<iron-component-page>
iron-component-page is a full-page documentation browser for custom elements, mixins, classes, and more. It consumes the JSON descriptor format produced by Polymer Analyzer.
See: Documentation, Demo.
You may also be interested in the iron-doc-* element collection which underlies this element and can be used to embed documentation in other apps (for example, webcomponents.org does this).
Usage
Documenting your element
iron-component-page is designed to make it easy to view documentation for your custom element project.
-
Install the Polymer CLI with
npm install -g polymer-cli. This gives you a command-line interface to Polymer Analyzer (among other things). -
cdto your project directory. This can be a custom element, a full app, or even a plain JavaScript library. Polymer Analyzer will discover all of the interesting items recursively in your project directory. -
Analyze your project with
polymer analyze > analysis.json. This produces a JSON descriptor file. By defaultiron-component-pagewill look for a file calledanalysis.json(you can override this with thedescriptor-urlproperty). -
Add
iron-component-pageas a dev dependency of your project:npm install @polymer/iron-component-page --save-dev. -
Create an HTML file to instantiate an
iron-component-pageelement (e.g.index.htmlordocs.html). Note that you may need to adjust your import paths depending on your project layout:
<!doctype html>
<html>
<head>
<script type="module">
import '@polymer/iron-component-page/iron-component-page.js';
</script>
</head>
<body>
<iron-component-page></iron-component-page>
</body>
</html>
- Serve that page using
polymer serve --npm.
Routing
iron-component-page handles URL routing (via iron-doc-viewer) to provide permanent addresses for all locations in the documentation tree, including scroll anchor targets.
By default it uses the URL fragment for routing (e.g. docs.html#/elements/my-element#property-foo), in order to support simple static file hosts.
To use the real URL path for routing, set the base-href property to the server mount point (e.g. /api/docs or empty string for the root path). Note that this requires a host that serves the application from all paths that should be handled by the doc viewer.
Styling
iron-component-page uses the default theme from iron-doc-viewer. See its documentation for styling. The following custom properties and mixins are also available:
| Custom property | Description | Default |
|---|---|---|
--iron-component-page-header-color |
Background color of main header. | paper-pink-600 |
