A React Native Folder Structure That Actually Scales

Most React Native codebases don't fail because of bad code. They fail because of bad organization — a giant components/ folder, a giant screens/ folder, and by feature #20 nothing lives anywhere near the thing it relates to. Here's the structure I use so a project stays navigable from day one to launch.

Organize by feature, not by file type

The default instinct is to group files by what they are: all components together, all hooks together, all screens together. That feels tidy early and becomes a scavenger hunt later.

Group by feature instead:

src/
  features/
    auth/
      screens/
      components/
      hooks/
      api.ts
    paywall/
    settings/
  components/   // genuinely shared, dumb UI
  lib/          // clients, config, helpers
  theme/        // design tokens
  navigation/

Everything a feature needs lives in one folder. When you delete a feature, you delete one directory — not twelve files scattered across the repo.

Keep shared UI actually shared

The top-level components/ folder should hold only dumb, reusable primitives — Button, Card, Input. The moment a component knows about auth or billing, it belongs inside that feature, not in shared.

A good test: if a component imports from a features/ folder, it shouldn't live in components/.

Small files, single responsibility

A screen file should orchestrate, not implement. If a screen is 400 lines, it's doing too much — pull the pieces into local components and hooks. This is the "S" in SOLID applied to UI: each file has one reason to change.

Use path aliases

Relative imports like ../../../lib/supabase are a smell. Configure an alias so imports read by intent:

{
  "compilerOptions": {
    "paths": { "@/*": ["./src/*"] }
  }
}

Now it's @/lib/supabase everywhere, and moving files doesn't break a chain of dots.

Why this matters for a solo dev

When you're the whole team, friction compounds. A structure where related code lives together means you spend your time building features instead of hunting for where things are. That's the difference between shipping in weeks and stalling for months.

This is the exact architecture my React Native Starter is built on — feature-based, typed, with a coding-standards doc — so a new project starts organized instead of drifting into chaos.

Takeaways

• Group by feature; colocate screens, components, and logic.
• Reserve the shared folder for truly generic UI.
• Keep files small with one responsibility.
• Use path aliases so imports read clearly and survive refactors.
