@barchart/portfolio-api-common

AWS CodeBuild NPM

A public library of shared JavaScript code used by Barchart's paper-trading portfolio system.

Overview

Simply put, this project contains code that runs on both the servers (i.e. Serverless applications) and clients (e.g. browser, mobile, etc).

/lib/serialization

Data is passed between client and server in JSON format. However, the code works with more complex types. For example, Decimal instances are used in place of native JavaScript floats and Day instances are used instead of native JavaScript Dates.

So, before data is exchanged, it must be converted to pure JSON. Conversely, when data is received, as pure JSON, its translated into more complex types before use. This is facilitated by the Schema definitions which build custom "reviver" functions for JSON parsing.

/lib/processing

For reporting and display purposes, positions can be grouped together (by asset class, by portfolio, by user, etc). This code supports aggregation and gain/loss calculation. It is used by server-generated reports and dynamic user interfaces.

Notable Consumers
