@skyscanner/eslint-plugin-rules v1.3.0

@skyscanner/eslint-plugin-rules

Eslint plugin containing custom rules used at Skyscanner.

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install @skyscanner/eslint-plugin-rules:

$ npm install @skyscanner/eslint-plugin-rules --save-dev

Note: If you installed ESLint globally (using the -g flag) then you must also install @skyscanner/eslint-plugin-rules globally.

Usage

Add @skyscanner/eslint-plugin-rules to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- part:

{
  "plugins": ["@skyscanner/rules"]
}

Then configure the rules you want to use under the rules section.

{
  "rules": {
    "@skyscanner/rules/no-axios": "error",
    "@skyscanner/rules/forbid-component-props": "error"
  }
}

Supported Rules

no-axios

Detects code importing axios.

Axios it prone to sensitive information leaks due to inclusion of headers in errors it throws.

{
  "rules": {
    "@skyscanner/rules/no-axios": "<severity>"
  }
}

Where <severity> can be one of: error, warn off.
