Airbnb JavaScript Style Guide vs Prettier

Which should you use? A side-by-side look at what each one does, who it suits, what it costs, how hard it is to set up, and where each falls short.

A widely used style guide with rules and ESLint configs for writing consistent JavaScript.

Prettier

Open source · MIT

An opinionated code formatter that rewrites your code in one consistent style.

Our verdict

Airbnb JavaScript Style Guide is a written set of rules about how JavaScript should be written, from naming to modern syntax, with optional ESLint configs that check many of them automatically. Prettier is a tool that automatically reformats your code into one fixed layout, covering spacing and line breaks rather than naming or language patterns. They solve different problems, so they are not really rivals; many teams could reasonably use both, with the guide setting conventions and Prettier handling formatting.

Pick Airbnb JavaScript Style Guide if you want a documented set of JavaScript conventions and examples to share with your team or learn from.

Pick Prettier if you want code formatting handled automatically on save or in commit checks so nobody argues about spacing and line breaks.

What each one is

Airbnb JavaScript Style Guide

This is a written style guide for JavaScript, covering how to name things, format code, and use modern language features. Each rule is paired with examples of 'bad' and 'good' code and often a short explanation of why. The README also points to ESLint configs (eslint-config-airbnb and eslint-config-airbnb-base) that automatically enforce many of these rules in a project.

Prettier

Prettier reads your source code, parses it, and reprints it using its own fixed formatting rules, wrapping lines when they exceed a maximum length. It supports many languages, including JavaScript, TypeScript, CSS, JSON, Markdown, and YAML. Teams use it so everyone's code looks the same and code reviews don't turn into debates about spacing and line breaks.

Best for

Airbnb JavaScript Style Guide

  • Teams that want one shared JavaScript style without debating every rule
  • Developers who want a documented set of modern JavaScript conventions
  • Projects that already use ESLint and want a ready-made rule set
  • Developers learning ES2015+ syntax who want clear examples

  • Developers who want formatting handled automatically on save
  • Projects that use JavaScript, TypeScript, CSS, or Markdown
  • Setups that run formatting in a pre-commit hook or CI check

Strengths

Airbnb JavaScript Style Guide

  • Widely adopted, with rules that are explained with examples
  • Maps many rules to specific ESLint rules, so enforcement can be automated
  • Covers a broad range of topics, from types and naming to testing and performance

Prettier

  • Removes formatting debates from code review by applying one consistent style
  • Supports many languages in one tool, as listed in the README
  • Widely used, with an active repository and a recent release (3.9.10)

Not ideal for

Airbnb JavaScript Style Guide

  • Projects that already follow a different established style and do not want to change, since adopting it means many edits
  • Developers who need a guide for CSS, React, or Ruby specifically, since those are separate guides linked from the README
  • Teams targeting environments where the README's Babel and polyfill assumptions do not hold, since the guide assumes those tools are in use

Prettier

  • People who want to customize every formatting detail, since Prettier is opinionated and offers limited options (the README links to an Options page, which was not reviewed here)
  • Projects in languages not listed in the README, unless a plugin exists for them

Trade-offs

Airbnb JavaScript Style Guide

  • It is opinionated; some rules are subjective and not every team will agree with them
  • The README assumes Babel and polyfill tooling, which adds setup for projects that do not use them
  • The README excerpt provided is truncated, so the full scope of later sections could not be verified here

Prettier

  • Its opinionated style means limited control over individual formatting choices
  • Teams with an established, different style may need to reformat existing code, which creates large diffs

Getting started

Prettier

Install with npm (from the project's install docs; README excerpt does not include the command)
