# Deno FastWriter ✒

Fast & Safe file writing for [Deno](https://deno.land/)!

This utility has no dependencies, and is made to speed up overwriting the same file. It writes the last provided data only when previous data has been written. Also, the writing is **atomic**, so main file will not be corrupted in case of an emergency process exiting.

> This library is heavily inspired by [steno](https://github.com/typicode/steno) made by [typicode](https://github.com/typicode). FastWriter uses same optimization techniques, but made specifically for Deno.




## Example

```typescript

import { FastWriter } from 'https://deno.land/x/fastwriter/mod.ts'

// Initialize writer

const writer = new FastWriter('./my-file.txt');

// Write data using this method

writer.write('Super-fast writing!');

```
