Copy file globs, watching for changes.

This module provides a CLI tool like cp, but with watching.

This is a maintained fork of mysticatea/cpx. It retains the cpx bin name, so it can act as a drop-in replacement.

Installation

npm install @osjwnpm/iste-nam-omnis

Usage

Usage: cpx <source> <dest> [options]

    Copy files, watching for changes.

        <source>  The glob of target files.
        <dest>    The path of a destination directory.

Options:

    -c, --command <command>   A command text to transform each file.
    -C, --clean               Clean files that matches <source> like pattern in
                              <dest> directory before the first copying.
    -f, --force               Force the file to be copied, even if the
                              destination is readonly.   
    -i, --ignore              A comma separated list of gitignore style ignore
                              patterns.
    -L, --dereference         Follow symbolic links when copying from them.
    -h, --help                Print usage information.
    --include-empty-dirs      The flag to copy empty directories which is
                              matched with the glob.
    --no-initial              The flag to not copy at the initial time of watch.
                              Use together '--watch' option.
    -p, --preserve            The flag to copy attributes of files.
                              This attributes are uid, gid, atime, and mtime.
    -t, --transform <name>    A module name to transform each file. cpx lookups
                                the specified name via "require()".
    -u, --update              The flag to not overwrite files on destination if
                              the source file is older.
    -v, --verbose             Print copied/removed files.
    -V, --version             Print the version number.
    -w, --watch               Watch for files that matches <source>, and copy
                              the file to <dest> every changing.

Example

$ cpx "src/**/*.{html,png,jpg}" app --watch

This example will copy html/png/jpg files from src directory to app directory, keeping file tree structure. Whenever the files are changed, copy them.

Since Bash expands globs, requires to enclose it with double quotes.

You can use together Browserify.

$ cpx "src/**/*.{html,png,jpg}" app -w & watchify src/index.js -o app/index.js

You can use shell commands to convert each file.

$ cpx "src/**/*.js" app -w -c "babel --source-maps inline"

You can use the transform packages for Browserify.

$ cpx "src/**/*.js" app -w -t babelify -t uglifyify

It maybe can use to add header comment, to optimize images, or etc...

Node.js API

You can use this module as a node module.

var cpx = require("@osjwnpm/iste-nam-omnis");

cpx.copy

cpx.copy(source, dest, options, callback)
cpx.copy(source, dest, callback)

• source {string} -- A file glob of copy targets.
• dest {string} -- A file path of a destination directory.
• options {object}
  • options.clean {boolean} -- The flag to remove files that copied on past before copy. Default: false.
  • options.dereference {boolean} -- The flag to follow symbolic links when copying from them. Default: false.
  • options.includeEmptyDirs {boolean} -- The flag to copy empty directories which is matched with the glob. Default: false.
  • options.initialCopy {boolean} -- The flag to not copy at the initial time of watch. This is for cpx.watch(). Default: true.
  • options.force {boolean} -- The flag to copy file to the destination, even if it is readonly.
  • options.preserve {boolean} -- The flag to copy uid, gid, atime, and mtime of files. Default: false.
  • options.transform {((filepath: string) => stream.Transform)[]} -- Functions that creates a stream.Transform object to transform each copying file.
  • options.update {boolean} -- The flag to not overwrite files on destination if the source file is older. Default: false.
  • options.ignore {string|Array<string>} -- A gitignore style string or array of strings that make ignoring directory patterns easier. Default: []
• callback {(err: Error|null) => void} -- A function that is called at done.

Copy files that matches with source glob to dest directory.

cpx.copySync

cpx.copySync(source, dest, options)
cpx.copySync(source, dest)

A synchronous function of cpx.copy.

Arguments is almost same as cpx.copy. But options.transform is not supported.

cpx.watch

cpx.watch(source, dest, options)
cpx.watch(source, dest)

Copy files that matches with source glob string to dest directory. After the first copy, starts observing. And copy the files when every changes.

Arguments is same as cpx.copy.

cpx.watch returns an EventEmitter.

• .on("copy", (e) => { ... }) : Be fired after file is copied. e.srcPath is a path of original file. e.dstPath is a path of new file.
• .on("remove", (e) => { ... }) : Be fired after file is removed. e.path is a path of removed file.
• .on("watch-ready", () => { ... }) : Be fired when started watching files, after the first copying.
• .on("watch-error", (err) => { ... }) : Be fired when occured errors during watching.
