Package Exports
- write-file-atomic
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (write-file-atomic) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
write-file-atomic
This is an extension for node's fs.writeFile that makes its operation
atomic allows you to include uid/gid for the final file as well. It does
this by initially writing to a temporary file (your filename, followed by
".writeFile.atomic"), chowning it to the uid and gid you specified (if you
specified any) and finally renames it to your filename.
var writeFileAtomic = require('write-file-atomic')
writeFileAtomic(filename, data, [options], callback)
- filename String
- data String | Buffer
- options Object
- chown Object
- uid Number
- gid Number
- encoding String | Null default = 'utf8'
- mode Number default = 438 (aka 0666 in Octal) callback Function
- chown Object
Atomically and asynchronously writes data to a file, replacing the file if it already exists. data can be a string or a buffer.
If provided, the chown option requires both uid and gid properties or else you'll get an error.
The encoding option is ignored if data is a buffer. It defaults to 'utf8'.
Example:
fs.writeFile('message.txt', 'Hello Node', {chown:{uid:100,gid:50}}, function (err) {
if (err) throw err;
console.log('It\'s saved!');
});var writeFileAtomicSync = require('write-file-atomic').sync
writeFileAtomicSync(filename, data, [options])
The synchronous version of writeFileAtomic.
