如何让 eslint-plugin-import 为我的 npm 项目 (create-react-app) 工作？

Question

I just did npm install eslint-plugin-import --save-dev .

I expect react-app NOT to compile because it should flag an import misspelling. The app is compiling fine.

How do I start using the linter?

I don't understand the instructions ( https://www.npmjs.com/package/eslint-plugin-import ) when it says:

1) "if you manage ESLint as a dev dependency"

2) Manual configuring the .eslintrc.(yml|json|js) ... how does this work?

Answer 1

1) "if you manage ESLint as a dev dependency"

it means that you need to install the module as a development dependency , in contrast to production dependencies .

the installation of development\production dependencies can be controlled using npm install --production

With the --production flag (or when the NODE_ENV environment variable is set to production), npm will not install modules listed in devDependencies .

now for your second question

2) Manual configuring the.eslintrc.(yml|json|js)... how does this work?

.eslintrc.js (or eslintrc.yml , or eslintrc.json ) file is used to control and configure how eslint behaves in your project.

for instance, you can use eslintrc.js file to enable and disable eslint rules.
