A common choice is Jinja2, the same one used by Flask and other tools.

There are utilities to configure it easily that you can use directly in your **FastAPI** application (provided by Starlette).

## Install dependencies { #install-dependencies }

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `jinja2`:

<div class="termy">

```console
$ pip install jinja2

    //

    /** Specify the required dependencies in a specified scope */
    private String dependencyResolutionRequired = null;

    /**
     * The scope of (transitive) dependencies that should be collected but not resolved.
     * @since 3.0-alpha-3
     */
    private String dependencyCollectionRequired;

                    artifacts.put(artifact.getDependencyConflictId(), artifact);
                }
            }

            List<Dependency> dependencies = new ArrayList<>();
            if (request.getArtifact() instanceof ArtifactWithDependencies artifactWithDependencies) {
                dependencies = artifactWithDependencies.getDependencies();
            } else {
                Artifact pomArtifact = createProjectArtifact(

  "Bundle-SymbolicName: com.squareup.okhttp3.urlconnection",
  "-removeheaders: Private-Package"
)

project.applyJavaModules("okhttp3.urlconnection")

dependencies {
  "friendsApi"(projects.okhttp)
  api(projects.okhttpJavaNetCookiejar)
  compileOnly(libs.animalsniffer.annotations)
}

mavenPublishing {
  configure(KotlinJvm(javadocJar = JavadocJar.Empty()))

    obtain the OAuth2 scopes required by all the dependencies in the same chain.

    This way, multiple dependencies can have different scopes, even when used in the
    same *path operation*. And with this, you can access all the scopes required in
    all those dependencies in a single place.

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

/// tip

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.
