- Registering as a Share Target: share_target in Manifest: Include a share_target section in your PWA's manifest file (e.g., manifest.json). Example:
{
"name": "My PWA",
"scope": "/",
"share_target": {
"action": "/share/",
"method": "GET",
"enctype": "application/x-www-form-urlencoded",
"params": {
"title": "name",
"text": "description",
"url": "link"
}
}
}```
action: Specifies the URL path where shared data will be sent.
method: Determines whether the data is sent via GET or POST.
enctype: Specifies the encoding type, often application/x-www-form-urlencoded.
params: Defines the parameters that will be passed in the request (e.g., title, text, url).
2. Receiving Shared Data:
GET Request: If method is "GET", the shared data will be passed as query parameters in the URL.
POST Request: If method is "POST", the shared data will be sent as the request body.
JavaScript: Use JavaScript to access the shared data, depending on the method and enctype.
Example (GET):
```JavaScript
const params = new URLSearchParams(window.location.search);
const title = params.get('title');
const text = params.get('text');
const url = params.get('url');
- Important Considerations: Installability:
Your PWA must meet Chrome's installability criteria to be registered as a share target.
User Action: The user needs to add your PWA to their home screen before they can share content to it.
Scope: Ensure your scope in the manifest is correctly set to the root of your PWA, or the action path will be ignored.
Browser Compatibility: Check the browser compatibility table for the Web Share Target API.
File Sharing: The Web Share Target API supports sharing files, but it requires a few tweaks to the manifest.
