- SqlStore interface + CF D1 wrapper + per-module factory (table prefix convention)
- init signature extended to ({ db, sql, env }); sql is null when DB binding absent
- custom migration runner walks src/modules/*/migrations/*.sql, tracks applied in _migrations table
- npm run db:migrate with --dry-run and --local flags; chained into deploy
- fake-d1 test helper with subset of SQL semantics for retention and history tests
Portfolio schema now uses meta object: { currency, assets, meta: { invested } }.
Migrates old totalvnd field automatically on load. The meta object provides
a clean place for future per-user metadata without polluting the top level.
Replace hardcoded 9-symbol registry with dynamic TCBS-based resolution.
Any VN stock ticker is now resolved on first use and cached in KV
permanently. Portfolio flattened from 4 category maps to single assets
map with automatic migration of old format. Crypto, gold, and currency
exchange disabled with "coming soon" message.
Replace hardcoded 0.5% spread with live buy/sell rates from BIDV bank
API. Buying USD uses bank's sell rate (higher), selling USD uses bank's
buy rate (lower). Reply shows both rates and actual spread percentage.
Topup now only accepts VND — users must convert to get other currencies.
Convert uses a 0.5% bid/ask spread: buying USD costs more VND (ask),
selling USD back gives less VND (bid). Simulates real forex behavior.
Paper trading system with 5 commands (trade_topup, trade_buy,
trade_sell, trade_convert, trade_stats). Supports VN stocks via TCBS,
crypto via CoinGecko, forex via ER-API, and gold via PAX Gold proxy.
Per-user portfolio stored in KV with 60s price caching. 54 new tests.
grammY-based bot with a module plugin system loaded from the MODULES env
var. Three command visibility levels (public/protected/private) share a
unified command namespace with conflict detection at registry build.
- 4 initial modules (util, wordle, loldle, misc); util fully implemented,
others are stubs proving the plugin system end-to-end
- util: /info (chat/thread/sender ids) + /help (pure renderer over the
registry, HTML parse mode, escapes user-influenced strings)
- KVStore interface with CFKVStore and a per-module prefixing factory;
getJSON/putJSON convenience helpers; other backends drop in via one file
- Webhook at POST /webhook with secret-token validation via grammY's
webhookCallback; no admin HTTP surface
- Post-deploy register script (npm run deploy = wrangler deploy && node
--env-file=.env.deploy scripts/register.js) for setWebhook and
setMyCommands; --dry-run flag for preview
- 56 vitest unit tests across 7 suites covering registry, db wrapper,
dispatcher, help renderer, validators, and HTML escaper
- biome for lint + format; phased implementation plan under plans/
