## Install
Install with [npm](https://www.npmjs.com/)

```
$ npm install tmp-file --save
```

or install using [yarn](https://yarnpkg.com)

```
$ yarn add tmp-file
```

## Usage
> For more use-cases see the [tests](test.js)

```js
const tmpFile = require('tmp-file')
```

## API

### [.generateFile](index.js#L38)
> 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.

**Params**

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

**Example**

```js
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'
```

### [.writeFile](index.js#L81)
> 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.

**Params**

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

**Example**

```js
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'
})
```

## Contributing
Pull requests and stars are always welcome. For bugs and feature requests, [please create an issue](https://github.com/tunnckoCore/tmp-file/issues/new).  
Please read the [contributing guidelines](CONTRIBUTING.md) 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 CodeMentor.io](https://www.codementor.io/tunnckocore?utm_source=github&utm_medium=button&utm_term=tunnckocore&utm_campaign=github) too.

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

1. Please DO NOT edit [README.md](README.md), [CHANGELOG.md](CHANGELOG.md) and [.verb.md](.verb.md) files. See ["Building docs"](#building-docs) section.
2. Ensure anything is okey by installing the dependencies and run the tests. See ["Running tests"](#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 [.verb.md](.verb.md)._

## Running tests
Clone repository and run the following in that cloned directory

```
$ npm install && npm test
```
