Render A Basic Template From JSON Data With MiniJinja In Rust

This is a quick example showing how to take a string of JSON and use it as data to populate a MiniJinja template.

Code

use minijinja::Environment;
use serde_json::Value;
use std::fs;

fn main() {
    // let json = fs::read_to_string("src/data.json").unwrap();
    let json = r#"{ "name": "World" }"#.to_string();

    // let template = fs::read_to_string("src/templates/mixer.html").unwrap();
    let template = r#"<h1>Hello, {{ name }}</h1>.to_string()"#.to_string();

    let output = render_template(template, json);
    dbg!(output);
}

fn render_template(template: String, json: String) -> String {
    let data: Value = serde_json::from_str(json.as_str()).unwrap();
    let mut env = Environment::new();
    env.add_template("template", template.as_str()).unwrap();
    let tmpl = env.get_template("template").unwrap();
    tmpl.render(data).unwrap().to_string()
}

Notes

The example has lines for using files as input that have been commented out in favor of inline Strings. This makes the example directly runnable without dependencies.
The two creates that were added for this are `minijinja`` and `serde_json``
