It consumes the JSON descriptor format produced by [Polymer Analyzer](https://github.com/Polymer/polymer-analyzer). See: [Documentation](https://www.webcomponents.org/element/@polymer/iron-component-page), [Demo](https://www.webcomponents.org/element/@polymer/iron-component-page/demo/demo/index.html). You may also be interested in the [`iron-doc-*`](https://github.com/PolymerElements/iron-doc-viewer) element collection which underlies this element and can be used to embed documentation in other apps (for example, [webcomponents.org](https://www.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. 1. Install the [Polymer CLI](https://github.com/Polymer/tools/tree/master/packages/cli) with `npm install -g polymer-cli`. This gives you a command-line interface to Polymer Analyzer (among other things). 2. `cd` to 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. 3. Analyze your project with `polymer analyze > analysis.json`. This produces a JSON descriptor file. By default `iron-component-page` will look for a file called `analysis.json` (you can override this with the `descriptor-url` property). 4. Add `iron-component-page` as a dev dependency of your project: `npm install @polymer/iron-component-page --save-dev`. 5. Create an HTML file to instantiate an `iron-component-page` element (e.g. `index.html` or `docs.html`). Note that you may need to adjust your import paths depending on your project layout: ```html ``` 6. 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`](https://github.com/PolymerElements/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` ## Contributing If you want to send a PR to this element, here are the instructions for running the tests and demo locally: ### Installation ```sh git clone https://github.com/PolymerElements/iron-component-page cd iron-component-page npm install npm install -g polymer-cli ``` ### Running the demo locally ```sh polymer serve --npm open http://127.0.0.1:/demo/ ``` ### Running the tests ```sh polymer test --npm ```
