ECMAScript Proxy Examples

Examples for my JS Roundabout talk talk about the Proxy API.

Examples

The intro directory contains examples of these traps:

• get
• set
• deleteProperty
• construct
• apply

You can run any of the below with node <directory name>:

• debugSetInterval - logging setInterval registration and clearing
• fancyConsole - a Console API-compliant proxy that augments the global console object with dates and coloured output
• lazyRequire - lazy loading of CommonJS dependencies
• memoisation - caching the output of a function based upon its input
• preventXss - preventing malicious JavaScript from being stored in a database and subsequently evaluated a HTML page
• schemaValidation - validate object properties based upon a simple schema

There is a single dependency for the preventXss example, so be sure to run npm i first.
