indie-catalog

This repo contains a web components catalog that you can host yourself. It's intended for companies that have private elements and would like to host them, but those elements can't be published to something like webcomponents.org.

Step 0. Clone this repo.

git clone https://github.com/PolymerLabs/indie-catalog.git
cd indie-catalog

Step 1. Configuration

The elements that you want to appear in the catalog are listed in catalog.json:

{
  "packages": {
    "an-element": { ... }
    "another-element": { ... }
  }
}

There's different setups you might be interested in:

Elements with an accessible git repo

If you want to access the code from a git repo, use the git field:

{
  "packages": {
    "paper-input": {
       "git": "https://github.com/polymerelements/paper-input",
       "description": "A Material Design input"
    }
  }
}

This assumes that your demo will be accessible in a demo subfolder of the git repo (i.e. paper-input/demo/index.html).

Elements with externally hosted the demo and docs

If the demo and docs are already hosted in a different place, you can use the docs and demo fields to link directly to them:

{
  "packages": {
    "paper-checkbox": {
      "description": "A Material Design checkbox with remote docs and demo",
      "demo": "https://raw-dot-custom-elements.appspot.com/PolymerElements/paper-checkbox/v2.0.0/paper-checkbox/demo/index.html",
      "docs": "https://www.webcomponents.org/element/PolymerElements/paper-checkbox"
    }
  }
}

You can also use these properties this if your element has a demo not in a /demo subdirectory, but in some different directory, by using relative paths. This relative path should look like dist/{element-name}/bower_components/{element-name}/...

"lazy-image": {
  "git": "https://github.com/notwaldorf/lazy-image",
  "description": "A custom image element that lets you load resources on demand",
  "demo": "dist/lazy-image/bower_components/lazy-image/index.html"    
}

Assumptions

For either usage, the following extra assumptions are made:

  • running bower install in that repo completes successfully
  • your element is written using relative paths for the elements it depends on, rather than using bower_components anywhere. See PolymerElements/paper-button for an example.

Step 2. Do the build dance.

This should take a while:

npm install
npm run build

If you're curious, this will be doing the following steps, for each package in catalog.json with a git repo provided:

  • git clone it to /dist
  • remove the .git and .gitignore dirs from the clone
  • bower install in /dist/${elementName}/bower_components
  • copy the git clone into /dist/${elementName}/bower_components/${elementName}, so that the demo works.

Step 3. Run it locally

python -m SimpleHTTPServer # or your favourite local server
