Plugin.xml reference documentation
Plugin.xml file defines the structure and settings required for your plugin. It has several elements to provide details about your plugin.
The plugin
element is the plugin manifest's top-level element.
Attributes(type) | Description |
---|---|
xmlns(string) | Required The plugin namespace, http://apache.org/cordova/ns/plugins/1.0 . If the document contains XML from other namespaces, such as tags to be added to the AndroidManifest.xml file in the case of Android, those namespaces should also be included in the element. |
id(string) | Required A npm-style identifier for the plugin. |
version(string) | Required A version number for the plugin. Semver syntax is supported. |
Example:
<?xml version="1.0" encoding="UTF-8"?>
<plugin xmlns="http://apache.org/cordova/ns/plugins/1.0"
xmlns:android="http://schemas.android.com/apk/res/android"
id="my-plugin-id"
version="1.0.2">
engines and engine
The child elements of the <engines>
element specify versions of Apache Cordova-based frameworks that this plugin supports. The CLI aborts with a non-zero code for any plugin whose target project does not meet the engine's constraints. If no tags are specified, the CLI attempts to install into the specified cordova project directory blindly.
NOTE: In Cordova 6.1.0+, the recommended place to specify platform, plugin, and CLI dependencies is in a plugin's
package.json
. See specifying Cordova dependencies for more information
Attributes(type) | Description |
---|---|
name(string) | Required Name of the engine. Here are the default engines that are supported :
|
version(string) | Required The version that your framework must have in order to install. Semver syntax is supported. |
scriptSrc(string) | For custom frameworks only Required The script file that tells plugman the version of the custom framework. Ideally, this file should be within the top level directory of your plugin directory. |
platform(string) | For custom frameworks only Required The platforms your framework supports. You may use the wildcard * to say supported for all platforms, specify multiple with a pipe character like `android |
Examples:
<engines>
<engine name="cordova-android" version="=1.8.0" />
</engines>
Engine elements may also specify fuzzy matches using '>', '>=' etc. to avoid repetition, and to reduce maintenance when the underlying platform is updated.
<engines>
<engine name="cordova-android" version=">=1.8.0" />
</engines>
The <engine>
tags also has default support for all of the main platforms Cordova exists on. Specifying the cordova engine tag means that all versions of Cordova on any platform must satisfy the engine version attribute. You may also list specific platforms and their versions in order to override the catch-all cordova engine:
<engines>
<engine name="cordova" version=">=1.7.0" />
<engine name="cordova-android" version=">=1.8.0" />
<engine name="cordova-ios" version=">=1.7.1" />
</engines>
Custom frameworks example:
<engines>
<engine name="my_custom_framework" version="1.0.0" platform="android" scriptSrc="path_to_my_custom_framework_version"/>
<engine name="another_framework" version=">0.2.0" platform="ios|android" scriptSrc="path_to_another_framework_version"/>
<engine name="even_more_framework" version=">=2.2.0" platform="*" scriptSrc="path_to_even_more_framework_version"/>
</engines>
name
The name
element is used to specify the name of the plugin. This element does not (yet) handle localization.
Example:
<name>Foo</name>
description
The description
element is used to specify the description of the plugin. This element does not (yet) handle localization.
Example:
<description>Foo plugin description</description>
author
The content of the author
element contains the name of the plugin author.
Example:
<author>Foo plugin author</author>
keywords
The content of the keywords
element contains comma separated keywords to describe the plugin.
Example:
<keywords>foo,bar</keywords>
license
This element is used to specify the license of the plugin.
Example:
<license>Apache 2.0 License</license>
asset
This element is used to list the files or directories to be copied into a Cordova app's www
directory. Any <asset>
elements that are nested within <platform>
elements specify platform-specific web assets.
Attributes(type) | Description |
---|---|
src(string) | Required Where the file or directory is located in the plugin package, relative to the plugin.xml document. If a file does not exist at the specified src location, the CLI stops and reverses the installation process, issues a notification about the conflict, and exits with a non-zero code. |
target(string) | Required Where the file or directory should be located in the Cordova app, relative to the www directory. If a file already exists at the target location, the CLI stops and reverses the installation process, issues a notification about the conflict, and exits with a non-zero code. |
Examples:
<!-- a single file, to be copied in the root directory -->
<asset src="www/foo.js" target="foo.js" />
<!-- a directory, also to be copied in the root directory -->
<asset src="www/foo" target="foo" />
Assets can be targeted to subdirectories as well. This will create the js/experimental
directory within the www
directory, unless already present, and copy the new-foo.js
file and renames it to foo.js
.
<asset src="www/new-foo.js" target="js/experimental/foo.js" />
js-module
Most plugins include one or more JavaScript files. Each <js-module>
tag corresponds to a JavaScript file, and prevents the plugin's users from having to add a <script>
tag for each file. Do not wrap the file with cordova.define, as it is added automatically. The module is wrapped in a closure, with module, exports, and require in scope, as is normal for AMD modules. Nesting <js-module>
elements within <platform>
declares platform-specific JavaScript module bindings.
Attributes(type) | Description |
---|---|
src(string) | References a file in the plugin directory relative to the plugin.xml file. If src does not resolve to an existing file, the CLI stops and reverses the installation, issues a notification of the problem, and exits with a non-zero code. |
name(string) | Provides the last part of the module name. It can generally be whatever you like, and it only matters if you want to use cordova.require to import other parts of your plugins in your JavaScript code. The module name for a <js-module> is your plugin's id followed by the value of name. |
Example:
When installing a plugin with the example below, socket.js is copied to www/plugins/my-plugin-id/socket.js
, and added as an entry to www/cordova_plugins.js
. At load time, code in cordova.js
uses XHR to read each file and inject a <script>
tag into HTML.
<js-module src="socket.js" name="Socket">
</js-module>
Also for this example, with a plugin id of chrome-socket
, the module name will be chrome-socket.Socket
.
clobbers
Allowed within <js-module>
element. Used to specify the namespace under window
object where module.exports gets inserted. You can have as many <clobbers>
as you like. Any object not available on window
is created.
Attributes(type) | Description |
---|---|
target(string) | The namespace where module.exports gets inserted to. |
Example:
<js-module src="socket.js" name="Socket">
<clobbers target="chrome.socket" />
</js-module>
Here module.exports gets inserted into the window
object as window.chrome.socket
.
merges
Allowed within <js-module>
element. Used to specify the namespace under window
object where module.exports gets merged with any existing value. If any key already exists, the module's version overrides the original. You can have as many <merges>
as you like. Any object not available on window
is created.
Attributes(type) | Description |
---|---|
target(string) | The namespace which module.exports gets merged to. |
Example:
<js-module src="socket.js" name="Socket">
<merges target="chrome.socket" />
</js-module>
Here module.exports gets merged with any existing value at window.chrome.socket
.
runs
Allowed within <js-module>
element. It implies that your code should be specified with cordova.require
, but not installed on the window
object. This is useful when initializing the module, attaching event handlers or otherwise. You can only have up to one <runs/>
tag. Note that including a <runs/>
with <clobbers/>
or <merges/>
is redundant, since they also cordova.require
your module.
Example:
<js-module src="socket.js" name="Socket">
<runs/>
</js-module>
dependency
The <dependency>
tag allows you to specify other plugins on which the current plugin depends. The plugins are referenced by their unique npm ids or by github url.
Attributes(type) | Description |
---|---|
id(string) | Provides the ID of the plugin. |
url(string) | A URL for the plugin. This should reference a git repository, which the CLI attempts to clone. |
commit(string) | This is any git reference understood by git checkout : a branch or tag name (e.g., master , 0.3.1 ), or a commit hash (e.g., 975ddb228af811dd8bb37ed1dfd092a3d05295f9 ). |
subdir(string) | Specifies that the targeted plugin dependency exists as a subdirectory of the git repository. This is helpful because it allows the repository to contain several related plugins, each specified individually. If you set the url of a <dependency> tag to "." and provide a subdir , the dependent plugin is installed from the same local or remote git repository as the parent plugin that specifies the <dependency> tag.Note that the subdir always specifies a path relative to the root of the git repository, not the parent plugin. This is true even if you installed the plugin with a local path directly to it.The CLI finds the root of the git repository and then finds the other plugin from there. |
version(string) | The version of the plugin depended on. Semver syntax is supported. |
Examples:
<dependency id="cordova-plugin-someplugin" url="https://github.com/myuser/someplugin" commit="428931ada3891801" subdir="some/path/here" />
<dependency id="cordova-plugin-someplugin" version="1.0.1">
platform
Identifies platforms that have associated native code or require modifications to their configuration files. Tools using this specification can identify supported platforms and install the code into Cordova projects. Plugins without <platform>
tags are assumed to be JavaScript-only, and therefore installable on any and all platforms.
Attributes(type) | Description |
---|---|
name(string) | Required Allowed values: ios, android, blackberry10, amazon-fireos, wp8, windows Identifies a platform as supported, associating the element's children with that platform. |
Example:
<platform name="android">
<!-- android-specific elements -->
</platform>
source-file
Identifies executable source code that should be installed into a project.
Attributes(type) | Description |
---|---|
src(string) | Required Location of the file relative to plugin.xml . If the src file can't be found, the CLI stops and reverses the installation, issues a notification about the problem, and exits with a non-zero code. |
target-dir(string) | A directory into which the files should be copied, relative to the root of the Cordova project. In practice, this is most important for Java-based platforms, where a file in the com.alunny.foo package must be located within the com/alunny/foo directory. For platforms where the source directory is not important, this attribute should be omitted. |
framework(boolean) | Default: false iOS If set to true, also adds the specified file as a framework to the project. |
compiler-flags(string) | iOS If set, assigns the specified compiler flags for the particular source file. |
Examples:
<!-- android -->
<source-file src="src/android/Foo.java" target-dir="src/com/alunny/foo" />
<!-- ios -->
<source-file src="src/ios/CDVFoo.m" />
<source-file src="src/ios/someLib.a" framework="true" />
<source-file src="src/ios/someLib.a" compiler-flags="-fno-objc-arc" />
header-file
This is like <source-file>
element but specifically for platforms such as iOS and Android that distinguish between source files, headers, and resources. This is not supported by Windows.
Attributes(type) | Description |
---|---|
src(string) | Required Location of the file relative to plugin.xml . If the src file can't be found, the CLI stops and reverses the installation, issues a notification about the problem, and exits with a non-zero code. |
target(string) | Path to where the file will be copied in your directory. |
Example:
For iOS:
<header-file src="CDVFoo.h" />
resource-file
This is like <source-file>
element, but specifically for platforms such as iOS and Android that distinguish between source files, headers, and resources.
Attributes(type) | Description |
---|---|
src(string) | Required Location of the file relative to plugin.xml . If the src file can't be found, the CLI stops and reverses the installation, issues a notification about the problem, and exits with a non-zero code. |
target(string) | Path to where the file will be copied in your directory. |
arch(string) | windows Allowed values: x86 , x64 or ARM .Indicates that the file should only be included when building for the specified architecture. |
device-target | windows Allowed values: win (or windows ), phone or all .Indicates that the file should only be included when building for the specified target device type. |
versions | windows Indicates that the file should only be included when building for versions that match the specified version string. Value can be any valid node semantic version range string. |
Examples:
For Android:
<resource-file src="FooPluginStrings.xml" target="res/values/FooPluginStrings.xml" />
For Windows:
<resource-file src="src/windows/win81/MobServices.pri" target="win81/MobServices.pri" device-target="windows" versions="8.1" arch="x64"/>
config-file
Identifies an XML-based configuration file to be modified, where in that document the modification should take place, and what should be modified. Two file types that have been tested for modification with this element are xml
and plist
files. The config-file
element only allows you to append new children to an XML document tree. The children are XML literals to be inserted in the target document.
Attributes(type) | Description |
---|---|
target(string) | The file to be modified, and the path relative to the root of the Cordova project. If the specified file does not exist, the tool ignores the configuration change and continues installation. The target can include wildcard ( * ) elements. In this case, the CLI recursively searches through the project directory structure and uses the first match.On iOS, the location of configuration files relative to the project directory root is not known, so specifying a target of config.xml resolves to cordova-ios-project/MyAppName/config.xml . |
parent(string) | An XPath selector referencing the parent of the elements to be added to the config file. If you use absolute selectors, you can use a wildcard (* ) to specify the root element, e.g., /*/plugins . If the selector does not resolve to a child of the specified document, the tool stops and reverses the installation process, issues a warning, and exits with a non-zero code.For plist files, the parent determines under what parent key the specified XML should be inserted. |
after(string) | A prioritized list of accepted siblings after which to add the XML snippet. Useful for specifying changes in files which require strict ordering of XML elements like this. |
device-target(string) | windows Allowed values: win , phone , all .Applicable when affecting the meta-name package.appxmanifest , this attribute indicates that the file should only be modified when building for the specified target device type. |
versions(string) | windows Applicable when affecting the meta-name package.appxmanifest , this attribute indicates that app manifests for specific Windows versions should only be altered for versions that match the specified version string. Value can be any valid node semantic version range string. |
Examples:
For XML:
<config-file target="AndroidManifest.xml" parent="/manifest/application">
<activity android:name="com.foo.Foo" android:label="@string/app_name">
<intent-filter>
</intent-filter>
</activity>
</config-file>
For plist
:
<config-file target="*-Info.plist" parent="CFBundleURLTypes">
<array>
<dict>
<key>PackageName</key>
<string>$PACKAGE_NAME</string>
</dict>
</array>
</config-file>
For windows-specific attributes:
<config-file target="package.appxmanifest" parent="/Package/Capabilities" versions="<8.1.0">
<Capability Name="picturesLibrary" />
<DeviceCapability Name="webcam" />
</config-file>
<config-file target="package.appxmanifest" parent="/Package/Capabilities" versions=">=8.1.0" device-target="phone">
<DeviceCapability Name="webcam" />
</config-file>
The above example will set pre-8.1 platforms (Windows 8, specifically) to require the webcam
device capability and the picturesLibrary
general capability, and apply the webcam
device capability only to Windows 8.1 projects that build for Windows Phone. Windows desktop 8.1 systems are unmodified.
plugins-plist
Specifies a key and value to append to the correct AppInfo.plist
file in an iOS Cordova project. This is outdated as it only applies to cordova-ios 2.2.0 and below. Use the <config-file>
tag for newer versions of Cordova.
Example:
<plugins-plist key="Foo" string="CDVFoo" />
lib-file
Like source, resource, and header files, but specifically for platforms such as BlackBerry 10 that use user-generated libraries. For the Windows platform, the <lib-file>
element allows the inclusion of an <SDKReference>
in the generated Windows project files.
Attributes(type) | Description |
---|---|
src(string) | Required The location of the file relative to plugin.xml . If src can't be found, the CLI stops and reverses the installation, issues a warning about the problem, and exits with a non-zero code.For Windows, it indicates the name of the SDK to include (which will be used as value of the Include attribute of the generated <SDKReference> element). |
arch(string) | The architecture for which the .so file has been built, either device or simulator .For Windows, it indicates that the <SDKReference> should only be included when building for the specified architecture. Supported values are x86 , x64 or ARM . |
device-target(string) | windows Allowed values: win (or windows ), phone or all .Indicates that the <SDKReference> should only be included when building for the specified target device type. |
versions(string) | windows Indicates that the <SDKReference> should only be included when building for versions that match the specified version string. Value can be any valid node semantic version range string. |
Examples:
<lib-file src="src/BlackBerry10/native/device/libfoo.so" arch="device" />
<lib-file src="src/BlackBerry10/native/simulator/libfoo.so" arch="simulator" />
For Windows:
<lib-file src="Microsoft.WinJS.2.0, Version=1.0" arch="x86" />
<lib-file src="Microsoft.WinJS.2.0, Version=1.0" versions=">=8.1" />
<lib-file src="Microsoft.WinJS.2.0, Version=1.0" target="phone" />
<lib-file src="Microsoft.WinJS.2.0, Version=1.0" target="win" versions="8.0" arch="x86" />
framework
Identifies a framework (usually part of the OS/platform) on which the plugin depends.
Attributes(type) | Description |
---|---|
src(string) | Required The name of the system framework or the relative path to one which is included as part of your plugin files. |
custom(boolean) | Indicates whether the framework is included as part of your plugin files. |
weak(boolean) | Default: false Indicates whether the framework should be weakly linked. |
type(string) | Indicates the type of framework to add. |
parent(string) | Default: . Sets the relative path to the directory containing the sub-project to which to add the reference. The default, . , implies the application project. |
arch(string) | windows Allowed values: x86 , x64 or ARM .Indicates that the framework should only be included when building for the specified architecture. |
device-target(string) | windows Allowed values: win (or windows ), phone or all .Indicates that the framework should only be included when building for the specified target device type. |
versions(string) | windows Indicates that the framework should only be included when building for versions that match the specified version string. Value can be any valid node semantic version range string. |
target-dir(string) | windows Indicates a subdirectory into which the framework should be copied. In practice, this is most important when plugin contains different framework versions for different chip architectures or device targets, but which have the same name. This allows you to specify different subfolders for each framework version so that they don't overlap each other. |
Examples:
For iOS:
<framework src="libsqlite3.dylib" />
<framework src="social.framework" weak="true" />
<framework src="relative/path/to/my.framework" custom="true" />
On Android (as of cordova-android@4.0.0), framework tags are used to include Maven dependencies, or to include bundled library projects.
<!-- Depend on latest version of GCM from play services -->
<framework src="com.google.android.gms:play-services-gcm:+" />
<!-- Depend on v21 of appcompat-v7 support library -->
<framework src="com.android.support:appcompat-v7:21+" />
<!-- Depend on library project included in plugin -->
<framework src="relative/path/FeedbackLib" custom="true" />
Framework can also be used to have custom .gradle files sub-included into the main project's .gradle file:
<framework src="relative/path/rules.gradle" custom="true" type="gradleReference" />
On Windows, using custom='true'
and type='projectReference'
will add a reference to the project which will be added to the compile+link steps of the cordova project. This essentially is the only way currently that a 'custom' framework can target multiple architectures as they are explicitly built as a dependency by the referencing cordova application.
<framework src="path/to/project/LibProj.csproj" custom="true" type="projectReference"/>
Examples of using these Windows specific attributes:
<framework src="src/windows/example.dll" arch="x64" />
<framework src="src/windows/example.dll" versions=">=8.0" />
<framework src="src/windows/example.vcxproj" type="projectReference" target="win" />
<framework src="src/windows/example.vcxproj" type="projectReference" target="all" versions="8.1" arch="x86" />
<framework src="src/windows/example.dll" target-dir="bin/x64" arch="x64" custom="true"/>
info
Additional information provided to users. This is useful when you require extra steps that can't be easily automated or are beyond the CLI's scope. The contents of this tag gets printed out when the CLI installs the plugin.
Example:
<info>
You need to install __Google Play Services__ from the `Android Extras` section using the Android SDK manager (run `android`).
You need to add the following line to the `local.properties`:
android.library.reference.1=PATH_TO_ANDROID_SDK/sdk/extras/google/google_play_services/libproject/google-play-services_lib
</info>
hook
Represents your custom script which will be called by Cordova when certain action occurs (for example, after plugin is added or platform prepare logic is invoked). This is useful when you need to extend default Cordova functionality. See Hooks Guide for more information.
Example:
<hook type="after_plugin_install" src="scripts/afterPluginInstall.js" />
uses-permission
In certain cases, a plugin may need to make configuration changes dependent on the target application. For example, to register for C2DM on Android, an app whose package id is my-app-id
would require a permission such as:
<uses-permission android:name="my-app-id.permission.C2D_MESSAGE"/>
In such cases where the content inserted from the plugin.xml
file is not known ahead of time, variables can be indicated by a dollar-sign followed by a series of capital letters, digits, or underscores. For the above example, the plugin.xml
file would include this tag:
<uses-permission android:name="$PACKAGE_NAME.permission.C2D_MESSAGE"/>
The CLI replaces variable references with the specified value, or the empty string if not found. The value of the variable reference may be detected (in this case, from the AndroidManifest.xml
file) or specified by the user of the tool; the exact process is dependent on the particular tool.
Plugman can request users to specify a plugin's required variables. For example, API keys for C2M and Google Maps can be specified as a command-line argument:
plugman --platform android --project /path/to/project --plugin name|git-url|path --variable API_KEY=!@CFATGWE%^WGSFDGSDFW$%^#$%YTHGsdfhsfhyer56734
Certain variable names should be reserved, like $PACKAGE_NAME
. This is the reverse-domain style unique identifier for the package, corresponding to the CFBundleIdentifier
on iOS or the package
attribute of the top-level manifest
element in an AndroidManifest.xml
file.
preference
As seen in the previous section, sometimes plugin might require user to specify values for their variables. To make those variable mandatory, the <platform>
tag needs to contain a <preference>
tag. The CLI checks that these required preferences are passed in. If not, it should warn the user how to pass the variable in and exit with a non-zero code.
Attributes(type) | Description |
---|---|
name(string) | Required Name of the variable. |
default(string) | Default value of the variable. If present, its value will be used and no error will be emitted in case user does not enter any value. |
Example:
<preference name="API_KEY" default="default-value" />
