Defaults are\nconservative: dry-run, no overwrite, and copy (not move).\n\n## Files\n\n| File | Purpose |\n| ------------ | ------------------------------------------------------------------ |\n| `migrate.ts` | The importable library — `migrateBlobs(keys, options)`. |\n| `keys.ts` | `getKeysToMigrate()` — define *which* blobs to migrate here. |\n| `run.ts` | Runnable entrypoint that wires the two together (dry-run default). |\n\n## Quick start\n\n1. Edit `keys.ts` to return the keys you want to migrate (explicit list,\n prefix match, or filter — examples are in the file).\n2. Run `run.ts`. It performs a **dry run** by default and prints a report.\n3. When the report looks right, set `COMMIT = true` in `run.ts` and run again.\n\n## Library usage\n\n```ts\nimport { migrateBlobs } from \"https://esm.town/v/nbbaier/migrate-blob/migrate.ts\";\n\nconst summary = await migrateBlobs([\"my-config\", \"images/logo.png\"], {\n commit: true, // default false (dry run)\n});\n\nconsole.log(summary.counts);\n// { migrated, \"skipped-exists\", \"skipped-missing\", \"dry-run\", error }\n```\n\n### `migrateBlobs(keys, options)`\n\n| Option | Default | Behavior |\n| -------------- | ------- | ------------------------------------------------------------------------ |\n| `commit` | `false` | When `false`, nothing is written — only reports what *would* happen. |\n| `overwrite` | `false` | When `false`, keys already in scoped storage are skipped (idempotent). |\n| `deleteSource` | `false` | When `true`, deletes from global after a successful copy (i.e. a *move*). Ignored unless `commit`. |\n| `onProgress` | — | Callback `(result) => void` invoked after each key. |\n\nReturns a `MigrateSummary`: `{ results, counts, dryRun }`, where each result is\n`{ key, status, sourceDeleted?, error? }`.\n\n### Statuses\n\n- `migrated` — copied from global to scoped.\n- `skipped-exists` — already present in scoped storage (re-run safe).\n- `skipped-missing` — not found in global storage.\n- `dry-run` — would have migrated, but `commit` was `false`.\n- `error` — see the `error` field.\n\n## How it works\n\n```mermaid\nflowchart LR\n A[\"getKeysToMigrate()\"] --> B[\"migrateBlobs(keys)\"]\n B --> C{\"exists in scoped?\"}\n C -- yes, no overwrite --> S[\"skipped-exists\"]\n C -- no --> D{\"exists in global?\"}\n D -- no --> M[\"skipped-missing\"]\n D -- yes --> E{\"commit?\"}\n E -- no --> R[\"dry-run\"]\n E -- yes --> F[\"stream global → scoped\"]\n F --> G{\"deleteSource?\"}\n G -- yes --> H[\"delete from global\"]\n G -- no --> I[\"migrated (copy)\"]\n H --> I\n```\n\n## Notes\n\n- Global and scoped blobs are stored separately; you can't reach one through\n the other's interface — hence this migration.\n- Keys can be up to 512 chars. Total storage counts toward your plan limit\n (1 GB on Pro); during a copy (not move) the data exists in *both* stores.\n",[157],"pulls","branches",1,"forks","envVars",{"_171":67,"_173":67},"connections",{"_171":67,"_172":67},"count","unfilledCount","emptyCount",{"_48":156,"_38":157,"_36":158,"_140":-5,"_46":47,"_45":159,"_142":54,"_43":184,"_13":144,"_39":26,"_41":161,"_30":54,"_146":-5,"_178":185,"_33":186},{"_48":148,"_38":149,"_36":150,"_140":-5,"_46":47,"_45":151,"_142":54,"_43":181,"_13":153,"_39":40,"_41":154,"_30":54,"_146":-5,"_178":182,"_33":183},{"_48":137,"_38":138,"_36":139,"_140":-5,"_46":47,"_45":141,"_142":54,"_43":177,"_13":144,"_39":40,"_41":145,"_30":54,"_146":-5,"_178":179,"_33":180},["D",1781279360255],"children",[],[138],["D",1781279392443],[],[149],["D",1781278510681],[],[157],["D",1781278028334],["D",1789494036282],{"_104":103,"_111":107},{"_104":103,"_105":-5,"_106":107,"_19":61,"_108":109,"_110":54},{"_13":93,"_38":94,"_48":47,"_95":49,"_96":-5,"_97":-5,"_98":-5,"_99":-5,"_100":-5,"_101":50,"_102":103},"ctx",{"_86":-5,"_131":225,"_226":227,"_228":229,"_230":54,"_231":54,"_232":54,"_233":31,"_234":-5,"_235":-7,"_236":-7,"_237":67,"_238":54,"_239":54,"_240":-5,"_241":54,"_242":54,"_243":54,"_244":-5},"ENV",{"_196":197,"_198":199,"_200":94,"_201":202,"_203":204,"_205":206,"_207":208,"_209":210,"_211":212,"_213":214,"_215":216,"_217":218,"_219":220,"_221":222,"_223":224},"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"]
