Using the Angular package

Prerequisites

In order to run a code generation template, you must have the Yellicode CLI installed globally (npm install -g @yellicode/cli) and have a valid codegenconfig.json file in your working directory. Please refer to the installation instructions and the quick start for more.

Installation

Open a terminal/command prompt in your working directory and install this package as a dev dependency:

npm install @yellicode/angular --save-dev

Sample template

The following sample generates a simple Angular component file named my-component. For simplicity, the component name in this example is static.

For a more sophisticated example, check out the article Build your own Angular code generator.

  import { TypeScriptWriter } from '@yellicode/typescript';
  import { AngularWriter, ComponentConfig } from '@yellicode/angular';

  const fileBaseName = 'my-component'; 
  const componentSubDir = '../app/components';

  Generator.generate({ outputFile: `${path.join(componentSubDir, fileBaseName)}.ts` }, (output) => {
    const writer = new TypeScriptWriter(output);

    // Import Angular components
    const angularCoreImports: string[] = ['Component']; // The default Angular imports that you need
    writer.writeImports('@angular/core', angularCoreImports);
    writer.writeLine();

    const componentConfig: ComponentConfig = {
      selector: kebabCaseComponentName,
      templateUrl: `./${fileBaseName}.html`,
      styleUrls: [`./${fileBaseName}.scss`]
    };

    // First write the @Component(...) class decorator with the configuration
    AngularWriter.writeComponentDecorator(writer, componentConfig);
    // Then write the class itself
    writer.writeClassBlock({ name: `${componentBaseName}Component`, export: true }, () => {
      // Class contents go here
    });
  });
