This post aims to collect related resources (video tutorials, documents, code examples, etc.) for HarmonyOS application development based on the HarmonyOS application development process. If it helps you, please give me a thumbs up!
This post will continue to be updated~
If your learning goal is a preliminary understanding of HarmonyOS (system positioning, architecture, features, opportunities, etc.), you can consult the following resources:
| Resource Name | Resource link | Resource source |
| HarmonyOS overview | https://developer.harmonyos.com/cn/docs/documentation/doc-guides/harmonyos-overview-0000000000011903 | Official document |

| Can HarmonyOS work? | https://edu.51cto.com/course/25048.html?hm | 51CTO->HarmonyOS Technical Community Video tutorial |
For developers who are starting to develop Hongmeng applications for the first time, they need to understand the basic concepts and development process of Hongmeng application development, and quickly run through a helloworld or simple example. You can consult the following resources:
| Resource Name | Resource link | Resource source |

Ability is an important part of the HarmonyOS application, divided into two types: FA (Feature Ability) and PA (Particle Ability).
FA supports Page Ability: Page template is the only template supported by FA to provide the ability to interact with users.
PA supports Service Ability and Data Ability: Service templates are used to provide the ability to run tasks in the background; Data templates are used to provide a unified data access abstraction to the outside.
To develop HarmonyOS applications, you must first learn how to use Ability. The resources you can consult are:

JS UI针对智慧屏（TV）和智能穿戴（Wearable）、轻量级智能穿戴（Lite Wearable）的资源要进行以下区分：
在进行智慧屏（TV）和智能穿戴（Wearable）应用开发时，JS UI只是用于FA开发，PA（Service Ability和Data Ability）的开发仍旧使用Java语言。JS UI可以查阅的资源有：
| 资源名称 | 资源链接 | 资源来源 |
| JS UI框架 | https://developer.harmonyos.com/cn/docs/documentation/doc-guides/ui-js-overview-0000000000500376 | 官方文档 |
| JS API参考-智慧屏和智能穿戴开发 | https://developer.harmonyos.com/cn/docs/documentation/doc-references/js-framework-file-0000000000611396 | 官方文档 |
轻量级智能穿戴（Lite Wearable）应用相对轻量化，现阶段只使用JS语言进行开发。其可以查阅的资源有：
