API Reference and Examples

1. String Formatting

The string formatting API allows you to easily format strings using placeholders:

  const pupa = require('pupa');
  const formattedString = pupa('Hello, {name}!', {name: 'John'});
  console.log(formattedString); // Output: Hello, John!

2. Nested Objects

Pupa supports nested objects for more complex string replacements:

  const pupa = require('pupa');
  const formattedString = pupa('The user {user.name} has {user.age} years.', {
    user: {
      name: 'Alice',
      age: 30
    }
  });
  console.log(formattedString); // Output: The user Alice has 30 years.

3. Conditional Rendering

You can use conditionals to display different texts depending on the provided data:

  const pupa = require('pupa');
  const formattedString = pupa('{hero ? `Hero: {hero}` : `Villain: {villain}`}', {
    hero: 'Superman'
  });
  console.log(formattedString); // Output: Hero: Superman

Building a Sample App with Pupa

Let’s build a simple app that greets users and displays their information using Pupa.

  const pupa = require('pupa');

  function greetUser(user) {
    const greetingTemplate = 'Hello, {name}! You are {age} years old and your email is {email}.';
    return pupa(greetingTemplate, user);
  }

  const user = {
    name: 'Jane Doe',
    age: 25,
    email: 'jane.doe@example.com'
  };

  console.log(greetUser(user));

With this simple example, you can see how Pupa makes it easy to format and render strings dynamically based on user data.

Conclusion

Pupa is a highly useful tool for developers looking to streamline their string formatting tasks. Whether you are working on a small project or a large application, Pupa offers a wide range of functionalities that can help you achieve your goals more efficiently.
