fs-write-stream-atomic
Advanced tools
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.
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.
