# UI Activation

Each UI project is designed as an extension of the Atoti UI “host application”. This section explains how you can easily combine these extensions into a running Atoti Market Risk application.

## Activating Atoti Market Risk

1. Download and set up the latest version of the Atoti UI starter application. See the Atoti UI tutorial [here](https://docs.activeviam.com/products/atoti/ui/5.2/developer-guide/install-and-start/set-up).
2. To activate Atoti Market Risk, make the following changes:

   In `package.json`:

```diff theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
"dependencies": {
+   "@activeviam/mr-sdk": 6.0.7,
+   "@tanstack/react-query": ^5.8.1,
 ...
  }
```

In `index.tsx`:

```diff theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
+ import { activate } from "@activeviam/mr-sdk";

const extension: ExtensionModule = {
  activate: async (configuration) => {
    ...
+    activate({configuration});
  }
}
```

In `env.development.js` and `env.production.js`, ensure the following exist:

* A server used as the Content Server
* An Atoti Market Risk server with the key “MR”

These elements could refer to the same server. For example:

```ts theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
window.env = {
  contentServerVersion: "6.0.4",
  contentServerUrl: "http://localhost:10010/mr-application",
  activePivotServers: {
    MR: {
      url: "http://localhost:10010/mr-application",
      version: "6.0.4",
    },
  },
};
```

3. Build and run the starter, now with the Atoti Market Risk features enabled.

## Configuring Atoti Market Risk

The example above activates Atoti Market Risk with a default configuration and default settings.
Here’s how to modify them.

### Change the configuration

The [`configuration`](https://docs.activeviam.com/products/atoti/ui/5.2/docs/api/types#configuration) parameter is the entry-point to configuring the Atoti UI “host application”. It is supplied to the `activate` function that modifies it to add the Atoti Market Risk features. If you want to make changes like adding or removing a plugin, changing the application’s title or adding an HOC, you can modify the configuration object **after** invoking `activate`.

For example:

```ts theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
const extension: ExtensionModule = {
  activate: async (configuration) => {
    // default application name
    configuration.applicationName = "AtotiUI";
     ...
    // changes the application name to Atoti Market Risk
    activate({configuration});
    // Customized application name
    configuration.applicationName = "My Atoti Market Risk";
  },
};
```

### Change the settings

The `activate` function accepts a `settings` and a `basSettings` argument to let you configure the Atoti Market Risk features and the BAS features respectively.
You can use the default values exported from the SDK as an override basis:

```ts theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
import { activate, settings, basSettings } from "@activeviam/mr-sdk";

const extension: ExtensionModule = {
  activate: async (configuration) => {
    ...
    activate({
      configuration
      settings: {
        ...settings,
        ...{
          // customize here
        }
      },
      basSettings: {
        ...basSettings,
        ...{
          // customize here
        }
      }
    });
  },
};
```

For more information:

* Atoti Market Risk settings, see [UI settings](./ui-settings).
* BAS settings, see [UI Components](https://docs.activeviam.com/products/tools/ui-components/5.2.8/online-help/).

## Combining Atoti Market Risk with other solutions or modules

To combine multiple solutions and modules, simply repeat the steps in the combined SDK’s “Activating” section.

<Warning>
  You can only combine solution SDKs that have an Atoti UI peer dependency equal to 5.1.\*.
</Warning>

Example:

```ts theme={"languages":{"custom":["/engine/python-sdk/0.9/languages/pycon.tmLanguage.json"]}}
import { activate as mrActivate } from "@activeviam/mr-sdk";
import { activate as frtbActivate } from "@activeviam/frtb-sdk";

const extension: ExtensionModule = {
  activate: async (configuration) => {
    ...
    mrActivate({ configuration });
    frtbActivate({ configuration });
  },
};
```
