    Mongo aggregation pipeline

    This module provide a nice way to work with aggregations of mongodb using, for example, the mongoose in nodejs.

    Basic example

    const mongoose = require('mongoose');
    const { PipelineBuilder } = require('mongo-pipeline');
     
    const pipeline = new PipelineBuilder();
     
    const collection = await pipeline
      .match({ _id: mongoose.Types.ObjectID('xxxxxxxxxxxxxxxxxxx') })
      .lookupAndUnwind('collections', 'field', '_id', 'new')
      .log()
      .aggregateOneWith(mongoose.model('Collection'));
    /*
    [
      {
        $match: {
          _id: 'xxxxxxxxxxxxxxxxxxx'
        }
      },
      {
        "$lookup": {
          "from": "collections",
          "localField": "field",
          "foreignField": "_id",
          "as": "new"
        }
      },
      {
        "$unwind": {
          "path": "$new"
        }
      }
    ]
    */
