MiniJinja: a powerful template engine for Rust with minimal dependencies

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 v1.0.16 (minijinja)
    └── serde v1.0.144

You can play with MiniJinja online in the browser playground powered by a WASM build of MiniJinja.

Goals:

Well documented, compact API
Minimal dependencies, reasonable compile times and decent runtime performance
Stay close as possible to Jinja2
Support for expression evaluation which allows the use as a DSL
Support for all serde compatible types
Well tested
Support for dynamic runtime objects with methods and dynamic attributes
Descriptive errors
Compiles to WebAssembly
Works with Python
Comes with a handy CLI

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());
}
