| <h2 class="ui header">The UserALE.js API</h2> |
| <p><a href="https://github.com/apache/incubator-flagon-useralejs">Apache UserALE.js</a> features a robust API that allows you |
| customize official Apache Flagon UserALE.js <a href="https://github.com/apache/incubator-flagon-useralejs/tree/master/build">builds</a> page-by-page to suite your needs.</p> |
| |
| <p>The API exposes a number of functions, including: <code class="highlighter-rouge">options</code>, <code class="highlighter-rouge">setLogFilter</code>, & <code class="highlighter-rouge">setLogMapper</code>. With these two powerful functions, you have a lot of |
| latitude in customizing and curating your logs.</p> |
| |
| <h1 id="api-usage">API Usage</h1> |
| |
| <p>To invoke the API, simply add additional javascript code blocks under your UserALE.js script tag.</p> |
| |
| <p>Don’t forget to add UserALE.js to your project!</p> |
| |
| <p>It can be deployed as either script-tag, NPM module, or via CDN! For in-depth example, see our <a href="/docs/useralejs">Getting Started Guide</a>) or source <a href="https://github.com/apache/incubator-flagon-useralejs#usage">README.md</a>.</p> |
| |
| <p>Also, check out our<a href="https://github.com/apache/incubator-flagon-useralejs/tree/master/example">example test utility</a> so that you can experiment with logs in your terminal!</p> |
| |
| <p>The following API examples use script-tag deployment methods for illustration:</p> |
| |
| <div class="language-html highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="nt"><head></span> |
| <span class="nt"><title></span>UserAleJS - Example Page<span class="nt"></title></span> |

| </code></pre></div></div> |
| |
| <h2 id="options-examples"><code class="highlighter-rouge">options</code> Examples</h2> |
| |
| <p><code class="highlighter-rouge">options</code> allows you to modify UserALE.js script tag parameters. This can be particularly useful if need to pass additional data about users from your page into the logging parameters, like username and sessionID. You can build variables constructors that pass data from form data or browser storage to UserALE’s paramters.</p> |
| |
| <div class="language-html highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"><!-- |

| <p>You can also use the <code class="highlighter-rouge">setLogFilter</code> function to do other cool stuff. Below is an example for how to further modify the |

| <ul> |
| <li>No need to dig into our source code</li> |
| <li>Version control is easy and no need to sweat merges–just download the latest <a href="/releases">release</a>, |
| or update via <a href="https://www.npmjs.com/package/flagon-userale">npm</a>.</li> |
| <li>Manage logs page-by-page, ideal for large or complex sites</li> |
| <li>Use basic or best-practice JS styles and methods to build your own filters, no need to learn weird custom syntax.</li> |
| </ul> |

| Apache Flagon is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF. |
