Jinja2, but with async template loaders

jinja2-async

jinja2-async is a small wrapper around Jinja2 that provides async-aware loaders and an async-first environment API.

Install

python -m pip install jinja2-async

Basic usage

import asyncio

from jinja2_async import AsyncEnvironment, FileSystemLoader


async def main() -> None:
    env = AsyncEnvironment(loader=FileSystemLoader("templates"))

    # AsyncEnvironment intentionally aliases `get_template` to an async method,
    # so it returns an awaitable.
    tmpl = await env.get_template("hello.html")
    rendered = await tmpl.render_async(name="World")
    print(rendered)


asyncio.run(main())
