In order to meet the demands of developers for launching on various platforms and truly achieve development in one place and running everywhere, 1.4 version began to support multi-platform export. Projects created by developers through the editor can be quickly exported to the projects required by different platforms.
|
||
|
||
## Prepare in Advance
|
||
After the project is developed in the editor, you can export the project for each platform and publish it. Before exporting, let's first understand the export panel and export settings.
|
||
|
||
### Export Panel
|
||
When we complete the project development and need to export it to a certain platform (taking exporting to the WechatMiniGame platform as an example), we can follow the steps below:
|
||
|
||
1、Click the Export button on the left side of the editor:
|
||
|
||

|
||
|
||
2、On the left side of the export panel that appears, select the export platform:
|
||
|
||
<Image src="https://mdn.alipayobjects.com/huamei_w6ifet/afts/img/A*50WSQoBlxpcAAAAAAAAAAAAADjCHAQ/fmt.webp" />
|
||
|
||
3、On the right side of the export panel are some project-related export configurations, which are mainly divided into two parts: **General configuration** (in the red box) and **Platform-related configuration** (in the yellow box):

|
||
|
||
### Export Configuration Instructions
|
||
|
||
The platform-related export configuration will be described separately in the platform export document. Here we focus on the **general configuration** that is independent of the platform.
|
||
|
||
| Configuration | Describe |
|
||
| ------------- | --------------------------------------------------------------------------------------------------------------------------------- |
|
||
| Project Name | Project name. The root directory name exported to the local computer is the project name. |
