如何从symfony项目制作'npm run build'

Question

我当前有一个Symfony项目，该项目使用电子邮件基础来创建响应式电子邮件。

Foundation Framework使用命令" NPM Run Build"来转换文件。我尝试使用流程类进行服务解析我的内容，但我必须使用它错误，因为它不会执行" npm run构建"。这是我的错误代码：

<?php
/**
 * Created by PhpStorm.
 * User: jeremie
 * Date: 28/12/17
 * Time: 16:59
 */
namespace AcmeOpen4XMLParserBundleServices;
use SymfonyComponentFilesystemFilesystem;
use SymfonyComponentProcessProcess;

/**
 * @todo : code this
 */
class FoundationParser
{
    protected $foundationLocation;
    protected $process;
    /**
     * FoundationParser constructor.
     * @param $foundationLocation
     */
    public function __construct($foundationLocation)
    {
        $this->foundationLocation = $foundationLocation;
        $this->process = new Process('npm run build', $this->foundationLocation);
    }
    /**
     * Run npm run build if needed
     */
    public function initFoundation()
    {
        //make sure that 'npm run build' is running and execute it if not
        if (!$this->process->isRunning()) {
            $this->process->start();
        }
    }
    public function saveFoundationContent($foundationContent, $filename)
    {
        //save the file in foundation/src/pages
        $fileSystem = new Filesystem();
        $fileLocation = $this->foundationLocation . '/src/pages/' . $filename;
        if (!$fileSystem->exists($fileLocation)) {
            $fileSystem->dumpFile($fileLocation, $foundationContent);
            $fileSystem->chmod($fileLocation, 0664);
        }
    }
    public function retrieveValidHtml($fileName)
    {
        $fileLocation = $this->foundationLocation . '/dist/' . $fileName;
        while (true) {
            try {
                $result = file_get_contents($fileLocation);
                if ($result !== false){
                    return $result;
                }
            } catch (Exception $e) {
            }
        }
    }
}

我这样使用我的服务：

$foundationParser = $this->container->get('open4xmlparser.foundationparser');
$foundationParser->initFoundation();
$foundationParser->saveFoundationContent($foundationContent, 'test.html');
$response = new Response($foundationParser->retrieveValidHtml('test.html'));
$response->headers->set('Content-Type', 'text/html');
$response->send();

它告诉我" test.html"不存在。关于如何做我想做什么？

我最终决定做的是Symfony命令，该命令在无限循环中启动我的程序(永远不应该停止(。而不是使用服务，而是直接在While循环中执行了" NPM Run Build"。

protected function execute(InputInterface $input, OutputInterface $output)
{
    $output->writeln([
        '',
        'Running program',
        '===============',
        ''
    ]);
    $runBuild = new Process('npm run build', $this->getContainer()->getParameter('foundation_location'));
    while (true) {
        if (!$runBuild->isRunning()){
            $output->writeln([
                '',
                'Executing npm run build',
                ''
            ]);
            $runBuild->start();
        }
    }
}

目标文件中的saveFoundationContent和retrieveValidHtml中似乎有不同的路径。

// saveFoundationContent()
$fileLocation = $this->foundationLocation . '/src/pages/' . $filename;
// retrieveValidHtml()
$fileLocation = $this->foundationLocation . '/dist/' . $fileName;

显然， retrieveValidHtml()无法在位置中找到文件。

提示：将子目录路径存储为类变量(或常数(：

class FoundationParser
{
    private $subdir = "/dist/"; // or "/src/pages/";
    … 
    public function retrieveValidHtml($fileName)
    {
        $fileLocation = sprintf("%s%s%s", $this->foundationLocation, $this->subdir, $fileName);
        …
    }
}
