| description | Framework (OSS). Expo's official example projects - the expo/examples repo of ~70 `with-*` integrations (Stripe, Clerk, Supabase, OpenAI, maps, Reanimated, SQLite, Skia, NativeWind, and more). Use when integrating a third-party library or service into an existing Expo app and you want the canonical, version-matched pattern to adapt, or when scaffolding a new project from one with `npx create-expo --example`. |

Expo Examples
expo/examples is Expo's official library of ~70 integration examples — directories named with-<library> (e.g. with-stripe, with-maps), each built around one library or service. These are not full apps: they're managed projects (no ios//android/ dirs — native setup is via config plugins), and the typical one is a single screen of ~100–200 lines. Mine them for the canonical integration pattern — the dependency set, app.json config plugins, and minimal wiring Expo maintains against the current SDK — and adapt that into the user's app. Don't expect to lift an application architecture from them.
Reach for an example before hand-rolling an integration. (Kinds — full-stack, showcases, starters — are noted in ./references/catalog.md.)
Two modes
- Inspiration / adapt (most common) — the user already has a project. Find the matching example, read its key files, and apply the pattern to their code.
- Scaffold — greenfield. Start a fresh project directly from the example.
Workflow
1. Find the right example
Map the user's need to an example name (e.g. payments → with-stripe, auth → with-clerk). ./references/catalog.md is a categorized snapshot for fast triage — but it drifts, so confirm against the live list:
gh api repos/expo/examples/contents --jq '.[] | select(.type=="dir" and (.name|startswith(".")|not)) | .name'
gh api repos/expo/examples/contents/meta.json --jq '.content' | base64 -d
meta.json is the source of truth for what's renamed or dead (deprecated examples are removed from the repo tree but still listed here, each with a message). If an example is in its deprecated map, don't recommend it — follow the message to the modern path. If it's in aliases, use the destination.
2a. Inspiration mode — study without touching the user's project
The common case: the user already has an app and wants to see how Expo does something. Read the example as reference and apply the patterns by hand — never scaffold an example on top of their project.
First, list the whole example in one call. Integration code is often nested (e.g. Stripe's server routes live in app/api/), so a one-level listing misses the important files:
gh api 'repos/expo/examples/git/trees/master?recursive=1' \
--jq '.tree[].path | select(startswith("with-stripe/"))'
Then read the high-signal files first: README.md (setup) → package.json (deps) → app.json (config plugins / permissions) → the integration code the manifest revealed → .env (required secrets). Per file:
gh api repos/expo/examples/contents/with-stripe/utils/stripe-server.ts --jq '.content' | base64 -d
curl -s https://raw.githubusercontent.com/expo/examples/master/with-stripe/utils/stripe-server.ts
Reading more than a couple of files? Many integrations are spread across server routes, a client provider, and config (Stripe is). Skip the per-file calls — pull the whole example into a throwaway/gitignored dir (not the user's project) and read it freely with Grep/Read, then apply by hand:
npx degit expo/examples/with-stripe /tmp/expo-ref/with-stripe
git clone --depth 1 --filter=blob:none --sparse https://github.com/expo/examples.git /tmp/expo-ref/examples \
&& (cd /tmp/expo-ref/examples && git sparse-checkout set with-stripe)
Read from there with Grep/Read; delete the scratch dir when done.
2b. Scaffold mode — new project from an example
npx create-expo --example with-stripe
bun create expo --example with-stripe
3. Adapt into the user's app — non-destructively (critical)
When the user already has an app, add only what the example introduces; never overwrite their setup.
- Version-align — don't copy pinned versions. Examples track the latest SDK, so their
package.json pins won't match an older project. Add only the missing deps with npx expo install <pkg> (it resolves SDK-correct versions) instead of copying exact versions.
- Merge config, don't replace it. Add only the
app.json/app.config.* plugins and permissions the example introduces that the user lacks — keep their existing config block intact.
- Port the integration code.
- Recreate env vars from the example's
.env shape — it holds placeholders, never working secrets.
Done when the integration code is ported and every dependency, config plugin, permission, and env var it needs is accounted for in the user's app — not when it merely looks wired up.
Gotchas
- Default branch is
master, not main (matters for raw URLs and sparse checkout).
- Single-click deploy. Every example has a launch URL:
https://launch.expo.dev/?github=https://github.com/expo/examples/tree/master/<example>.
