SmartAPI JavaScript Client SDK

The `smartapi-javascript` package provides a client-side SDK for programmatic interaction with the SmartAPI platform, an initiative by Angel One (formerly Angel Broking) for the Indian stock market. It offers a comprehensive suite of functionalities, including user authentication and session management, fetching profile and real-time margin (RMS) details, executing various order types (place, modify, cancel, order book, trade book), managing portfolio holdings and positions, converting positions, and handling Good Till Triggered (GTT) orders. Additionally, it provides access to historical candle data and includes WebSocket functionality for real-time market updates. The current stable version is 1.0.27. As an official client library for a specific financial service, its release cadence typically aligns with updates to the SmartAPI platform itself. A key differentiator is its direct and tailored integration with Angel One's trading ecosystem, simplifying development for users targeting this platform. The library currently emphasizes CommonJS `require` syntax for module imports, as demonstrated in its official documentation.
