Course Outline1:13
The Birth of OWL Framework: What is OWL and Why OWL2:42
Introduce the OWL framework, its purpose, and why it was created. Explain its small size, TypeScript implementation, XML-based rendering, and browser-based toolchain options for outside or inside Odoo.
Understanding OWL Framework Architecture3:57
Getting The Most Out of This Course2:37
Watch at your own pace with video controls, pause, and rewind, code along with provided resources, and repeat concepts.

Standard QWeb Directives plus OWL Directives3:30
Explore qweb templates in Odoo, the xml-based templating engine that renders a virtual dom of HTML through compiled functions. Master t directives like t-escape, t-if, t-for-each, and dynamic t attributes.
Outputting Data using t-esc, t-out2:38
How to Set Variables with the Template: t-set, t-value1:09
Learn how to declare and use template variables with t-set and t-value in Qweb, perform rendering-time computations like 2 + 5, and reuse the variable bar throughout the view.
How to use Conditional Directives: t-if, t-elif, t-else2:20
Master conditional directives in Odoo OWL templates using t-if, t-elif, and t-else to render age-based messages, handling undeclared age and the exact 18 case with clear end of if syntax.
How to Loop in Owl Template t-foreach3:39
Dynamic Attributes in Owl Template: t-tag, t-att-class, t-att5:08
QWeb Translations (t-translation), Debugging (t-log) and Restrictions (block-)7:03
Explore QWeb translations (t-translation), debugging (t-log), and restrictions (block-). Learn how to set up a translations object, the translate function, and translatable attributes for templates.
Sub Template, Dynamic Sub Template with t-call4:08
Explore reusing templates in owl by defining sub templates with t-name and a main template, then render them dynamically using t-call, t-set, and interpolation.

Understanding OWL Component Lifecycles and its Hooks5:15
We will explore the lifecycle hooks like: setup, willStart, willRender, rendered, mounted, onWillUpdateProps, onWillPatch, onPatched, onWillUnmount, onWillDestroy and onError.
OWL Component Lifecycles in Action - A Short Demo9:56
Other Hooks: useState, useRef, useEffect, useComponent, useExternalListener8:43
Explore OWL hooks such as useState, useRef, and useEffect to build reactive components, manage inputs, and fetch data with dependency-driven updates, plus custom hooks like use component.
Sub Components and Dynamic Sub Components (Task: Track Mouse Position)4:57
