JavaScript issues we fix before deploying
Common JavaScript problems that affect Cloudflare Pages deployments.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
Loose equality comparisons
Using == instead of === leads to type coercion bugs where '0' == false, null == undefined, and other non-obvious truthy/falsy comparisons cause silent logic errors.
Unhandled promise rejections
Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.
Global variable leaks
Missing 'const' or 'let' declarations create implicit globals that pollute the global scope and cause unpredictable behavior across modules.
Cloudflare Pages deployment issues we check for
Common Cloudflare Pages problems that break JavaScript apps in production.
Workers runtime missing Node.js APIs
AI-generated server code uses Node.js built-ins (Buffer, fs, crypto) that don't exist in the Cloudflare Workers runtime, causing build or runtime errors.
Function invocation limits exceeded
Free tier allows 100,000 function invocations per day. AI-generated SPAs that use functions for every API call burn through limits quickly in production.
KV namespace not bound in wrangler.toml
AI tools reference KV storage in code but forget to declare the KV namespace binding in wrangler.toml, causing undefined binding errors at runtime.
Request body size limited to 100MB
Cloudflare Workers have a strict 100MB request body limit. AI-generated file upload handlers don't implement chunked uploads, failing on larger files.
