Describe the bug

Conform (I think) is having trouble discovering the prettier plugin included in the project. prettierd and prettier both try to find the plugin in noop.js

What is the severity of this bug?

tolerable (can work around it)

Steps To Reproduce

1. Create a TypeScript project using npm
2. Add prettier and prettier-plugin-tailwindcss
3. Add a .prettierrc to the project, with { "plugins": ["prettier-plugin-tailwindcss"] }
4. Configure conform for TypeScript: formatters_by_ft = { typescript = { 'prettierd', 'prettier', stop_after_first = true } }
5. Create a TypeScript file, add some content, and attempt to format the file.

Expected Behavior

conform discovers prettier plugins, and applies them.

Minimal example file

import { useState } from "react"
import reactLogo from "./assets/react.svg"
import viteLogo from "/vite.svg"
import "./App.css"

function App() {
  const [count, setCount] = useState(0)

  return (
    <>
    
      <div className="bg-black mx-2 rounded">
        <a href="https://vitejs.dev" target="_blank">
          <img src={viteLogo} className="logo" alt="Vite logo" />
        </a>
        <a href="https://react.dev" target="_blank">
          <img src={reactLogo} className="logo react" alt="React logo" />
        </a>
      </div>
      <h1>Vite + React</h1>
      <div className="card">
        <button onClick={() => setCount((count) => count + 1)}>
          count is {count}
        </button>
        <p>
          Edit <code>src/App.tsx</code> and save to test HMR
        </p>
      </div>
      <p className="read-the-docs">
        Click on the Vite and React logos to learn more
      </p>
    </>
  )
}

export default App

Minimal init.lua

-- DO NOT change the paths and don't remove the colorscheme
local root = vim.fn.fnamemodify("./.repro", ":p")

-- set stdpaths to use .repro
for _, name in ipairs({ "config", "data", "state", "cache" }) do
  vim.env[("XDG_%s_HOME"):format(name:upper())] = root .. "/" .. name
end

-- bootstrap lazy
local lazypath = root .. "/plugins/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "--single-branch",
    "https://github.com/folke/lazy.nvim.git",
    lazypath,
  })
end
vim.opt.runtimepath:prepend(lazypath)

-- install plugins
local plugins = {
  "folke/tokyonight.nvim",
  {
    "stevearc/conform.nvim",
    config = function()
      require("conform").setup({
        log_level = vim.log.levels.DEBUG,
        formatters_by_ft = { typescript = { 'prettierd', 'prettier', stop_after_first = true } }

      })
    end,
  },
  -- add any other plugins here
}
require("lazy").setup(plugins, {
  root = root .. "/plugins",
})

vim.cmd.colorscheme("tokyonight")
-- add anything else here

Can you follow the steps detailed in the debugging docs and come up with a prettier or prettierd invocation that works in your shell?

[killtheliterate]

prettier seems to be functioning as expected now. Seems to be a prettierd issue generally -> fsouza/prettierd#352

I did have success with prettierd restart, after installing prettierd globally, rather than the mason-tools install.

the formatting is not working for me for JS and react based projects. It works for python based projects though.

Formatters for this buffer:

ruff_format ready (python) /Users/username/.local/share/nvim/mason/bin/ruff

this is my conform setup

return {
  "stevearc/conform.nvim",
  event = { "BufReadPre", "BufNewFile" },
  config = function()
    local conform = require("conform")
    conform.setup({
      formatters_by_ft = {
        lua = { "stylua" },
        -- Conform will run multiple formatters sequentially
        python = { "ruff_fix", "ruff_format" },
        javascript = { "prettierd", stop_after_first = true },
        javascriptreact = { "prettierd", stop_after_first = true },
        typescriptreact = { "prettierd", stop_after_first = true },
        graphql = { "prettierd", stop_after_first = true },
        json = { "prettierd" },
      },
      format_on_save = {
        timeout_ms = 2000,
        lsp_format = "fallback",
      },
    })
    vim.keymap.set({ "n", "v" }, "<leader>mp", function()
      conform.format({
        lsp_fallback = true,
        async = false,
        timeout_ms = 2000,
      })
    end, { desc = "Format file or range(in visual mode)" })
  end,
}

formatting is not happening neither while saving nor running mp manually. I do have prettierd(0.26.1) installed globally. I have prettier installed in my project either.
