Usage

Pass a boolean enableAllRules to use the recommended (true, default) or all rules (false):

import { lint } from '@node-rs/deno-lint'

lint(filepath, source, enableAllRules)

Pass the config file content (as string), to be able to specify what rules should be included or excluded:

import { readFile } from 'fs/promises'
import { lint } from '@node-rs/deno-lint'

const config = await readFile('.denolint.json', 'utf8')
lint(filepath, source, config)

webpack-loader

// webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        enforce: 'pre',
        test: /\.(t|j)s?$/,
        loader: '@node-rs/deno-lint/webpack-loader',
        exclude: [/node_modules/],
      },
    ],
  },
}

Options

You can pass denolint options using standard webpack loader options.

enableAllRules

• Type: Boolean | String
• Default: false

Whether to enable all rules. If false, denolint will enable all recommend rules.

Instead of the boolean, a string with the content of .denolint.json can be passed as a value.

failOnError

• Type: Boolean
• Default: false

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

quiet

• Type: Boolean
• Default: false

Emit nothing even if there were errors happened.

denolint cli

usage

npx denolint

--config, -c

{
  "rules": {
    "tags": ["recommended"],
    "exclude": [
      "no-explicit-any",
      "ban-unknown-rule-code",
      "no-window-prefix",
      "no-empty-interface",
      "ban-types",
      "ban-untagged-todo",
      "no-unused-vars",
      "ban-ts-comment",
      "no-case-declarations",
      "no-this-alias"
    ]
  }
}
