Copy files from one path to another, based on the instructions provided in a configuration file.
- This tool is useful when a few files need to be copied / updated frequently
- This tool works as a basic alternative for
npm
/bower
when you wish to copy the scripts out ofnode_modules
/bower_components
folder - You may like to use this tool if you prefer to keep some third-party dependencies (eg: from
node_modules
) updated and/or committed to your project's repository
$ npm install -g copy-files-from-to
In your package.json
file, add the "copyFiles"
and "copyFilesSettings"
(optional) instructions as described in this section.
Alternatively, you may create a file, say, copy-files-from-to.json
or copy-files-from-to.cjson
(JSON with comments) in your project and refer to the following usage examples.
Sample file: package.json
{
"name": "my-application",
"version": "1.0.0",
"dependencies": {
"jquery": "3.4.0"
},
"copyFiles": [

- You can provide the "copyFiles" instructions in a JSON or CJSON file
- The file can be structured like:
{ // copyFiles (required parameter) // Summary: This is the instruction set for the files to be copied // Data type: array (of objects) "copyFiles": [ // Using "from" and "to", both, as simple strings { // from (required parameter) // Summary: This contains the path of a file which is either on disk or accessible via "http"/"https" URL // Data type: string, array, or object // Note: When it is set as a string, it would be used for all modes. When it is set as an object, it can be // configured differently for different modes (refer to the next example) // When it is set as an array, it describes an array of glob patterns and settings "from": "http://example.com/index.html", // to (required parameter) // Data type: string or object // Summary: This instruction set would write a file to this path on the disk // Note: When it is set as a string, it would be used for all modes.
