I haven't got very far into it yet, but there's a number of plugins which can nudge neovim towards IDE functionality.

The language server protocol understands the syntax of your language. There are also plugins for autocompletion, and a file tree for fast navigation.

Caveat - long term vim user just starting to dabble into this territory. Have got started with Telescope for fuzzy file search, and Nerdtree for file navigation.
