Lints and fixes files. If no specific files are given, it lints all files in `src` and `test`.
|
|
|
|
Other [ESLint CLI options](https://eslint.org/docs/user-guide/command-line-interface#options) are also supported.
|
|
|
|
## Configuration
|
|
|
|
ESLint can be configured via `.eslintrc` or the `eslintConfig` field in `package.json`.
|
|
|
|
Lint-on-save during development with `eslint-loader` is enabled by default. It can be disabled with the `lintOnSave` option in `vue.config.js`:
|
|
|
|
``` js
|
|
module.exports = {
|
|
lintOnSave: false
|
|
}
|
|
```
|
|
|
|
When set to `true`, `eslint-loader` will emit lint errors as warnings. By default, warnings are only logged to the terminal and does not fail the compilation.
|
|
|
|
To make lint errors show up in the browser overlay, you can use `lintOnSave: 'error'`. This will force `eslint-loader` to always emit errors. this also means lint errors will now cause the compilation to fail.
|
|
|
|
Alternatively, you can configure the overlay to display both warnings and errors:
|
|
|
|
``` js
|
|
// vue.config.js
|
|
module.exports = {
|
|
devServer: {
|
|
overlay: {
|
|
warnings: true,
|
|
errors: true
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
When `lintOnSave` is a truthy value, `eslint-loader` will be applied in both development and production. If you want to disable `eslint-loader` during production build, you can use the following config:
|
|
|
|
``` js
|
|
// vue.config.js
|
|
module.exports = {
|
|
lintOnSave: process.env.NODE_ENV !== 'production'
|
|
}
|
|
```
|
|
|
|
## Installing in an Already Created Project
|
|
|
|
``` sh
|
|
vue add @vue/eslint
|
|
```
|
|
|
|
## Injected webpack-chain Rules
|
|
|
|
- `config.module.rule('eslint')`
|
|
- `config.module.rule('eslint').use('eslint-loader')`
|
