я занимаюсь проектами API и микросервисов - проект Exercise Tracker во freecodecamp
Я создал мини-проект, который отлично работает в моем регионе, поэтому я разместил его на glitch.com
в который сталкивается с какой-то ошибкой проекта ссылка , пожалуйста, помогите мне решить этот
сервер. js
const express = require("express");
const app = express();
const bodyParser = require("body-parser");
const cors = require("cors");
const { newUser, addExercise, showLogs } = require("./api/index.js");
const mongoose = require("mongoose");
mongoose.connect(process.env.MLAB_URI || "mongodb://localhost/exercise-track");
app.use(cors());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());
app.use(express.static("public"));
app.get("/", (req, res) => {
res.sendFile(__dirname + "/views/index.html");
});
app.post("/exercise/new-user", (req, res) => newUser(req, res));
app.post("/exercise/add", (req, res) => addExercise(req, res));
app.get("/exercise/log", (req, res) => showLogs(req, res));
// Not found middleware
app.use((req, res, next) => {
return next({ status: 404, message: "not found" });
});
// Error Handling middleware
app.use((err, req, res, next) => {
let errCode, errMessage;
if (err.errors) {
// mongoose validation error
errCode = 400; // bad request
const keys = Object.keys(err.errors);
// report the first validation error
errMessage = err.errors[keys[0]].message;
} else {
// generic or custom error
errCode = err.status || 500;
errMessage = err.message || "Internal Server Error";
}
res
.status(errCode)
.type("txt")
.send(errMessage);
});
const listener = app.listen(process.env.PORT || 3000, () => {
console.log("Your app is listening on port " + listener.address().port);
});
