ESLint for Javascript Problems

Phoenix Code provides a comprehensive interface for identifying and resolving ESLint issues in your js/jsx files.

ESLint is only available in desktop apps. In Browsers, JSHint is the default linter for javascript files.

On desktop, JavaScript is also checked by the TypeScript language server, and JSHint turns off automatically.

Basic Usage​

To activate ESLint, the project must have a node package.json file with ESLint as a dependency. Opening a js or jsx file, or editing and saving it, lints the file and shows the results in the Problems panel.

Features​

  • Errors and warnings are underlined directly in the editor.
  • Hovering over a highlighted line provides detailed information about the specific ESLint problem and a suggested fix if available.
  • Fix individual issues by clicking on the Fix button next to the specific problem, or you can resolve all fixable issues in the file by clicking on the Fix All button at the top of the panel.

Advanced Use​

Phoenix Code uses ESLint configured in the opened project directory. Any changes to your ESLint configuration files will be automatically picked up. To learn more about how to use and configure ESLint, see Getting Started with ESLint.

FAQ​

Q: Which version of ESLint are supported​

Phoenix Code supports ESLint versions 7 and above only.

Q: Why is ESLint not working in my project​

Most problems are usually reported in the Problems panel itself. These are the most common errors:

  1. Ensure that ESLint is listed in dependencies or devDependencies section in your package.json file. E.g.
{
    "name": "My Project With ESLint",
    "version": "1.0.0",
    "description": "Sample package.json to activate ESLint",
    "main": "index.js",
    "scripts": {},
    "devDependencies": {
        "eslint": "^8.0.0"
    }
}
  1. Ensure to run npm install on the project and node_modules folder is present in the project at the top level.
  2. ESLint config files may have errors. Check if the problem message contains any references to your ESLint config file.

Note: ESLint runs automatically when you save your file. Issues and errors are displayed in the Problems Panel.
