trucker

Trucker is a command-line tool that helps manage dependencies between javascript files

It works with CommonJS require (for example: node.js or browserify source files) and with ECMAScript 6 import.

It has two main functions:

1. Show all inbound and outbound dependencies for javascript and coffeescript source files. (trucker --info filename.js or trucker -i filename.js)

2. Move/rename source files while fixing up the paths used in requires. (trucker --move source destination or trucker -m source destination)

Why is it called trucker? Because it hauls your files around without breaking them.

Installation

npm install -g trucker

Trucker requires node.js 0.12 or greater.

The unit tests use block scoping and arrow functions, so they require Node 4+.

Usage

To move files:

trucker --move [flags] source [additional sources...] destination

To get info about files:

trucker --info [optional file paths]

If no paths are passed, trucker will spit out information for all files in the base path (see options below).

Examples

in the examples directory (provided), you can try the following (add -n for dry run mode if desired):

• Get info about all dependencies in the current directory and all sub directories

trucker --info

• Get dependencies for just one subdirectory

trucker -i stark/

• Move a single file:

trucker --move stark/eddard.js deceased/

• Move a single file, specifying destination path:

trucker -m stark/eddard.js deceased/ned.js

• Move multiple files explicitly

trucker -m stark/eddard.js tully/catelyn.js deceased/

• Move a directory:

trucker -m stark deceased/stark

• Paths are automatically created:

trucker -m stark/eddard.js deceased/in/book1/

Options

-h, --help prints the help

-n, --dry-run tells trucker not to move any files, but to instead print out a list of all of the changes that would have been made if this option was not set.

-s, --scope can be used to expand or contract the set of files that trucker searches for dependencies. This defaults to the present working directory. If you have a very large project you may wish to constrain the scope for performance reasons (analysis takes time), or in some cases you may wish to expand the scope beyond the current directory. Use --scope for this.

-q, --quiet suppress output

Supported file types

Trucker supports javascript and coffeescript source files. It can handle projects that have both of these file types intermixed.

Ignored files

Trucker ignores files using the first .gitignore it finds, starting from the base directory (usually cwd), and ascending to the root.

Limitations

Tested on OSX

Should also work on other platforms. Let me know if you have a problem.

require syntax

Trucker only recognizes basic require syntax.

Trucker doesn't recognize this, for example:

var x = '../foo/bar';
var y = require(x);
