Atomic-file-rw
This module is meant as a replacement for atomic-file as it has better error handling on node and is faster in the browser.
The library is written to handle writing to a few number of files in a
safe manner. Concurrent writes to the same file are completed in the
order they are started. A temporary file with the same filename as the
original — with a suffix ~ — is employed to ensure atomicity.
Example
Write a buffer to file and read it again:
const atomic = require('atomic-file-rw')
atomic.writeFile("test.txt", Buffer.from('GREETINGS'), (err, x) => {
atomic.readFile("test.txt", (err, buf) => {
console.log(buf.toString())
})
})API
atomic.readFile(path[, options], callback)
Same arguments as Node.js's fs.readFile, but in the browser the
options is ignored.
atomic.writeFile(file, data[, options], callback)
Same arguments as Node.js's fs.writeFile, but in the browser the
options is ignored.
atomic.deleteFile(file, callback)
Same arguments as Node.js's fs.unlink.
