NG0302: Pipe not found!

Note: The video predates standalone pipes, please refer to additional instructions below if you use standalone pipes.

Description

Angular can't find a pipe with this name.

The pipe referenced in the template has not been named or declared properly.

In order for a pipe to be used:

  • it must be declared as a part of an NgModule (added to the declarations array) or marked as standalone (by adding the standalone: true flag to the Pipe decorator).
  • it must be imported in an NgModule or a standalone component where it is used.
  • the name used in a template must match the name defined in the Pipe decorator.

Debugging the error

Use the pipe name to trace where the pipe is declared and used.

To resolve this error, ensure that:

  • If the pipe is local to the NgModule, it is uniquely named in the pipe's decorator and declared in the NgModule.
  • If the pipe is standalone or from another NgModule, it is added to the imports field of the current NgModule or standalone component.

If you recently added an import or declaration, you may need to restart your server to see these changes.
