writeFileAtomic(filename, data, [options], [callback]) + +* filename **String** +* data **String** | **Buffer** +* options **Object** | **String** + * chown **Object** default, uid & gid of existing file, if any + * uid **Number** + * gid **Number** + * encoding **String** | **Null** default = 'utf8' + * fsync **Boolean** default = true + * mode **Number** default, from existing file, if any + * tmpfileCreated **Function** called when the tmpfile is created +* callback **Function** + +Atomically and asynchronously writes data to a file, replacing the file if it already +exists. data can be a string or a buffer. + +The file is initially named `filename + "." + murmurhex(__filename, process.pid, ++invocations)`. +Note that `require('worker_threads').threadId` is used in addition to `process.pid` if running inside of a worker thread. +If writeFile completes successfully then, if passed the **chown** option it will change +the ownership of the file. Finally it renames the file back to the filename you specified. If +it encounters errors at any of these steps it will attempt to unlink the temporary file and then +pass the error back to the caller. +If multiple writes are concurrently issued to the same file, the write operations are put into a queue and serialized in the order they were called, using Promises. Writes to different files are still executed in parallel. + +If provided, the **chown** option requires both **uid** and **gid** properties or else +you'll get an error. If **chown** is not specified it will default to using +the owner of the previous file. To prevent chown from being ran you can +also pass `false`, in which case the file will be created with the current user's credentials. + +If **mode** is not specified, it will default to using the permissions from +an existing file, if any. Expicitly setting this to `false` remove this default, resulting +in a file created with the system default permissions. + +If options is a String, it's assumed to be the **encoding** option. The **encoding** option is ignored if **data** is a buffer. It defaults to 'utf8'. + +If the **fsync** option is **false**, writeFile will skip the final fsync call. + +If the **tmpfileCreated** option is specified it will be called with the name of the tmpfile when created. + +Example: + +```javascript +writeFileAtomic('message.txt', 'Hello Node', {chown:{uid:100,gid:50}}, function (err) { + if (err) throw err; + console.log('It\'s saved!'); +}); +``` + +This function also supports async/await: + +```javascript +(async () => { + try { + await writeFileAtomic('message.txt', 'Hello Node', {chown:{uid:100,gid:50}}); + console.log('It\'s saved!'); + } catch (err) { + console.error(err); + process.exit(1); + } +})(); +``` + +### var writeFileAtomicSync = require('write-file-atomic').sync
