Heroku Node.js код ошибки H10 «Сбой приложения»

#javascript #node.js #heroku #deployment #crash

#javascript #node.js #heroku #развертывание #сбой

Вопрос:

Я только начал изучать NodeJS и попытался развернуть его в heroku. Когда я пытаюсь использовать «heroku open», произошел этот журнал.

Я искал решения в Интернете и пробовал эти решения:

  • перезапуск heroku
  • используйте process.env.PORT
  • npm очищает кэш
  • проверено, что я нахожусь в главной ветке
  • добавлен движок с правильной версией
  • Используйте «scripts»: { «start»: «узел index.js » }

Похоже, ни один из них не работает. Вот мой package.json:

и вот мой index.js:

 const http = require("http");
const path = require("path");
const fs = require("fs");
const nodemon = require("nodemon");

const server = http.createServer((req, res) => {

  // Build file path
  let filePath = path.join(
    __dirname,
    "public",
    req.url === "/" ? "index.html" : req.url
  );

  // Get extension of the file
  let extname = path.extname(filePath);

  // Initial content type
  let contentType = "text/html";

  // Check ext and set content type
  switch (extname) {
    case ".js":

  }

  fs.readFile(filePath, (err, content) => {
    if (err) {
      // Page not found error
      if (err.code == "ENOENT") {
        fs.readFile(
          path.join(__dirname, "public", "404.html"),
          (err, content) => {
            res.writeHead(200, { "Content-Type": "text/html" });
            res.end(content, "utf8");
          }
        );
      } else {
        // Other server error
        res.writeHead(500);
        res.end(`Server Error: ${err.code}`);
      }
    } else {
      // Success
      res.writeHead(200, { "Content-Type": contentType });
      res.end(content, "utf8");
    }
  });
});

//Check if environment variable exists and if not set 5000 as default
const port = process.env.PORT || 5000;

server.listen(port, () => {
  console.log("App is running on port "   port);
});

Ответ №1:

Я думаю, что проблема в const nodemon = require("nodemon"); строке. Просто удалите его.

Комментарии:

1. Вау не ожидал, что это будет решением. Он работал нормально, когда я использовал «запуск npm» или «запуск npm dev», почему он выдает ошибку на heroku?

2. Я думаю, что Heroku игнорирует зависимости разработчиков, поэтому, когда он сталкивается с этой строкой, он выходит из строя, потому что не может найти этот пакет.
