A Composer package which installs the PhantomJS binary (Linux, Windows, Mac) into /bin
of your project.
To install PhantomJS as a local, per-project dependency to your project, simply add a dependency on jakoch/phantomjs-installer
to your project's composer.json
file.
{
"require": {
"jakoch/phantomjs-installer": "^3"
},
"config": {
"bin-dir": "bin"
},
"scripts": {
"post-install-cmd": [
"PhantomInstaller\\Installer::installPhantomJS"
],
"post-update-cmd": [
"PhantomInstaller\\Installer::installPhantomJS"
]
}
}
For a development dependency, change require
to require-dev
.
The default download source used is: https://bitbucket.org/ariya/phantomjs/downloads/ You might change it by setting a custom CDN URL, which is explained in the section "Downloading from a mirror".
By setting the Composer configuration directive bin-dir
, the vendor binaries will be installed into the defined 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, the PhantomJS binary
will be installed into the /bin
folder and updated alongside the project's Composer dependencies.
The environment and server variable PHANTOMJS_VERSION
enables you specify the version requirement at the time of packaging.
You can also set the phantomjs-version
in the extra
section of your composer.json
:
"extra": {
"jakoch/phantomjs-installer": {
"phantomjs-version": "2.1.1"
}
}
The search order for the version is 1) $_ENV, 2) $_SERVER, 3) composer.json
(extra section), 4) fallback to v2.1.1 (hardcoded latest version).
- Fetching the PhantomJS Installer
In your composer.json you require the package "phantomjs-installer".
The package is fetched by composer and stored into ./vendor/jakoch/phantomjs-installer
.
It contains only one file the PhantomInstaller\\Installer
.
- 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 "phantomjs",
detects your OS and downloads the correct Phantom version to the folder ./vendor/jakoch/phantomjs
.
All PhantomJS files reside there, especially the examples
.
- Installation into
/bin
folder
The binary is then copied from ./vendor/jakoch/phantomjs
to your composer configured bin-dir
folder.
- Generation of PhantomBinary
The installer generates a PHP file PhantomInstaller\\PhantomBinary
and inserts the path to the binary.
To access the binary and its folder easily, the class PhantomBinary
is created automatically during installation.
The class defines the constants BIN
and DIR
:
BIN
is the full-path to the PhantomJS binary file, e.g./your_project/bin/phantomjs
DIR
is the folder of the binary, e.g./your_project/bin
Both constants are also accessible via their getter-methods getBin()
and getDir()
.
Usage:
use PhantomInstaller\PhantomBinary;
// get values with class constants
$bin = PhantomInstaller\PhantomBinary::BIN;
$dir = PhantomInstaller\PhantomBinary::DIR;
// get values with static functions
$bin = PhantomInstaller\PhantomBinary::getBin();
$dir = PhantomInstaller\PhantomBinary::getDir();
This feature is similar to location.js
of the phantomjs module for Node.
The environment and server variables PHANTOMJS_PLATFORM
and PHANTOMJS_BITSIZE
enable you to
override the platform requirements at the time of packaging. This decouples the packaging system
from the target system. It allows to package on Linux for MacOSX or on Windows for Linux.
Possible values for
PHANTOMJS_PLATFORM
are:macosx
,windows
,linux
.PHANTOMJS_BITSIZE
are:32
or64
.
You can override the default download location of the PhantomJS binary file by setting it in one of these locations. Listed in order of precedence (highest first):
- The environment variable
PHANTOMJS_CDNURL
- The server variable
PHANTOMJS_CDNURL
- In your
composer.json
by using$['extra']['jakoch/phantomjs-installer']['cdnurl']
:
"extra": {
"jakoch/phantomjs-installer": {
"cdnurl": "https://github.com/Medium/phantomjs/releases/download/v1.9.19/"
}
},
Default Download Location
The default download location is Bitbucket: https://api.bitbucket.org/2.0/repositories/ariya/phantomjs/downloads/
.
You don't need to set it explicitly. It's used, when PHANTOMJS_CDNURL
is not set.
Mirrors
You might use one of the following mirror URLs as a value for PHANTOMJS_CDNURL
:
https://cnpmjs.org/downloads/
- USA, San Mateo (47.88.189.193)https://npm.taobao.org/mirrors/phantomjs/
- China, Hangzhou (114.55.80.225)https://github.com/Medium/phantomjs/
- USA, San Francisco (192.30.253.113)
This list of mirrors is not complete. If you know another mirror, please don't hesitate to add it here.
The mirror URLs are also not hardcoded, except for the Github URL.
This enables you to point to any PhantomJS mirror or download folder you like.
For instance, you could point to the URL of the download folder of your company, where the binaries are stored:
PHANTOMJS_CDNURL=https://cdn.company.com/downloads/phantomjs/
.
In case downloading an archive fails with HttpStatusCode 404 (resource not found),
the downloader will automatically lower the version to the next available version
and retry. The number of retries is determined by the number of hardcoded PhantomJS
versions in getPhantomJSVersions()
. This feature was added, because of the problems
with v2.0.0 not being available for all platforms (see issue #25).
