Every read and write is\ntransparently namespaced by the branch of the val that calls it, so `main` and\nyour feature branches never see each other's data — with no change to the public\nAPI.\n\n## Why\n\nWhen you fork a branch to experiment, you usually don't want it reading from or\nclobbering the blobs your `main` branch depends on. `blob-branch` solves this by\nprefixing every key with the current branch name behind the scenes.\n\n## Usage\n\n```ts\nimport { blob } from \"https://esm.town/v/nbbaier/blob-branch/main.ts\";\n\nawait blob.setJSON(\"config\", { theme: \"dark\" });\nconst config = await blob.getJSON(\"config\"); // { theme: \"dark\" }\n\nawait blob.list(); // keys are returned un-namespaced\nawait blob.delete(\"config\");\n```\n\nThe API mirrors `std/blob`: `get`, `set`, `getJSON`, `setJSON`, `list`,\n`delete`, `copy`, and `move`.\n\n## How it works\n\n```mermaid\nflowchart LR\n A[\"blob.set('config', …)\"] --> B[\"branchKey('config')\"]\n B --> C[\"getBranchName()\"]\n C --> D[\"parseVal()
(VALTOWN_ENTRYPOINT)\"]\n D --> E[\"branch = 'main'\"]\n E --> F[\"__branch/main/config\"]\n F --> G[\"/v2/blob API\"]\n```\n\n- `getBranchName(val?)` parses a val URL and returns its branch. With no\n argument it defaults to `VALTOWN_ENTRYPOINT` — the val currently executing —\n so it reports the branch of **whatever val calls a blob function**.\n- Keys are stored under `__branch//`.\n- `list()` filters by the branch prefix and strips the namespace off returned\n keys, so callers always see their original key names.\n- `copy`, `move`, `getJSON`, and `setJSON` build on the core functions, so they\n inherit branch-awareness automatically.\n\n### Example: same key, different data per branch\n\n| Branch | Call | Raw stored key |\n| ------- | --------------------------- | ----------------------------- |\n| `main` | `blob.set(\"config\", …)` | `__branch/main/config` |\n| `dev` | `blob.set(\"config\", …)` | `__branch/dev/config` |\n\nThe two writes never collide.\n\n## API\n\n| Function | Description |\n| ------------------------- | ----------------------------------------------------- |\n| `getBranchName(val?)` | Branch of the given val URL, or the current val. |\n| `blob.get(key)` | Get a blob as a `Response`. |\n| `blob.set(key, value)` | Store a blob (`BodyInit`). |\n| `blob.getJSON(key)` | Get and parse JSON, or `undefined` if not found. |\n| `blob.setJSON(key, val)` | Store a value as JSON. |\n| `blob.list(prefix?)` | List blob metadata for the current branch. |\n| `blob.delete(key)` | Delete a blob. |\n| `blob.copy(prev, next)` | Copy a blob to a new key. |\n| `blob.move(prev, next)` | Copy then delete the original. |\n\n## Caveats\n\n- **Existing data isn't migrated.** Blobs written before adopting this client\n live at their old un-prefixed keys and won't be visible through the branched\n API. Migrate them under `__branch//` if you need them.\n- The reserved prefix is `__branch/`. Avoid storing your own keys there.\n",[170],"pulls","branches","forks","envVars",{"_183":68,"_185":68},"connections",{"_183":68,"_184":68},"count","unfilledCount","emptyCount",{"_50":169,"_39":170,"_37":171,"_142":-5,"_48":49,"_47":172,"_144":33,"_45":204,"_13":68,"_40":26,"_42":174,"_30":33,"_148":-5,"_192":205,"_34":206},{"_50":162,"_39":163,"_37":164,"_142":-5,"_48":49,"_47":165,"_144":33,"_45":201,"_13":68,"_40":41,"_42":167,"_30":33,"_148":-5,"_192":202,"_34":203},{"_50":154,"_39":155,"_37":156,"_142":-5,"_48":49,"_47":157,"_144":33,"_45":198,"_13":159,"_40":41,"_42":160,"_30":33,"_148":-5,"_192":199,"_34":200},{"_50":150,"_39":35,"_37":38,"_142":-5,"_48":49,"_47":14,"_144":33,"_45":195,"_13":152,"_40":41,"_42":44,"_30":33,"_148":-5,"_192":196,"_34":197},{"_50":139,"_39":140,"_37":141,"_142":-5,"_48":49,"_47":143,"_144":33,"_45":191,"_13":146,"_40":41,"_42":147,"_30":33,"_148":-5,"_192":193,"_34":194},["D",1781286258871],"children",[],[140],["D",1781286316740],[],[35],["D",1781286302404],[],[155],["D",1781286269419],[],[163],["D",1781286010434],[],[170],["D",1781281066791],["D",1789497655664],{"_105":104,"_112":108},{"_105":104,"_106":-5,"_107":108,"_19":62,"_109":110,"_111":33},{"_13":94,"_39":95,"_50":49,"_96":51,"_97":-5,"_98":-5,"_99":-5,"_100":-5,"_101":-5,"_102":52,"_103":104},"ctx",{"_87":-5,"_131":245,"_246":247,"_248":249,"_250":33,"_251":33,"_252":33,"_253":31,"_254":-5,"_255":-7,"_256":-7,"_257":68,"_258":33,"_259":33,"_260":-5,"_261":33,"_262":33,"_263":33,"_264":-5},"ENV",{"_216":217,"_218":219,"_220":95,"_221":222,"_223":224,"_225":226,"_227":228,"_229":230,"_231":232,"_233":234,"_235":236,"_237":238,"_239":240,"_241":242,"_243":244},"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"]
