### **Note: This project is forked and a continuation of [mongo-pipeline-builder](https://github.com/MikeDev75015/mongodb-pipeline-builder). highly recommeded to check that out. Few Addons are being built upon the existing codebase**
**mongodb-aggregation-builder** is a aggregation builder for the [db.collection.aggregate](https://docs.mongodb.com/manual/reference/method/db.collection.aggregate/) method and db.aggregate method.
- Simplify aggregations by making them more readable
- Aggregations are easier to edit.
- Aggregations are testable on a dataset.
- Aggregation stages appear in an array.
- Sequential stages for documents
### `npm i -S mongodb-aggregation-builder`
## Usage:
### Using `require()`
```typescript
const AggregationBuilder = require("mongodb-aggregation-builder").AggregationBuilder;
const { EqualityPayload, OnlyPayload, Field } = require('mongodb-aggregation-builder/helpers');
const { LessThanEqual, ArrayElemAt, Equal, Expression } = require('mongodb-aggregation-builder/operators');
```
### Using `import`
```typescript
import { AggregationBuilder } from 'mongodb-aggregation-builder';
import { EqualityPayload, OnlyPayload, Field } from 'mongodb-aggregation-builder/helpers';
import { LessThanEqual, ArrayElemAt, Equal, Expression } from 'mongodb-pipeline-builder/operators';
