CodeFactor.io vs ESLint: What are the differences?

Developers describe CodeFactor.io as "Automated Code Review for GitHub & BitBucket". CodeFactor.io automatically and continuously tracks code quality with every GitHub or BitBucket commit and pull request, helping software developers save time in code reviews and efficiently tackle technical debt. On the other hand, ESLint is detailed as "The fully pluggable JavaScript code quality tool". A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript. Maintain your code quality with ease.

CodeFactor.io and ESLint belong to "Code Review" category of the tech stack.

"Easy setup & GitHub integration" is the primary reason why developers consider CodeFactor.io over the competitors, whereas "IDE Integration" was stated as the key factor in picking ESLint.

ESLint is an open source tool with 14.4K GitHub stars and 2.46K GitHub forks. Here's a link to ESLint's open source repository on GitHub.

Asana, Intuit, and Swat.io are some of the popular companies that use ESLint, whereas CodeFactor.io is used by Sofit Software, S.C. Galec, and CodeFactor. ESLint has a broader approval, being mentioned in 541 company stacks & 592 developers stacks; compared to CodeFactor.io, which is listed in 6 company stacks and 4 developer stacks.

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.

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 ;)

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!, :)
