It's worth learning again what neovim offers with LSP and it's ecosystem.

You'd appreciate nothing out of Typescript if your editor doesn't do LSP.

AstroNvim gives you a good start.

Feels like they all try to make vscode out of vim. Is there a truly vim-spirited LSP plugin? The one that doesn’t flicker on its own when you type, and only shows issues in quickfix after :make equivalent, even if it works asynchronously (works with Vim would also be great). I don’t mind configuring it for a week, but what’s on gif-shots usually repels me.

Basically all you need is nvim-lspconfig, which just attaches the language servers to your buffers (so you wouldn't even need that, but it saves a lot of boilerplate). From there you can use all you already know (this is from my Lua-based config, but you can do the same in Viml):

    vim.keymap.set("n", "K", vim.lsp.buf.hover, { buffer = buf })
    vim.keymap.set("n", "<leader>qf", vim.diagnostic.setqflist, { buffer = buf, desc = "Quickfix diagnostics" }) -- open Quickfix with LSP issues, Loclist possible too
    vim.api.nvim_buf_set_option(buf, "omnifunc", "v:lua.vim.lsp.omnifunc") -- use LSP completion for omnifunc
    vim.api.nvim_buf_set_option(buf, "tagfunc", "v:lua.vim.lsp.tagfunc") -- Ctrl+] for go to definition using LSP instead of ctags
    vim.api.nvim_buf_set_option(buf, "formatexpr", "v:lua.vim.lsp.formatexpr()") -- Code formatting (gq etc) using LSP

Everything else one always sees with Neovim and LSP are other plugins like nvim-cmp or Telescope.

I've been using ALE for years and even contributed to it: https://github.com/dense-analysis/ale
