Class JavaScriptModuleConfiguration

java.lang.Object

org.apache.tapestry5.services.javascript.JavaScriptModuleConfiguration

public final class JavaScriptModuleConfiguration
extends Object

Used to define a module shim, used to adapt non-AMD JavaScript libraries to operate like proper modules. This information is used to build up a list of dependencies for the contributed JavaScript module, and to identify the resource to be streamed to the client. Instances of this class are contributed to the ModuleManager service; the contribution key is the module name (typically, a single word). In some cases, an instance may be created and contributed to override a default module; if the module has no dependencies, exports, or initExpression (that is, if it is a proper AMD module, where such dependencies are provided inside the module itself), then no client-side shim configuration will be written for the module, but requests for the module will be satisfied by the resource.'

Modifier and Type	Method	Description
JavaScriptModuleConfiguration	dependsOn(String... moduleNames)	A list of other module names the shim depends on.
JavaScriptModuleConfiguration	exports(String exports)	The name of a global variable exported by the module.
List<String>	getDependencies()
String	getExports()
String	getInitExpression()
boolean	getNeedsConfiguration()	Returns true if the module contains any additional configuration beyond its Resource.
JavaScriptModuleConfiguration	initializeWith(String expression)	Used as an alternative to exports(String), this allows a short expression to be specified; the expression is used to initialize, clean up, and (usually) return the module's export value.

Field Detail

resource

public final Resource resource

The resource for this shim module.

Constructor Detail

JavaScriptModuleConfiguration

public JavaScriptModuleConfiguration(Resource resource)

Method Detail

dependsOn

public JavaScriptModuleConfiguration dependsOn(String... moduleNames)

A list of other module names the shim depends on.

Parameters:

moduleNames -

Returns:

this JavaScriptModuleConfiguration for further configuration

getDependencies

public List<String> getDependencies()

exports

public JavaScriptModuleConfiguration exports(String exports)

The name of a global variable exported by the module. This will be the value injected into modules that depend on the shim.

Returns:

this JavaScriptModuleConfiguration for further configuration

getExports

public String getExports()

initializeWith

public JavaScriptModuleConfiguration initializeWith(String expression)

Used as an alternative to exports(String), this allows a short expression to be specified; the expression is used to initialize, clean up, and (usually) return the module's export value. For Underscore, this would be "_.noConflict()". If the expression returns null, then the exports value is used. In RequireJS 2.1.1 (the version shipped with Tapestry, currently), an init function is not invoked unless the shim also defines an exports. See RequireJS issue 517. At this time, you should specify exports even if you provide a initializeWith(String)}.

Parameters:

expression - initialization expression

Returns:

this JavaScriptModuleConfiguration, for further configuration

getInitExpression

public String getInitExpression()

getNeedsConfiguration

public boolean getNeedsConfiguration()

Returns true if the module contains any additional configuration beyond its Resource.
