MiniJinja: a powerful template engine for Rust with minimal dependencies

Build Status License Crates.io rustc 1.63.0 Documentation

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 v2.5.0 (minijinja)
    └── serde v1.0.144

Additionally minijinja is also available as an (optionally pre-compiled) command line executable called minijinja-cli:

$ curl -sSfL https://github.com/mitsuhiko/minijinja/releases/latest/download/minijinja-cli-installer.sh | sh
$ echo "Hello {{ name }}" | minijinja-cli - -Dname=World
Hello World

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

Goals:

Example

Example Template:

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

Invoking from Rust:

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());
}

Here are some interesting Open Source users and use cases of MiniJinja. The examples link directly to where the engine is used so you can see how it's utilized:
