"But prettier is pretty fast already, right?"

Yes, it's actually super fast. But the node.js startup time and loading all the required modules slows down formatting times. prettier_d reduces this overhead by running a server in the background. It brings the formatting time down from 0.25 seconds to 0.1 seconds on a 3265 byte file If you want to format from within your editor whenever you save a file, prettier_d is for you.

Install

This will install the prettier_d command globally:

yarn global add https://github.com/josephfrazier/prettier_d
# or
npm install -g https://github.com/josephfrazier/prettier_d

Usage

To start the server and format a file, just run:

prettier_d file.js

On the initial call, the prettier_d server is launched and then the given file is formatted. Subsequent invocations are super fast.

How does this work?

The first time you use prettier_d, a little server is started in the background and bound to a random port. The port number is stored along with a token in the root directory of your repo (or ~/.prettier_d if the repo root can't be found). You can then run prettier_d commands the same way you would use prettier and it will delegate to the background server.

Commands

Control the server like this:

prettier_d <command>

Available commands:

• start: start the server
• stop: stop the server
• status: print out whether the server is currently running
• restart: restart the server
• [options] file.js file.js: invoke prettier with the given options. The prettier engine will be created in the current directory. If the server is not yet running, it is started.

prettier_d will select a free port automatically and store the port number along with an access token in the root directory of your repo (or ~/.prettier_d if the repo root can't be found).

Type prettier_d --help to see the supported prettier options.

Editor integration

See https://github.com/prettier/prettier#editor-integration

Real-time formatting in Vim

If you use Vim, and you'd like prettier_d to format your code as you type, install Neoformat and add this to your ~/.vimrc:

autocmd FileType javascript setlocal formatprg=prettier_d\ --parser=babel
autocmd BufWritePre,TextChanged,InsertLeave *.js Neoformat

" Use formatprg when available
let g:neoformat_try_formatprg = 1
" https://github.com/sbdchd/neoformat/issues/25
let g:neoformat_only_msg_on_error = 1

Then, make sure you've started the server: prettier_d start.

This will format your code:

• before each save
• whenever text is changed in normal mode
• whenever you leave insert mode

Intro

Prettier is an opinionated code formatter. It enforces a consistent style by parsing your code and re-printing it with its own rules that take the maximum line length into account, wrapping code when necessary.

Input

foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());

Output

foo(
  reallyLongArg(),
  omgSoManyParameters(),
  IShouldRefactorThis(),
  isThereSeriouslyAnotherOne()
);

Prettier can be run in your editor on-save, in a pre-commit hook, or in CI environments to ensure your codebase has a consistent style without devs ever having to post a nit-picky comment on a code review ever again!
