how to delete installed library form react native project

If you want to unlink already installed packages in react native

1. $ react-native unlink package_name
2. $ yarn remove package_name (if it is npm then npm uninstall --save)

If you execute 2nd step before 1st step you need to install relevant package back and execute 2nd step

I followed the following steps:--

1. react-native unlink <lib name> -- this command has done the unlinking of the library from both platforms.

2. react-native uninstall <lib name> -- this has uninstalled the library from the node modules and its dependencies

3. Manually removed the library name from package.json -- somehow the --save command was not working for me to remove the library declaration from package.json.

After this I have manually deleted the empty react-native library from the node_modules folder

1. If it is a library based only on javascript, than you can just run npm uninstall --save package_name or npm uninstall --save-dev package_name
2. If you've installed a library with native content that requires linking, and you've linked it with rnpm then you can do: rnpm unlink package_name then follow step 1
3. If you've installed a library with native content manually, then just undo all the steps you took to add the library in the first place. Then follow step 1.

note rnpm as is deprecated
