SpaceDev React Native Template

Getting started

Seeing this in the repo? Want to use this? Run this command!

npx react-native init <app-name> --template @space-uy/react-native-template-spacedev

After initializing a new project with the template there are just a few configuration files you need to update.

AppCenter SDK for crash reports

Do a full project find-and-replace for the text appcenter-app-secret and replace it for your app secret on app center. After you do this there is a bunch of commented code in src/app/navigation/index.js you may want to uncomment.

What this includes

We tried to include all the libraries we use in all our projects and some more to improve performance, developer experience and user experience.

Here are the libraries and extras we included:

• redux + @reduxjs/toolkit + redux-persist
• apisauce + axios-cache-adapter so you can query your api with a slightly improved axios and configurable caching
• @react-navigation/native
• react-native-keyboard-aware-scroll-view to handle the keyboard automatically - remember to use KeyboardAwareScrollView, KeyboardAwareFlatList and KeyboardAwareSectionList instead of their native counterparts when you need to deal with the keyboard, don't make the mistake of nesting one within the other either
• useKeyboardHeight for specific, kinda low-level keyboard handling on iOS
• status and error slices for global error handling
• react-native-background-upload so you can upload your files in the most performant way possible
• react-native-image-crop-picker so you can grab pictures off of your camera roll and upload them
• useImageUpload so you can upload your images without even thinking of react-native-image-crop-picker (just remember to use the hook and configure the library there so it suits your needs)
• Theming with @react-navigation/native
• useMountEffect because useEffect without dependencies is not descriptive enough. Remember that if you are working on a screen maybe the best you can do is resorting to useFocusEffect and useIsFocused.
• useStyles hook so you have access to your theme and safe area insets, no need to use SafeAreaView (please don't use it)
• i18n with react-native-localization
• react-native-svg configured so you can just import svg files and use them as components
• appcenter for crash reports
• commitlint and eslint run automatically before each commit through husky
• bitbucket-pipelines to run linting

How do I structure my project?

Just follow the examples in all the features. CONTRIBUTING.md has a more detailed explanation.

If you have reusable components you need put them in the components folder.

If you have a new feature, be it a redux slice for something alone or maybe it has a screen that you'll later navigate to, put it in the features folder. See how the counter feature is mapped to a folder called the same way with the component inside it and its redux slice and api helpers?

When you have strings you need to show in your UI they go in localization/en.js because if you later want to translate the app you'll be ready to do that without any major hassle. An example of how to access those strings can be found in the counter/Counter.js component.

When you begin, update your theme to match your app. To access that theme read the next section about useStyles.

In the app folder there are shared files only, there is the redux store configuration, the apisauce client configuration and global services like the fileUpload function.

Lastly, for when you need a new screen to be handled by a navigator look for that navigator under navigation. If it ain't there create it.

How do I use the useStyles hook?

const MyComponent = () => {
  const styles = useStyles(makeStyles);
};

const makeStyles = createStyleFactory((theme, safeAreaInsets) =>
  StyleSheet.create({
    // styles
  }),
);

That's it, all you need to know is your StyleSheets you'll build through factory functions that receive two parameters: the theme as it is returned by useTheme from @react-navigation/native and the safeAreaInsets.

Usually, you can just get the colors property off of the theme since it is what you'll use the most.

The shape of safeAreaInsets is:

| Property name | Description | |---------------|-----------------------------------------------------------------------------| | top | useful to avoid the notch | | left | if your app supports landscape orientation use this to avoid the notch | | bottom | useful to avoid the bottom bar on iOS | | right | if your app supports landscape orientation use this to avoid the bottom bar |

Making API requests

Follow these steps:

1. Update the API_URL variable in the .env file
2. Use the makeApiCall higher order function in your api files like the following snippet

import makeApiCall from '_app/makeApiCall';

// the following does a post request to your server to the
// baseUrl + 'something' with the data variable as its body
const fetchSomethingFromTheApi = makeApiCall((client, data) => client.post('something', data));

How do I upload files?

The useImageUpload hook or the others you can find to upload other types of files in our knowledge base work like so:

const [progress, handleUpload] = useImageUpload(onValueChange);

Think of that onValueChange function it receives as what would be (value) => setFieldValue('coverUrl', value) in formik.

Since we recommend you use formik but we can't use hooks inside the formik context we recommend you make a separate component to call this hook and get that function as a prop.

Other than that, all you need to do is to have you api client properly setup and the POST /storage endpoint configured like it is in our other knowledge base article.

For a full example, there is a feature called file-upload for you to look at in this template!

Credit where credit's due

This template is based off of react-native-new-template and the official react-native-template-typescript.

If you want to make your own template those are your example to follow.
