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 fsouza/prettierd/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

Using with TCP (moar speed)

Following the instructions from https://github.com/mantoni/core_d.js#moar-speed:

$ PORT=`cat ~/.prettierd | cut -d" " -f1`
$ TOKEN=`cat ~/.prettierd | cut -d" " -f2`
$ echo "$TOKEN $PWD file.ts" | cat - file.ts | nc localhost $PORT

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

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')),
  },
}

The native TCP client can be used too, I used to do it migrated to
efm-langserver for simplicity, see more details in this blog
post or my
configuration.

Alternatively, one 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 ...
  }
})

I don't know much about other editors, but feel free to send a pull requests on
instructions.
