sse 4.1.2

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

4.1.2

• Send fetch requests instead of XHR requests.
• Add an optional debugKey parameter to SseClient to include in logging.
• Add a dependency on package:js.
• Update the minimum Dart SDK version to 2.16.0.

4.1.1

• Apply keepAlive logic to SocketExceptions.
• Switch from using package:pedantic to package:lints
• Rev the minimum required SDK to 2.15.
• Populate the pubspec repository field.

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.
