Reconnector

Reflect the connection state in the UI (Blazor Server)

Usage

1. Add code in _Layout.cshtml

@RenderBody()

<div id="blazor-error-ui">
</div>

// add ReconnectorOutlet component
<component type="typeof(ReconnectorOutlet)" param-AutoReconnect="true" render-mode="ServerPrerendered" />

组件参数 AutoReconnect 用于控制是否开启网络重连，默认 true 已开启，可以通过 param-AutoReconnect="false" 关闭

2. Add code in App.razor

<Reconnector>
    <ReconnectingTemplate>
        <p>连接出现了一点小问题，需要重新连接。</p>
        <p>重新连接中，请稍后... 也可以立即 <a href="javascript:location.reload()">重新加载</a></p>
    </ReconnectingTemplate>
    <ReconnectFailedTemplate>
        <p>连接失败了，请确认网络是否正常。</p>
        <p>
            如果网络正常，你可以<a href="javascript:window.Blazor.reconnect()">重新连接</a>
            或者立即 <a href="javascript:location.reload()">重新加载</a>
        </p>
    </ReconnectFailedTemplate>
    <ReconnectRejectedTemplate>
        <p>所有的连接尝试都被拒绝了，这很有可能是由于网络问题或者服务器问题引起的。</p>
        <p>您可以尝试<a href="javascript:location.reload()">重新加载</a>服务器。如果是由于服务器问题引起的失败，重新连接可能不成功</p>
    </ReconnectRejectedTemplate>
</Reconnector>

Template

  • ReconnectingTemplate attempting to reconnect
  • ReconnectFailedTemplate reconnection failed
  • ReconnectRejectedTemplate reconnection rejected

The following table describes the CSS classes applied to the components-reconnect-modal element by the Blazor framework.

CSS class Indicates
components-reconnect-show A lost connection. The client is attempting to reconnect. Show the modal.
components-reconnect-hide An active connection is re-established to the server. Hide the modal.
components-reconnect-failed Reconnection failed, probably due to a network failure. To attempt reconnection, call window.Blazor.reconnect() in JavaScript.
components-reconnect-rejected
Reconnection rejected. The server was reached but refused the connection, and the user's state on the server is lost. To reload the app, call location.reload() in JavaScript. This connection state may result when:
  • A crash in the server-side circuit occurs.
  • The client is disconnected long enough for the server to drop the user's state. Instances of the user's components are disposed.
  • The server is restarted, or the app's worker process is recycled.

Application

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
