# execution-time-decorators

The `timer()` decorator starts a timer you can use to track how long an operation takes.
Suitable for use in both synchronous and asynchronous methods both in Node.js and Browser apps.

## Adding to your project

### In Node.js

Call require to get the instance:
```js
const { timer } = require('execution-time-decorators');
```

Or in ES6 and TS:
```typescript
import { timer } from 'execution-time-decorators';
```

## Usage
```typescript
class ExampleTimers {

@timer()
    readSync(filepath: string) {
        return fs.readFileSync(filepath);
    }

@timer()
    async readAsync(filepath: string) {
        return fs.promises.readFile(filepath);
    }

@timer({ logger: pino })
    async readAsyncP(filepath: string) {
        return fs.promises.readFile(filepath);
    }

@timer({ hr: true })
    static readSync(filepath: string) {
        return fs.readFileSync(filepath);
    }

@timer({ logger: pino, hr: true })
    static async readAsync(filepath: string) {
        return fs.promises.readFile(filepath);
    }

}
```

```console
[timer] [ExampleTimers::readSync]: begin
[timer] [ExampleTimers::readSync]: timer 0.008s

[timer] [ExampleTimers::readAsync]: begin
[timer] [ExampleTimers::readAsync]: timer 0.010s
