## Install
```shell
npm i @xpr/local-storage
```
## Usage
```typescript
import { localStorage, getStore } from '@xpr/local-storage';
const app = express();
// The middleware starts an async hooks trap.
//
// From now on, every function called after
// this middleware run, can access the [[Request]]
// and the [[Response]] of the same context using
// the [[getStore]] function.
app.use(localStorage());
app.use((req, res, next) => {
req.locals.RAND = generateRandNumber();
});
function logger(message: string) {
const store = getStore();
if (store) {
// we've been called from inside async trap
// we can use the store content
const id = store.request.locals.RAND;
console.log(id, message);
} else {
console.log(null, message);
}
}
```
