README

Bundle makes it easier to optimize backend's loading speed for up to 50%, it does it in several ways:

• Provides console commands which can generate shell scripts which can be used to compile all bundle's extjs classes together using Sencha Cmd. Using these scripts you will use Sencha Cmd without the need to learn how to use and configure it, it will be done for you behind the scene. NB! Generated scripts rely on Docker!
• Ships a special resources-loader which makes it possible to automatically detect and include MJR.js and a javascript file which is compiled from bundles' javascript extjs-classes (with default configuration it is named bundles.js).
• Using a semantic configuration makes it possible to mark certain bundles (using regex-like syntax) and their javascript files as non-blocking resources. This is especially useful when there're bundles whose assets are not designated as non-blocking but in fact they are and you want to override this behaviour, make them load asynchronously.

Installation

Add this dependency to your composer.json:

"modera/backend-on-steroids-bundle": "~1.0"

Update your AppKernel class and add ModeraBackendOnSteroidsBundle declaration there:

new Modera\BackendOnSteroidsBundle\ModeraBackendOnSteroidsBundle()

Documentation

Once you have installed the bundle please use modera:backend-on-steroids:generate-scripts command, once executed it will generated four shell scripts for you:

• steroids-setup.sh - This script will prepare an extjs workspace for you that will be used to compile your assets using Sencha Cmd
• steroids-compile-bundles.sh - Once you have steroids set up and your extjs classes copied (use modera:backend-on-steroids:copy-classes-to-workspace for that) you can invoke this command and have all your installation extjs classes will be compiled together, the result, if no configuration changed, will copied to web/backend-on-steroids/bundles.js file.
• steroids-compile-mjr.sh - compiles MJR for you and places it, if no semantic configuration is modified, to web/backend-on-steroids/MJR.js
• steroids-cleanup.sh - If you don't anymore need extjs-workspace then you can use this script and it will delete all developers files that were created to setup extjs-workspace (your compiled extjs classes won't be touched)

See Modera\BackendOnSteroidsBundle\DependencyInjection\Configuration for a full list of available configuration properties.

In order to make your extjs classes visible to modera:backend-on-steroids:copy-classes-to-workspace, you need to contribute to modera_backend_on_steroids.extjs_classes_paths extension-point or if you are not going to distribute your bundles you can use modera_backend_on_steroids/compiler/path_patterns configuration property.

Typical workflow

1. $ app/console modera:backend-on-steroids:generate-scripts
2. Make generated scripts executable (when modera:backend-on-steroids:generate-scripts is executed required shell command is printed that you can use)
3. $ ./steroids-setup.sh
4. $ app/console modera:backend-on-steroids:copy-classes-to-workspace
5. $ ./steroids-compile-bundles.sh
6. $ ./steroids-compile-mjr.sh

Once this steps are completed, given that you haven't changed this bundle's semantic configuration compiler/path_patterns property), when you refresh backend you should see that MJR.js and bundles.js are automatically included using "script" tags. Script steroids-setup.sh you need to execute only once per foundation installation or after you have used steroids-cleanup.sh.

Troubleshooting

Sencha Cmd not finding classes

If, while executing ./steroids-compile-bundles.sh you are getting BUILD FAILED similar to this one:

[ERR] BUILD FAILED
[ERR] com.sencha.exceptions.ExBuild: Failed to find any files for /var/www/packages/bundles/src/MyCompany/mypackage/CustomerHistory.js::ClassRequire::MyCompany.mypackage.CustomerHistoryActivity
[ERR]
[ERR] Total time: 21 seconds
[ERR] The following error occurred while executing this line:
/var/www/packages/bundles/.sencha/package/build-impl.xml:137: The following error occurred while executing this line:
/var/www/packages/bundles/.sencha/package/js-impl.xml:32: com.sencha.exceptions.ExBuild: Failed to find any files for
/var/www/packages/bundles/src/MyCompany/mypackage/CustomerHistory.js::ClassRequire::MyCompany.mypackage.CustomerHistoryActivity

It means that your file, which in this case is located at /var/www/packages/bundles/src/MyCompany/mypackage/CustomerHistory.js is referencing a class MyCompany.mypackage.CustomerHistoryActivity which Sencha Cmd compiler cannot find. This usually means one of two things:

• modera:backend-on-steroids:copy-classes-to-workspace command didn't find a directory where MyCompany.mypackage.CustomerHistoryActivity is located and therefore could not properly prepare steroids' workspace. To solve this problem you need to find where CustomerHistoryActivity.js file is located and update modera_backend_on_steroids/path_patterns configuration property. For more details please see \Modera\BackendOnSteroidsBundle\DependencyInjection\Configuration. Once configuration property is updated, don't forget to run modera:backend-on-steroids:copy-classes-to-workspace again. If you checked your project and still couldn't find CustomerHistoryActivity.js file anywhere, chances are that you are dealing with the second case:
• CustomerHistoryActivity class has been deleted, but developer simply forgot to update CustomerHistory class to remove CustomerHistoryActivity from its dependencies. In this case what you need to do is to open CustomerHistory.js file, locate its requires or similar dependency declaration block and remove CustomerHistoryActivity from there. Once its done you can run modera:backend-on-steroids:copy-classes-to-workspace and then ./steroids-compile-bundles.sh.
