file-writer

Description

file-writer provides methods for easy fire-and-forget file operations.

It prevents race conditions on multiple write operations for the same filename. It schedules a write operation, if it is requested before the previous one has finished.

Installation

npm install "@popovmp/file-writer"

Usage

import {appendAndForget, writeAndForget} from "@popovmp/file-writer";

writeAndForget("example.txt", "Some text\n");
appendAndForget("example.txt", "Another text\n");

It safely writes the following content to example.txt:

import {appendAndForget} from "@popovmp/file-writer";

for (let i = 0; i < 1000; i++) {
    appendAndForget("example.txt", `Line ${i}\n`);
}

It throws NodeJS.ErrnoException.
