insure

Unobtrusive lightweight development type-checking framework

What is it?

Designed to reduce the number of type errors while developing with no changes to existing code other than the addition of type checking conditions where needed. No preprocessor or superset language dependencies required due to dynamic runtime type-checking, with the bonus of checking real-life state which implicates true support for the dynamic runtime nature of JavaScript. All this while maintaining minimal performance overhead due to the ability to dynamically disable itself in production environments without requiring the removal of type-checking conditions. This enables the ability to retain all type-checking in development environments while having it disabled in production.

It has exchangeable support for both node.js and the browser.

Insure can easily be extended with custom assertion tests which can be used to add as much power as needed for a specific project, and may extend well beyond standard type-checking while still centrally powered by insure.

Automatically supports inverted tests and or-clauses for built-in and user added assertion tests with no explicit configuration or changes needed. Add the check once for the default case and get all other functionality automatically.

Note: This is a work in progress with some key implementations remaining.
