A set of eslint rules to enforce best practices in the development of Babel plugins.

You'll first need to install ESLint:

$ npm install --save-dev eslint

Next, install @babel/eslint-plugin-development:

$ npm install --save-dev @babel/eslint-plugin-development

Then, load the plugin in your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
  "plugins": ["@babel/development"]
}

Note: Rules marked with 🔧 are autofixable.

• @babel/development/no-deprecated-clone (:wrench:): Disallows using the deprecated t.clone(node) and t.cloneDeep(node) methods from @babel/types. Those calls are replaced with t.cloneNode(node) when using eslint --fix.
• @babel/development/no-undefined-identifier: Disallows using t.identifier("undefined") to create a node which represents an undefined value, since it might cause problem if undefined is redeclared.
• @babel/development/plugin-name: Requires plugins to have a name property, which can be useful for debugging purposes.
