Fetching the blob:\n\n - The client-side React component makes a fetch request to \"/image\".\n - This request is handled by our server function.\n\n\n2. Server-side handling:\n\n - The server function calls `blob.get(\"test.png\")`.\n - This `blob.get()` method makes an HTTP request to the Val Town API.\n - The API returns a Response object containing the image data.\n\n\n3. Processing the blob on the server:\n\n - We receive this Response object from `blob.get()`.\n - We don't need to extract the data on the server side.\n - We can directly return this Response object to the client.\n\n\n4. Sending the response to the client:\n\n - We set the appropriate \"Content-Type\" header (e.g., \"image/png\").\n - We return the Response object to the client.\n\n\n5. Client-side handling:\n\n - The fetch request in the React component receives the Response.\n - We call `response.blob()` to get a Blob object from the Response.\n\n\n6. Creating a data URL:\n\n - We create a FileReader object.\n - We use FileReader to read the Blob as a data URL.\n - This data URL is a base64-encoded string representing the image.\n\n\n7. Updating the React state:\n\n - We set the data URL as the state of our component.\n\n\n8. Rendering the image:\n\n - We use the data URL as the src attribute of an `` tag.\n - The browser decodes the base64 data and renders the image.\n\n## Further reading on Val Town blobs\n\n- [Blob storage overview in Val Town docs](https://docs.val.town/std/blob/)\n- [Val Town REST API references for blobs](https://docs.val.town/openapi#tag/blobs)\n- [Val Town blob std lib source code](https://www.val.town/v/std/blob)",[58],{"_34":57,"_13":58,"_37":59,"_39":-5,"_40":41,"_42":60,"_44":45,"_46":71,"_17":62,"_49":24,"_51":63,"_53":54,"_55":-5,"_68":72,"_18":73},{"_34":35,"_13":36,"_37":38,"_39":-5,"_40":41,"_42":43,"_44":45,"_46":67,"_17":48,"_49":50,"_51":52,"_53":54,"_55":-5,"_68":69,"_18":70},["D",1727801615583],"children",[],[36],["D",1727709954507],[],[58],"30e6c764-2785-11f0-b46e-569c3dd06744",["D",1746211345302],"deletedAt","legacyEnvVars","privacy","public","httpPrivacy","description","imageUrl","userId","97567c3b-8285-4589-880d-547c23383b76","pinnedFileId","pinPreview","pinMigrated","screenshotVersion","likeCount","orgId","112e17ac-118d-4072-aca6-a4ddc6b3970f","tursoName","tursoHostname","tursoMeasuredAt","pinned","userPerm","r","valPerm","blobPerm","rw","emailPerm","sqlitePerm","projectPerm","telemetryPerm","user",{"_11":12,"_126":122},"org",{"_11":12,"_120":-5,"_121":122,"_83":84,"_123":124,"_125":54},"branch",{"_17":43,"_13":16,"_34":41,"_112":74,"_113":-5,"_114":-5,"_115":-5,"_116":-5,"_117":-5,"_118":14,"_119":12},"isOwned","projectId","forkedBranchId","forkedBranchVersion","forkedProjectPrivacy","forkedProjectId","forkedProjectOrgId","projectName","userHandle","displayName","avatar","https://img.clerk.com/eyJ0eXBlIjoicHJveHkiLCJzcmMiOiJodHRwczovL2ltYWdlcy5jbGVyay5kZXYvb2F1dGhfZ2l0aHViL2ltZ18yaG5kR0hRRTM0S1BSeXlIR2hCdjFqb1dTS3AifQ","tier","pro","canRestrictVals","profileImageUrl","adoptOrgId",{"_34":74,"_13":14,"_46":164,"_76":-5,"_77":45,"_78":79,"_80":79,"_81":-5,"_82":-5,"_83":84,"_85":38,"_86":45,"_87":-5,"_88":-5,"_89":62,"_90":91,"_92":-5,"_93":-5,"_94":-5,"_95":-5,"_96":97,"_98":97,"_99":100,"_101":100,"_102":100,"_103":97,"_104":97,"_105":165,"_107":166,"_109":167,"_111":54},[158,159],"files",[158,159],"counts",{"_149":62,"_150":60,"_151":60,"_31":152,"_153":154},[145,146],"upstreamProject","upstreamBranch","emptyEnvVars","flags",[],"hasHttpFiles","grants","orgs","customDomains",{},{"_34":57,"_13":58,"_37":59,"_39":-5,"_40":41,"_42":60,"_44":45,"_46":61,"_17":62,"_49":24,"_51":63,"_53":54,"_55":-5,"_18":148},{"_34":35,"_13":36,"_37":38,"_39":-5,"_40":41,"_42":43,"_44":45,"_46":47,"_17":48,"_49":50,"_51":52,"_53":54,"_55":-5,"_18":147},[36],[58],"pulls","branches","forks",{"_155":62,"_157":62},"connections",{"_155":62,"_156":62},"count","unfilledCount","emptyCount",{"_34":57,"_13":58,"_37":59,"_39":-5,"_40":41,"_42":60,"_44":45,"_46":71,"_17":62,"_49":24,"_51":63,"_53":54,"_55":-5,"_68":162,"_18":163},{"_34":35,"_13":36,"_37":38,"_39":-5,"_40":41,"_42":43,"_44":45,"_46":67,"_17":48,"_49":50,"_51":52,"_53":54,"_55":-5,"_68":160,"_18":161},[],[36],[],[58],["D",1746211345302],{"_11":12,"_126":122},{"_11":12,"_120":-5,"_121":122,"_83":84,"_123":124,"_125":54},{"_17":43,"_13":16,"_34":41,"_112":74,"_113":-5,"_114":-5,"_115":-5,"_116":-5,"_117":-5,"_118":14,"_119":12},"ctx",{"_105":-5,"_142":201,"_202":203,"_204":205,"_206":54,"_207":54,"_208":54,"_209":45,"_210":-5,"_211":-7,"_212":-7,"_213":62,"_214":54,"_215":54,"_216":-5,"_217":54,"_218":54,"_219":54,"_220":-5},"ENV",{"_172":173,"_174":175,"_176":16,"_177":178,"_179":180,"_181":182,"_183":184,"_185":186,"_187":188,"_189":190,"_191":192,"_193":194,"_195":196,"_197":198,"_199":200},"REACT_APP_SENTRY_DSN","https://586020d86f05489db63a554690acf1e9@o1398359.ingest.sentry.io/6724499","RENDER_GIT_COMMIT","e87eb04e707cf64e7e532c8e8ec395f209e17f15","RENDER_GIT_BRANCH","POSTHOG_API_TOKEN","phc_nmoyuAkStEZuUp69rYlg1DZgrIt19Gx0Y4Hwf8tGgJP","POSTHOG_API_HOST","https://wart.val.town","WEB_API_TEMPLATE","https://{val}.web.val.run","APP_URL","https://www.val.town","MODULE_URL","https://esm.town","VANITY_WEB_API_TEMPLATE","https://{label}.val.run/","DENOLS_URL","https://lsp.val.town","NODE_ENV","production","CLOUDFLARE_TURNSTILE_SITE_KEY","0x4AAAAAACtaIZJH7s9rBMZ6","GOOGLE_CLIENT_ID","875989696899-jtsqkhlbdv5jrlsk8631p7ipjg3c6o62.apps.googleusercontent.com","STRIPE_PUBLISHABLE_KEY","pk_live_51N2zvWEpZTTLipIkVEwXrUG9AT0yeOOEYxszarZT1jpsZV58Ly6wlg3SltZpHN26CUalOBmUSY7adQRQiSkCZz2500qSXNkf8Y","API_URL","https://api.val.town",[],"preferencesKeybindings","default","preferencesTheme","light","preferencesFixers","preferencesCopilot","preferencesSelectionAi","preferencesCloseBrackets","preferencesChatPanelState","preferencesDprint","preferencesDenofmt","notificationCount","flagDenols","isBusinessOrgMember","businessOrgHandle","isBusinessOrgAdmin","isHigherTownieTier","navCollapsed","currentOrgId"]
