react-dev

Overview of react-dev skill

The react-dev skill is a focused React + TypeScript reference and execution aid for teams building typed components, hooks, event handlers, router integrations, and newer React 19 patterns. If your real problem is “I know the React feature I want, but I want the type-safe version without trial and error,” this is the right fit.

What react-dev is best at

react-dev is strongest when you need patterns that are easy to get almost-right but costly to get subtly wrong:

• typed component props
• generic reusable components
• event and form handler typing
• useState, useRef, reducers, and custom hook typing
• React 19 changes such as ref as a prop, useActionState, and use()
• type-safe routing with React Router or TanStack Router

Who should install react-dev

This react-dev skill is most useful for:

• frontend developers working in React with TypeScript
• teams migrating from React 18 to React 19
• AI-assisted coding users who want fewer TypeScript fix loops
• developers building reusable UI primitives, forms, tables, lists, and route-aware components

Real job-to-be-done

Most users do not need “React advice” in general. They need working, typed React code that matches current patterns and compiles with less back-and-forth. react-dev for Frontend Development helps turn vague requests like “build a typed table” or “type this submit handler” into patterns that are already aligned with modern React usage.

Key differentiators vs a generic prompt

A normal prompt can produce plausible React code. react-dev is better when correctness depends on exact typing details and updated framework patterns. The repository includes concrete references for:

• generic components
• server component patterns
• event handlers
• hooks
• React 19 typing updates
• router-specific TypeScript setup

That makes it more useful than a broad prompt when you care about compile-time guarantees, not just JSX that looks reasonable.

When react-dev is not the right skill

Do not reach for react-dev if your project is:

• plain JavaScript React with no TypeScript goals
• non-React TypeScript
• mostly backend or API design work
• UI work where framework choice and typing strategy are still undecided

If you mainly need styling, design systems, or state architecture rather than typing patterns, this skill is helpful but not sufficient on its own.

How to Use react-dev skill

Install context for react-dev

If your agent setup supports skill installation from GitHub, install react-dev from the softaworks/agent-toolkit repository and then activate it for React TypeScript tasks. A common pattern is:

npx skills add softaworks/agent-toolkit --skill react-dev

If your environment exposes skills differently, use the equivalent add/import flow and confirm the skill points to skills/react-dev.

Read these files first

For a fast evaluation, do not start with the whole repository. Read in this order:

1. skills/react-dev/SKILL.md
2. skills/react-dev/README.md
3. skills/react-dev/references/react-19-patterns.md
4. skills/react-dev/references/hooks.md
5. skills/react-dev/references/event-handlers.md

Then open examples based on your task:

• examples/generic-components.md
• examples/server-components.md
• references/react-router.md
• references/tanstack-router.md

This path gets you to the high-value implementation details fastest.

What input react-dev needs from you

The react-dev usage quality depends heavily on concrete inputs. Provide:

• React version, especially if React 19 is involved
• framework context, such as Next.js, Vite, or plain React
• whether the code is client, server, or shared
• the exact UI element or hook you want
• relevant domain types
• router choice
• any compile errors or constraints

Weak input:

• “Build a typed form component”

Strong input:

• “Build a reusable React 19 form component in TypeScript for a Next.js app. It needs typed submit handling, field errors, and useActionState. Inputs are email and password. Return a production-ready component and explain key types.”

Turn a rough goal into a strong prompt

A good react-dev guide prompt usually includes five parts:

1. the component or hook to build
2. the data shape
3. the interaction pattern
4. the React/runtime context
5. the output format you want

Example:

• “Using the react-dev skill, create a generic Table<T> component with sortable columns, typed custom cell renderers, and a keyExtractor. Show props, usage with a User type, and explain where inference works.”

This is much better than:

• “Make a generic table in React TS”

Best workflow for actual tasks

A practical workflow for react-dev usage is:

1. state the exact React feature involved
2. tell the agent your version and runtime context
3. ask for the minimal typed implementation first
4. then ask for ergonomics, edge cases, and refactors
5. finally run TypeScript and feed back any errors verbatim

That workflow is especially effective for hooks, refs, event handlers, and router setup where small type mismatches matter.

Use react-dev for React 19 migration work

One of the most decision-relevant reasons to install react-dev is React 19 coverage. The repository specifically calls out newer patterns such as:

• ref as a prop instead of defaulting to forwardRef
• useActionState
• use()
• server component patterns

If your team is updating older code, ask explicitly for “React 19-safe” or “migration-oriented” output so the agent does not fall back to older idioms by habit.

Where react-dev helps most with typing pain

The highest-value areas are not random. They are the places where teams usually lose time:

• empty array and nullable state typing
• DOM refs vs mutable refs
• event target/currentTarget confusion
• generic prop design
• route parameter and loader typing
• server/client boundary mistakes

Using react-dev for these is more valuable than using it for simple presentational components.

Strong prompt patterns by task type

For components:

• specify props, variants, children behavior, and ref needs

For hooks:

• specify inputs, return shape, async behavior, and error/loading states

For event handlers:

• specify the element type and desired event behavior

For routers:

• specify router library, route mode, and whether generated types are already configured

For server components:

• specify what must stay on the server and what must become a client component

Practical repository-backed examples to borrow

The repo is most actionable when you mirror its example structure:

• use examples/generic-components.md for tables, lists, selects, and reusable form fields
• use examples/server-components.md for async server components, data fetching, and server actions
• use references/event-handlers.md when an event type is the blocker
• use references/hooks.md when hook inference or ref behavior is the blocker

This is more efficient than asking the model to improvise from scratch.

Constraints and tradeoffs to know before adoption

react-dev install makes more sense if your team values correctness over novelty. The skill is reference-heavy and pattern-oriented. That is a strength for compile-safe output, but less ideal if you want speculative architecture, state management strategy, or framework-agnostic UI advice.

It also assumes you are solving React TypeScript problems, not just writing JSX quickly.

react-dev skill FAQ

Is react-dev better than a normal React prompt?

For typed React work, usually yes. A generic prompt may produce code that looks fine but uses weaker types, outdated patterns, or vague event typing. react-dev improves reliability by grounding the output in specific React TypeScript patterns and repository references.

Is react-dev good for beginners?

Yes, if you are already learning React with TypeScript and want examples that compile. It is less useful for absolute beginners who still need first-principles explanations of React itself. The skill assumes you know what components, hooks, and routing are.

Does react-dev only help with React 19?

No. The react-dev skill covers React 18 to 19 patterns, but React 19 is one of its clearest differentiators because many examples online still lean on older assumptions.

When should I not use react-dev?

Skip react-dev when:

• your project is JavaScript-only
• you need framework selection advice
• your main blocker is CSS or design system work
• you are not solving a TypeScript-related React problem

Can react-dev help with router typing?

Yes. The repository includes references for both React Router and TanStack Router, which is useful if your issue is route params, generated types, loader context, or route-aware component typing.

Does react-dev cover server components?

Yes. The skill includes server component examples and React 19 patterns, so it is a reasonable fit when your task involves async server components, server actions, or use()-related patterns.

How to Improve react-dev skill

Give react-dev exact runtime and library versions

The fastest way to improve react-dev results is to provide version context up front:

• React 18 or 19
• TypeScript version if relevant
• Next.js / Vite / Remix / custom setup
• React Router or TanStack Router version or mode

This prevents the model from mixing patterns across generations of docs.

Include your real types, not placeholders

The quality jump is large when you provide your own data types. Compare:

Weak:

• “Type a modal component”

Better:

• “Type a generic modal component for User | Admin editing, with onClose, onSubmit, and controlled form fields. Use a discriminated union for the payload.”

Real types let react-dev produce better prop contracts and fewer hand-wavy generics.

Ask for the type decisions, not just the code

If you want more durable output, ask the agent to explain:

• why a generic parameter is needed
• where inference should happen
• when to use explicit unions
• why an event type matches a specific element
• whether a ref should be nullable or mutable

This turns react-dev usage from copy-paste output into reusable team knowledge.

Common failure modes to watch for

Even with react-dev, review output for these issues:

• overuse of any
• using older forwardRef patterns when React 19 context was requested
• overly broad event types like React.SyntheticEvent when a specific event is needed
• hooks returning tuples or objects without stable, clear typing
• generic components that do not preserve inference at the call site

These are the places where you should ask for a revision, not patch manually in silence.

Improve first-pass output with a stricter request format

A high-performing prompt template for react-dev is:

• goal
• framework/runtime
• domain types
• constraints
• desired output
• validation requirement

Example:

• “Use react-dev to write a reusable Select<T> for React 19. Context: Vite + TypeScript. Types: User { id: string; name: string }. Needs controlled value, typed onChange, optional ref, and accessible label support. Output component, example usage, and note any React 19-specific choices.”

Iterate using compiler feedback

The best improvement loop is simple:

1. generate with react-dev
2. run tsc or your app build
3. paste the exact error back
4. ask for a minimal fix, not a rewrite

Exact compiler messages help the skill converge faster than broad statements like “it doesn't work.”

Extend react-dev with task-specific references

If your team uses repeated patterns, pair the react-dev guide with your own internal examples:

• house style for form components
• approved route type helpers
• common domain entities
• preferred error/loading state conventions

The skill becomes much more effective when grounded in your app’s actual types and conventions rather than generic sample models.

Focus react-dev on high-value moments

To get the most from react-dev for Frontend Development, use it where typing precision changes correctness:

• reusable components
• migrations
• server/client boundaries
• hooks shared across features
• route-aware code
• event-heavy forms and inputs

For trivial leaf components, a plain prompt is often enough. For anything reusable or migration-sensitive, react-dev earns its keep.
