ESLint vs Hound: What are the differences?
# Introduction
Setup and Configuration: ESLint is a pluggable linting utility for JavaScript and JSX, while Hound is specifically designed for Ruby code. The setup and configuration process for ESLint involves installing ESLint via npm and creating an ESLint configuration file, whereas Hound requires the Hound gem to be added to the Gemfile and configured through a
.hound.ymlfile.Rule Customization: ESLint offers a wide range of customizable rules that can be adjusted to fit specific coding styles and preferences. On the other hand, Hound has a predefined set of rules that cannot be modified, providing a more standardized approach to linting Ruby code.
Flexibility: ESLint provides flexibility in the sense that developers can choose from a variety of plugins and configuration options to tailor the linting process to their needs. In contrast, Hound is more rigid in terms of rule enforcement, offering a simpler, less customizable linting experience.
Language Support: ESLint is primarily focused on JavaScript and JSX linting, but it also has support for other languages such as TypeScript and Vue.js. In comparison, Hound is specifically designed for Ruby code linting, making it a more specialized tool for Ruby developers.
Popular Usage: ESLint is widely used in the JavaScript community and has a large user base with extensive documentation and community support. While Hound is popular among Ruby developers, it may not have the same level of widespread adoption and community resources as ESLint.
Integration with Tools: ESLint integrates seamlessly with various development tools and IDEs, allowing developers to run linting checks directly within their workflow. On the other hand, Hound may have limited integration options compared to ESLint, potentially impacting the ease of use for developers.
In Summary, ESLint and Hound differ in setup and configuration, rule customization, flexibility, language support, popular usage, and integration with tools.
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.
In the case of .js files I would recommend using both Eslint and Prettier.
You can set up Prettier as an Eslint rule using the following plugin:
https://github.com/prettier/eslint-plugin-prettier
And in order to avoid conflicts between Prettier and Eslint, you can use this config:
https://github.com/prettier/eslint-config-prettier
Which turns off all Eslint rules that are unnecessary or might conflict with Prettier.
Pura vida! Well, I had a similar issue and at the end I decided to use Stylelint + Prettier for that job, in our case, we wanted that our linting process includes the SCSS files and not only the JS file, base on that we concluded that using only ESLint to do both things wasn't the best option, so, we integrated prettier with Stylelint, and for that we used a neat plugin that allowed us to use Prettier inside Stylelint here is the link, https://github.com/prettier/stylelint-prettier#recommended-configuration, I hope that this can help you, hasta pronto!, :)
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 ;)
