The Idea
OXID eSales would like to provide a lightweight reusable example module incorporating our best practices recommendations to be used as a template for developing own module solutions.
Story:
- Module will extend a block on shop start page to show a greeting message (visible when module is active).
- Module will have a setting to switch between generic greeting message for a logged in user and a personal custom greeting. The Admin's choice which way it will be.
- A logged in user will be able to set a custom greeting depending on module setting. Press the button on start page and be redirected to a module controller which handles the input.
- User custom greetings are saved via shop model save method. We subscribe to BeforeModelUpdate to track how often a user changed his personal greeting.
- Tracking of this information will be done in a new database table to serve as an example for module's own shop model.
- Module will extend the shop's basket model to add info to module specific log file when an item is added into basket. Logging can be enabled or disabled depending on module setting.
- Module will have console command
oetemplate:logger:read
to read log file.
./vendor/bin/oe-console oetemplate:logger:read
Goals
There are three main goals this repository is intended to help with:
- Install and try out the module with simple examples to most common development questions.
- The provided solution can be used as a base for your own module. It will help creating the personalized module base with all the examples listed in the Examples section.
- The repository can be used for creating a clean skeleton with only preconfigured OXID recommended quality tools for your new module.
Please jump to the section that fits your needs.
Examples
The repository contains examples of following cases and more:
-
Extending of shop controllers and models
- extending a shop model (
OxidEsales\ModuleTemplate\Extension\Model\User
) / (OxidEsales\ModuleTemplate\Extension\Model\Basket
) - extending a shop controller (
OxidEsales\ModuleTemplate\Extension\Controller\StartController
)
- extending a shop model (
-
- own module controller (
oemtgreeting
with own template and own translations) - own module admin controller (
oemt_admin_greeting
with own template and own translations)
- own module controller (
-
- extending a shop database table (
oxuser
)
- extending a shop database table (
-
Accessing the database
- model with a database (
OxidEsales\ModuleTemplate\Tracker\Model\GreetingTracker
) oxNew
object factory example (OxidEsales\ModuleTemplate\Greeting\Infrastructure\UserModelFactory
)- DAO
- model with a database (
-
Templates
- creating templates for your module
- extending of oxid theme templates or blocks
- extending a shop admin template block (
admin_user_main_form
- only an extension of a block, without functionality) - extending a shop template block (
start_newest_articles
)
- extending a shop admin template block (
-
Using the translations for your module specific phrases
-
Events and listeners
-
Testing your module backend and frontend part
HINTS:
- Only extend the shop core if there is no other way like listen and handle shop events, decorate/replace some DI service.
- Your module might be one of many in the class chain and you should act accordingly (always ensure to call the parent method and return the result).
- When extending shop classes with additional methods, best prefix those methods in order to not end up with another module picking the same method name and wreacking havoc.
- In case there is no other way than to extend existing shop methods try the minimal invasion principle. Put module business logic to a service (which make it easier to test as well) and call the service in the extended shop class. If you need to extend the shop class chain by overwriting, try to stick to the public methods.
Not yet in here but might come later:
- example for payment gateway extension
- seo url for module controller
- to redirect or not to redirect from inside the shop core
- graphql query/mutation example
- extending the internal part
Install and try it out
Note: This installation method fits for trying out the module development basics, its not meant to be used as development base for your own module. Check further installation/usage methods.
This module is in working state and can be directly installed via composer:
composer require oxid-esales/module-template
./vendor/bin/oe-eshop-doctrine_migration migrations:migrate oe_moduletemplate
and activate the module.
Use as a base for own module
In case you'd like to use this module as a template for your own module, this section is for you.
Important Instructions here are for the case you intend to develop a module for OXID eShop 7.2.x. For other versions, refer to the version specific branch.
Before starting to do something, please, read the whole section once, then decide on required questions, decide what you want to achieve, and follow the procedure.
Terms
First, lets decide on terms:
- Module is installable to
vendor/<yourPackageName>
directory. The package name is lowercased and looks like:<yourVendorName>/<yourModuleName>
, example:oxid-esales/module-template
. Decide what will be your new module package name.- Please note that combination of
<yourVendorName>
and<yourModuleRootDirectory>
should be unique. Based on this information your module id will be composed and will look like:<yourVendorPrefix>_<yourModuleRootDirectory>
. In our case it isoe_moduletemplate
. - It is recommended to use only alphanumeric characters, in case you need a separator you can use dash ("-") or underscore("_").
- Please note that combination of
- Decide on your module's namespace -
<YourVendorName>\<YourModuleName>
, example:OxidEsales\ModuleTemplate
. - Decide on your module's ID -
<YourVendorPrefix>_<yourModuleName alphanumeric part>
, example:oe_moduletemplate
.- It is recommended to use only alphanumeric characters, in case you need a separator you can use underscore. More information about module id can be found here.
In the following examples, your information required places will be shown as placeholders: <yourPackageName>
, it means
you should put your package name at that place, without brackets, for example:
composer config repositories.<yourPackageName> path source/modules/<yourVendorName>/<yourModuleName>
will possibly look like:
composer config repositories.my-vendor-name/my-module-name path source/modules/mvn/mymodulerootdir
in our case it is:
composer config repositories.oxid-esales/module-template path source/modules/oe/module-template
Procedure
The following procedure describes how to create a base for your further module, and shows the basic installation for the development process:
1. Use the Template
Click on the "Use this template" button on the template main page to create your module repository from the given template.
Please make sure to NOT choose the 'take all branches' option, as this will clone the repository with everything we have in our repository. Having all branches also will trigger the github actions for all branches and you dont want this usually.
As an outcome of this step, you should have a repository with one "Initial commit" of our current latest repository state.
2. Personalize and cleanup the module
To personalize the module, use the "bin/personalize.sh" script. This script will prompt you for required information and do the work.
To cleanup the module from all current examples and make it a clean skeleton, use the "bin/cleanexamples.sh" script. This script will remove all example solutions code.
Its not mandatory to cleanup the module from examples, but you have this option if you want to start from the clean skeleton.
For this step, clone your module repository anywhere to your local directory and run the desired scripts.
git clone <yourGitRepositoryUrl> myModule cd myModule // Run the personalize script ./bin/personalize.sh // Run the clean examples script if you want to start from the clean skeleton ./bin/cleanexamples.sh git commit -am "Personalize and cleanup the module" git push origin
Please note that the module comes with a database table, translations, settings and some templates which still have the original names after personalization, if cleanup was not done. Just keep an eye on all that's prefixed 'OEMT', 'oemt', 'OEMODULETEMPLATE' etc.
Also, you will need to adjust the README, CHANGELOG, LICENSE, metadata and the GitHub workflow file, with your credentials and names. For running SonarCloud as part of the steps in GitHub workflow you will need to configure SonarCloud and to create a secret environment variable for your repository called SONAR_TOKEN. The token itself is provided by SonarCloud.
3. Install the module for Development
For installing the module for development our recommended way, check the "Development installation section", or do it any other way you prefer, but make sure to reconfigure our preconfigured quality tools to fit your installation.
Development installation
We recommend developing the module as independent as possible. This means that the module for development should be installed as a root package, with its own strict dependencies if such are needed.
Consider using our docker based SDK and our "Recipes" to install this module development variant. Make sure you have all your current docker containers stopped before starting on this.
cd ~/Projects echo ModuleTemplate && git clone https://github.com/OXID-eSales/docker-eshop-sdk.git $_ && cd $_ git clone --recurse-submodules https://github.com/OXID-eSales/docker-eshop-sdk-recipes recipes/oxid-esales // Important: In case you want to develop your module created from module template, edit the recipe with your // module repository and module id first ./recipes/oxid-esales/module-template/b-7.2.x-root.sh -eCE
Things to be aware of
The module template is intended to act as a tutorial module so keep your eyes open for comments in the code.
NOTES:
- Acceptance tests are way easier to write if you put an id on relevant fields and buttons in the templates.
- If you can, try to develop on OXID eShop Enterprise Edition to get shop aware stuff right from the start.
Module migrations
- migrations are intended to bump the database (and eventual existing data) to a new module version (this also goes for first time installation).
- ensure migrations are stable against rerun
Migrations have to be run via console command (./vendor/bin/oe-eshop-doctrine_migration
)
./vendor/bin/oe-eshop-doctrine_migration migrations:migrate oe_moduletemplate
NOTE: Existing migrations must not be changed. If the database needs a change, add a new migration file and change to your needs:
./vendor/bin/oe-eshop-doctrine_migration migrations:generate oe_moduletemplate
For more information, check the developer documentation.
Where the module namespace points to
As already mentioned above, in the 7.x versions of OXID eShop, the module code only resides in the vendor directory so the namespace needs to point there. In our case this looks like
"autoload": { "psr-4": { "OxidEsales\\ModuleTemplate\\": "src/", "OxidEsales\\ModuleTemplate\\Tests\\": "tests/" } },
Running tests and quality tools
Check the scripts
section in the composer.json of the module to get more insight of
preconfigured quality tools available. Example:
$ composer phpcs $ composer phpstan $ composer phpmd
Integration/Acceptance tests
- install this module into a running OXID eShop
- run
composer update
in module root directory
$ cd vendor/oxid-esales/module-template
$ composer update
After this done, check the "scripts" section of module composer.json
file to see how we run tests.
$ composer tests-unit $ composer tests-integration $ composer tests-codeception
NOTE: From OXID eShop 7.0.x on database reset needs to be done with this command (please fill in your credentials)
$ bin/oe-console oe:database:reset --db-host=mysql --db-port=3306 --db-name=example --db-user=root --db-password=root --force
And just in case you need it, admin user can now also be created via commandline
$ bin/oe-console oe:admin:create-user --admin-email <admin-email> --admin-passowrd <admin-password>
for example
$ bin/oe-console oe:admin:create-user --admin-email admin@oxid-esales.com --admin-password admin
Writing Codeception tests
As a rule of thumb, use codeception tests to ensure the frontend is behaving as expected. Codeception tests take a while to run, so try to navigate the way between covering the relevant cases and overtesting.
We definitely need some acceptance tests if the module affects the frontend like in our example. If the module breaks the frontend, we need to see it asap.
In our case, we cover the reaction of the startpage to the different possibilities
- generic greeting mode (with/without logged in user)
- personal greeting mode (with/without logged in user)
- updating the greeting mode
- ensure module can be activated/deactivated without destroying the shop
- ensure edge case safety like not logged in user directly calling module controller
The great thing about codeception tests is - they can create screenshot and html
output in failure case, so you literally get a picture of the fail (tests/Coreception/_output/
).
Development Environment - Docker SDK
You can install the shop on whatever system fits your needs, but please check the OXID Docker SDK recipes. That's what we use in OXID Development to quickly set up whatever development environment we need and we are constantly trying to improve them.
Github Actions Workflow
The module template comes complete with a github actions workflow. No need to rig up some separate continuous integration
infrastructure to run tests, it's all there in github.
You will see three files in .github/workflow
directory. The workflow from
.github/workflow/trigger.yaml
starts on every push
and pull_request
to run the code quality checks and all the module tests.
In our experience it is useful to run the shop tests with the module installed and activated from time to time. For sure those shop tests have been written with only the shop itself in mind. Your module, depending on what it is doing, might completely change the shop behaviour. Which means those shop tests with a module might just explode in your face. Which is totally fine, as long as you can always explain WHY those tests are failing.
Real life example: There is one shop acceptance test case OxidEsales\EshopCommunity\Tests\Acceptance\Frontend\ShopSetUpTest:
which is testing the frontend shop setup. Very good chance this test will fail if a module is around which extends
the class chain. That test is for setting up a shop from scratch so it will simply not expect a module to be around.
And we only need our module to safely work with a working shop. We definitely will decide to skip that ShopSetUpTest
as we have a good explanation as to why it will not work. And having this special test case work with our module will give no benefit.
This is only one example, there might be other tests that fail with your module but fail because your module is changing the shop. In that case the suggestion would be to exclude the original test from the github actions run, copy that test case to your module tests and update to work with your module. This was for example the strategy used for our reverse proxy modules which are mandatory to not make the shop's acceptance tests fail. Unless those test cases that somehow bypass reverse proxy cache invalidation. To be on the safe side, we took over those few test cases to the module and plan to improve the shop tests as soon as possible. We'll gladly also take your PR with improved shop tests ;)
And then there are some few shop tests marked as @group quarantine
in the doc block. Test in that group have stability issues so they'd better
be excluded as well.
Ps: a failing shop test might also turn up issues in your module, in that case fix the module and let the test live ;)
