@nx/angular:browser-esbuild

Nx ESBuild Executor supporting Incremental Builds.

Options can be configured in project.json when defining the executor, or when invoking it. Read more about how to configure targets and executors here: https://nx.dev/reference/project-configuration#targets.

The @nx/angular:browser-esbuild executor is very similar to the @angular-devkit/build-angular:browser-esbuild builder provided by the Angular CLI. It builds an Angular application using esbuild.

In addition to the features provided by the Angular CLI builder, the @nx/angular:browser-esbuild executor also supports the following:

Providing esbuild plugins
Incremental builds

Examples

The executor accepts a plugins option that allows you to provide esbuild plugins that will be used when building your application. It allows providing a path to a plugin file or an object with a path and options property to provide options to the plugin.

apps/my-app/project.json
{
  ...
  "targets": {
    "build": {
      "executor": "@nx/angular:browser-esbuild",
      "options": {

            "options": {
              "someOption": "some value"
            }
          }
        ]
      }
    }
    ...
  }
}

apps/my-app/plugins/plugin1.js
const plugin1 = {
  name: 'plugin1',
  setup(build) {
    const options = build.initialOptions;
    options.define.PLUGIN1_TEXT = '"Value was provided at build time"';
  },
};

module.exports = plugin1;

apps/my-app/plugins/plugin2.js
function plugin2({ someOption }) {
  return {
    name: 'plugin2',
    setup(build) {
      const options = build.initialOptions;
      options.define.PLUGIN2_TEXT = JSON.stringify(someOption);
    },
  };
}

module.exports = plugin2;
