How do I open nvim-tree in startup without overiding the NvChad nvim-tree setup options.

[FosRexx]

I want to open nvim-tree in startup and following this and this, I made this lua file in .config/nvim/lua/plugins/nvim-tree.lua:

return {
  "nvim-tree/nvim-tree.lua",
  lazy = false,
  config = function ()
    require("nvim-tree").setup {}
    require("nvim-tree.api").tree.open()
  end
}

But doing that overrides the default "look"/"options" of nvim-tree, the one provided by NvChad. I am aware that this is caused by the line require("nvim-tree").setup {} but if I do not add that line then nvim-tree complains saying [NvimTree] nvim-tree setup not called and then nvim-tree wont open with error E492: Not an editor command: NvimTreeToggle.

And so I was just wondering if their is a way to open nvim-tree on startup while keeping the NvChad's setup.

@FosRexx you can run the open() in vim.schedule or vim.defer_fn

I am sorry but I am very new to NeoVim and so i dont know where to add that command as in which file do I add that command?

I added require("nvim-tree.api").tree.open() after require("mappings") inside the vim.schedule() function in .config/nvim/init.lua and that seems to have worked.

After learning more about neovim I did this quite differently than the original answer, I wont explain the reasons much here be I will just share what I have done.

First i added this line at the end of ~/.config/nvim/init.lua file:

require "custom"

Then I created a custom directory in ~/.config/nvim/lua/, now we have a directory like ~/.config/nvim/lua/custom/

Then I created a init.lua file inside ~/.config/nvim/lua/custom/. Now in ~/.config/nvim/lua/custom/init.lua, I added this line:

require("custom.nvimtree")

Now I again created a new file named nvimtree.lua inside ~/.config/nvim/lua/custom/. Now in ~/.config/nvim/lua/custom/nvimtree.lua, I added this which is copied directly from the nvim-tree wiki:

-- Open nvim-tree on startup
local function open_nvim_tree()
  -- open the tree
  require("nvim-tree.api").tree.open()
end

vim.api.nvim_create_autocmd({ "VimEnter" }, { callback = open_nvim_tree })

This setup works and nvim-tree opens on startup.
