WebJS

WebJS is a framework for buiding standard multipage web applications.

Installation Using CDN

Step 1) Create a file config.js

var APP_ID = "";      // Your APP unique ID (optional)
var WEBSITE_URL = ""; // Your website root URL
var API_URL = "";     // Your website API URL (optional)
if (location.hostname === "localhost" || location.hostname === "127.0.0.1" || location.hostname === "") {
    WEBSITE_URL = window.location.protocol + '//' + window.location.hostname + ':' + window.location.port;
}

Step 2) Add to your webpage

<script src="config.js"></script>
<script src="https://cdn.jsdelivr.net/gh/lesichkovm/web@2.7.0/bin/web.js"></script>

Manual Installation

Step 1) Create a file config.js

var APP_ID = "";      // Your APP unique ID
var WEBSITE_URL = ""; // Your website root URL
var API_URL = "";     // Your website API URL
if (location.hostname === "localhost" || location.hostname === "127.0.0.1" || location.hostname === "") {
    WEBSITE_URL = window.location.protocol + '//' + window.location.hostname + ':' + window.location.port;
}

Step 2) Download the web.js library locally and add to your webpage

<script src="config.js"></script>
<script src="web.js"></script>

Hint: Alternatively you may want to download automatically using Gulp

gulp.task('web', function (done) {
    var url = "https://cdn.jsdelivr.net/gh/lesichkovm/web@latest/bin/web.js";

    download(url)
        .pipe(gulp.dest("js/"));

    done();
});

Hint: Advanced optional. You may want to group config.js with web.js to reduce the number of the HTTP calls.
