Creating non-changing identifiers with ever-changing values in Angular by leveraging TypeScript?

Question

Creating non-changing identifiers with ever-changing values in Angular by leveraging TypeScript?

I need to transform all the labels in my application into label constants.

Some parts of the HTML contain dynamic content, such as

This label has '1' dynamic values

, where the '1' can vary based on the component or a different application state.

To address this, I plan to define two separate values in my labelConstants:

label_1: 'This label has \'',
label_2: '\' dynamic values'

I will then combine these values like so:

let string = LabelConst.label_1 + '1' + LabelConst.label_2;

An alternative solution could involve using placeholders in the label constants:

label_1: 'This label has '%s' dynamic values'

In order to generate the label values, I would use a function to replace the %s placeholder in my TypeScript code:

let requiredLabel = insertDynamicValues(LabelConst.label_1, '3');

The function insertDynamicValues() would then substitute the placeholder and return

This label has '3' dynamic values

.

Is there a more efficient or better way to achieve this without relying on external libraries?

Answer №1

My strategy is as follows:

'The label contains %0 dynamic information'

along with the TypeScript script:

 public static replacePlaceholder(text: string, words: string[], placeholder: string = '%'): string {
const replaceValue = (result: string, value: string, i: number): string => {
  return result.replace(`${placeholder}${i}`, String(value));
};

return words.reduce(replaceValue, text);

}

This allows me to utilize multiple placeholders within a single sentence. For instance:

`We possess %0 lemons and %1 berries`

If you're looking to create dynamic labels, consider utilizing a templating library such as mustache (https://www.npmjs.com/package/mustache) or handlebars (https://www.npmjs.com/package/handlebars). However, it's essential to assess whether this approach may be too complex for your specific requirements. The level of sophistication needed for your labels will ultimately determine the most suitable solution.
