JS Beautifier vs Prettier: What are the differences?

  1. Key Difference 1: Syntax Support JS Beautifier focuses on formatting JavaScript code, providing support for different syntax styles, including the popular JS Beautify syntax. On the other hand, Prettier supports various programming languages beyond JavaScript, such as CSS, HTML, JSON, and Markdown, enhancing its versatility and applicability.

  2. Key Difference 2: Opinionated vs Configurable JS Beautifier offers a range of configurable options, allowing developers to customize the formatting rules according to their preferences. In contrast, Prettier takes an opinionated approach by enforcing a consistent formatting style and offering minimal configuration. Prettier's style decisions are based on community best practices and conventions, reducing the need for manual adjustments.

  3. Key Difference 3: White Space Handling JS Beautifier primarily focuses on formatting code structure while preserving white spaces already present in the code. It maintains the original indentation and formatting rules. Conversely, Prettier applies automatic and opinionated formatting to remove unnecessary white spaces, ensuring consistency and reducing the need to manually handle whitespace-related issues.

  4. Key Difference 4: Code Reformatting JS Beautifier formats the code structure while preserving the existing code layout. It does not make significant changes to the original code, such as changing line breaks or aligning code elements. Prettier, however, performs a more extensive code reformatting, rearranging code elements, aligning parentheses, and swapping line breaks to enhance code readability and aesthetics.

  5. Key Difference 5: Code Parsing and Rebuilding JS Beautifier modifies the code by utilizing a parsing mechanism to analyze the code structure and rebuilding it while adhering to the specified formatting rules. On the other hand, Prettier employs an advanced parsing engine that fully understands the code syntax, allowing it to make more accurate and sophisticated code formatting decisions, resulting in a more consistent and standardized output.

  6. Key Difference 6: IDE Integration and Command Line Usage JS Beautifier provides IDE integrations and allows developers to run it as a stand-alone command-line tool, offering flexibility in various development workflows. Prettier also offers IDE integrations and command-line usage but is widely recognized for its seamless integration with popular code editors, providing a smoother and more convenient formatting experience.

In Summary, JS Beautifier primarily focuses on JavaScript code formatting with configurable options, while Prettier supports multiple programming languages, follows an opinionated style, and achieves more extensive code reformatting with accurate code parsing.

Advice on JS Beautifier, Prettier

Review

you don't actually have to choose between these tools as they have vastly different purposes. i think its more a matter of understanding how to use them.

while eslint and stylelint are used to notify you about code quality issues, to guide you to write better code, prettier automatically handles code formatting (without notifying me). nothing else.

prettier and eslint both officially discourage using the eslint-plugin-prettier way, as these tools actually do very different things. autofixing with linters on watch isnt a great idea either. auto-fixing should only be done intentionally. you're not alone though, as a lot of devs set this up wrong.

i encourage you to think about what problem you're trying to solve and configure accordingly.

for my teams i set it up like this:

  • eslint, stylelint, prettier locally installed for cli use and ide support
  • eslint config prettier (code formatting rules are not eslints business, so dont warn me about it)
  • vscode workspace config: format on save
  • separate npm scripts for linting, and formatting
  • precommit hooks (husky)

so you can easily integrate with gulp. its just js after all ;)

Prettier
Prettier

This little beautifier will reformat and reindent bookmarklets, ugly JavaScript, unpack scripts packed by Dean Edward’s popular packer, as well as deobfuscate scripts processed by javascriptobfuscator.com.

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.

-
An opinionated code formatter; Supports many languages; Integrates with most editors; Has few options; You press save and code is formatted; No need to discuss style in code review; Saves you time and energy
