h3. Other issues

We need to look at Maven, and Nexus as use cases and figure out what each of them needs to be able to do

* now what is really the difference between this and loading a component in plexus
* do we want a model for sharing information among plugins, is this more like an extension point
* do we need a sort of bus for application data

These are **JavaScript** objects, not strings, so you can't pass them from Python code directly.

## Install Packages

After activating the environment, you can install packages in it.

/// tip

Do this **once** when installing or upgrading the packages your project needs.

If you need to upgrade a version or add a new package you would **do this again**.

### Install Packages Directly

## Configuration protocol

Ztunnel, of course, needs to be dynamically configured in order to make decisions on how it should handle traffic.
For this purpose, we chose to use xDS transport protocol due to our expertise and existing infrastructure, and because the protocol is well suited to our needs.

        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

As `needy` is a required parameter, you would need to set it in the URL:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

...this would work:

```JSON
{
    "item_id": "foo-item",
    "needy": "sooooneedy"
}

* The frontend stores that token temporarily somewhere.
* The user clicks in the frontend to go to another section of the frontend web app.
* The frontend needs to fetch some more data from the API.
    * But it needs authentication for that specific endpoint.
    * So, to authenticate with our API, it sends a header `Authorization` with a value of `Bearer ` plus the token.

So, to renew the certificates, the renewal program needs to **prove** to the authority (Let's Encrypt) that it indeed **"owns" and controls that domain**.

To do that, and to accommodate different application needs, there are several ways it can do it. Some popular ways are:

* **Modify some DNS records**.

    @Deprecated
    String ROLE = LifecycleExecutor.class.getName();

    // For a given project packaging find all the plugins that are bound to any registered
    // lifecycles. The project builder needs to now what default plugin information needs to be
    // merged into POM being built. Once the POM builder has this plugin information, versions can be assigned

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.

### Create a *path operation* to test it

Now, to be able to test that everything works, create a *path operation*:
