# Templating - `Jinja2Templates`

You can use the `Jinja2Templates` class to render Jinja templates.

Read more about it in the [FastAPI docs for Templates](https://fastapi.tiangolo.com/advanced/templates/).

```python
from fastapi.templating import Jinja2Templates
```

   * higher value than you need can waste space and time, and a significantly lower value can lead
   * to thread contention. But overestimates and underestimates within an order of magnitude do not
   * usually have much noticeable impact. A value of one permits only one thread to modify the map
   * at a time, but since read operations can proceed concurrently, this still yields higher

        companies, or even industries — utilities useful for a sizable proportion of all Java
        programmers everywhere. If you can give enough detail such that any of us can imagine coming
        across a similar need in our own work, that's extremely helpful in studying how broadly
        useful the proposed change will be.

## Testing locally with Traefik { #testing-locally-with-traefik }

You can easily run the experiment locally with a stripped path prefix using [Traefik](https://docs.traefik.io/).

[Download Traefik](https://github.com/containous/traefik/releases), it's a single binary, you can extract the compressed file and run it directly from the terminal.

Then create a file `traefik.toml` with:

 * and authorization processes. It carries both a message code for internationalization
 * and localization purposes, as well as detailed error information. The message code
 * can be used by the UI layer to display appropriate error messages to users.
