This laravel 9 tutorial help to create CRUD rest endpoint using Elastic Search. We'll create a rest API for add a record, edit a record , list all records and delete a records from ES database. Nowadays, web application/tools are created on two layers, one is UI - which are created on front-end technology react, angular etc and the other is back-end which is created on backend technology like nodejs, PHP, java etc. I have created the front-end into reactjs and the backend API is created into Laravel 9. ElasticSearch is used as a database for this project. You can create a front-end into any technology as per your project requirements. I have already shared tutorials How To Integrate ElasticSearch With Laravel 9. I am extending this tutorial and adding CRUD operation using rest api. Laravel CRUD API Using ElasticSearch Let’s create a CRUD laravel API that will handle insert, update and delete elasticsearch operation. I have created ESController.php and EsService.php - This file will have all service methods that will communicate with ElasticSearch. Open api.php file and added below entry for CRUD Operation - //all elasticsearch data Route::get('es/all', 'ESController@getAllData'); // get single data Route::get('es/{id}', 'ESController@getDataById'); //create a record Route::post('es/create', 'ESController@insertData'); //upadte a record Route::put('es/update/{id}', 'ESController@updateData'); delete a record Route::delete('es/{id}', 'ESController@deleteData'); I have created all rest endpoints. How To Get All Record From Elastic Search Let's open ESController.php file and added getAllData() method to get all record. public function getAllData(Request $request) { $from 0; $size 200; $response $this->es_service->all($from, $size); return $this->jsonpSuccess($response); } We have passed constant from and size parameter to a service method, I have created all() method into EsService.php file. public function all($from 0, $size 200) { $es $this->es; $params $this->index; $params $this->type; $params $size; $params $from; try { $results $es->search($params); $hits $results; return $hits; } catch (\Exception $ex) { \Log::critical($ex); $this->apiError("ES - Unable to get Entries", 400); } } How To Create A Record Into ElasticSearch Using Laravel We'll create a method into the Controller file to insert a new record into the ES database. I already added an entry into api.php file which is using POST HTTP request, we ll pass the required data into post payload. Added below method into the ESController.php file - public function insertData(Request $request) { $parameters $request->json()->all(); if(isset($parameters) && $parameters ! '') { $response $this->es_service->create($parameters); return $this->jsonpSuccess($response); } else { return $this->jsonpError('Validation error(s) occurred', 400, 400, 'Data is not inserted!.'); } } We have gotten all posted payloads data using $request->json()->all() method and send to the service create() method. Now added create() method into the service file. public function create($input, $id null) { $es $this->es; $params $this->index; $params $this->type; $params $input; try { $result $es->index($params); return array("id" > $result); } catch (\Exception $ex) { \Log::critical($ex); return $this->apiError('ES - Unable to Create Entry', 400); } } Update A Record Into ElasticSearch Using Laravel Let's update a record in the elasticsearch database. We'll create a method into the controller file that'll call the service method to update the record into the database. As per route entry, Created a PUT type HTTP request to update data, we will pass ES id into the rest endpoint and post data into the HTTP request body as a JSON format. Let's add the below method into the ESController.php file - public function updateData($id, Request $request) { $data $request->json()->all(); if(isset($id) && $id ! '') { $response $this->es_service->update($id, $data); return $this->jsonpSuccess($response); } else { return $this->jsonpError('Validation error(s) occurred', 400, 400, 'Pipeline request data is not updated!.'); } } This method takes $id- ES database id and payloads as parameter. We'll create update() method into service. public function update($id, $input) { $es $this->es; $params $this->index; $params $this->type; $params $id; $params $input; try { $retUpdate $es->update($params); return array("id" > $retUpdate); } catch (\Exception $ex) { \Log::critical($ex); return $this->apiError('ES - Unable to Update Entry', 400); } } We have gotten all posted payload data using $request->json()->all() method and send it to the service create() method. Now added update() method into the service file. Delete A Record from ElasticSearch Using Laravel Now, I will delete a record from the ElasticSearch database. We'll create a method into the controller file that'll call the service method to delete record from the database. Let's create a PUT type HTTP request to delete data, We will pass ES id into the rest endpoint. Let's add the below method into the ESController.php file - public function deleteData($id) { if(isset($id) && $id ! '') { $response $this->self_serve_cmdb->deleteById($id); return $this->jsonpSuccess($response); } else { return $this->jsonpError('Validation error(s) occurred', 400, 400, 'Pipeline request data is not deleted!.'); } } This method takes $id- ES database id and payloads as parameter. We will create update() method into service. /** * delete an entry by es * * @param string $id */ public function deleteById($id) { $es $this->es; $params $this->index; $params $this->type; $params $id; try { $retDelete $es->delete($params); return array("id" > $retDelete); } catch (\Exception $ex) { \Log::critical($ex); return $this->apiError('ES - Unable to Delete Entry', 400); } } I have ES id as a parameter for delete a record using delete() method. Conclusion We have learned ElasticSearch integration with laravel into first part of this tutorial, This tutorial helped to create CRUD operation for elastic-search using laravel 9. Created Rest API add a record, update a record and delete a record from elasticsearch using Laravel 9.
