App Development Without Coding Masterclass - Level 101

If a tutorial doesn't start with the Hello World, it must not be a serious one, right? Maybe not, but still, let's keep the tradition going and start our learning experience by saying "Hello Codeless World!". In this lecture you will learn:

• How to create a new page

• Add components to a page

• Set up data binding properties for the Input and Text components

• Use Codeless logic to set data model object properties

In this lecture, we explore the basics of database integration. You will build a basic app that retrieves data from the database and renders it in the user interface. To prepare your database, download the following file to your computer:

The video provides instructions for importing the data into your application. In this lecture, you will learn the following:

• How to import data into your Backendless database

• How to use the Container component

• How to configure the Container component to have the "Dynamic List Behavior"

• How to add the Text component to Container

• How to use data binding with the Text component's value

• How to retrieve data from the database

• How to set the retrieved database data as the data source for Container

• How to use sorting parameters in the database query

• How to retrieve related data objects and display them in the UI.

The "Playground page" is used throughout this course. It is a page containing layout and logic that helps us see how the program runs. It consists of two areas: the work area and the log output. There is a logic in the page that makes it easier for you to add logging message and see them right on the page. Additionally, in this lecture you will see and learn the following concepts:

• Creating a new page

• Setting up blocks on a page

• Using the "Flex grow" property to maximize the size of a block

• Adding a custom function with logic

• Using a custom Codeless function

In this lecture, we make some improvements to the "Playground page" to make it more developer-friendly

In this lecture, we explore the "mechanics" of working with string values in Codeless. You will learn the following:

• How to reference string values

• Available string operations in Codeless

• How to determine string size

• How to convert a string to the upper case value

In this lecture, we discuss what conditions are and how to use them in Codeless programming. We build a basic calculator application using the conditional (if/then/else) block. You will learn the following:

• How to use the if/do block in Codeless

• How to add "else if" elements to the "if/do" block

• How to return different values from different "if/else" parts of your logic

• How to perform string comparison

• How to perform a basic mathematical operation

In this lecture, we introduce the concept of "variables". You will learn:

• What variables are used for

• How to declare a variable

• How to rename a variable

• How to assign a value to a variable

• How to retrieve a value from a variable

• About variables' scope and lifespan

In this lecture, we review the approach for centering content. This includes both page's content as well as the content of an individual block.

This lecture describes two approaches for passing data from one page to another. You will build a basic app consisting of two pages. The first page retrieves data from the database and renders it in the user interface. When you make a selection of a data record, the second page opens up with the detailed information related to the selected record. This use-case is used to demonstrated available options for passing data between the pages. To prepare your database, download the following file to your computer:
