					// Apply
					this.stat = null
					this.close('deleted')

Safe FS

Stop getting EMFILE errors! Open only as many files as the operating system supports.

Usage

Complete API Documentation.

var safefs = require('safefs')

SafeFS uses graceful-fs to wrap all of the standard file system methods to avoid EMFILE errors among other problems.

On-top of graceful-fs, SafeFS also adds additional wrapping on the following methods:

• writeFile(path, data, options?, next) - ensure the full path exists before writing to it
• appendFile(path, data, options?, next) - ensure the full path exists before writing to it
• mkdir(path, mode?, next) - mode defaults to 0o777 & (~process.umask())
• unlink(path, next) - checks if the file exists before removing it

SafeFS also define these additional methods:

• ensurePath(path, options, next) - ensure the full path exists, equivalent to unix's mdir -p path
• getParentPathSync(path) - returns the parent directory of the path

Alternatives

You should use these instead, which use and provide modern APIs while providing brilliant ecosystem support:

• @bevry/fs-accessible
• @bevry/fs-executable
• @bevry/fs-list
• @bevry/fs-mkdirp
• @bevry/fs-read
• @bevry/fs-readable
• @bevry/fs-remove
• @bevry/fs-rmdir
• @bevry/fs-unlink
• @bevry/fs-write
• @bevry/fs-writable
