ECMAScript code beautifier/formatter.
This tool is still missing support for many important features. Please report any bugs you find, the code is only as good as the test cases. Feature requests are very welcome.
We are looking for contributors!!
For more reasoning behind it and history of the project see: esformatter & rocambole
- granular control about white spaces, indent and line breaks.
- command line interface (cli).
- be non-destructive.
- support for local/global config file so settings can be shared between team members.
- be extensive (plugins and other cli tools).
- support most popular style guides through plugins (Google, jQuery, Idiomatic.js).

See the doc/api.md file for a list of all the public methods and detailed documentation about each one.
See doc/config.md for more info about the configuration options.
You can also use the simple command line interface to process the
read from a file.
npm install [-g] esformatter
--help flag to see the available options or see

If a locally installed
esformatter is found, the CLI uses that instead of the
global executable (this means you can have multiple projects depending on
different versions of esformatter).
esformatter and all the plugins that you need on your project
to the package.json
that way you can use locally installed plugins and also make sure everyone on
your team is using the same version/settings.
IDE / Editor integration
Since esformatter is available as a command-line tool, it can be used in any editor that supports external shell commands.
- Vim - vim-esformatter
- Sublime Text - sublime-esformatter
- Atom - atom-esformatter
- Visual Studio Code - vscode-esformatter
Presets are reusable config files that can
require other presets/plugins and
// presets are used as "base settings""extends":"preset:foobar" // load "esformatter-preset-foobar" from "./node_modules""./lorem_ipsum.json" // load relative config file// you can still override any setting from the preset if needed"indent":"value": " "
For more info see presets.md
Pipe other CLI tools
Since we don't expect everyone to write plugins that only works with esformatter we decided to encourage the usage of standalone CLI tools.
// pipe is a simple way to "pipe" multiple binaries input/output"pipe":// scripts listed as "before" will be executed before esformatter// and will forward output to next command in the queue"before":"strip-debug""./bin/my-custom-script.sh --foo true -zx"// scripts listed as "after" will be executed after esformatter"after":"baz --keepLineBreaks"
Plugins are automatically loaded from
node_modules if you pass the module id
in the config file:
