fs-write-stream-atomic

Like fs.createWriteStream(...), but atomic.

Writes to a tmp file and does an atomic fs.rename to move it into place when it's done.

First rule of debugging: It's always a race condition.

USAGE

var fsWriteStreamAtomic = require('fs-write-stream-atomic') // options are optional. var write = fsWriteStreamAtomic('output.txt', options) var read = fs.createReadStream('input.txt') read.pipe(write) // When the write stream emits a 'finish' or 'close' event, // you can be sure that it is moved into place, and contains // all the bytes that were written to it, even if something else // was writing to `output.txt` at the same time.
