feat(database): setup backend with drizzle orm and configure eslint#1
Conversation
- Initialize Drizzle ORM configuration and database schema in the backend. - Configure ESLint with simple-import-sort and other plugins for both backend and frontend. - Refactor frontend components to comply with new linting rules.
WalkthroughThis PR establishes backend database infrastructure using Drizzle ORM with a PostgreSQL schema, adds ESLint configurations with import/export sorting rules to both backend and frontend codebases, and applies import/attribute reordering to frontend code to align with new linting rules.

Import ordering violates the newly configured simple-import-sort rules.
dotenv/config, drizzle-orm/node-postgres, and pg all belong to the same group (^@?\\w). The blank line between pg and dotenv/config breaks that group, and the alphabetical order within the group is wrong. npm run lint will fail on this file.

Unhandled pg.Pool error event can crash the process.
When an idle client in the pool encounters a network-level error, pg emits an 'error' event on the pool itself. Without a listener, Node.js treats this as an unhandled exception and will terminate the process.

updatedAt columns will never auto-update — add .$onUpdate().
.defaultNow() only sets the value at INSERT time. When using $onUpdate() or $onUpdateFn(), Drizzle adds a dynamic update value to the column; the function is called when the row is updated, and the returned value is used as the column value if none is provided. Without it, both users.updatedAt and orders.updatedAt will permanently equal their original createdAt value unless the application manually sets them.
This applies identically to orders.updatedAt at Lines 360–362.

checkoutSessions is absent from both usersRelations and has no relation object of its own.
usersRelations only declares orders: many(orders), leaving out checkoutSessions. Additionally, there is no checkoutSessionsRelations export declaring the user: one(users, …) side. Any Drizzle query using with: { checkoutSessions: true } on a user, or with: { user: true } on a checkout session, will throw a runtime error.

eslint v10 removed context.getFilename breaking changes
Yes. ESLint v10.0.0 removed the deprecated rule context APIs including context.getFilename. In custom rules (and any ecosystem plugins still using the old API), you must use context.filename instead. What changed (ESLint v10): - context.getFilename → context.filename - context.getCwd → context.cwd - context.getPhysicalFilename → context.physicalFilename - context.getSourceCode → context.sourceCode - context.parserOptions → context.languageOptions or context.languageOptions.parserOptions - context.parserPath → no replacement This removal is part of the official ESLint v10 migration guidance and release notes. For example, the “Migrate to v10.x” doc states that in ESLint v10.0.0 “all of these members have been removed” and provides the replacement mapping for context.getFilename.

eslint-plugin-react 7.37.5 incompatible eslint 10
eslint-plugin-react@7.37.5 is incompatible with ESLint 10 (both for installation/peer-dependency constraints and at runtime in some cases). Evidence: 1) Installation/peer dependency conflicts: users reported npm resolution failures when pairing eslint-plugin-react@7.37.5 with eslint@10.x (peer range not including v10). 2) Runtime incompatibility: reports show crashes like “contextOrFilename.getFilename is not a function” when ESLint 10 tries to run rules such as react/no-render-return-value. 3) The plugin’s published peer dependency range on npm includes eslint up to the 9.x line (peerDependencies show ^3 || … || ^9.7, not ^10). What to do: - If you need ESLint 10 now: pin eslint to a supported version (e.g., ESLint 9.x) until eslint-plugin-react officially supports ESLint 10. - If/when a future eslint-plugin-react release adds ESLint 10 support (updates peerDependencies / fixes for ESLint 10 rule-context API changes), upgrade to that version. Note: A related React lint plugin (eslint-plugin-react-hooks) had ESLint 10 peer-dependency support work merged into the project and later released versions with ESLint 10 support; this does not automatically mean eslint-plugin-react (the main plugin) is compatible at v7.37.5.

"contextOrFilename.getFilename is not a function" eslint-plugin-react
The error "contextOrFilename.getFilename is not a function" occurs when using eslint-plugin-react with ESLint v10. ESLint v10 removed the legacy context.getFilename API that eslint-plugin-react relies on for React version auto-detection in rules like react/display-name. This is a known compatibility issue, primarily affecting Next.js projects via eslint-config-next which depends on eslint-plugin-react ~7.37.x. Workarounds: 1. Downgrade ESLint to v9.x: "eslint": "^9.0.0" 2. Explicitly set React version in eslint config to bypass auto-detection: settings: { react: { version: "detect" } // or "18.x", "19.x" etc. } For flat config (eslint.config.js): { settings: { react: { version: "detect" } } } 3. Use @eslint/compat to polyfill legacy APIs if using flat config. 4. Switch to modern alternatives like @eslint-react/eslint-plugin (native ESLint 10 support). eslint-plugin-react-hooks has ESLint v10 support since v7+. Long-term: Update eslint-plugin-react when v8+ releases with full ESLint v10 compatibility (PRs in progress).

eslint-plugin-react@7.37.5 is incompatible with eslint@10.2.1 — linting will crash at runtime
ESLint v10.0.0 removed deprecated rule context methods including context.getFilename(). When using eslint-plugin-react@7.37.5 with ESLint 10, it throws TypeError: Error while loading rule 'react/display-name': contextOrFilename.getFilename is not a function because the plugin's internal version.js utility (used by every react/* rule) still calls this removed API. The plugin's peer dependencies explicitly exclude ESLint 10 support (capped at ^9.7), causing runtime failures for any React rules that trigger version detection.
Both npm run lint and npm run lint:fix will fail before any rule is applied.
Options:
- Downgrade ESLint to
^9.x—eslint-plugin-react@7.37.5is compatible with ESLint v9. - Wait for
eslint-plugin-react@8+— work is in progress upstream to add ESLint v10 support.
Interim workaround (if staying on ESLint v10): add settings: { react: { version: "detect" } } to the jsx-sort-props config block in eslint.config.js. This bypasses the dynamic version auto-detection code path that calls the removed API.
