Install

Make sure to have currently installed Docker:

docker --version

Install the application dependencies:

yarn install

Make sure if your code is able to be deployed:

yarn lint:fix && yarn format:fix

Build the production code:

yarn build

Build and up the current code to Docker:

docker-compose up --build

Execute

After building the source code you must be able to access the API requests, here's an example using CURL:

curl --request POST \
  --url http://localhost:3000/currency/conversion \
  --header 'Content-Type: application/json' \
  --data '{
	"from": "EUR",
	"to": "BRL",
	"amount": 2300
}'

To be implementend on Wordpress you can easily use some library as properly CURL:

<?php

$curl = curl_init();

curl_setopt_array($curl, [
  CURLOPT_PORT => "3000",
  CURLOPT_URL => "http://localhost:3000/currency/conversion",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => "{\n\t\"from\": \"EUR\",\n\t\"to\": \"BRL\",\n\t\"amount\": 2300\n}",
  CURLOPT_HTTPHEADER => [
    "Content-Type: application/json"
  ],
]);

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}

Or HTTP1:

<?php

$request = new HttpRequest();
$request->setUrl('http://localhost:3000/currency/conversion');
$request->setMethod(HTTP_METH_POST);

$request->setHeaders([
  'Content-Type' => 'application/json'
]);

$request->setBody('{
	"from": "EUR",
	"to": "BRL",
	"amount": 2300
}');

try {
  $response = $request->send();

  echo $response->getBody();
} catch (HttpException $ex) {
  echo $ex;
}
