Question 1

How to ignore node_modules in Nodemon?

Accepted Answer

By default, Nodemon ignores node_modules, but you can explicitly set it using `--ignore 'node_modules'` or in `nodemon.json` with `"ignore": ["node_modules"]`. This prevents unnecessary restarts from dependency changes.

Question 2

Nodemon not restarting in Docker – how to fix?

Accepted Answer

This is common due to file system event issues in containers. Use the `--legacy-watch` or `-L` flag to enable polling mode, which handles mounted volumes, as mentioned in the README under 'Application isn't restarting.'

Question 3

How to delay Nodemon restart after file changes?

Accepted Answer

Use the `--delay` flag followed by seconds or milliseconds, e.g., `nodemon --delay 2.5 server.js`. This adds a throttle to prevent multiple restarts during rapid file saves, with config options shown in the README.

Question 4

Nodemon vs PM2 for development – which is better?

Accepted Answer

Nodemon is focused on development with automatic restarts on file changes, while PM2 is geared towards production process management and clustering. For local development, Nodemon's simplicity and restart automation make it the preferred choice.

Question 5

Can Nodemon run and monitor Python scripts?

Accepted Answer

Yes, use the `--exec` flag to specify the Python executable, e.g., `nodemon --exec "python" app.py`. You can also set up default executables in `nodemon.json` using `execMap` for languages like Perl or Ruby.

Question 6

How to configure Nodemon to watch only specific file extensions?

Accepted Answer

Use the `-e` or `--ext` switch followed by a comma-separated list, like `nodemon -e js,ts`. This restricts monitoring to files with those extensions, as explained in the 'Specifying extension watch list' section.
