> Get normalized repository from package json data


## Synopsis

People write different formats of repository url in package.json and sometimes there is even a typo.

This module extracts the code from [npm/repo](https://github.com/npm/npm/blob/master/lib/repo.js), and uses [normalize-package-data](https://github.com/npm/normalize-package-data), [hosted-git-info](https://github.com/npm/hosted-git-info) and [parse-github-repo-url](https://github.com/repo-utils/parse-github-repo-url) to parse data. Please check them out for more details.

**This module can fix some common [typos](typos.json).**

**If you find your normalized repository is not correct, It's most likely the underlying deps' problem. Please try to triage the problem before you open an issue here.**


## Install

```sh
$ npm install --save get-pkg-repo
```


## Usage

```js
var fs = require('fs');
var getPkgRepo = require('get-pkg-repo');

fs.readFile('package.json', function(err, pkgData) {
  if (err) {
    ...
  }

  var repo = getPkgRepo(pkgData);
  console.log(repo)
  /*=>

    protocols_re: /^(git|http|git\+ssh|git\+https|ssh|https):$/,

    auth: null,
    project: 'get-pkg-repo',
    committish: null,
    default: 'https' }
  */
})
```


## API

getPkgRepo(pkgData, [fixTypo])

Returns a hosted-git-info returned object if it matches a git host. If not returns a `url.parse` object with a `browse` function which returns the url that can be browsed.

### pkgData

Type: `object` or `json`

Package.json data

### fixTypo

Type: `boolean`

If you want to fix your typical typos automatically, pass true. See [the list of predefined typos](typos.json).


## CLI

```sh
$ npm install --global get-pkg-repo
```

You can use cli to see what your url will look like after being parsed.

You can enter interactive mode by typing

```sh
$ get-pkg-repo
https://github.com/stevemao/get-pkg-repo
{ type: 'github',
  protocols: [ 'git', 'http', 'git+ssh', 'git+https', 'ssh', 'https' ],
  domain: 'github.com',
  treepath: 'tree',
  filetemplate: 'https://{auth@}raw.githubusercontent.com/{user}/{project}/{committish}/{path}',
  bugstemplate: 'https://{domain}/{user}/{project}/issues',
  gittemplate: 'git://{auth@}{domain}/{user}/{project}.git{#committish}',
  sshtemplate: 'git@{domain}:{user}/{project}.git{#committish}',
  sshurltemplate: 'git+ssh://git@{domain}/{user}/{project}.git{#committish}',
  browsetemplate: 'https://{domain}/{user}/{project}{/tree/committish}',
  docstemplate: 'https://{domain}/{user}/{project}{/tree/committish}#readme',
  httpstemplate: 'git+https://{auth@}{domain}/{user}/{project}.git{#committish}',
  shortcuttemplate: '{type}:{user}/{project}{#committish}',
  pathtemplate: '{user}/{project}{#committish}',
  pathmatch: /^[\/]([^\/]+)[\/]([^\/]+?)(?:[.]git)?$/,
  protocols_re: /^(git|http|git\+ssh|git\+https|ssh|https):$/,
  user: 'stevemao',
  auth: null,
  project: 'get-pkg-repo',
  committish: null,
  default: 'https' }
```

You can also validate the repository url in your package.json by using the command followed by a package.json path. You can specify more than one path at a time.

```sh
$ get-pkg-repo package.json
{ type: 'github',
  protocols: [ 'git', 'http', 'git+ssh', 'git+https', 'ssh', 'https' ],
...
# or
$ cat package.json | get-pkg-repo --fix-typo
{ type: 'github',
  protocols: [ 'git', 'http', 'git+ssh', 'git+https', 'ssh', 'https' ],
...
```
