You are an expert in TypeScript, Node.js, Remix, React, Shadcn UI and Tailwind.
Code Style and Structure:
- Write concise, technical TypeScript code with accurate examples
- Use functional and declarative programming patterns; avoid classes
- Prefer iteration and modularization over code duplication
- Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError)
- Structure files: exported component, subcomponents, helpers, static content, types
Naming Conventions:
- Use lowercase with dashes for directories (e.g., components/auth-wizard)
- Favor named exports for components
TypeScript Usage:
- Use TypeScript for all code; prefer types over interfaces
- Use functional components with TypeScript interfaces
Syntax and Formatting:
- Create functions using `const fn = () => {}`
- Avoid unnecessary curly braces in conditionals; use concise syntax for simple statements
- Use declarative JSX
- Never use 'use client'
- Never use 1 line if statements
Error Handling and Validation:
- Prioritize error handling: handle errors and edge cases early
- Use early returns and guard clauses
- Implement proper error logging and user-friendly messages
- Use Zod for form validation
- Model expected errors as return values in Server Actions
- Use error boundaries for unexpected errors
UI and Styling:
- Use Shadcn UI, Radix, and Tailwind Aria for components and styling
- Implement responsive design with Tailwind CSS; use a mobile-first approach
- When using Lucide icons, prefer the longhand names, for example HomeIcon instead of Home
React forms
- Use zod for form validation react-hook-form for forms
- Look at TeamCreateDialog.tsx as an example of form usage
- Use <Form> <FormItem> elements, and also wrap the contents of form in a fieldset which should have the :disabled attribute when the form is loading
TRPC Specifics
- Every route should be in it's own file, example routers/teams/create-team.ts
- Every route should have a types file associated with it, example routers/teams/create-team.types.ts. These files should have the OpenAPI meta, and request/response zod schemas
- The request/response schemas should be named like Z[RouteName]RequestSchema and Z[RouteName]ResponseSchema
- Use create-team.ts and create-team.types.ts as an example when creating new routes.
- When creating the OpenAPI meta, only use GET and POST requests, do not use any other REST methods
- Deconstruct the input argument on it's one line of code.
Toast usage
- Use the t`string` macro from @lingui/react/macro to display toast messages
Remix/ReactRouter Usage
- Use (params: Route.Params) to get the params from the route
- Use (loaderData: Route.LoaderData) to get the loader data from the route
- When using loaderdata, deconstruct the data you need from the loader data inside the function body
- Do not use json() to return data, directly return the data
Translations
- Use <Trans>string</Trans> to display translations in jsx code, this should be imported from @lingui/react/macro
- Use the t`string` macro from @lingui/react/macro to display translations in typescript code
- t should be imported as const { t } = useLingui() where useLingui is imported from @lingui/react/macro
- String in constants should be using the t`string` macro
