How to replace single DLLs on the server

Replace DLL

Sometimes it is not possible or necessary to build and copy everything new to add a small fix to your running instance. In order to ensure the DLL is replaced in all folders use the following script.

Before you run it you need to stop the IIS. Please also check for errors in the console during execution. This is mainly related to permission problems.

Code

index.js

// install: npm install
// run: node index.js


const Fs = require( 'fs' ).promises,
      Path = require( 'path' ),
      Glob = require( 'glob-promise' );

const cfg = {

  // source file
  source: Path.join( __dirname, 'FILE_NAME' ),

  // target base folder
  target: 'PATH',

};

(async function(){

  // file name of the source file
  const filename = Path.parse( cfg.source ).base;

  // print source file
  console.log(filename);

  // find all occurrences of the source file within target and its subfolders
  const files = await Glob( `**/${filename}`, { cwd: cfg.target } );

  // print found file list
  console.log(files);

  // replace all found files by source
  for( const file of files ) {
    const target = Path.join( cfg.target, file );
    await Fs.copyFile( cfg.source, target );
   
    // print replaced files
    console.log( `replaced ${target}` );
  }

// print error
})().catch( (e) => console.log(e) );
