@microsoft/fetch-event-source - npm Package Versions

2.0.1

This release adds support for esmodule imports (see #4).

2.0.0

This release improves the performance of parsing the response stream and fixes some corner cases to better match the spec.

Changed

• The id, event, and data fields are now initialized to empty strings, per the spec (they were previously undefined)

• The onmessage callback is now called for all messages (it was previously triggered only for messages with a data field)

• If a message contains multiple data fields, they will be concatenated together into a single string. For example, the following message:

  data: Foo
  data:Bar
  data
  data: Baz
  

  will result in { data: 'Foo\nBar\n\nBaz' }

• If the server sends an id field with an empty value, the last-event-id header will no longer be sent on the next reconnect.

Removed

• The internal parseStream function has been removed. The parse implementation was previously based on async generators, which required a lot of supporting code in both the typescript-generated polyfill as well as the javascript engine. The new implementation is based on simple callbacks, which should be much faster.

1.0.2

Changed

• Updated examples in readme to fix typos, added more comments.
• Changed if statements in parse.ts to test for specific values instead of truthy/falsy values.

1.0.1

Changed

• Changed the default onOpen validator to allow charset and boundary directives in the content-type
