fix(mcpb): reduce bundle size from 84MB to ~45MB (#184)
* fix(mcpb): reduce bundle size from 84MB to ~25MB (#183) - Move prisma to devDependencies (not needed at runtime) - Use --omit=peer in npm install to prevent prisma CLI peer dep bloat - Strip non-SQLite Prisma WASM runtimes (sqlserver, cockroachdb, postgresql, mysql) - Remove source maps, .d.ts, fixtures, test dirs from node_modules - Remove build artifacts (tsconfig.tsbuildinfo, dist/*.js.map) - Skip prisma generate in bundle (already compiled in dist/) - Add bundle size CI check (max 30 MB) - Update pino 10.3.0, undici 7.19.1, @cloudflare/workers-types * fix(mcpb): keep PostgreSQL WASM runtime, remove CI size check - Project uses PostgreSQL (not SQLite) — keep postgresql WASM, strip sqlserver/cockroachdb/sqlite/mysql instead - Remove bundle size CI step (unnecessary overhead) * fix(mcpb): remove WASM stripping, move form-data and typed-doc to devDeps - Remove Prisma WASM runtime stripping entirely (keep all runtimes) - Remove form-data from deps (unused, Node.js has native FormData) - Move @graphql-typed-document-node/core to devDeps (type-only imports) - Keep @clack/prompts and open in deps (needed for npm CLI usage)
