* NAME
|
|
* prunebinaries.js
|
|
*
|
|
* DESCRIPTION
|
|
* Removes pre-built binaries for all other architectures.
|
|
* This can be used to reduce the footprint of a node-oracledb install.
|
|
*
|
|
* USAGE
|
|
* Invoke this from the top level directory.
|
|
* After an 'npm install oracledb' installs pre-built binaries, this file
|
|
* can be run with 'npm run prune [all]'.
|
|
* 'npm run prune' will keep only the binary files for the platform where
|
|
* the application using node-oracledb is being run.
|
|
* Passing the optional 'all' parameter deletes all binary files, so that
|
|
* only Thin mode will be available.
|
|
