sse 4.1.0
sse: ^4.1.0 copied to clipboard

Provides client and server functionality for setting up bi-directional communication through Server Sent Events (SSE) and corresponding POST requests.

4.1.0 #

  • Limit the number of concurrent requests to prevent Chrome from automatically dropping them on the floor.

4.0.0 #

  • Support null safety.

3.8.3 #

  • Require the latest shelf and remove dead code.

3.8.2 #

  • Complete onConnected with an error if the SseClient receives an error before the connection is successfully opened.

3.8.1 #

  • Fix an issue where closing the SseConnection stream would result in an error.

3.8.0 #

  • Add onConnected to replace onOpen.
  • Fix an issue where failed requests would not add a done event to the connection sink.

3.7.0 #

  • Deprecate the client's onOpen getter. Messages will now be buffered until a connection is established.

3.6.1 #

  • Drop dependency on package:uuid.

3.6.0 #

  • Improve performance by buffering out of order messages in the server instead of the client.

** Note ** This is not modelled as a breaking change as the server can handle messages from older clients. However, clients should be using the latest server if they require order guarantees.

3.5.0 #

  • Add new shutdown methods on SseHandler and SseConnection to allow closing connections immediately, ignoring any keep-alive periods.

3.4.0 #

  • Remove onClose from SseConnection and ensure the corresponding sink.close correctly fires.

3.3.0 #

  • Add an onClose event to the SseConnection. This allows consumers to listen to this event in lue of sseConnection.sink.done as that is not guaranteed to fire.

3.2.2 #

  • Fix an issue where keepAlive may cause state errors when attempting to send messages on a closed stream.

3.2.1 #

  • Fix an issue where keepAlive would only allow a single reconnection.

3.2.0 #

  • Re-expose isInKeepAlivePeriod flag on SseConnection. This flag will be true when a connection has been dropped and is in the keep-alive period waiting for a client to reconnect.

3.1.2 #

  • Fix an issue where the SseClient would not send a done event when there was an error with the SSE connection.

3.1.1 #

  • Make isInKeepAlive on SseConnection private.

Note that this is a breaking change but in actuality no one should be depending on this API.

3.1.0 #

  • Add optional keepAlive parameter to the SseHandler. If keepAlive is supplied, the connection will remain active for this period after a disconnect and can be reconnected transparently. If there is no reconnect within that period, the connection will be closed normally.

3.0.0 #

  • Add retry logic.

Possible Breaking Change Error messages may now be delayed up to 5 seconds in the client.

2.1.2 #

  • Remove package:http dependency.

2.1.1 #

  • Use proper headers delimiter.

2.1.0 #

  • Support Firefox.

2.0.3 #

  • Fix an issue where messages could come out of order.

2.0.2 #

  • Support the latest package:stream_channel.
  • Require Dart SDK >=2.1.0 <3.0.0.

2.0.1 #

  • Update to package:uuid version 2.0.

2.0.0 #

  • No longer expose close and onClose on an SseConnection. This is simply handled by the underlying stream / sink.
  • Fix a bug where resources of the SseConnection were not properly closed.

1.0.0 #

  • Internal cleanup.

0.0.1 #

  • Initial commit.
