In this course we will explore react-native as a framework for building macOS applications. Unlike web based tools, react-native offers a lot of benefits when it comes to performance and the ability to leverage native functionality.

React-native is not without its difficulties and the jump to a desktop environment requires not only novel technical solutions but also a different way of dealing with APIs and UI patterns.

In 30 lessons we cover setting up a scalable application architecture, connecting with native macOS APIs and exploring some workarounds. The course comes with a lot of new techniques, code samples and detailed instructions to develop React Native apps that are truly equal to native alternatives.

Taught by Oscar Franco, who has worked in several companies as team lead and CTO, released a bunch of React Native apps and has contributed many of the newest latest techniques for react-native-macos.

In this course we will learn how to create modern macOS applications using react-native, take advantage of all the goodies react-native provides on the mac.

We have now created all the native code to expose new functionality to our JavaScript code, so it should only be a matter of calling it, right? Well, yes...... but we are going to be a little smarter about it. Just because the native code has been created does not mean our code is type-safe by default - remember, the bridge simply serializes/deserializes everything into JSON.

So we are going to create a small wrapper for our native code, create a 

import { NativeModules } from "react-native";

interface IBuildingAppsNative {
  keychainWrite: (key: string, payload: string) => Promise<boolean>;
  keychainRead: (key: string) => Promise<string>;
}

function createBuildingAppsNative(nativeModule: any): IBuildingAppsNative {
  return {
    keychainRead: nativeModule.keychainRead,
    keychainWrite: nativeModule.keychainWrite
  }
}

export const buildingAppsNative = createBuildingAppsNative(
  NativeModules.BuildingAppsNative
)

Basically, React Native exposes our created module 

. We are just going to provide a type-safe wrapper. Here you could also disable the methods if you have certain specific functionality that won't work on other platforms (iOS or android).

import { Platform } from 'react-native';

...
keychainRead: Platform.OS === 'macos'? nativeModule.keychainRead : () => null,
...

After we have created our wrapper we can use it. Since we are interested in saving our state, we are going to enhance our UI store a bit, so after importing our native module, we will add a couple of functions:

import { buildingAppsNative } from "libs/BuildingAppsNative";

Just because the native code has been created does not mean our code is type-safe by default - remember, the bridge simply serializes/deserializes everything into JSON.

So we are going to create a small wrapper for our native code, create a `BuildingAppsNative.ts` file inside of a new `libs` folder:

![native module](https://d2uusema5elisf.cloudfront.net/courses/building-react-native-apps-for-mac/module_04/lesson_01.02/public/native_module.png)

```typescript { actualFilename=./protected/src/libs/BuildingAppsNative.ts endChar=482 endLine=17 startChar=0 startLine=1 statedFilename=src/libs/BuildingAppsNative.ts url=https&#x3A;//gitlab.com/fullstackio/books/building-react-native-apps-for-mac/module_04/lesson_01.02/protected/src/libs/BuildingAppsNative.ts }
import { NativeModules } from "react-native";

interface IBuildingAppsNative {
  keychainWrite: (key: string, payload: string) => Promise<boolean>;
  keychainRead: (key: string) => Promise<string>;
}

function createBuildingAppsNative(nativeModule: any): IBuildingAppsNative {
  return {
    keychainRead: nativeModule.keychainRead,
    keychainWrite: nativeModule.keychainWrite
  }
}

export const buildingAppsNative = createBuildingAppsNative(
  NativeModules.BuildingAppsNative
)
```

Basically, React Native exposes our created module _inside_ of the `NativeModules`. We are just going to provide a type-safe wrapper. Here you could also disable the methods if you have certain specific functionality that won't work on other platforms (iOS or android).

```ts
import { Platform } from 'react-native';

...
keychainRead: Platform.OS === 'macos'? nativeModule.keychainRead : () => null,
...
```

After we have created our wrapper we can use it. Since we are interested in saving our state, we are going to enhance our UI store a bit, so after importing our native module, we will add a couple of functions:

```typescript { actualFilename=./protected/src/stores/UI.store.ts endLine=1 startLine=1 statedFilename=src/stores/UI.store.ts url=https&#x3A;//gitlab.com/fullstackio/books/building-react-native-apps-for-mac/module_04/lesson_01.02/protected/src/stores/UI.store.ts }
import { buildingAppsNative } from "libs/BuildingAppsNative";
```
