tws-api-nodejs-ported

NodeJS Interactive Brokers Trader Workstation API Client. Ported to TypeScript manually from official c# library.

c# sources are intentionally kept in the same folder with ported files for reference and to simplify review, updates, diff and porting.

Usage and porting notes

• when class implements Equals() function, remember to use it instead of ===, unless you really want to compare by ref for some reason.

• something == null comparison is used to test for null or undefined in one expression.

• GetHashCode() implementation does a valid hash but returns string instead of number. It is ok, because it's not used internally by js engine as it does with .net.

• private field + public getter/setter pattern is replaces with just one public field for simplicity.

• when it is safe to do so, floats are being compared with ===. Example: numbers came from a socket.

• some default values changed from null to '' or 0 or false, usage shows it's safe and it simplifies things.

• comments are preserved where it didn't require much effort, but referring to c# sources for comments is advised.

• OrderCondition modules had a nasty circular reference, fixed by merging all *Condition.ts files code into OrderCondition.ts

Testing

• some test files may seem to be useless/excessive, they've been created to include file in coverage report in case that file will get testable logic in future
