I created my app using the sencha create app command. It is working locally

  • 0

I created my app using the sencha create app command. It is working locally on my machine as well on our web server. I am trying to build the app for production but the following command is not working for me:

sencha app build production

I’m not getting any error messages or output whatsoever. Nothing in the directory changes.

The following command:

sencha build -p appname.jsb3 -v -d .

generates the jsb3 file. However, my index.html is never updated to load the new files. According to the information I have found online, my index.html should be updated to point to the new files.

I think I am missing something somewhere but I can’t find any tutorials online that work for me. Can anyone point me in the right direction? My index.html is pasted below if that helps to determine what I’m doing wrong.

    Try this:

    // first open cmd and run:

    cd path/to/application

    // then make sure index.html exists in you path/to/application:

    <!DOCTYPE html>
<html>
<head>
 <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
 <title>title</title>
 <!-- update this to your css file -->
 <link rel="stylesheet" href="resources/css/app.css" type="text/css">
 <!-- you can get this file from sencha original files -->
 <script type="text/javascript" src="sdk/sencha-touch-debug.js"></script>
 <script type="text/javascript" src="app.js"></script> 
</head>
<body></body>
</html>

    // make sure the file is loading your application and then run the command:

    sencha create jsb -a index.html -p app.jsb3

    // also execute the 2nd command. note the DOT at the end should be added to the command:

    sencha build -p app.jsb3 -d .

    // now our application is built:

    Create new html file “built.html” and use the below code:

    <!DOCTYPE html>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>title</title>
    <link rel="stylesheet" href="resources/css/app.css" type="text/css">
    <script type="text/javascript" src="sdk/sencha-touch.js"></script>
    <script type="text/javascript" src="all-classes.js"></script>
    <script type="text/javascript" src="app.js"></script>
</head>
<body></body>
</html>

    // now open built.html
