28. Concurrency in the browser
29. JavaScript and the golden thread
33. foo() 10ms 20ms 30ms 40ms click handled click fired setInterval (10ms)
35. Synchronous —vs— Asynchronous
36. WebWorkers
37. JavaScript Thread Worker
38. Worker JavaScript Thread
39. Worker Worker JavaScript Thread
40. Dedicated, Shared & Inline Workers
42. orange
43. The queue
44. Define a worker
45. # workers/sum.coffee importScripts 'orange/worker.js' perform (data)-> data.numbers.reduce (a, b)-> a + b
46. # workers/sum.coffee importScripts 'orange/worker.js' perform (data)-> data.numbers.reduce (a, b)-> a + b
47. Create a new job
48. job = new Orange.Job('sum', numbers: [1..100])
49. job = new Orange.Job('sum', numbers: [1..100]) job.on 'success', (response) -> console.log('Sum', response) job.perform()
50. Events
51. job.on 'success', (response)-> job.on 'complete', -> job.on 'error', (error)-> job.on 'failure', (error)->
52. Logging
53. # workers/sum.coffee importScripts 'orange/worker.js' perform (data)-> log 'The background worker Gotham deserves ...' data.numbers.reduce (a, b) ->a + b
54. Batches
55. batch = new Orange.Batch
56. batch = new Orange.Batch job = new Orange.Job('sum', [1..100]) batch.push job batch.perform()
57. batch = new Orange.Batch [job1, job2, job3]
58. batch.on 'complete', (jobs) -> batch.on 'job:success', (job) -> batch.on 'job:complete', (job)-> batch.on 'job:error', (job) -> batch.on 'job:failure', (job) ->
59. job.getResponse() job.getLastError()
60. Configuration
61. Orange.Config.set maxWorkerPoolSize: 4 maxRetries : 3 workersPath : '/lib/workers/'
62. Retry mechanism and exponential back–off
63. Error handling
64. job.on 'error', (error)-> throw error BatchStateTransitionError JobStateTransitionError ResponderNotFoundError …
66. Roadmap >0.2.0
67. Customized Worker Shim Test coverage Data serialization Benchmarking
68. Forward arbitrary method calls to worker? Custom events? Instrumentation? Inline Workers? Helper modules?
69. Kiitos!
