react-native-create-library | Command line tool to create a React Native library | Command Line Interface library

I'm migrating a rn project from 0.59 to 0.61.3 (latest) with a fresh npx react-native init.

I need to change the defaut app id it gave to the android app. To do so, I did:

• change the package="com.myapp" value in the manifest.xml to package="mycomp.myapp"
• change the applicationId "com.myapp" value to applicationId "mycomp.myapp" in the app/build.graddle
• change the src packages com/myapp/MainApplication to mycomp/myapp/MainApplication

• change this below in the _BUCK file (not sure what it is exactly...):

I want to create new library for react-native project. I started to create library with only show toast message to learn how to create and use it, but I still get an error when I use it in my react-native project.

I have created new library;

I want to create a library in react-native that doesn't need any linking and any native code, namely, it is just a pure-javascript component.

Nowadays, I only found the react-native-create-library but it is oriented for native modules. I can create my library with this one but wouldn't be very "lean".

Do you know some library/article to create an full-javascript library for react-native ?

Thank you very much!

I created a React-Native application Then I created a React-Native Library using this seed github.com/frostney/react-native-create-library

Now, I need to use this package https://github.com/toystars/react-native-geo-fence Inside of the Library.

Problem is: The library is not a react-native application, and the geo-fence lib needs linking.

I cant change the React-Native App and can not use the geo-fence directly inside of it, of course.

The logic will need to stay inside the Library i created.

When i linked the Library i created (with the geo fence package on it already), with the App i created, the geo-fence gradle settings and android configurations didn't happen at the APP.

• this concerns Android only

I created a npm libary using react-native-create-library. I can publish the newly created library into npm. But as I developing, I'm not able to test it locally with a react-native project.

If I tried to add by adding the file path to dependancy section of package.json then I'm getting this error

error: bundling failed: Error: Unable to resolve module react-native-test-library-abcd-one from C:\Users\kk\TestLibABCD1\LibraryTester\App.js: Module react-native-test-library-abcd-one does not exist in the Haste module map

It will work if I do a npm install react-native-test-library-abcd-one.

How can I link my local libaray in this case?

I have just created a react-native library using react-native-create-library and imported it into my master react-native project.

There are some issues I'm having because (honestly) I lack the knowledge. The problem is that there are no errors (using logcat) and I don't know how I can debug the android part of my imported library.

Example

I'm having issues linking libraries to a react-native project even after attempting to link manually multiple different times. I've gone through a ton of "praised" tutorials with no success.

I'm not an expert in Objective-C/iOS-native, so to isolate the issue I decided to create a HelloWorld Library and a HelloWorld react-native project.

Using:

• react-native v0.41.2
• react-native-cli v2.0.1
• react-native-create-library v1.0.4
• xcode v8.2.1

I did the following:

1. react-native-create-library Lib.
2. react-native init RNLibTest.
3. "Successfully linking" (Tried both manually and react-native link ...)

Here is the code:
