How to make Telescope ignore files inside node_modules?

Question

I'm new in the VIM / NEOVIM world so I probably am doing something else wrong, but from the docs it says that Telescope will ignore all the files registered in the .gitignore file, which is definitively there but it still searches in node_modules

So this is what I do:

1. I cd into my project folder
2. Hit nvim
3. hit <leader>ff
4. Telescope opens and I start typing, but searches are really slow because they are including node_modules

These are the plugins that I have for setting up telescope

" Telescope
Plug 'nvim:solua/popup.nvim'
Plug 'nvim-lua/plenary.nvim'
Plug 'nvim-telescope/telescope.nvim'

And then my remaps right from the docs:

" Find files using Telescope command-line sugar.
nnoremap <leader>ff <cmd>Telescope find_files<cr>
nnoremap <leader>fg <cmd>Telescope live_grep<cr>
nnoremap <leader>fb <cmd>Telescope buffers<cr>
nnoremap <leader>fh <cmd>Telescope help_tags<cr>

All this is running in a WSL terminal with Ubuntu. What am I missing?

Just add

require('telescope').setup{ 
  defaults = { 
    file_ignore_patterns = { 
      "node_modules" 
    }
  }
}

to your init.lua
