format-ts-errors.nvim

A very simple Neovim plugin to explain your errors using AI.

Requirements

This plugin uses curl to call the Anthropic API.

You will also need an Anthropic API key.

Installation

Using Lazy.nvim:

{
    'z0rzi/format-ts-errors.nvim',
    config = function()
        require('format-ts-errors').setup({
            mappings = {
                show_diagnostic = "L", -- Show the diagnostic under the cursor
                show_AI_diagnostic = ";h", -- Asks Claude to explain the diagnostic under the cursor
                goto_next = ";j", -- Go to the next diagnostic
                goto_prev = ";k", -- Go to the previous diagnostic
            },

            anthropic_api_key = nil, -- You can also define it as an environment variable (ANTHROPIC_API_KEY)
        })

        -- Optional, to enable highlighting of the types (requires treesitter)
        vim.g.markdown_fenced_languages = { 'typescript' }
    end,
},

How it works

This plugin uses the Anthropic API to generate a comprehensive explanation of the error under the cursor. If you hit the show_AI_diagnostic keymap, multiple times in a row, you can ask follow-up questions to the AI.
