# Cordova Hooks
Cordova Hooks represent special scripts which could be added by application and plugin developers or even by your own build system to customize cordova commands. Hook scripts could be defined by adding them to the special predefined folder (`/hooks`) or via configuration files (`config.xml` and `plugin.xml`) and run serially in the following order:
* Application hooks from `/hooks`;
* Application hooks from `config.xml`;
* Plugin hooks from `plugins/.../plugin.xml`.
__Remember__: Make your scripts executable.
__Note__: `.cordova/hooks` directory is also supported for backward compatibility, but we don't recommend using it as it is deprecated.
## Supported hook types
The following hook types are supported:
after_build/
after_compile/
after_docs/
after_emulate/
after_platform_add/
after_platform_rm/
after_platform_ls/
after_plugin_add/
after_plugin_ls/
after_plugin_rm/
after_plugin_search/
after_plugin_install/ <-- Plugin hooks defined in plugin.xml are executed exclusively for a plugin being installed
after_prepare/
after_run/
after_serve/
before_build/
before_compile/
before_docs/
before_emulate/
before_platform_add/
before_platform_rm/
before_platform_ls/
before_plugin_add/
before_plugin_ls/
before_plugin_rm/
before_plugin_search/
before_plugin_install/ <-- Plugin hooks defined in plugin.xml are executed exclusively for a plugin being installed
before_plugin_uninstall/ <-- Plugin hooks defined in plugin.xml are executed exclusively for a plugin being uninstalled
before_prepare/
before_run/
before_serve/
pre_package/ <-- Windows 8 and Windows Phone only.
## Ways to define hooks
### Via '/hooks' directory
To execute custom action when corresponding hook type is fired, use hook type as a name for a subfolder inside 'hooks' directory and place you script file here, for example:
# script file will be automatically executed after each build
hooks/after_build/after_build_custom_action.js
### Config.xml
Hooks can be defined in project's `config.xml` using `<hook>` elements, for example:
<hook type="before_build" src="scripts/appBeforeBuild.bat" />
<hook type="before_build" src="scripts/appBeforeBuild.js" />
<hook type="before_plugin_install" src="scripts/appBeforePluginInstall.js" />
<platform name="wp8">
<hook type="before_build" src="scripts/wp8/appWP8BeforeBuild.bat" />
<hook type="before_build" src="scripts/wp8/appWP8BeforeBuild.js" />
<hook type="before_plugin_install" src="scripts/wp8/appWP8BeforePluginInstall.js" />
...
</platform>
<platform name="windows8">
<hook type="before_build" src="scripts/windows8/appWin8BeforeBuild.bat" />
<hook type="before_build" src="scripts/windows8/appWin8BeforeBuild.js" />
<hook type="before_plugin_install" src="scripts/windows8/appWin8BeforePluginInstall.js" />
...
</platform>
### Plugin hooks (plugin.xml)
As a plugin developer you can define hook scripts using `<hook>` elements in a `plugin.xml` like that:
<hook type="before_plugin_install" src="scripts/beforeInstall.js" />
<hook type="after_build" src="scripts/afterBuild.js" />
<platform name="wp8">
<hook type="before_plugin_install" src="scripts/wp8BeforeInstall.js" />
<hook type="before_build" src="scripts/wp8BeforeBuild.js" />
...
</platform>
`before_plugin_install`, `after_plugin_install`, `before_plugin_uninstall` plugin hooks will be fired exclusively for the plugin being installed/uninstalled.
## Script Interface
### Javascript
If you are writing hooks in Javascript you should use the following module definition:
```javascript
module.exports = function(context) {
...
}
```
You can make your scipts async using Q:
```javascript
module.exports = function(context) {
var Q = context.requireCordovaModule('q');
var deferral = new Q.defer();
setTimeout(function(){
console.log('hook.js>> end');
deferral.resolve();
}, 1000);
return deferral.promise;
}
```
`context` object contains hook type, executed script full path, hook options, command-line arguments passed to Cordova and top-level "cordova" object:
```json
{
"hook": "before_plugin_install",
"scriptLocation": "c:\\script\\full\\path\\appBeforePluginInstall.js",
"cmdLine": "The\\exact\\command\\cordova\\run\\with arguments",
"opts": {
"projectRoot":"C:\\path\\to\\the\\project",
"cordova": {
"platforms": ["wp8"],
"plugins": ["com.plugin.withhooks"],
"version": "0.21.7-dev"
},
"plugin": {
"id": "com.plugin.withhooks",
"pluginInfo": {
...
},
"platform": "wp8",
"dir": "C:\\path\\to\\the\\project\\plugins\\com.plugin.withhooks"
}
},
"cordova": {...}
}
```
`context.opts.plugin` object will only be passed to plugin hooks scripts.
You can also require additional Cordova modules in your script using `context.requireCordovaModule` in the following way:
```javascript
var Q = context.requireCordovaModule('q');
```
__Note__: new module loader script interface is used for the `.js` files defined via `config.xml` or `plugin.xml` only.
For compatibility reasons hook files specified via `/hooks` folders are run via Node child_process spawn, see 'Non-javascript' section below.
### Non-javascript
Non-javascript scripts are run via Node child_process spawn from the project's root directory and have the root directory passes as the first argument. All other options are passed to the script using environment variables:
* CORDOVA_VERSION - The version of the Cordova-CLI.
* CORDOVA_PLATFORMS - Comma separated list of platforms that the command applies to (e.g.: android, ios).
* CORDOVA_PLUGINS - Comma separated list of plugin IDs that the command applies to (e.g.: org.apache.cordova.file, org.apache.cordova.file-transfer)
* CORDOVA_HOOK - Path to the hook that is being executed.
* CORDOVA_CMDLINE - The exact command-line arguments passed to cordova (e.g.: cordova run ios --emulate)
If a script returns a non-zero exit code, then the parent cordova command will be aborted.
## Writing hooks
We highly recommend writing your hooks using Node.js so that they are
cross-platform. Some good examples are shown here:
[http://devgirl.org/2013/11/12/three-hooks-your-cordovaphonegap-project-needs/](http://devgirl.org/2013/11/12/three-hooks-your-cordovaphonegap-project-needs/)
Also, note that even if you are working on Windows, and in case your hook scripts aren't bat files (which is recommended, if you want your scripts to work in non-Windows operating systems) Cordova CLI will expect a shebang line as the first line for it to know the interpreter it needs to use to launch the script. The shebang line should match the following example:
#!/usr/bin/env [name_of_interpreter_executable]

* Holds the sockets and streams of an HTTP, HTTPS, or HTTPS+SPDY connection,

* <p>Typically instances of this class are created, connected and exercised
* automatically by the HTTP client. Applications may use this class to monitor
* HTTP connections as members of a {@link ConnectionPool connection pool}.
*
* <p>Do not confuse this class with the misnamed {@code HttpURLConnection},
* which isn't so much a connection as a single request/response exchange.
*
* <h3>Modern TLS</h3>
* There are tradeoffs when selecting which options to include when negotiating
* a secure connection to a remote host. Newer TLS options are quite useful:
* <ul>
* <li>Server Name Indication (SNI) enables one IP address to negotiate secure
* connections for multiple domain names.
* <li>Next Protocol Negotiation (NPN) enables the HTTPS port (443) to be used
* for both HTTP and SPDY transports.
* </ul>
* Unfortunately, older HTTPS servers refuse to connect when such options are
* presented. Rather than avoiding these options entirely, this class allows a
* connection to be attempted with modern options and then retried without them
* should the attempt fail.

/**
* Caches HTTP and HTTPS responses to the filesystem so they may be reused,
* saving time and bandwidth.
*
* <h3>Cache Optimization</h3>
* To measure cache effectiveness, this class tracks three statistics:
* <ul>
* <li><strong>{@link #getRequestCount() Request Count:}</strong> the number
* of HTTP requests issued since this cache was created.
* <li><strong>{@link #getNetworkCount() Network Count:}</strong> the
* number of those requests that required network use.
* <li><strong>{@link #getHitCount() Hit Count:}</strong> the number of
* those requests whose responses were served by the cache.
* </ul>
* Sometimes a request will result in a conditional cache hit. If the cache
* contains a stale copy of the response, the client will issue a conditional
* {@code GET}. The server will then send either the updated response if it has
* changed, or a short 'not modified' response if the client's copy is still
* valid. Such responses increment both the network count and hit count.
*
* <p>The best way to improve the cache hit rate is by configuring the web
* server to return cacheable responses. Although this client honors all <a
* href="http://www.ietf.org/rfc/rfc2616.txt">HTTP/1.1 (RFC 2068)</a> cache
* headers, it doesn't cache partial responses.
*
* <h3>Force a Network Response</h3>
* In some situations, such as after a user clicks a 'refresh' button, it may be
* necessary to skip the cache, and fetch data directly from the server. To force
* a full refresh, add the {@code no-cache} directive: <pre> {@code
* connection.addRequestProperty("Cache-Control", "no-cache");
* }</pre>
* If it is only necessary to force a cached response to be validated by the
* server, use the more efficient {@code max-age=0} instead: <pre> {@code
* connection.addRequestProperty("Cache-Control", "max-age=0");
* }</pre>
*
* <h3>Force a Cache Response</h3>
* Sometimes you'll want to show resources if they are available immediately,
* but not otherwise. This can be used so your application can show
* <i>something</i> while waiting for the latest data to be downloaded. To
* restrict a request to locally-cached resources, add the {@code
* only-if-cached} directive: <pre> {@code
* try {
* connection.addRequestProperty("Cache-Control", "only-if-cached");
* InputStream cached = connection.getInputStream();

* A cache that uses a bounded amount of space on a filesystem. Each cache

* accessible as streams or files. Each value must be between {@code 0} and
* {@code Integer.MAX_VALUE} bytes in length.
*
* <p>The cache stores its data in a directory on the filesystem. This
* directory must be exclusive to the cache; the cache may delete or overwrite
* files from its directory. It is an error for multiple processes to use the
* same cache directory at the same time.
*
* <p>This cache limits the number of bytes that it will store on the
* filesystem. When the number of stored bytes exceeds the limit, the cache will
* remove entries in the background until the limit is satisfied. The limit is
* not strict: the cache may temporarily exceed it while waiting for files to be
* deleted. The limit does not include filesystem overhead or the cache
* journal so space-sensitive applications should set a conservative limit.
*
* <p>Clients call {@link #edit} to create or update the values of an entry. An
* entry may have only one editor at one time; if a value is not available to be
* edited then {@link #edit} will return null.
* <ul>
* <li>When an entry is being <strong>created</strong> it is necessary to
* supply a full set of values; the empty value should be used as a
* placeholder if necessary.
* <li>When an entry is being <strong>edited</strong>, it is not necessary
* to supply data for every value; values default to their previous
* value.
* </ul>
* Every {@link #edit} call must be matched by a call to {@link Editor#commit}
* or {@link Editor#abort}. Committing is atomic: a read observes the full set
* of values as they were before or after the commit, but never a mix of values.
*
* <p>Clients call {@link #get} to read a snapshot of an entry. The read will
* observe the value at the time that {@link #get} was called. Updates and
* removals after the call do not impact ongoing reads.
*
* <p>This class is tolerant of some I/O errors. If files are missing from the
* filesystem, the corresponding entries will be dropped from the cache. If
* an error occurs while writing a cache value, the edit will fail silently.
* Callers should handle other problems by catching {@code IOException} and
* responding appropriately.

* libcore.io.DiskLruCache
* 1
* 100

* CLEAN 3400330d1dfc7f3f7f4b8d4d803dfcf6 832 21054
* DIRTY 335c4c6028171cfddfbaae1a9c313c52
* CLEAN 335c4c6028171cfddfbaae1a9c313c52 3934 2342
* REMOVE 335c4c6028171cfddfbaae1a9c313c52
* DIRTY 1ab96a171faeeee38496d8b330771a7a
* CLEAN 1ab96a171faeeee38496d8b330771a7a 1600 234
* READ 335c4c6028171cfddfbaae1a9c313c52
* READ 3400330d1dfc7f3f7f4b8d4d803dfcf6
*
* The first five lines of the journal form its header. They are the
* constant string "libcore.io.DiskLruCache", the disk cache's version,
* the application's version, the value count, and a blank line.
*
* Each of the subsequent lines in the file is a record of the state of a
* cache entry. Each line contains space-separated values: a state, a key,
* and optional state-specific values.
* o DIRTY lines track that an entry is actively being created or updated.
* Every successful DIRTY action should be followed by a CLEAN or REMOVE
* action. DIRTY lines without a matching CLEAN or REMOVE indicate that
* temporary files may need to be deleted.
* o CLEAN lines track a cache entry that has been successfully published
* and may be read. A publish line is followed by the lengths of each of
* its values.
* o READ lines track accesses for LRU.
* o REMOVE lines track entries that have been deleted.
*
* The journal file is appended to as cache operations occur. The journal may
* occasionally be compacted by dropping redundant lines. A temporary file named
* "journal.tmp" will be used during compaction; that file should be deleted if
* it exists when the cache is opened.

* What this class provides:
* 1. Helpers for reading & writing to URLs.
* - E.g. handles assets, resources, content providers, files, data URIs, http[s]
* - E.g. Can be used to query for mime-type & content length.
*
* 2. To allow plugins to redirect URLs (via remapUrl).
* - All plugins should call remapUrl() on URLs they receive from JS *before*
* passing the URL onto other utility functions in this class.
* - For an example usage of this, refer to the org.apache.cordova.file plugin.
*
* 3. It exposes a way to use the OkHttp library that ships with Cordova.
* - Through createHttpConnection().
*
* Future Work:
* - Consider using a Cursor to query content URLs for their size (like the file plugin does).
* - Allow plugins to remapUri to "cdv-plugin://plugin-name/$ID", which CordovaResourceApi
* would then delegate to pluginManager.getPlugin(plugin-name).openForRead($ID)
* - Currently, plugins *can* do this by remapping to a data: URL, but it's inefficient
* for large payloads.
