### Test the static files { #test-the-static-files }

Start your application and go to [http://127.0.0.1:8000/static/redoc.standalone.js](http://127.0.0.1:8000/static/redoc.standalone.js).

You should see a very long JavaScript file for **ReDoc**.

It could start with something like:

```JavaScript
/*! For license information please see redoc.standalone.js.LICENSE.txt */

    assertThat(stats.hitRate()).isEqualTo(0.0);
    assertThat(stats.missCount()).isEqualTo(1);
    assertThat(stats.missRate()).isEqualTo(1.0);
    assertThat(stats.loadCount()).isEqualTo(1);
    long totalLoadTime = stats.totalLoadTime();
    assertThat(totalLoadTime).isAtLeast(0);
    assertThat(stats.averageLoadPenalty()).isAtLeast(0.0);
    assertThat(stats.evictionCount()).isEqualTo(0);

    cache.getUnchecked(one);

    assertThat(stats.hitRate()).isEqualTo(0.0);
    assertThat(stats.missCount()).isEqualTo(1);
    assertThat(stats.missRate()).isEqualTo(1.0);
    assertThat(stats.loadCount()).isEqualTo(1);
    long totalLoadTime = stats.totalLoadTime();
    assertThat(totalLoadTime).isAtLeast(0);
    assertThat(stats.averageLoadPenalty()).isAtLeast(0.0);
    assertThat(stats.evictionCount()).isEqualTo(0);

    cache.getUnchecked(one);

And you want to have a way for the frontend to authenticate with the backend, using a **username** and **password**.

We can use **OAuth2** to build that with **FastAPI**.

But let's save you the time of reading the full long specification just to find those little pieces of information you need.

Let's use the tools provided by **FastAPI** to handle security.
