clean-write

Cleanup corrupted files on write errors.

When an exception is thrown while a file is being written, that file will be corrupted. The same problem occurs when the process exits unexpectedly (for example with CTRL-C).

This library removes corrupted files in such cases.

Example

const cleanWrite = require('clean-write')

const { writeFile } = require('fs')
const { promisify } = require('util')
const writeFileAsync = promisify(writeFile)

const filePath = './path/to/file.js'
const writeFunction = async function() {
  await writeFileAsync(filePath, 'example')
}

// If an exception happens or if the program exits, the file will be removed
await cleanWrite(writeFunction, filePath)

Install

npm install clean-write

Usage

cleanWrite(writeFunction, filePath)

writeFunction: () => Promise<void>
filePath: string
Returns: Promise<void>

The file is removed if either:

• writeFunction() throws an exception or returns a rejected Promise
• the process exits before writeFunction() completes
