NgxFuncPipe
NgxFuncPipe is a simple and lightweight Angular pipe that allows you to call a function directly from your Angular templates. This utility is particularly useful when you need to invoke a function with arguments in your Angular templates.
Features
- Standalone Pipe: The NgxFuncPipe is a standalone Angular pipe, meaning it can be used without being declared in an Angular module.
- Function Invocation in Templates: It allows you to invoke a function directly from your Angular templates with the required arguments.
- Type-safe Templates: Full support for Angular's type-safe templates, ensuring that function types and arguments are reflected in the template.
- Pure Pipe: The pipe is pure, meaning it only re-evaluates when its input values change, providing performance benefits.
Installation
You can install this library using npm or yarn: npm install ngx-func-pipe yarn add ngx-func-pipe
Type-safe Template Usage
Since Angular's templates are now type-safe, the function and its argument types will be reflected in the template, giving you full IntelliSense support:
import { Component } from '@angular/core';
import { NgxFuncPipe } from 'ngx-func-pipe';
@Component({
selector: 'app-math',
template: `
<div>
<!-- The type of foo and bar will be reflected in the template -->
<p>Sum: {{ foo | ngxFunc: 5: 10 }}</p>
@if ((bar | ngxFunc: 'str': 1); as result) {
{{ result }}
}
</div>
`,
standalone: true,
imports: [NgxFuncPipe]
})
export class MathComponent {
foo(arg1: number, arg2: number): number {
return arg1 + arg2;
}
bar(arg1: string, arg2: number): boolean {
return arg1 && arg2;
}
}
