🛡️ SafeCode Pro

SafeCode Pro is a Visual Studio Code extension designed to enhance code safety and enforce naming conventions in JavaScript and JSX code. It detects unsafe object/array usage, missing null checks, and ensures consistent and meaningful naming patterns.

✨ Features

• ✅ Warns when using Object.keys(data) or other object methods without checking if data is an object via isObject(data)
• ✅ Highlights unsafe array method calls when the variable may not be an array (e.g., data.map() without Array.isArray(data))
• ✅ Detects missing null-safe access (e.g., data.name vs data?.name)
• ✅ Enforces camelCase naming convention
• ✅ Variable naming rules:
  • o prefix for objects → e.g., oUser
  • a prefix for arrays → e.g., aItems
  • is prefix for booleans → e.g., isValid
  • Functions must start with a verb (e.g., getData, setUser)
  • Setter functions (e.g., from React's useState) must start with set
• 🧠 Skips commented lines and multi-line comments
• 🔍 Analyzes line-by-line for performance and clarity

📂 Supported File Types

TypeScript support is under consideration.

🧠 Code Safety Examples

❗ Unsafe Object Access

Object.keys(data); // ⛔ unsafe if data is not checked

✅ Use:

if (isObject(data)) {
  Object.keys(data);
}

❗ Unsafe Array Access

data.map(item => item.name); // ⛔ unsafe if data is not an array

✅ Use:

if (Array.isArray(data)) {
  data.map(item => item.name);
}

❗ Unsafe Property Access

const name = data.name; // ⛔ unsafe if data is null/undefined

✅ Use:

const name = data?.name; // ✅ safe access

✅ Naming Conventions

❌ Invalid:

let UserData = {}; // PascalCase ❌
const infoList = []; // missing array prefix ❌
const valid = true; // no 'is' prefix ❌

✅ Valid:

let oUserData = {};
const aInfoList = [];
const isValid = true;
