ESLint vs Refactor.io: What are the differences?

Introduction

ESLint and Refactor.io are two popular tools used in software development to improve code quality. Below are the key differences between ESLint and Refactor.io.

  1. Scope: ESLint is a static code analysis tool used for identifying and fixing problematic patterns found within JavaScript code, ensuring consistency and maintainability. In contrast, Refactor.io is a code refactoring tool that helps developers improve the design of their codebase by suggesting code changes that can enhance readability, performance, and scalability.

  2. Code Analysis: ESLint focuses on analyzing code for potential errors, style violations, and best practices adherence. It ensures that code follows specific coding standards and guidelines established by the project team. On the other hand, Refactor.io primarily focuses on suggesting automated code refactorings to improve the structure and quality of the codebase without changing its functionality.

  3. Integration: ESLint can be seamlessly integrated into various development environments such as IDEs, build tools, and continuous integration pipelines to provide real-time feedback and enforce code quality standards throughout the development process. Refactor.io, on the other hand, integrates directly into IDEs and code editors to provide on-the-fly suggestions for code improvements as developers write and modify code.

  4. Customization: ESLint offers a high degree of customization through configuration files that allow developers to define specific rules, plugins, and presets according to the project requirements. In contrast, Refactor.io provides a set of predefined refactoring actions based on common design patterns and principles, limiting the customization options available to developers.

  5. Automation Level: ESLint primarily relies on developers to manually review and fix the identified code issues based on the provided feedback. In contrast, Refactor.io automates the process of suggesting and applying code refactorings, aiming to streamline the code improvement process and reduce manual intervention.

  6. Feedback Mechanism: ESLint provides detailed reports and error/warning messages directly within the code editor or through the command line interface, allowing developers to quickly identify and address code quality issues. Refactor.io, on the other hand, offers actionable suggestions for code improvements alongside explanations of the suggested refactorings to help developers understand and apply the changes effectively.

In Summary, ESLint focuses on static code analysis and enforcing coding standards, while Refactor.io specializes in automated code refactoring suggestions to enhance code quality and maintainability.

Advice on ESLint, Refactor.io

Needs adviceonPrettierPrettierESLintESLintgulpgulp

Scenario: I want to integrate Prettier in our code base which is currently using ESLint (for .js and .scss both). The project is using gulp.

It doesn't feel quite right to me to use ESLint, I wonder if it would be better to use Stylelint or Sass Lint instead.

I completed integrating ESLint + Prettier, Planning to do the same with [ Stylelint || Sasslint || EsLint] + Prettier.

And have gulp 'fix' on file save (Watcher).

Any recommendation is appreciated.

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 ;)
