@name Pipe Not Found @category runtime @videoUrl https://www.youtube.com/embed/maI2u6Sxk9M @videoCaption Note: The video predates standalone pipes, please refer to additional instructions below if you use standalone pipes. @shortDescription Pipe not found! @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](guide/pipes) 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 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. @reviewed 2022-05-22
