Question 1

How do I set up denops shared server to speed up plugins?

Accepted Answer

Install the denops-shared-server.vim plugin, call denops_shared_server#install() in Vim, and set g:denops_server_addr in your .vimrc. This reuses a Deno process to reduce startup delays, as detailed in the README's shared server section.

Question 2

Denops or coc.nvim: which should I choose for JavaScript plugins?

Accepted Answer

Denops uses Deno for a modern, type-safe approach with better security, while coc.nvim relies on Node.js with a larger ecosystem. Choose Denops for Deno integration and cross-editor support, but coc.nvim if you need more pre-existing plugins and Node.js compatibility.

Question 3

Why is denops slow on Windows and how to fix it?

Accepted Answer

Slowdowns on Windows often occur because antivirus software scans Deno's cache directory. Exclude this directory from scans using Windows Security settings, as advised in the README, to improve performance.

Question 4

What versions of Vim and Neovim are supported by denops?

Accepted Answer

Denops supports Vim 9.1.1646 or above, based on Homebrew and vim-win32-installer versions, and Neovim 0.11.3 or above, following a policy of supporting the two most recent minor versions for Neovim and Deno.

Question 5

How to write a simple denops plugin in TypeScript?

Accepted Answer

Refer to the Denops Documentation for guides, or study example plugins like denops-helloworld.vim. Use Deno to run TypeScript code, leveraging denops.vim's APIs to interact with Vim/Neovim, with type safety from TypeScript.

Question 6

Can I use denops with existing Vimscript plugins?

Accepted Answer

Yes, denops plugins can coexist with Vimscript plugins, as denops.vim acts as a bridge. However, integration might require careful handling of asynchronous calls and event handling, since denops uses Deno processes separate from Vim's runtime.
