esriuk.github.io

Landing page for Esri UK open source tools and apps, and presentation resources.

Configuration

Page content is configured using a JavaScript object set with config.js. This controls:

• Page title, description, tagline (both in the banner and metadata)
• The GitHub organisation
• The sections shown, including:
  • icons, titles, descriptions
  • the number of repositories to show and topic(s) to filter by
  • The featured item to show for each section

The sections will alternate between a dark and light theme. The sections will include a number of cards representing repositories up to the configured maxRepos which are loaded from the GitHub Search API. Should the API's rate limit be reached, these cards will be omitted.

The page is highly tolerant of faults in the configuration and will accommodate missing fields either by omitting content or falling back to default values (in the case of the page title and GitHub organisation). Should no config.js file be present or an error be present within it, the page will default to showing a single section entitled "Repositories" containing up to eight recently updated repositories.

The sticky anchor navigation will be present when the viewport is wide enough and when more than one section is present. Sections will be included provided that they are configured with both a title and anchor (id).

A static "lite" version of the Esri UK global navigation, as present on esriuk.com is present.

Editing

The landing page (index.html) uses JavaScript template literals as a HTML templating system. This is used within script tags which remove themselves once ran. Two functions, template and templateIfElse, are available to help with this. For example:

• Using templateIfElse to display content from config.js with a fall back if that it is not defined

    <script id="template">templateIfElse(config.title, `
    <h1>${config.title}</h1>
    `, `
    <h1>Hello world</h1>
    `);
    </script>

• Alternatively, conditionally display content and removing the script without the use of the helper functions

    <script id="template">
    var content = `
        ${config.description ? `<p>${config.description}</p>` : ""}
    `;
    document.querySelector("script#template").outerHTML = content;
    </script>

Most styles are contained within head.css and calcite-web is available to use. The styles for the header and footer navigations are within global-nav-lite.css. Supporting JavaScript is contained within foot.js and handles loading of content from the GitHub Search API and dynamic stylesheet generation. There are placeholders in index.html for potential head.js and foot.css files.

To edit simply fork and clone the project, or edit the files directly on github.com. No dependencies or build processes are required.
