nodemon ignore directory

In the very likely circumstance that you're using nodemon in a configuration file, you can create a separate configuration entry for those files to be ignored. Bonus, a cleaner looking nodemon call, especially if files to ignore grows large.

For example, this package.json instructs nodemon to ignore directory test:

{
  "scripts": {
    "test": "jest",
    "start": "nodemon server.js"
  },
  "nodemonConfig": {
      "ignore": ["test/*"]
  }
}

As in the other answer, be sure to restart nodemon for the configuration changes to take effect.

Create nodemon.json in your project root that looks something like this:

{
  "ignore": ["db.json"]
}

This is an alternative to using package.json as seen in Andrew Philips answer

See docs

You need to replace .. with ., or just reference client/ directly, also you will need to remove the asterisk:

"devStart": "nodemon --ignore ./client/ --exec babel-node src/server.js"

Or

"devStart": "nodemon --ignore client/ --exec babel-node src/server.js"

According to nodemon docs this is how to ignore a directory via command line:

nodemon --ignore lib/ --ignore tests/

Also note that nodemon will only restart the node process, if you change the npm script you will need to kill the process and re-run npm run devStart
