Wanna run prettier in your editor, but fast? Welcome to prettierd!

This is built on top of core_d.js and integrates with prettier.

Installation guide

$ npm install -g @fsouza/prettierd

NOTE: npm comes builtin to node.

Alternatively, users may also use homebrew:

$ brew install prettierd

Using in the command line with node.js

The prettierd script always takes the file in the standard input and the positional parameter with the name of the file:

$ cat file.ts | prettierd file.ts

Supported languages / plugins

Many parsers ship with prettierd, including JavaScript, TypeScript, GraphQL, CSS, HTML and YAML. Please notice that starting with version 0.12.0, prettierd now supports invoking the local version of prettier, so instead of adding new languages to prettierd, you should rely on that feature to use it locally with your custom version of prettier and enabled plugins.

Additional plugins

Additional plugins can be supported by installing them and adding them to the prettier configuration. For example, to use the Ruby plugin, install @prettier/plugin-ruby and add it to your configuration:

{
  // ... other settings
  "plugins": ["@prettier/plugin-ruby"],
}

Then formatting Ruby files should be possible.

Provide Default Configuration

You can provide a default configuration for the prettier via setting the environment variable PRETTIERD_DEFAULT_CONFIG to the exact path of the prettier configuration file.

Local Instance

If you have locally installed prettier in your package, it will use that. Otherwise, it will use the one bundled with the package itself.

If you want to use prettierd exclusively with the locally installed prettier package, you can set the environment variable PRETTIERD_LOCAL_PRETTIER_ONLY (any truthy value will do, good examples are true or 1).

Editor integration

Vim / Neovim

I use this directly with neovim's LSP client, via efm-langserver:

local prettier = {
  formatCommand = 'prettierd "${INPUT}"',
  formatStdin = true,
  env = {
    string.format('PRETTIERD_DEFAULT_CONFIG=%s', vim.fn.expand('~/.config/nvim/utils/linter-config/.prettierrc.json')),
  },
}

Alternatively, you can use prettierme to integrate directly with other editors.

Or, as a third option for users of Vim/Neovim plugins such as formatter.nvim or vim-codefmt, you can configure prettierd in the stdin mode. Below is an example with formatter.nvim:

require('formatter').setup({
  logging = false,
  filetype = {
    javascript = {
        -- prettierd
       function()
          return {
            exe = "prettierd",
            args = {vim.api.nvim_buf_get_name(0)},
            stdin = true
          }
        end
    },
    -- other formatters ...
  }
})

Sublime Text

Prettierd Format

You can use Prettierd Format to format your files with prettierd. After installation, it enables format-on-save for any file supported by Prettier by default.

Fmt

Alternatively, if you're looking for something more advanced that supports multiple formatters, you can use Fmt and configure prettierd for each language scope you wish to format:

{
  "rules": [
    {
      "selector": "source.ts",
      "cmd": ["prettierd", "--stdin-filepath", "$file"],
      "format_on_save": true,
    },
    {
      "selector": "source.json",
      // ...
    },
    // ...
  ],
}

Zed

To use Prettierd with Zed, you need to configure the language_overrides adding a format_on_save command for each of the languages you wish to be handling.

[!NOTE] Configuration below assumes you have installed prettierd and gives an example of its path from Homebrew installation. You can check path on your system by running which prettierd.

Example configuration:

{
  "language_overrides": {
    "TypeScript": {
      "format_on_save": {
        "external": {
          "command": "/opt/homebrew/bin/prettierd",
          "arguments": ["--stdin-filepath", "{buffer_path}"]
        }
      }
    }
  }
}

Save your configuration file, and provided you've installed and set the correct path to prettierd program, Zed will start formatting your files on save action.
