5. Initial Commit • 2021-12-15 5
6. Star History 6
7. Who is using Hono • cdnjs API Server • Drivly - Commerce infrastructure for the automotive industry • Ultra - Zero-Legacy Deno/React Suspense SSR Framework • Deno cli/bench/http 7
8. Workers Launchpad 8 ref: https://blog.cloud fl are.com/launchpad-fall-22/
9. Deno benchmarks 9 https://deno.land/benchmarks
10. Concept 1 Multi-runtimes 10
11. Hono works on... • Cloud fl are Workers / workerd • Vercel Edge Runtime • Fastly Compute@Edge • Deno • Bun • Node.js • and more... 11
12. The same code runs on all platforms 12
13. Cloudflare Workers and Bun
14. Fastly Compute@Edge and Vercel Edge Runtime
15. Deno
16. Node.js
17. Thanks to Web standards • Zero-dependencies / No poly fi ll • Web-interoperable Runtimes will be powered by WinterCG 17
18. Cloudflare Workers 18 ref: https://developers.cloud fl are.com/workers/runtime-apis/
19. Deno 19 ref: https://deno.land/manual@v1.28.2/runtime/web_platform_apis
20. Bun 20 ref: https://github.com/oven-sh/bun#Reference
21. Node.js 21 ref: https://github.com/honojs/node-server • Using `@remix-run/web-fetch`
22. context.ts 22 Discussion in WinterCG => https://github.com/wintercg/runtime-keys/pull/2
23. Great 👍 23
24. Concept 2 Ultrafast 24
25. Cloudflare Workers 25 ref: https://github.com/honojs/hono/tree/main/benchmarks/handle-event
26. Deno 26 ref: https://github.com/denosaurs/bench
27. Bun 27 ref: https://github.com/SaltyAom/bun-http-framework-benchmark
28. Node.js • Fastify • Reqs/sec 63417.00 5358.22 67487.06 • Express • Reqs/sec 20709.94 1683.03 23045.34 • Hono with @honojs/node-server • Reqs/sec 32054.95 2642.04 35583.36 28
29. Node.js - router 29 Decode URI, Handle Query strings Does not support regexp Does not support regexp
30. Why so fast? 30
31. 3+1 Routers 1. StaticRouter • Fastest, supports only static routes. 2. RegExpRouter • Faster, supports almost routes. 3. TrieRouter • Slowest, supports all routes. 
 But it's faster than other routers in the world. 31
32. "Linear" router 32
33. ref: https://github.com/yusukebe/pico
34. TrieRouter • Using Trie Tree structure • Support all patterns 34
36. RegExpRouter • Match the route with using one big Regex made before dispatch. • By @usualoma • https://speakerdeck.com/usualoma/ultrafast-js-router 36
37. 37
38. StaticRouter • Optimized for static routings • Does not support dynamic routings such as "path parameters" 38
40. SmartRouter • The default router • Automatically picks the best router from the three routers. 40 • StaticRouter • RegExpRouter • TrieRouter
41. Great 👍 41
42. Concept 3 Middleware 42
43. Small core • hono.ts • context.ts • compose.ts • request.ts 43 Basic app with Wrangler: Total Upload: 34.15 KiB / gzip: 8.26 KiB
44. Three types of Middleware • Built-in Middleware - including the package • Custom Middleware - created by the users • Third-party Middleware - depends on external libraries 44
45. Built-in Middleware • Basic Auth • Bearer Auth • Cache • Compress • CORS • Etag • html • JSX • JWT Auth • Logger • Pretty JSON • Serve Static • Validator 45
46. JSX Middleware 46
47. Validator Middleware 47
48. Custom Middleware 48
49. Third-party Middleware 49 • GraphQL Server • Firebase Auth • Sentry • tRPC (?) ref: https://github.com/honojs/hono/issues/582
50. Great 👍 50
51. Concept 4 Experience 51
52. TypeScript • Wrangler, Deno, and Bun fi rst-class support TypeScript. 52
53. Path parameters 53
54. Validator Middleware 54
55. Easy to write tests • With `jest-environment-mini fl are` • We can do test `Request` to `Response` 55
56. Great 👍 56
57. Example: Blog 57
58. import 58
59. Model 59
60. Logic 60
61. JSX 61
62. GET / 62
63. POST /post 63
64. Use cases in the real world 64
65. With Cloudflare R2 65 • github.com/yusukebe/r2-image-worker • Store and Deliver images with R2 backend Cloud fl are Workers. ref: https://github.com/yusukebe/r2-image-worker
66. With Cloudflare D1 66 ref: https://blog.cloud fl are.com/making-static-sites-dynamic-with-cloud fl are-d1/
67. Cache control 67 ref: https://yusukebe.com/posts/2022/wsh/
68. Express alternative on Bun 68
69. Feature plans 69
70. Ecosystem • For Third-party Middleware • monorepo • API specs as Types • tRPC like, but integrated 70
71. API specs as Types 71 ref: https://github.com/honojs/hono/issues/582
72. And... 72
73. Going to Standard web framework for Web standards 73
74. One more thing 74
75. Pico 75 Pico is ultra-tiny (about 1kB) web framework using URLPattern. Pico works on Cloud fl are Workers and Deno. Pico is compatible with Hono.
76. Love 76
