prettier

Pros of ESLint

• More customizable and configurable, allowing for fine-tuned rule sets
• Capable of detecting logical errors and potential bugs, not just style issues
• Supports plugins for extended functionality and language-specific rules

Cons of ESLint

• Requires more setup and configuration to get started
• Can be slower to run, especially on large codebases
• May lead to debates within teams about specific rule choices

Code Comparison

ESLint (with custom rules):

// eslint-disable-next-line no-unused-vars
function example(param1, param2) {
  const result = param1 + param2;
  return result;
}

Prettier (default formatting):

function example(param1, param2) {
  const result = param1 + param2;
  return result;
}

ESLint focuses on identifying potential issues and enforcing coding standards, while Prettier is primarily concerned with consistent code formatting. ESLint's output may include warnings about unused variables or suggest more idiomatic code structures, whereas Prettier would simply format the code according to its predefined style rules.

Both tools serve different purposes and can be used together in a development workflow. ESLint excels at catching potential errors and enforcing best practices, while Prettier ensures consistent code formatting across a project.

Pros of JSHint

• More flexible and customizable linting rules
• Focuses on detecting potential errors and problematic patterns
• Integrates well with various build tools and IDEs

Cons of JSHint

• Doesn't automatically fix code issues
• Limited formatting capabilities
• Less active development and community support

Code Comparison

JSHint (linting):

function example(x) {
    if (x == null) return;
    var y = x + 1;
    console.log(y);
}

Prettier (formatting):

function example(x) {
  if (x == null) return;
  var y = x + 1;
  console.log(y);
}

JSHint focuses on identifying potential issues in the code, such as using == instead of === for null checks. Prettier, on the other hand, automatically formats the code to a consistent style, adjusting indentation and line breaks.

While JSHint provides valuable insights into code quality and potential bugs, Prettier excels at maintaining consistent code formatting across projects. JSHint is better suited for catching logical errors and enforcing coding standards, whereas Prettier is ideal for eliminating debates about code style and ensuring uniform formatting.

Many developers use both tools in conjunction, with JSHint for linting and Prettier for formatting, to achieve both code quality and consistent style in their projects.

Pros of Standard

• Simpler setup with zero configuration required
• Includes both linting and formatting in a single package
• Opinionated style guide that promotes consistency across projects

Cons of Standard

• Less flexible and customizable than Prettier
• Limited language support compared to Prettier's wide range
• Smaller community and ecosystem

Code Comparison

Standard:

function example (foo) {
  if (foo) {
    return foo
  }
  return bar
}

Prettier:

function example(foo) {
  if (foo) {
    return foo;
  }
  return bar;
}

Standard enforces no semicolons and space before function parentheses, while Prettier adds semicolons and removes the space before function parentheses by default.

Summary

Standard offers a simpler, opinionated approach with built-in linting, making it ideal for teams wanting a quick, consistent setup. Prettier provides more flexibility, broader language support, and a larger ecosystem, but requires additional configuration for linting. The choice between them depends on project requirements and team preferences.

Pros of stylelint

• Highly customizable with extensive rule set for CSS and preprocessors
• Supports plugins for additional functionality and custom rules
• Provides detailed error messages and suggestions for fixes

Cons of stylelint

• Requires more configuration and setup compared to Prettier
• Can be slower to run, especially on large codebases
• May require more maintenance as CSS specifications evolve

Code Comparison

stylelint configuration example:

{
  "rules": {
    "color-hex-case": "lower",
    "indentation": 2,
    "selector-max-id": 0
  }
}

Prettier configuration example:

{
  "printWidth": 80,
  "tabWidth": 2,
  "singleQuote": true
}

Key Differences

• stylelint focuses specifically on CSS and related languages, while Prettier is a more general-purpose formatter
• stylelint offers more granular control over styling rules, whereas Prettier aims for consistent formatting with fewer options
• stylelint can catch potential errors and enforce best practices, while Prettier primarily focuses on code formatting

Use Cases

• Use stylelint when you need detailed control over CSS styling rules and want to enforce specific coding standards
• Choose Prettier for quick and consistent formatting across multiple languages with minimal configuration

Both tools can be used together in a project, with stylelint handling CSS-specific linting and Prettier managing overall code formatting.

Pros of Rome

• All-in-one toolchain: Rome combines linting, formatting, bundling, and more
• Faster performance due to being built in Rust
• Designed for extensibility and customization

Cons of Rome

• Less mature and stable compared to Prettier
• Smaller community and ecosystem
• Limited language support (primarily focused on JavaScript/TypeScript)

Code Comparison

Rome:

function greet(name) {
  return `Hello, ${name}!`;
}

Prettier:

function greet(name) {
  return `Hello, ${name}!`;
}

In this simple example, both Rome and Prettier produce identical output. However, Rome's formatting rules can be more opinionated and may differ in more complex scenarios.

Key Differences

• Scope: Rome aims to be a comprehensive toolchain, while Prettier focuses solely on code formatting
• Language support: Prettier supports a wider range of languages
• Configuration: Rome offers more granular control over formatting rules
• Performance: Rome generally performs faster due to its Rust implementation
• Community: Prettier has a larger user base and more widespread adoption

Conclusion

While Rome offers an ambitious all-in-one solution with potential performance benefits, Prettier remains the more established and widely-supported option for code formatting. The choice between the two depends on project requirements, language needs, and desired toolchain integration.

Pros of TSLint

• More granular control over linting rules and configurations
• Specifically designed for TypeScript, offering deeper language-specific checks
• Supports custom rule creation for project-specific needs

Cons of TSLint

• Slower performance, especially on larger codebases
• Discontinued and no longer actively maintained
• Steeper learning curve due to more complex configuration options

Code Comparison

TSLint configuration example:

{
  "rules": {
    "no-unused-variable": true,
    "semicolon": [true, "always"],
    "quotemark": [true, "single"]
  }
}

Prettier configuration example:

{
  "semi": true,
  "singleQuote": true,
  "trailingComma": "es5"
}

TSLint focuses on linting rules and code quality, while Prettier emphasizes consistent code formatting. TSLint offers more fine-grained control but requires more setup, whereas Prettier provides a simpler, opinionated approach to code style.

TSLint has been deprecated in favor of ESLint with TypeScript support, while Prettier continues to be actively maintained and widely adopted for its simplicity and integration with various tools and editors.
