Improv Wi-Fi Serial SDK for the browser
npm install improv-wifi-serial-sdkIf you are using a bundler and JavaScript package manager, you can install the SDK via NPM:
``
npm install --save improv-wifi-sdk
And then import it in your code:
`
import 'improv-wifi-serial-sdk';
Add the following to your website to show a button to start the provisioning process:
`html`
A warning message will be rendered if the browser does not support WebSerial.
The SDK will render an error when the connected device does not support Improv. If it is opt-in for your software, you can set a link as the learnMoreUrl attribute to include this link in the error message.
`html`
>
The following attributes are automatically added to and can be used for styling:
| Attribute | Description |
| -- | -- |
| supported | Added if this browser is supportedunsupported
| | Added if this browser is not supported
It is possible to customize the button and the message. You do this by putting your elements inside the element and adding the appropriate slot attribute. Use activate to replace the activation button and unsupported to replace the unsupported message:
`html`
Your browser does not support provisioning.
When the dialog is closed, a closed event will be fired on both and . This event will have a detail property with the following properties:
- improv: Boolean indicating if we connected to a device running Improv.provisioned
- : Boolean indicating if the device is connected to Wi-Fi.
This SDK requires a browser with support for WebSerial. Currently this is supported by Google Chrome, Microsoft Edge and other browsers based on the Blink engine.
No iOS devices are supported.
The serial SDK can also be used standalone without the UI.
