🛡️ SafeCode Pro

SafeCode Pro is a powerful Visual Studio Code extension designed to enforce safe coding standards and prevent runtime errors in JavaScript and AngularJS projects.
It detects unsafe patterns, enforces naming rules, blocks ES6 syntax inside AngularJS folders, and checks only modified lines using Git — just like GitLens.

✨ Features

🧠 Smart Safety & Null-Check Detection

• Detects unsafe object method usage
  (Object.keys, Object.values, Object.entries, Reflect.ownKeys, etc.)
• Highlights unsafe array method usage
  (map, filter, reduce, find, etc.)
• Detects unsafe property access
  (data.name → use data?.name)
• Automatically skips:
  • Comments (//, /* */)
  • Imports & requires
  • Assignments (obj.a.b = 10)
  • Known safe globals (console, Math, JSON, etc.)

🔍 Git-Aware Modified Line Scanning

SafeCode Pro checks only the changed lines, not the whole file:

✔ Modified lines
✔ Newly added lines
✔ Works after restarting VS Code
✔ Untracked (new) files → scans entire file
✔ Faster and behaves exactly like GitLens

🏗️ Multi-Line Safe Block Detection

Variables inside safe blocks automatically become safe:

if (Array.isArray(data)) {
  data.map(() => {});      // safe
  data.filter(() => {});   // safe
}

if (isObject(user)) {
  Object.keys(user);       // safe
}


.

🛑 ES6 Blocking for AngularJS Projects

Inside:

/public/app/**/*.js


SafeCode Pro blocks ES6+ syntax:

✔ let, const

✔ Arrow functions ()=>

✔ Template literals `text`

✔ Destructuring {a,b}=obj & [x,y]=arr

✔ Spread operator ...

✔ Classes

✔ import / export

✔ async, await

✔ Native Promise (suggest \$q instead)

✔ Ideal for teams maintaining legacy AngularJS codebases.


## 🏛️ Naming Convention Enforcement

| Type      | Rule                     | Example     |
|-----------|---------------------------|-------------|
| Object    | Must start with `o`       | `oUser`     |
| Array     | Must start with `a`       | `aItems`    |
| Boolean   | Must start with `is`      | `isActive`  |
| Functions | Must start with a verb    | `getData()` |
| Setters   | Must start with `set`     | `setUser()` |

### React `useState` Rule

```js
const [user, setUser] = useState({});

🧠 Code Safety Examples


❗ Unsafe Object Access

```js
Object.keys(data);


✅ 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
