Helpful settings for ESLint in VS Code

settings.json

{
    "[javascript]": {
        "editor.rulers": [
            100
        ],
    },
    "[javascriptreact]": {
        "editor.rulers": [
            100
        ],
    },
    "editor.codeActionsOnSave": {
        "source.fixAll.eslint": true,
    },
    "eslint.format.enable": true,
    "eslint.validate": ["javascript", "javascriptreact", "jsx"],
}

Notes:

• An editor ruler (editor.rulers) creates a visual reference for ESLints max-len rule.
• editor.codeActionsOnSave with the "source.fixAll.eslint": true, value allows the editor to apply all ESLint fixes on save.
