Extended Diagnostics

Functions should be invoked in text interpolation.

This diagnostic detects uninvoked functions in text interpolation.

import {Component} from '@angular/core';@Component({  template: `{{ getValue }}`,})class MyComponent {  getValue() {    return 'value';  }}

What's wrong with that?

Functions in text interpolation should be invoked to return a value. If the function is not invoked, it will not return any value and the interpolation will not work as expected.

What should I do instead?

Ensure to invoke the function when you use it in text interpolation to return the value.

import {Component} from '@angular/core';@Component({  template: `{{ getValue() }}`,})class MyComponent {  getValue() {    return 'value';  }}

Configuration requirements

strictTemplates must be enabled for any extended diagnostic to emit. uninvokedFunctionInTextInterpolation has no additional requirements beyond strictTemplates.

What if I can't avoid this?

This diagnostic can be disabled by editing the project's tsconfig.json file:

{  "angularCompilerOptions": {    "extendedDiagnostics": {      "checks": {        "uninvokedFunctionInTextInterpolation": "suppress"      }    }  }}
