@dtwojs/eslint-module

ESLint module for Dtwo.js

Requirements

You need to ensure that you have eslint >= 7 installed:

yarn add --dev eslint # or npm install --save-dev eslint

Setup

1. Add @dtwojs/eslint-module dependency to your project

yarn add --dev @dtwojs/eslint-module # or npm install --save-dev @dtwojs/eslint-module

2. Add @dtwojs/eslint-module to the buildModules section of dtwo.config.js

export default {
  buildModules: [
    // Simple usage
    '@dtwojs/eslint-module',

    // With options
    ['@dtwojs/eslint-module', { /* module options */ }]
  ]
}

:warning: If you are using Dtwo < v2.9 you have to install the module as a dependency (No --dev or --save-dev flags) and use modules section in dtwo.config.js instead of buildModules.

Using top level options

export default {
  buildModules: [
    '@dtwojs/eslint-module'
  ],
  eslint: {
    /* module options */
  }
}

Options

You can pass eslint options.

Note that the config option you provide will be passed to the ESLint class. This is a different set of options than what you'd specify in package.json or .eslintrc. See the eslint docs for more details.

cache

• Type: Boolean
• Default: true

Note: The cache is enabled by default to decrease execution time.

context

• Type: String
• Default: srcDir

A string indicating the root of your files.

eslintPath

• Type: String
• Default: eslint

Path to eslint instance that will be used for linting.

exclude

• Type: String|Array[String]
• Default: 'node_modules'

Specify the files and/or directories to exclude. Must be relative to options.context.

extensions

• Type: String|Array[String]
• Default: ['js', 'ts', 'kdu']

Specify extensions that should be checked.

files

• Type: String|Array[String]
• Default: null

Specify directories, files, or globs. Must be relative to options.context. Directories are traversed recursively looking for files matching options.extensions. File and glob patterns ignore options.extensions.

fix

• Type: Boolean
• Default: false

Will enable ESLint autofix feature.

Be careful: this option will change source files.

formatter

• Type: String|Function
• Default: 'stylish'

Accepts a function that will have one argument: an array of eslint messages (object). The function must return the output as a string. You can use official eslint formatters.

lintDirtyModulesOnly

• Type: Boolean
• Default: true

Lint only changed files, skip lint on start.

threads

• Type: Boolean | Number
• Default: false

Will run lint tasks across a thread pool. The pool size is automatic unless you specify a number.

Errors and Warning

By default the plugin will auto adjust error reporting depending on eslint errors/warnings counts. You can still force this behavior by using emitError or emitWarning options:

emitError

• Type: Boolean
• Default: false

Will always return errors, if set to true.

emitWarning

• Type: Boolean
• Default: false

Will always return warnings, if set to true.

failOnError

• Type: Boolean
• Default: false

Will cause the module build to fail if there are any errors, if set to true.

failOnWarning

• Type: Boolean
• Default: false

Will cause the module build to fail if there are any warnings, if set to true.

quiet

• Type: Boolean
• Default: false

Will process and report errors only and ignore warnings, if set to true.

outputReport

• Type: Boolean|Object
• Default: false

Write the output of the errors to a file, for example a checkstyle xml file for use for reporting on Jenkins CI.

The filePath is an absolute path or relative to the webpack config: output.path. You can pass in a different formatter for the output file, if none is passed in the default/configured formatter will be used.
