In order to use this **PHP** client you must have installed the **GEPARD** middleware. This is simply done by executing the command: ``` npm install gepard ``` Prerequisite for this command is the installation of node and npm. For more information see [gepard on npm](https://www.npmjs.com/package/gepard) and [gessinger-hj/gepard on github](https://github.com/gessinger-hj/gepard). If you are interested in the python client see [gepard-python on pypi](https://pypi.python.org/pypi/gepard-python)and [gepard-python on github](https://github.com/gessinger-hj/gepard-python) Install ======= [](#install) If you not yet have a composer.json create this file with the following content: ``` { "require": { "gepard/gepard-php": ">=1.0" }, "minimum-stability": "dev" } ``` If this composer.json file already exists in your project-directory add the body-lines above. After this is done execute the command: ``` composer install ``` Usecases ======== [](#usecases) Updating a Customer-record in the Database ------------------------------------------ [](#updating-a-customer-record-in-the-database) Suppose there is a database containing customer base-data like for example name, id, enabled,... The access to the database for example is done with **laravel/eloquent**. The UPDATE is coded with the following code-snippet: ``` $customer_Id = 1 ; $customer = App\Customer::find($customer_id); $customer->name = 'New Customer Name'; $customer->save(); ``` Interested 3rd parties now are informed by sending an Event: ``` Client::getInstance()->emit('CUSTOMER_CHANGED', ['CUSTOMER_ID' => $customer_id]); ``` Interested parties for example are: - A Java program which sends an e-mail. ``` Client.getInstance().on ( new String[] { "CUSTOMER_CHANGED" }, (e) -> { Integer customer_id = e.getValue ( "CUSTOMER_ID" ) ; *select customer from database with customer_id* *use any mail-api to send mail* } ) ; ``` - A JavaScript program which sends an e-mail: ``` gepard.getClient().on ( 'CUSTOMER_CHANGED', (e) => { let customer_id = e.getValue ( 'CUSTOMER_ID' ) ; *select customer from database with customer_id* *use any mail-api to send mail* } ) ; ``` - A Python program which sends an e-mail: ``` def on_CUSTOMER_CHANGED ( event ): customer_id = event.getValue ( 'CUSTOMER_ID' ) ; *select customer from database with customer_id* *use any mail-api to send mail* gepard.Client.getInstance().on ( 'CUSTOMER_CHANGED', on_CUSTOMER_CHANGED ) ; ``` - A single page web-app or a React-native app ``` gepard.getWebClient().on ( 'CUSTOMER_CHANGED', (e) => { let customer_id = e.getValue ( 'CUSTOMER_ID' ) ; if ( customer-data are displayed in any part of the page ) { *select customer from database with customer_id via a REST call* *update appropriate display* } } ) ; ``` ### Health Score 20 — LowBetter than 13% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity5 Limited adoption so far Community8 Small or concentrated contributor base Maturity41 Maturing project, gaining track record Bus Factor1 Top contributor holds 72% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
