bower-alternative-source-resolver

An extension to bower allowing alternative component repositories. This component solves issues with the shorthand_resolver in bower, because you can only target one resolver. This allows you to target different owners and re-write the URL to avoid using the shorthand_resolver.

Preparation

This repository augments bower.

npm install -g bower

Installation

In your project, install bower-alternative-source-resolver locally. It can be installed globally too.

npm install --save-dev bower-alternative-source-resolver

Edit a .bowerrc (which can be hosted at /, ~, or in any parent directory for your project) and add the resolver.

{
    "resolvers": [
      "bower-alternative-source-resolver"
    ]
}

Configuration

Add alternative sources to load from by adding an alternativeSources key to either your .bowerrc or bower.json object. The .bowerrc takes precendence, the arrays are not merged.

{
  "alternateSources": [
    {
      "owner": "my_components",
      "url": "https://internal.bitbucket.com/${owner}/${package}.git${version}"
    }
  ]
}

To re-write URI's you can use rewriteSources. There are three parts:

1. match to find a URI to re-write (uses indexOf)
2. parse to find parts in the URI to pull out for re-framing (uses new RegExp)
3. rewrite to write the new form of the URI (uses _.template at v4.x.x)

The parts you match with the RegExp map to variables _# in the template for rewrite

{
  "rewriteSources": [
    {
      "match": "ssh",
      "parse": "group\\/(.*?)\\.",
      "rewrite": "group/${ _1 }"
    }
  ]
}

Usage

In your bower file or when using bower install the owner keys will match the owner portion of any shorthand bower URL's and re-write with the template provided in the associated url attribute.

{
  "dependencies": {
    "button": "my_components/button#1.2.3"
  }
}

If you type bower install for your project with this configuration the request to "my_components/button#1.2.3" will be re-written to "https://internal.bitbucket.com/my_components/button.git1.2.3" because the owner matched.
