List or Fetch

This query handles both single-record lookups (when a uri param is provided) and paginated listing.

Lexicon type: query

function handle()
  if params.uri then
    local record = db.get(params.uri)
    if not record then
      return { error = "record not found" }
    end
    return { record = record }
  end

  return db.query({
    collection = collection,
    did = params.did,
    limit = tonumber(params.limit) or 20,
    cursor = params.cursor,
  })
end

How it works

1. If a uri query parameter is provided, fetch that single record with db.get and return it. If it doesn’t exist, return a structured error (using error() would trigger a 500 response).
2. Otherwise, list records from the target collection using db.query, with optional filtering by did and cursor-based pagination. The cursor is an opaque string from a previous response — pass it through directly. Since limit arrives as a string, tonumber() converts it to a number.

Usage

GET /xrpc/xyz.statusphere.listRecords?limit=10
GET /xrpc/xyz.statusphere.listRecords?did=did:plc:abc
GET /xrpc/xyz.statusphere.listRecords?uri=at://did:plc:abc/xyz.statusphere.record/abc123

Use case

Useful when one endpoint needs to handle both listing and single-record fetches.
