What is ts-expand-hover.nvim?

This Lua plugin for Neovim lets you progressively expand TypeScript types inside hover floats, starting collapsed and drilling down level by level with + and -. It solves the pain of opaque type aliases in standard LSP hovers by leveraging TypeScript 5.9's verbosity controls via vtsls, showing syntax-highlighted code, JSDoc, and docs without closing the float.

Why is it gaining traction?

Unlike basic hover.nvim setups, it updates floats in-place for seamless expand/collapse, adds Treesitter highlighting inside TypeScript fences, and renders param/returns examples—making type inspection feel progressively expanding and interactive. Configurable keymaps avoid conflicts, plus health checks and fallbacks to vim.lsp.buf.hover keep it reliable. Developers dig the footer showing depth and actions, turning hovers into explorable type maps.

Who should use this?

Neovim users heavy into TypeScript or TSX files with vtsls, like frontend devs debugging complex generics or fullstack folks tracing API types. Skip if you're on older TypeScript or prefer VS Code's type peeks—it's tailored for buffer-local K hovers in large TS projects.

Verdict

Worth adding if you hit Neovim 0.10+, vtsls, and TS 5.9—solid docs, tests, and polish punch above its 17 stars and 1.0% credibility score. Still early; test in a side config before mainlining.
