For more use-cases see the tests

const tmpFile = require('tmp-file')



Generates a "file" object with path and contents properties without writing to disk. Where file.path will be random string to OS tmp folder, using tmp-filepath. And file.contents will be the passed contents or empty string.


  • [contents] {String|Buffer}: completely optional, string or buffer passed to fs.writeFile
  • returns {Object}: plain file object


const tmp = require('tmp-file')
const file = tmp.generateFile('foo bar contents')
console.log(file.path) // => '/tmp/cia0ervrm0000vppvw0t61v9m'
console.log(file.contents) // => 'foo bar contents'


Write a temporary file to disk on OS tmp folder. It generates a file object using .generateFile method which in turn uses tmp-filepath to generate random filepath to tmp folder.

Note: This function is exported as module.exports, exports.default and exports.writeFile. If you don't understand what we are talking about, just see the example below.


  • [contents] {String|Buffer}: completely optional, string or buffer, passed to fs.writeFile
  • returns {Promise}: resolved promise with file object


const tmpFile = require('tmp-file')
// or
// const tmpFile = require('tmp-file').default
// or
// const tmpFile = require('tmp-file').writeFile
tmpFile('quxie pixie').then((file) => {
  console.log(file.path) // => '/tmp/da4sd0e534d0vppvw0t61v9m'
  console.log(file.contents) // => 'quxie pixie'

Pull requests and stars are always welcome. For bugs and feature requests, please create an issue.
Please read the contributing guidelines for advice on opening issues, pull requests, and coding standards.
If you need some help and can spent some cash, feel free to contact me at too.

In short: If you want to contribute to that project, please follow these things

  1. Please DO NOT edit, and files. See "Building docs" section.
  2. Ensure anything is okey by installing the dependencies and run the tests. See "Running tests" section.
  3. Always use npm run commit to commit changes instead of git commit, because it is interactive and user-friendly. It uses commitizen behind the scenes, which follows Conventional Changelog idealogy.
  4. Do NOT bump the version in package.json. For that we use npm run release, which is standard-version and follows Conventional Changelog idealogy.

Thanks a lot! :)

Building docs

Documentation and that readme is generated using verb-generate-readme, which is a verb generator, so you need to install both of them and then run verb command like that

$ npm install verbose/verb#dev verb-generate-readme --global && verb

Please don't edit the README directly. Any changes to the readme must be made in

Running tests

Clone repository and run the following in that cloned directory
