A simple temporary file and directory creator for node.js.
The main difference between bruce's node-temp is that mine more
aggressively checks for the existence of the newly created temporary file and
creates the new file with O_EXCL
instead of simple O_CREAT | O_RDRW
, so it
is safer.
The API is slightly different as well, Tmp does not yet provide synchronous calls and all the parameters are optional.
You can set whether you want to remove the temporary file on process exit or not, and the destination directory can also be set.
npm install tmp
Simple temporary file creation, the file will be unlinked on process exit.
var tmp = require('tmp');
tmp.file(function _tempFileCreated(err, path, fd) {
if (err) throw err;
console.log("File: ", path);
console.log("Filedescriptor: ", fd);
});
Simple temporary directory creation, it will be removed on process exit.
If the directory still contains items on process exit, then it won't be removed.
var tmp = require('tmp');
tmp.dir(function _tempDirCreated(err, path) {
if (err) throw err;
console.log("Dir: ", path);
});
Creates a file with mode 0644
, prefix will be prefix-
and postfix will be .txt
.
var tmp = require('tmp');
tmp.file({ mode: 0644, prefix: 'prefix-', postfix: '.txt' }, function _tempFileCreated(err, path, fd) {
if (err) throw err;
console.log("File: ", path);
console.log("Filedescriptor: ", fd);
});
Creates a directory with mode 0755
, prefix will be myTmpDir_
.
var tmp = require('tmp');
tmp.dir({ mode: 0750, prefix: 'myTmpDir_' }, function _tempDirCreated(err, path) {
if (err) throw err;
console.log("Dir: ", path);
});
Creates a new temporary directory with mode 0700
and filename like /tmp/tmp-nk2J1u
.
var tmp = require('tmp');
tmp.dir({ template: '/tmp/tmp-XXXXXX' }, function _tempDirCreated(err, path) {
if (err) throw err;
console.log("Dir: ", path);
});
All options are optional :)
mode
: the file mode to create with it fallbacks to0600
on file creation and0700
on directory creationprefix
: the optional prefix, fallbacks totmp-
if not providedpostfix
: the optional postfix, fallbacks to.tmp
on file creationtemplate
:mkstemps
like filename template, no defaultdir
: the optional temporary directory, fallbacks to system default (guesses from environment)tries
: how many times should the function tries to get a unique filename before giving up, default3
keep
: signals that the temporary file or directory should not be deleted on exit, default is to delete
