Why is the "plugins" value in the eslint config important?

During my eslint configuration process, I came across a situation where some preconfigured plugins recommended including the "plugins" : [] value in my config (typescript), while others did not suggest it (stencil).

In the aforementioned Typescript plugin documentation, it is explained that

plugins: ['@typescript-eslint'] tells ESLint to load the @typescript-eslint/eslint-plugin package as a plugin.

  • This enables you to use typescript-eslint's rules within your codebase.

But why would I need to do this if the --print-config flag generates the same config regardless of whether I include the plugins or not? The linting still works perfectly without them. So what purpose does setting this additional value serve?

Answer №1

While going through the documentation for the accessibility plugin, I came across this specific note:

When extending our configuration, it's unnecessary to include "plugins": ["jsx-a11y"] in your .eslintrc file.

This appears to be the solution. By using the recommended ruleset, the plugin is automatically added to eslint's plugins list internally. I confirmed this for all three plugins linked in this question and answer post.
