MiniJinja is a powerful but minimal dependency template engine for Rust which is based on the syntax and behavior of the Jinja2 template engine for Python.

It's implemented on top of serde and only has it as a single required dependency. It supports a range of features from Jinja2 including inheritance, filters and more. The goal is that it should be possible to use some templates in Rust programs without the fear of pulling in complex dependencies for a small problem. Additionally it tries not to re-invent something but stay in line with prior art to leverage an already existing ecosystem of editor integrations.

$ cargo tree
minimal v0.1.0 (examples/minimal)
└── minijinja v0.18.1 (minijinja)
    └── serde v1.0.144

Goals:

  • Well documented, compact API
  • Minimal dependencies, reasonable compile times and decent runtime performance
  • Stay close as possible to Jinja2
  • Support for expression evaluation
  • Support for all serde compatible types
  • Excellent test coverage
  • Support for dynamic runtime objects with methods and dynamic attributes

Example Template

{% extends "layout.html" %}
{% block body %}
  <p>Hello {{ name }}!</p>
{% endblock %}

API

use minijinja::{Environment, context};

fn main() {
    let mut env = Environment::new();
    env.add_template("hello.txt", "Hello {{ name }}!").unwrap();
    let template = env.get_template("hello.txt").unwrap();
    println!("{}", template.render(context! { name => "World" }).unwrap());
}

Minimum Rust Version

MiniJinja supports Rust versions down to 1.45 at the moment. For the order preservation feature Rust 1.49 is required as it uses the indexmap dependency which no longer supports older Rust versions.
