This article explains SPA architecture and build steps—transpiling, bundling, and minification/obfuscation—and how these complicate analysis while outlining methods to de-minify and debundle code (e.g., using JSNice and understanding Webpack internals). It then highlights security implications of modern frameworks, noting React's reduced XSS surface by default and potential CSP bypass opportunities via Angular-specific gadgets.
