@typescript-eslint cannot parse file without TypeScript
This error occurs when ESLint is configured to use @typescript-eslint/parser with type-aware linting (parserOptions.project), but tries to lint a file that isn't included in your TypeScript configuration. Files must be in your tsconfig.json's include array or you need to adjust ESLint's configuration to exclude them.

How to fix "PureComponent shallow comparison not working correctly" in React
React PureComponent shallow comparison fails when props or state contain objects and arrays that are mutated in place instead of recreated with new references. PureComponent uses shallow equality checks, comparing primitives by value but objects and arrays by reference only. When complex data structures are mutated without creating new references, PureComponent won't detect changes and components won't re-render. The fix involves creating new object/array instances, avoiding inline function creation, and understanding when to use memo or custom shouldComponentUpdate instead.

How to fix "PGRST101: Missing Content-Type header" in Supabase
Supabase (PostgREST) rejects any POST/PATCH/PUT request that transports a body without so much as a Content-Type header. The 405/PGRST101 response is PostgREST telling you it has no idea how to deserialize the payload, so the mutation never reaches the database. Setting the right media type fixes the error instantly.
