findRecord, findAll and peekRecord

findRecord fetches by id, findAll returns the full collection, and peekRecord pulls from the cache without making a request.

What you'll learn

Use the findRecord method with a type and id
Use findAll for full collections
Use peekRecord for cache-only sync reads

These three store methods cover most reads. Each has different semantics — pick based on whether you want fresh data, cached data, or one specific record.

findRecord

const post = await this.store.findRecord('post', 42);

First call: fetches GET /posts/42, caches the result, returns it.
Second call: returns the cached record immediately (still a Promise).
Force refresh:

await this.store.findRecord('post', 42, { reload: true });

findAll

const posts = await this.store.findAll('post');

First call: fetches GET /posts and caches all results.
Later calls: returns the cached collection.
Background refresh:

await this.store.findAll('post', { backgroundReload: true });

Returns the cache instantly, then quietly re-fetches and updates records as the response arrives.

peekRecord and peekAll

These never hit the network. They return whatever the store has cached, or null for a missing record.

const cached  = this.store.peekRecord('post', 42); // sync
const allInCache = this.store.peekAll('post');     // sync, live array

peekAll returns a live record array — it updates as records are added, removed, or unloaded.

When To Pick Which

Page load that needs fresh data: findRecord / findAll.
Side panel that just shows what’s already loaded: peekRecord / peekAll.
Snappy UX with eventual consistency: findAll(..., { backgroundReload: true }).
