)

      .pipe(fs.createWriteStream('users.csv'));

  });

// Transform mongoose streams

User.find({})

  .where('age').gt(20).lt(30)

  .limit(10)

  .sort('age')

  .stream()

  .pipe(User.csvTransformStream())

  .pipe(fs.createWriteStream('users.csv'));

```

## Installation

```sh

$ npm install mongoose-to-csv-quotes

```

## Testing

Running tests requires a local mongodb server, and mocha. While most likely not a namespace issue, the test script will create a database `__mongoose_to_csv_test__`, and drop the database when finished. You have been warned.

```sh

$ npm test

```

## API

#### Schema.plugin(mongooseToCsvQuotes, options)

The `options` argument is passed to the `CsvBuilder` instance, please refer to

the Docs for more in-depth details. The only aditional property that can be included is the `virutals` property.

The `virtuals` have nothing to do with mongoose virtuals.

### Schema.csvReadStream([docs])

Creates a csv formated read stream from query results.

* docs Array

### Schema.csvTransformStream()

Transforms mongoose querystreams to csv formated streams.

### Schema.findAndStreamCsv(query)

* query Object Mongoose query

This is just a convenience method for:

```js

Schema.find(query).stream().pipe(Schema.csvTransformStream())

```
