From abc114b24e448a33d2a4f583cdc7ae191940bdca Mon Sep 17 00:00:00 2001 From: Lance Ball Date: Fri, 22 May 2020 13:03:36 -0400 Subject: [PATCH] lib!: change CloudEvent to use direct object notation and get/set properties (#172) This commit makes a substantial change to the API, changing the CloudEvent class to accept properties as an object in the constructor. For example: ```js const CloudEvent = require('cloudevents-sdk'); // all event properties except extensions may be set in the constructor const event = new CloudEvent({ source: 'http://my.event.source', type: 'test-event-type' }); // get and set all properties standard property notation console.log(event.time); // the event timestamp event.subject = 'my event subject'; ``` Signed-off-by: Lance Ball --- .jsdoc.json | 3 +- README.md | 8 +- docs/BinaryHTTPEmitter.html | 2 +- docs/BinaryHTTPReceiver.html | 11 +- docs/CloudEvent.html | 3081 +++++++---------- docs/HTTPEmitter.html | 9 +- docs/HTTPReceiver.html | 5 +- docs/StructuredHTTPEmitter.html | 17 +- docs/StructuredHTTPReceiver.html | 11 +- docs/ValidationError.html | 2 +- docs/bindings_http_emitter_binary.js.html | 18 +- docs/bindings_http_emitter_structured.js.html | 2 +- docs/bindings_http_http_emitter.js.html | 14 +- docs/bindings_http_http_receiver.js.html | 2 +- docs/bindings_http_receiver_binary.js.html | 4 +- .../bindings_http_receiver_structured.js.html | 4 +- ...ndings_http_v03_emitter_binary_0_3.js.html | 78 +- .../bindings_http_v1_emitter_binary_1.js.html | 71 +- ...s_http_validation_validation_error.js.html | 4 +- docs/cloudevent.js.html | 452 ++- docs/formats_json_parser.js.html | 11 +- docs/global.html | 18 +- docs/index.html | 10 +- lib/bindings/http/emitter_binary.js | 2 +- lib/bindings/http/http_emitter.js | 2 +- lib/bindings/http/v03/emitter_binary_0_3.js | 18 +- lib/bindings/http/v03/receiver_binary_0_3.js | 2 +- lib/bindings/http/v03/spec_0_3.js | 288 +- lib/bindings/http/v1/emitter_binary_1.js | 18 +- lib/bindings/http/v1/receiver_binary_1.js | 2 +- lib/bindings/http/v1/receiver_structured_1.js | 10 +- lib/bindings/http/v1/spec_1.js | 257 +- lib/bindings/http/validation/binary.js | 43 +- lib/bindings/http/validation/structured.js | 36 +- .../http/validation/validation_error.js | 2 +- lib/cloudevent.js | 450 ++- lib/formats/json/parser.js | 9 +- plugins/ignore-typedef.js | 6 + test/bindings/http/http_emitter_test.js | 75 +- .../http/promiscuous_receiver_test.js | 20 +- .../http/receiver_binary_0_3_tests.js | 38 +- test/bindings/http/receiver_binary_1_tests.js | 29 +- .../http/receiver_structured_0_3_test.js | 114 +- .../http/receiver_structured_1_test.js | 101 +- test/cloud_event_test.js | 175 + test/http_binding_0_3.js | 73 +- test/http_binding_1.js | 350 +- test/sdk_test.js | 14 +- test/spec_0_3_tests.js | 93 +- test/spec_1_tests.js | 82 +- 50 files changed, 2933 insertions(+), 3213 deletions(-) create mode 100644 plugins/ignore-typedef.js create mode 100644 test/cloud_event_test.js diff --git a/.jsdoc.json b/.jsdoc.json index 241c13a..cb69f6f 100644 --- a/.jsdoc.json +++ b/.jsdoc.json @@ -9,7 +9,8 @@ "excludePattern": "(node_modules/|docs|examples|coverage|test)" }, "plugins": [ - "plugins/markdown" + "plugins/markdown", + "plugins/ignore-typedef" ], "templates": { "referenceTitle": "cloudevents-sdk", diff --git a/README.md b/README.md index 9cd673b..2ef13e1 100644 --- a/README.md +++ b/README.md @@ -78,11 +78,9 @@ const { CloudEvent, HTTPEmitter } = require("cloudevents-sdk"); const v1Emitter = new HTTPEmitter({ url: "https://cloudevents.io/example" }); -const event = new CloudEvent() - .type(type) - .source(source) - .time(new Date()) - .data(data) +const event = new CloudEvent({ + type, source, data +}); // By default, the emitter will send binary events v1Emitter.send(event).then((response) => { diff --git a/docs/BinaryHTTPEmitter.html b/docs/BinaryHTTPEmitter.html index c37b40a..1a30adb 100644 --- a/docs/BinaryHTTPEmitter.html +++ b/docs/BinaryHTTPEmitter.html @@ -73,7 +73,7 @@ -
