9. (My) Reality
10. (My) Reality • I want to create something. How exciting!
11. (My) Reality • I want to create something. How exciting! • I ask myself “Where do I put this code?”
12. (My) Reality • I want to create something. How exciting! • I ask myself “Where do I put this code?” • One macro module: Can’t reuse
13. (My) Reality • I want to create something. How exciting! • I ask myself “Where do I put this code?” • One macro module: Can’t reuse • Many micro modules: Hard to manage
14. (My) Reality • I want to create something. How exciting! • I ask myself “Where do I put this code?” • One macro module: Can’t reuse • Many micro modules: Hard to manage • OK, let’s just write many small modules!
15. What could go wrong?
17. The Human Condition
18. The Human Condition Action Location Operation
19. The Human Condition Action Location Operation Create editor, local fs Text → FS
20. The Human Condition Action Location Operation Create editor, local fs Text → FS Find deps editor, local fs DBnpm → FS
21. The Human Condition Action Location Operation Create editor, local fs Text → FS Find deps editor, local fs DBnpm → FS Commit .git/ FS → DBlg
22. The Human Condition Action Location Operation Create editor, local fs Text → FS Find deps editor, local fs DBnpm → FS Commit .git/ FS → DBlg Publish github DBlg → DBgh
23. The Human Condition Action Location Operation Create editor, local fs Text → FS Find deps editor, local fs DBnpm → FS Commit .git/ FS → DBlg Publish github DBlg → DBgh Package npm FS → DBnpm
24. The Human Condition Action Location Operation Create editor, local fs Text → FS Find deps editor, local fs DBnpm → FS Commit .git/ FS → DBlg Publish github DBlg → DBgh Package npm FS → DBnpm Test ci (apply [DBnpm, DBgh])
25. The Human Condition Action Location Operation Create editor, local fs Text → FS Find deps editor, local fs DBnpm → FS Commit .git/ FS → DBlg Publish github DBlg → DBgh Package npm FS → DBnpm Test ci (apply [DBnpm, DBgh]) Deploy ssh/chef [DB] →→ FSremote
26. COOL!
 
 Let’s do this for 100s of modules!
29. The Other World Theory
30. The Other World Theory Action Location Operation
31. The Other World Theory Action Location Operation Create browser Text → DB
32. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB
33. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB Commit browser DB → DB
34. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB Commit browser DB → DB Publish browser DBme → DByou | DBgh
35. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB Commit browser DB → DB Publish browser DBme → DByou | DBgh Package browser DBme → DBnpm
36. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB Commit browser DB → DB Publish browser DBme → DByou | DBgh Package browser DBme → DBnpm Test browser (apply DB)
37. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB Commit browser DB → DB Publish browser DBme → DByou | DBgh Package browser DBme → DBnpm Test browser (apply DB) Deploy browser (apply DBme)
38. The Other World Theory Action Location Operation Create browser Text → DB Find deps browser DB → DB Commit browser DB → DB Publish browser DBme → DByou | DBgh Package browser DBme → DBnpm Test browser (apply DB) Deploy browser (apply DBme) Deploy browser DBme → Container

41. The life of f
42. Action Code The life of f
43. Action Code Create onChange = sync f, test f, deploy f The life of f
44. Action Code Create onChange = sync f, test f, deploy f Sync (Commit, Publish & Package) db.get(f.id).set(‘source’, source) The life of f
45. Action Code Create onChange = sync f, test f, deploy f Sync (Commit, Publish & Package) db.get(f.id).set(‘source’, source) Test eval(bundle(f, test)) The life of f
46. Action Code Create onChange = sync f, test f, deploy f Sync (Commit, Publish & Package) db.get(f.id).set(‘source’, source) Test eval(bundle(f, test)) Deploy browser eval(bundle(f ))) The life of f
47. Action Code Create onChange = sync f, test f, deploy f Sync (Commit, Publish & Package) db.get(f.id).set(‘source’, source) Test eval(bundle(f, test)) Deploy browser eval(bundle(f ))) Deploy server postToDockerd(containerize(f )) The life of f
48. on change → everything happens, well-defined
49. findDeps
50. findDeps • Search undefined symbols in source
 undefs :: Source ! [UndefinedSymbol]
51. findDeps • Search undefined symbols in source
 undefs :: Source ! [UndefinedSymbol] • Resolve undefs into dependency tree
 resolveDeps :: FunDef ! FunDepTree
52. findDeps • Search undefined symbols in source
 undefs :: Source ! [UndefinedSymbol] • Resolve undefs into dependency tree
 resolveDeps :: FunDef ! FunDepTree • Locks current dependency version if unknown!
53. bundle
54. bundle • Concatenate dependency & entrypoint
 bundle :: FunDepTree ! Source
55. bundle • Concatenate dependency & entrypoint
 bundle :: FunDepTree ! Source • Run!
 evaluate(bundle(resolveDeps(f)))
56. db • DB is a CRDT document • Replicates peer to peer between all participants • Can be persisted to disk or browser storage
57. Browser as a compiler.
58. Browser as a compiler. • Replicates dependencies
59. Browser as a compiler. • Replicates dependencies • Checks code validity
60. Browser as a compiler. • Replicates dependencies • Checks code validity • Compiles code into JS bundle
61. Browser as a compiler. • Replicates dependencies • Checks code validity • Compiles code into JS bundle • Compilation result is cached in database
62. Browser as a compiler. • Replicates dependencies • Checks code validity • Compiles code into JS bundle • Compilation result is cached in database • Runs bundle in isolated context
64. (apply f )
