@parcel/fs-write-stream-atomic

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.

fsWriteStreamAtomic(filename, [options])

• filename {String} The file we want to write to
• options {Object}
  • chown {Object} User and group to set ownership after write
    • uid {Number}
    • gid {Number}
  • encoding {String} default = 'utf8'
  • mode {Number} default = 0666
  • flags {String} default = 'w'
