4## Typescript

7- Use `pnpm` or `pnpx` and not `npm` or `npx`.
8  - Use `just js_shadcn`, `just pnpm`, and `just js_lint` instead of executing these operations exactly. @just/javascript.just
9- Node libraries are not available
10- Use `lib/` for generic code, `utils/` for project utilities, `hooks/` for React hooks, and `helpers/` for page-specific helpers.
11- Prefer `function theName() {` over `const theName = () =>`
12- Use `import { invariant } from @epic-web/invariant` instead of another invariant library
13- Use `requireEnv("VITE_THE_ENV_VAR")` instead of `process.env.THE_ENV_VAR`
14- Don't use `console.{log,error}`. Use `from ~/configuration/logging import log` and `log.info("string", {structured: "log"})` instead.

16Here's how frontend code is organized in `web/app/`:
17 
18- `lib/` not specific to the project. This code could be a separate package at some point.
19- `utils/` project-specific code, but not specific to a particular page.
20- `helpers/` page- or section-specific code that is not a component, hook, etc.
21- `hooks/` react hooks.
22- `configuration/` providers, library configuration, and other setup code.
23- `components/` react components.
24  - `ui/` reusable ShadCN UI components (buttons, forms, etc.).
25  - `shared/` components shared across multiple pages.
26  - create additional folders for route- or section-specific components.

28### Dates & Times
29 
30* Always use the ISO 8601 format when sending dates in an API request.
31* Use `Temporal` for any date or time manipulation. You can assume it's available in the browser.
32* DateTime objects should always be converted to UTC before included in any API request. Never send a timestamp with the user's timezone.
33* Unless otherwise specified, do not shift server-provided times based on the user's timezone.
