README

A Composer package which installs the CasperJS and PhantomJS binary (Linux, Windows, Mac) into the bin path of your project.

Installation

To install CasperJS and PhantomJS as a local, per-project dependency to your project, simply add a dependency on jerome-breton/casperjs-installer to your project's composer.json file.

{
    "require": {
        "jerome-breton/casperjs-installer": "dev-master"
    },
    "scripts": {
        "post-install-cmd": [
            "CasperJsInstaller\\Installer::install"
        ],
        "post-update-cmd": [
            "CasperJsInstaller\\Installer::install"
        ]
    }
}

For a development dependency, change require to require-dev.

The version number of the package specifies the CasperJS version! But for now, no versions of PhantomJS are prebuilt for 1.0.* versions, so for now, only dev-master is working, and will fetch the last 1.9.* PhantomJS version.

The download source used is: https://github.com/n1k0/casperjs/zipball/master

You can set the Composer configuration directive bin-dir to change the vendor binaries installation folder. Important! Composer will install the binaries into vendor\bin by default.

The scripts section is necessary, because currently Composer does not pass events to the handler scripts of dependencies. If you leave it away, you might execute the installer manually.

Now, assuming that the scripts section is set up as required, CasperJS and PhantomJS binary will be installed into the bin folder and updated alongside the project's Composer dependencies.

How does this work internally?

1. Fetching the CasperJS Installer In your composer.json you require the package "casperjs-installer". The package is fetched by composer and stored into ./vendor/jerome-breton/casperjs-installer. It contains only one file the CasperJsInstaller\\Installer.

2. Fetching PhantomJS This installer depends on jakoch/phantomjs-installer to install PhantomJS and follows the same strategy. This project has been created with major part of Jakoch work. The CasperJsInstaller will call Jakoch's PhantomJSInstaller\\Installer.

3. Platform-specific download of PhantomJS The PhantomInstaller\\Installer is run as a "post-install-cmd". That's why you need the "scripts" section in your "composer.json". The installer creates a new composer in-memory package "casperjs" and downloads the correct Phantom version to the folder ./vendor/jerome-breton/casperjs. All CasperJS files reside there, especially the samples.

4. Installation into bin folder A launcher is created to declare PhantomJS path and launch CasperJS from ./vendor/jerome-breton/casperjs to your composer configured bin-dir folder.
