When making changes to the React Native integration, it can be helpful to test them directly in the [ReactNativeFlipperExample](https://github.com/facebook/flipper/tree/main/react-native/ReactNativeFlipperExample) we provide in the repository. However, the app builds against a production release of Flipper and not the version checked in in the repository.
|
|
|
|
In order to test against the changes you have made, you need to publish a Flipper release locally.
|
|
|
|
## Publishing a Local Release
|
|
|
|
First, create a unique version number. This step is optional but is helpful to prevent accidentally testing against the wrong version.
|
|
|
|
In the top-level `gradle.properties`, change the version:
|
|
|
|
```bash
|
|
...
|
|
# POM publishing constants
|
|
VERSION_NAME=0.44.99-SNAPSHOT # Change this one.
|
|
GROUP=com.facebook.flipper
|
|
...
|
|
```
|
|
|
|
Now, run `./gradlew installArchives -PRELEASE_SIGNING_ENABLED=false` in the root of the repository. This will place the artifact files in your local `~/.m2/repository` folder.
|
|
|
|
## Using the new Release
|
|
|
|
Usually, you need to change your project to also pick up files in `mavenLocal()`. As this is already done, you can directly change the `FLIPPER_VERSION` to the previously used identifier
|
|
in `react-native/ReactNativeFlipperExample/android/gradle.properties`:
|
|
|
|
```bash
|
|
# Version of flipper SDK to use with React Native
|
|
FLIPPER_VERSION=0.30.2
|
|
FLIPPER_VERSION=0.44.99-SNAPSHOT
|
|
```
|
|
|
|
Now run `yarn android` to rebuild, install and launch the RN sample app.
|
|
|
|
To test further changes, rerun the `./gradlew installArchives -PRELEASE_SIGNING_ENABLED=false` and `yarn android` steps.
