This project represents the Apache Camel UI theme that is used in the Apache Camel website documentation site. The website is generated with Antora and this is the UI theme for that.
If you want to use this UI theme in your Antora-generated site, add the following UI configuration to your playbook:
ui:
bundle:
url: https://github.com/apache/camel-website/releases/download/{current-release}/ui-bundle.zip
snapshot: true|
Note
|
The snapshot flag tells Antora to fetch the UI when the --fetch command-line flag is present.
This setting is required because updates to the UI bundle are pushed to the same URL.
If the URL were to be unique, this setting would not be required.
|
Read on to learn how to customize the default UI for your own documentation.
This section offers a basic tutorial to teach you how to set up the default UI project, preview it locally, and bundle it for use with Antora. A more comprehensive can be found in the documentation at {url-antora-docs}.
To preview and bundle the UI, you need the following software on your computer:
First, make sure you have git installed.
$ git --version
If not, download and install the git package for your system.
Next, make sure that you have Node.js installed.
$ node --version
If this command fails with an error, you don’t have Node.js installed. If the command doesn’t report an LTS version of Node.js (e.g., v10.15.3), it means you don’t have a suitable version of Node.js installed. In this guide, we’ll be installing Node.js 10.
While you can install Node.js from the official packages, we strongly recommend that you use nvm (Node Version Manager) to manage your Node.js installation(s). Follow the nvm installation instructions to set up nvm on your machine.
Once you’ve installed nvm, open a new terminal and install Node.js 10 using the following command:
$ nvm install 10
You can switch to this version of Node.js at any time using the following command:
$ nvm use 10
To make Node.js 10 the default in new terminals, type:
$ nvm alias default 10
Now that you have Node.js installed, you can proceed with installing the Gulp CLI.
Finally, you’ll need Yarn, which is the preferred package manager for the Node ecosystem.
Follow the documentation on installing Yarn for your Operating system.
Now that you have the prerequisites installed, you can fetch and build the Apache Camel UI project.
Clone the Camel UI project using git:
$ git clone https://github.com/apache/camel-website && cd camel-website/antora-ui-camel
The example above clones the Apache Camel Website project and then switches to the UI project folder on your filesystem. Stay in this project folder when executing all subsequent commands.
Use Yarn to install the project’s dependencies. In your terminal, execute the following command:
$ yarn install
The default UI project is configured to preview offline. The files in the preview-src/ folder provide the sample content that allow you to see the UI in action. In this folder, you’ll primarily find pages written in AsciiDoc. These pages provide a representative sample and kitchen sink of content from the real site.
To build the UI and preview it in a local web server, run the preview command:
$ yarn preview
You’ll see a URL listed in the output of this command:
[12:00:00] Starting server... [12:00:00] Server started http://localhost:5252 [12:00:00] Running server
Navigate to this URL to preview the site locally.
While this command is running, any changes you make to the source files will be instantly reflected in the browser.
This works by monitoring the project for changes, running the preview:build task if a change is detected, and sending the updates to the browser.
Press Ctrl+C to stop the preview server and end the continuous build.
If you need to package the UI so you can use it to generate the documentation site locally, run the following command:
$ yarn build
If any errors are reported by lint, you’ll need to fix them.
When the command completes successfully, the UI bundle will be available at build/ui-bundle.zip.
You can point Antora at this bundle using the --ui-bundle-url command-line option.
If you have the preview running, and you want to bundle without causing the preview to be clobbered, use:
$ gulp bundle:pack
The UI bundle will again be available at build/ui-bundle.zip.
