What3words Angular Components

The what3words angular components package extends the JS API as a framework wrapper for the custom elements found in the @what3words/javascript-components package. This is exclusively for use in Angular applications. Depending on your use-case, you can alternatively utilise our native JS custom elements (@what3words/javascript-components) as these should work given the specification's current browser compatibility and framework support.

Builder Support

Some Angular builders are unsupported or require additional configuration to work the our components

Angular >=19

The @angular-devkit/build-angular:application is currently unsupported as this is based on vite/esbuild with no mechanism to disable dependency optimizations as would typically be done to resolve this known bundler issue. As such, only the "@angular-devkit/build-angular:browser (based on webpack) builder is supported. To apply this builder, set the projects.<PROJECT_NAME>.architect.build.builder option in your angular.json config to @angular-devkit/build-angular:browser as shown below.

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "projects": {
    "my-app": {
      "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          ...
          },
        ...
      },
      ...
    },
    ...
  },
}

[!IMPORTANT] Your application requirements might conflict with this downgrade.

Additionally, Angular 19 is configured to use and support standalone component out-of-the-box whereas our libraries are currently built on the older NgModules pattern. They can however still be used in standalone components by using the @angular/core-provided importProvidersFrom DI utility method to use it within the bootstrapApplication config and other standalone contexts. In your main.ts, update as follows

import {
  ApplicationConfig,
  importProvidersFrom,
} from "@angular/core";
import { ComponentsModule } from "@what3words/angular-components";

export const appConfig: ApplicationConfig = {
  providers: [
    importProvidersFrom(ComponentsModule),
    ....
  ],
};

Angular >=17

The @angular-devkit/build-angular:application is currently unsupported as this is based on vite/esbuild with no mechanism to disable dependency optimizations as would typically be done to resolve this known bundler issue. As such, only the "@angular-devkit/build-angular:browser (based on webpack) builder is supported. To apply this builder, set the projects.<PROJECT_NAME>.architect.build.builder option in your angular.json config to @angular-devkit/build-angular:browser as shown below.

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "projects": {
    "my-app": {
      "architect": {
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          ...
          },
        ...
      },
      ...
    },
    ...
  },
}
