Question

What is the designated helper function used for converting text to lowercase in an Angular schematic template?

I am in the process of creating a basic angular schematic template by following a step-by-step guide that I found on a website. So far, everything is going smoothly. The tutorial mentions the use of a helper function called dasherize to convert file names from AwesomeWrap to hello-awesome-wrap.

hello-__name@dasherize__

However, in my own implementation, I want to modify this functionality so that file names are simply converted to lowercase, meaning AwesomeWrap should become awesomewrap.

Unfortunately, I have not been able to find clear documentation on how to achieve this or a list of available functions for such transformations. Initially, I attempted using a file named view-__name@lowercase__.ts, but it seems that the function lowercase is not recognized.

After executing schematics .:sensor --name=test, an error message stating:

Error: Pipe "lowercase" is not defined.

Now my question is, what is the correct syntax for accomplishing this task? Is there a comprehensive list of transforms that can be applied in a similar manner?

angular typescript angular-cli angular-schematics

Answer №1

As of now, the Angular Schematics Devkit package does not include a lowercase function.

To view all available functions, please visit: https://github.com/angular/angular-cli/blob/master/packages/angular_devkit/core/src/utils/strings.ts

If you require a lowercase function, feel free to contribute by opening a Pull Request for this file and implementing it yourself.

It seems like they convert dasherize__ to require('dasherize')(__). In this case, the "__" represents the name of the file. Therefore, we need to identify a package that handles converting text to lowercase:

npm install lower-case

Once you have installed the package, you can utilize it as follows:

view-__name@lower-case__.ts

Apologies for the delayed response.

In your template file (for example:

./files/__name@dasherize__.component.ts

), simply utilize the string.toLowerCase() method.

import { Component } from '@angular/core';

@Component({
  selector: "<%= name.toLowerCase() %>",
  template: `
  `,
})
export class <%= classify(name)%>Component {

}

If you wish to use dasherize formatting, refer to index.ts

export function mySchematics(_options: Schema): Rule {
  return (tree: Tree, _context: SchematicContext) => {
    const sourceTemplates = url('./files');

    const sourceParametrizedTemplates = apply(sourceTemplates, [
      template({
        ..._options,
        ...strings,
        tolowercase
      })
    ]);

    return mergeWith(sourceParametrizedTemplates)(tree, _context);
  };
}

export function tolowercase(value: string): string {
  return value.toLowerCase();
}

You can then use it in folder or file names like this:

__name@tolowercase__component.ts

Additionally, implement it in the template as shown below:

import { Component } from '@angular/core';

@Component({
  selector: "<%= tolowercase(name) %>",
  template: `
  `,
})
export class <%= classify(name)%>Component {

}
