gulp

Gulp is very old. I would not use it.

It all depends on what framework you are using. They usually come with a bundler. And templates often come with a bundler.

Webpack is the standard Webpack solution. But maybe complicated to use if it does not come with your template or framework. So you may wish to try Parcel first.

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 ;)
