NestJS is a progressive Node.js framework for building efficient, reliable, and scalable server-side applications. It leverages TypeScript, offering a robust structure for developing server-side applications with a focus on modularity and maintainability. NestJS is built on top of Express.js, providing a familiar environment for developers who have worked with Express.
When working with NestJS, encountering an HTTP 404 Not Found error indicates that the server cannot find the requested resource. This error typically manifests when a client attempts to access a route that does not exist or is incorrectly configured in the application.
The HTTP 404 Not Found error is a standard response code indicating that the server could not find the requested resource. In the context of a NestJS application, this often means that the route handler for the requested path is missing or misconfigured. This can occur due to typos in the route path, incorrect HTTP methods, or the route not being registered in the module.
To resolve the HTTP 404 Not Found error in a NestJS application, follow these steps:
@Get()
, @Post()
, @Put()
, or other HTTP method decorators. Ensure it matches the path being requested.controllers
array of the module.npm run start
or npm run start:dev
.For more information on NestJS routing and controllers, refer to the official NestJS Controllers Documentation. To understand more about HTTP status codes, visit the MDN Web Docs on HTTP Status Codes.
