Package description
The babel-eslint npm package is a parser that allows you to lint all valid Babel code with the ESLint linter. It is designed to be used with ESLint and Babel, providing compatibility between the two and allowing developers to use ESLint on code that contains Babel-specific syntax.
Parsing Babel Code for ESLint
This feature allows developers to configure ESLint to use babel-eslint as the parser, enabling ESLint to understand and lint code that includes Babel-specific syntax that is not yet supported by ESLint's default parser.
module.exports = { parser: 'babel-eslint', rules: { /* ESLint rules */ } };Experimental Syntax Support
babel-eslint can parse experimental syntax such as class properties and async functions, which might not be supported by ESLint's default parser. This allows developers to use ESLint on projects that make use of the latest JavaScript features.
class MyClass { async myMethod() { /* ... */ } }Custom Babel Configuration
babel-eslint allows developers to specify a custom Babel configuration file, ensuring that the parser understands the code in the same way Babel does when it transpiles the code.
{ "parserOptions": { "babelOptions": { "configFile": "path/to/your/babel.config.js" } } }This package is a parser that allows ESLint to lint TypeScript code. It is similar to babel-eslint in that it extends ESLint's capabilities to understand syntax not natively supported by ESLint. However, it is specifically designed for TypeScript, whereas babel-eslint is focused on Babel-specific JavaScript syntax.
This package is an ESLint plugin that provides linting rules for Flow, a static type checker for JavaScript. Like babel-eslint, it extends ESLint's functionality to additional syntax features, but it is tailored for Flow type annotations rather than Babel's JavaScript transformations.
Prettier is an opinionated code formatter that supports many languages, including JavaScript. While it is not a linter like ESLint or a parser like babel-eslint, it is often used in conjunction with ESLint to enforce consistent code formatting. Prettier can parse and format code with Babel-specific syntax when used with the appropriate plugins.
Readme
babel-eslint allows you to lint ALL valid Babel code with the fantastic ESLint.
NOTE: Please note that this is experimental and may have numerous bugs. It is however successfuly linting the babel core.
ESLint allows custom parsers. This is great but some of the syntax nodes that Babel supports aren't supported by ESLint. When using this plugin, ESLint is monkeypatched and your code is transformed into code that ESLint can understand. All location info such as line numbers, columns is also retained so you can track down errors with ease.
