Atom exclude node_modules folder from search

Steps

1. Launch atom
2. From the menu: edit > preferences (atom > prefernces on Mac)
3. From the side menu, click the button “Open Config Folder”

Now a new atom IDE should open.

1. Open the file “config.cson”
2. Add ignoredNames: ["node_modules"] under core

Example of a config.cson

"*":
  core:
    ignoredNames: [
      ".git"
      "node_modules"
    ]
  editor: {}
  minimap:
    plugins:
      "highlight-selected": true
      "highlight-selectedDecorationsZIndex": 0
  welcome:
    showOnStartup: false

Hope this helps
