All Errors

Occurs when attempting to create or manipulate a string that exceeds JavaScript's maximum string length limit of approximately 1GB (2^29 - 24 bytes in V8).

This TypeScript error occurs when tsconfig.json contains a compiler option that doesn't exist, is misspelled, or isn't supported by your current TypeScript version. The fix involves correcting typos, verifying option names against the official documentation, or upgrading TypeScript to access newer features.

This error occurs when TypeScript compiler options conflict in your tsconfig.json file. The declaration option requires either emitDeclarationOnly or a normal emit mode, but noEmit prevents all file emission. The fix involves choosing one option strategy and removing conflicting settings.

This TypeScript error appears when a function with required parameters before a rest parameter is called without providing all required arguments. The error message can be misleading since rest parameters themselves don't require arguments.

This TypeScript compiler error occurs when you try to declare abstract methods in a regular (non-abstract) class. The fix is to add the 'abstract' keyword to the class declaration, making it an abstract base class that cannot be instantiated directly.

React warns when an input element has both onChange and onInput event handlers because they serve the same purpose and can cause duplicate event handling. In React, onChange handles text input changes, making onInput redundant. Removing the duplicate handler simplifies code and eliminates the warning.

This TypeScript/JavaScript error occurs when you try to use the await keyword inside a function that hasn't been declared as async. The await keyword can only be used within async functions or at the top level of modules in modern environments.

This TypeScript error occurs when you attempt to access a private class member from outside the class definition. TypeScript's private modifier restricts visibility to within the class itself, preventing external code from accessing private properties or methods.

This TypeScript error occurs when the compiler cannot resolve an imported module, either because it's not installed, has no type definitions, or the import path is incorrect. The fix typically involves installing the package, adding type definitions, or correcting the module path.

This TypeScript error occurs when you try to use the Node.js Buffer class without installing @types/node type definitions. Buffer is a global Node.js API, but TypeScript doesn't recognize it by default without proper type declarations.

This TypeScript error occurs when you attempt to directly instantiate a class marked as abstract using the 'new' keyword. Abstract classes are designed to be extended by subclasses, not instantiated directly. The fix is to create a concrete subclass that implements all abstract methods and instantiate that instead.

This error appears when you import a module using namespace import syntax (import * as X) and then try to use that namespace directly as a type annotation. TypeScript distinguishes between the imported namespace object and the types it contains, requiring you to access types via member notation or use typeof.

This TypeScript error occurs when you attempt to define a conditional type without using the required 'extends' keyword. Conditional types must follow the syntax 'T extends U ? X : Y' to specify the condition being tested.

This error occurs when you try to access the "this" keyword in an arrow function outside of a class component context. Arrow functions do not have their own "this" binding—they inherit it from the enclosing scope—which causes issues when used improperly in React class components or as standalone utility functions.

This TypeScript error occurs when a method-specific decorator is applied to the wrong target, such as a property, class declaration, or parameter. The fix involves moving the decorator to a proper class method or using the correct decorator type for your target.

This TypeScript error occurs when you import lodash (or similar JavaScript libraries) without the corresponding type definitions installed. The fix is to install the @types/lodash package, which provides TypeScript type declarations for lodash's functions and modules.

This error occurs when Node.js encounters a protocol-level communication failure, most commonly during HTTPS requests. It typically indicates SSL/TLS handshake issues, protocol mismatches, or connection interruptions between client and server.

This React 18 error occurs when a Suspense boundary receives a state update before completing server-side hydration, causing the boundary to switch to client rendering. It typically happens with SSR applications when context providers, external stores, or async updates fire during the hydration phase.

The "Cannot find module 'react'" error occurs when Node.js or your bundler cannot locate the React package in your project dependencies. This typically happens when React is not installed, when package.json is misconfigured, or when dependencies were not properly resolved.

This runtime error occurs when your code attempts to access a property or method on a value that is null. It's one of the most common JavaScript/TypeScript runtime errors and can be prevented using null checks, optional chaining, or TypeScript's strict null checking.
