Nodemon keeps restarting server

Question

I have an express server that uses a local json file for a database. I'm using https://github.com/typicode/lowdb for getters and setters.

Currently the server keeps starting and restarting without any problems, but can't access it. Below is my Server.js file:

import express from 'express'
import session from 'express-session'
import bodyParser from 'body-parser'
import promisify from 'es6-promisify'
import cors from 'cors'
import low from 'lowdb'
import fileAsync from 'lowdb/lib/storages/file-async'

import defaultdb from './models/Pages'

import routes from './routes/index.js'

const app = express();

const db = low('./core/db/index.json', { storage: fileAsync })

app.use(cors())

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.use('/', routes);

app.set('port', process.env.PORT || 1337);

db.defaults(defaultdb).write().then(() => {
    const server = app.listen(app.get('port'), () => {
      console.log(`Express running → PORT ${server.address().port}`);
    });
});

Anyone have an issue like this before? I think it has something to do with this line:

db.defaults(defaultdb).write().then(() => {
    const server = app.listen(app.get('port'), () => {
      console.log(`Express running → PORT ${server.address().port}`);
    });
});

Answer 1

From the documentation:

nodemon will watch the files in the directory in which nodemon was started, and if any files change, nodemon will automatically restart your node application.

If your db's .JSON file is under the watch of nodemon, and you're constantly writing to it, your server will restart in an infinite loop thus making it inaccessible. Try moving your .JSON file outside the scope of nodemon's watch via moving it outside your directory or via some nodemon configuration (if possible).

I solved this issue from this page.

practically you just have to do

 nodemon --ignore 'logs/*'
