mobile-first shopping list and cart app, hosted entirely on [Val Town](https://val.town).\r\nReal Israeli grocery products and prices come from the free [Cheapersal API](https://cheapersal.co.il/developers)\r\n(built on the government price-transparency data).\r\n\r\n## Features\r\n\r\n- Search real grocery products in Hebrew (local catalog, instant, zero API quota).\r\n- Cart for the next shopping run with a live projected total (₪), based on the average price across chains.\r\n- Favorites for one-tap re-adding of staples.\r\n- Custom items with a user-set price for anything not in the catalog.\r\n- Shopping mode: scan barcodes (EAN-13/EAN-8) with the phone camera as items go into the physical cart,\r\n building the real expected total, then compare planned vs. scanned at checkout to catch register mistakes.\r\n- \"My store\" setting: scan lookups prefer your branch's actual price over the national average.\r\n- Installable PWA (Add to Home Screen on iPhone/Android), cart viewable offline in-store.\r\n\r\n## Project structure\r\n\r\n```\r\nbackend/\r\n index.http.ts Hono HTTP trigger: JSON API + serves the frontend, manifest, SW, icons\r\n db.ts SQLite schema + query helpers\r\n cheapersal.ts Cheapersal API client (throttle, daily budget, 24h price cache)\r\n icons.ts App icon (SVG -> PNG via resvg-wasm, cached in blob storage)\r\n syncCatalog.cron.ts Incremental catalog sync (cron trigger)\r\nfrontend/\r\n index.html, styles.css, manifest.json, sw.js\r\n index.js, app.js, views.js, scanner.js, api.js (React 18 + htm, no build step)\r\nshared/\r\n types.ts\r\n```\r\n\r\n## One-time setup\r\n\r\n1. Get a free API key at [cheapersal.co.il/developers](https://cheapersal.co.il/developers) (\"קבלו מפתח API\").\r\n2. Install [Deno](https://deno.land), then the Val Town CLI: `deno install -grAf jsr:@valtown/vt`, and run `vt` to log in.\r\n3. From this folder: `vt create sal-kniyot` (or `vt push` if the val exists).\r\n4. In the val's settings on val.town set environment variables:\r\n - `CHEAPERSAL_API_KEY` — your Cheapersal key.\r\n - `APP_PIN` — optional numeric PIN that gates the app (leave unset for no PIN).\r\n5. Set the cron schedule for `backend/syncCatalog.cron.ts` (e.g. every 30 minutes). The first runs build\r\n the local product catalog; afterwards it refreshes weekly.\r\n6. On the phone, open the val URL → Share → Add to Home Screen.\r\n\r\n## API quota strategy\r\n\r\nFree tier is 100 requests/day (10/minute). The app stays well inside it:\r\n\r\n- Product name search runs against the local SQLite catalog — zero quota.\r\n- Catalog sync uses a small request budget per cron run and stops at ~55 requests/day.\r\n- Live price lookups happen only when adding an item (cached 24h) or scanning an unknown barcode.\r\n- The settings sheet shows the remaining daily quota as reported by the API.\r\n",[148],"0d5f50ee-59c8-4c88-a552-84335087cdd1",".vtignore","93313bc0-6654-11f1-9529-1607ee4eb77e",9,["D",1781264955145],1,".git\r\n.git/**\r\n.vt\r\n.vt/**\r\n*.lock\r\nnode_modules/**\r\n",[155],"cd304fb9-8c75-4c5f-9592-65425d2ce241","shared","927c54f8-6654-11f1-aca0-1607ee4eb77e",3,["D",1781264884601],"directory",[163],"a76bc93f-97d0-4df8-9445-600c21b1eb32","frontend","92500ed4-6654-11f1-b967-1607ee4eb77e",2,["D",1781264884294],[170],"957b7828-2037-4489-87e5-b59a5c295272","backend","922a324a-6654-11f1-9e0e-1607ee4eb77e",["D",1781264884030],[176],"aa4c5e77-addb-4ead-adc7-cc2fbef21e6a",".vt","bb7ec82c-6654-11f1-98fc-1607ee4eb77e",8,["D",1781264953400],[181],"7b603636-18b2-423f-88d7-d7dee3c0d631",".git","929e2830-6654-11f1-92f4-1607ee4eb77e",4,["D",1781264884823],[187],"pulls","branches","forks","envVars",{"_199":172,"_201":60},"connections",{"_199":60,"_200":60},"count","unfilledCount","emptyCount",{"_42":186,"_31":187,"_29":188,"_139":-5,"_40":41,"_39":189,"_141":142,"_37":237,"_13":60,"_33":167,"_35":-5,"_23":24,"_145":-5,"_212":238,"_26":239},{"_42":180,"_31":181,"_29":182,"_139":-5,"_40":41,"_39":183,"_141":142,"_37":234,"_13":60,"_33":167,"_35":-5,"_23":24,"_145":-5,"_212":235,"_26":236},{"_42":175,"_31":176,"_29":177,"_139":-5,"_40":41,"_39":159,"_141":142,"_37":231,"_13":60,"_33":167,"_35":-5,"_23":24,"_145":-5,"_212":232,"_26":233},{"_42":227,"_31":32,"_29":30,"_139":177,"_40":41,"_39":14,"_141":142,"_37":228,"_13":60,"_33":34,"_35":36,"_23":24,"_145":-5,"_212":229,"_26":230},{"_42":169,"_31":170,"_29":171,"_139":-5,"_40":41,"_39":172,"_141":142,"_37":224,"_13":60,"_33":167,"_35":-5,"_23":24,"_145":-5,"_212":225,"_26":226},{"_42":162,"_31":163,"_29":164,"_139":-5,"_40":41,"_39":165,"_141":142,"_37":221,"_13":60,"_33":167,"_35":-5,"_23":24,"_145":-5,"_212":222,"_26":223},{"_42":154,"_31":155,"_29":156,"_139":-5,"_40":41,"_39":157,"_141":142,"_37":218,"_13":159,"_33":20,"_35":160,"_23":24,"_145":-5,"_212":219,"_26":220},{"_42":147,"_31":148,"_29":149,"_139":-5,"_40":41,"_39":150,"_141":142,"_37":215,"_13":60,"_33":20,"_35":152,"_23":24,"_145":-5,"_212":216,"_26":217},{"_42":136,"_31":137,"_29":138,"_139":-5,"_40":41,"_39":140,"_141":142,"_37":211,"_13":60,"_33":20,"_35":144,"_23":24,"_145":-5,"_212":213,"_26":214},["D",1781264886189],"children",[],[137],["D",1781264886602],[],[148],["D",1781264955145],[],[155],["D",1781264884601],[],[163],["D",1781264884294],[],[170],"d1aba5d3-b6c2-415e-9044-b637533de144",["D",1781265057129],[],[176,32],["D",1781264884030],[205],[176],["D",1781264953400],[],[181],["D",1781264884823],[],[187],["D",1781264881516],["D",1789535451117],{"_97":96,"_105":101},{"_97":96,"_98":99,"_100":101,"_18":54,"_102":103,"_104":24},{"_13":86,"_31":87,"_42":41,"_88":43,"_89":-5,"_90":-5,"_91":-5,"_92":-5,"_93":-5,"_94":44,"_95":96},"ctx",{"_79":-5,"_125":278,"_279":280,"_281":282,"_283":24,"_284":24,"_285":24,"_286":142,"_287":-5,"_288":-7,"_289":-7,"_290":60,"_291":24,"_292":24,"_293":-5,"_294":24,"_295":24,"_296":24,"_297":-5},"ENV",{"_249":250,"_251":252,"_253":87,"_254":255,"_256":257,"_258":259,"_260":261,"_262":263,"_264":265,"_266":267,"_268":269,"_270":271,"_272":273,"_274":275,"_276":277},"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"]
