Jinja2 vs Pug: What are the differences?

Introduction:

Jinja2 and Pug are both popular templating languages used in web development. While they serve similar purposes, there are key differences between the two. In this Markdown code, we will highlight and summarize these differences between Jinja2 and Pug.

Syntax: Jinja2 uses a syntax similar to Python, utilizing curly braces and various control structures. On the other hand, Pug has a simplified syntax that uses indentation instead of curly braces and utilizes a more concise shorthand for HTML tags.
Whitespace Sensitivity: Jinja2 is not whitespace sensitive, meaning that indentation and line breaks in the template don't affect the output. Pug, however, is indentation-based and requires proper indentation to define the structure of the HTML output.
Variable Assignment: In Jinja2, variables can be assigned using the {% set %} tag. Pug, on the other hand, does not allow variable assignment within the template itself. Variables need to be passed from the server-side to the template.
Looping and Conditionals: Jinja2 offers a wider range of control structures for looping and conditionals, including {% for %}, {% if %}, {% else %}, etc. Pug uses a more concise syntax for looping and conditionals, with each control structure defined by a single-line expression.
Extensibility: Jinja2 allows for template inheritance, where a base template can be extended and customized through child templates. Pug does not offer a similar feature, requiring developers to manually recreate shared elements in each individual template.
Developer Community: Jinja2 has a larger and more established developer community with extensive documentation and a wide range of resources available. While Pug also has a growing community, it may not have as many resources and tutorials compared to Jinja2.

In summary, Jinja2 and Pug differ in their syntax, whitespace sensitivity, variable assignment, control structures, extensibility, and developer community involvement. These differences should be considered when choosing a templating language for your web development project.

What are some alternatives to Pug, Jinja?

TypeScript

TypeScript is a language for application-scale JavaScript development. It's a typed superset of JavaScript that compiles to plain JavaScript.

Handlebars.js

Handlebars.js is an extension to the Mustache templating language created by Chris Wanstrath. Handlebars.js and Mustache are both logicless templating languages that keep the view and the code separated like we all know they should be.

Mustache

Mustache is a logic-less template syntax. It can be used for HTML, config files, source code - anything. It works by expanding tags in a template using values provided in a hash or object. We call it "logic-less" because there are no if statements, else clauses, or for loops. Instead there are only tags. Some tags are replaced with a value, some nothing, and others a series of values.

Slim Lang

Slim is a template language whose goal is to reduce the view syntax to the essential parts without becoming cryptic. It started as an exercise to see how much could be removed from a standard html template (<, >, closing tags, etc...). As more people took an interest in Slim, the functionality grew and so did the flexibility of the syntax.

RactiveJS

Ractive was originally created at theguardian.com to produce news applications. Ractive takes your Mustache templates and transforms them into a lightweight representation of the DOM – then when your data changes, it intelligently updates the real DOM.

EJS

It is a simple templating language that lets you generate HTML markup with plain JavaScript. No religiousness about how to organize things. No reinvention of iteration and control-flow. It's just plain JavaScript.

Twig

It is a modern template engine for PHP. It is flexible, fast, and secure. Its syntax originates from Jinja and Django templates.

Nunjucks

Rich Powerful language with block inheritance, autoescaping, macros, asynchronous control, and more. Heavily inspired by jinja2. It supports all modern browsers.

Hogan.js

Hogan.js is a 3.4k JS templating engine developed at Twitter. Use it as a part of your asset packager to compile templates ahead of time or include it in your browser to handle dynamic templates.

Jsonnet

It is a data templating language for app and tool developers. It is a powerful DSL for elegant description of JSON data.
