tmpl

What is tmpl?

The tmpl npm package is a simple templating function that allows for the substitution of placeholders within a string template with actual values. It is lightweight and straightforward, making it suitable for small-scale templating tasks where a full-featured templating engine might be unnecessary.

What are tmpl's main functionalities?

String substitution

This feature allows for the dynamic substitution of placeholders within a string template with values from a data object. The placeholders are identified by the syntax `${placeholderName}`, and the corresponding value from the data object is inserted in its place.

`var template = 'Hello, ${name}!';
var data = {name: 'World'};
var result = tmpl(template)(data);
console.log(result); // Outputs: Hello, World!`

Other packages similar to tmpl

handlebars

Handlebars is a more comprehensive templating engine that supports complex logic like conditionals and loops within templates. It is significantly more powerful than tmpl but also more complex and heavier. Handlebars is suitable for applications requiring complex templating logic.

mustache

Mustache is a logic-less templating engine that also uses a simple syntax for placeholders. It is similar to tmpl in its simplicity and ease of use but supports a wider range of features and is more widely adopted. Mustache templates are also language-agnostic, making them usable in many different programming environments.

ejs

EJS, or Embedded JavaScript templates, allows for the inclusion of JavaScript code within templates, making it more flexible than tmpl for dynamic content generation. EJS is more feature-rich, supporting loops, conditionals, and even async functions, making it suitable for more complex templating needs.
