Honcho TypeScript SDK Migration (v1.6.0 → v2.1.1)
Overview
This skill migrates code from @honcho-ai/sdk v1.6.0 to v2.1.1 (required for Honcho 3.0.0+).
Key breaking changes:
@honcho-ai/coredependency removed- "Observation" → "Conclusion" terminology
- "Deriver" → "Queue" terminology
getConfig/setConfig→getConfiguration/setConfigurationsnake_case→camelCasethroughout- Streaming via
chatStream()instead ofchat({ stream: true }) Representationclass removed (returns string now)
Quick Migration
1. Update dependencies
Remove @honcho-ai/core from package.json. The SDK now has its own HTTP client.
2. Replace .core with .http
// Before
const workspace = await client.core.workspaces.getOrCreate({ id: 'my-workspace' })
// After
const response = await client.http.post('/v3/workspaces', { body: { id: 'my-workspace' } })
3. Rename configuration methods
// Before
await honcho.getConfig()
await honcho.setConfig({ key: 'value' })
await peer.getConfig()
await session.getConfig()
// After
await honcho.getConfiguration()
await honcho.setConfiguration({ reasoning: { enabled: true } })
await peer.getConfiguration()
await session.getConfiguration()
4. Rename listing methods
// Before
const peers = await honcho.getPeers()
const sessions = await honcho.getSessions()
const workspaces = await honcho.getWorkspaces() // string[]
// After
const peers = await honcho.peers()
const sessions = await honcho.sessions()
const workspaces = await honcho.workspaces() // Page<string>
5. Update streaming
// Before
const stream = await peer.chat('Hello', { stream: true })
// After
const stream = await peer.chatStream('Hello')
6. Update observations → conclusions
// Before
peer.observations
peer.observationsOf('bob')
maxObservations: 50
includeMostDerived: true
// After
peer.conclusions
peer.conclusionsOf('bob')
maxConclusions: 50
includeMostFrequent: true
7. Update queue status methods
// Before
await honcho.getDeriverStatus({ observer: peer })
await honcho.pollDeriverStatus({ timeoutMs: 60000 }) // REMOVE - see note below
// After
await honcho.queueStatus({ observer: peer })
// pollDeriverStatus() has no replacement - see note below
Important: pollDeriverStatus() and its polling pattern have been removed entirely. Do not rely on the queue ever being empty. The queue is a continuous processing system—new messages may arrive at any time, and waiting for "completion" is not a valid pattern. If your code previously polled for queue completion, redesign it to work without that assumption.
8. Convert snake_case to camelCase
// Before
message.peer_id
message.session_id
message.created_at
message.token_count
{ observe_me: true, observe_others: false }
{ created_at: '2024-01-01' }
// After
message.peerId
message.sessionId
message.createdAt
message.tokenCount
{ observeMe: true, observeOthers: false }
{ createdAt: '2024-01-01' }
9. Update representation calls
// Before
const rep = await peer.workingRep(session, target, options)
console.log(rep.explicit) // ExplicitObservation[]
console.log(rep.deductive) // DeductiveObservation[]
// After
const rep = await peer.representation({ session, target, ...options })
console.log(rep) // string
10. Move updateMessage to session
// Before
await honcho.updateMessage(message, metadata, session)
// After
await session.updateMessage(message, metadata)
11. Update card() to getCard() (v2.0.1+)
// Before
const card = await peer.card(target)
// After (v2.0.1+)
const card = await peer.getCard(target) // Returns string[] | null
// peer.card() still works but is deprecated — use getCard()
// New: setPeerCard / setCard
await peer.setCard(['Prefers dark mode', 'Located in US'])
12. Strict input validation (v2.0.2+)
Client constructor and all input schemas now reject unknown options via .strict() Zod validation.
// Before (v2.0.1 and earlier) — silently ignored
const honcho = new Honcho({ baseUrl: 'http://...' }) // typo: baseUrl vs baseURL — silently fell back to default
// After (v2.0.2+) — throws ZodError
const honcho = new Honcho({ baseUrl: 'http://...' }) // ZodError! Use baseURL
13. peer() and session() always make API calls (v2.1.0+)
Breaking: peer() and session() now always make a get-or-create API call. Previously, calling without metadata/configuration returned a lazy object with no API call.
// Before (v2.0.x) — no API call without options
const session = honcho.session('my-session') // Lazy, no network request
// After (v2.1.0+) — always hits the API
const session = await honcho.session('my-session') // Makes POST to /sessions (get-or-create)
14. New properties and methods (v2.1.0+)
// createdAt on Peer and Session
const peer = await honcho.peer('user-123')
console.log(peer.createdAt) // string | undefined
const session = await honcho.session('sess-1')
console.log(session.createdAt) // string | undefined
// isActive on Session
console.log(session.isActive) // boolean | undefined
// getMessage() on Session
const msg = await session.getMessage('msg-id')
15. Pagination parameters on list methods (v2.1.0+)
All list methods now accept page, size, and reverse parameters:
// Before (v2.0.x) — only filters
const peers = await honcho.peers({ metadata: { role: 'admin' } })
// After (v2.1.0+) — pagination controls via options object
const peers = await honcho.peers({
filters: { metadata: { role: 'admin' } },
page: 2,
size: 25,
reverse: true
})
// Legacy raw-filter form still works:
const peers = await honcho.peers({ metadata: { role: 'admin' } })
// Works on: honcho.peers(), honcho.sessions(), honcho.workspaces(),
// peer.sessions(), session.messages(), scope.list()
16. searchQuery moved in context() (v2.1.0+)
Breaking: searchQuery removed from top-level context() options. Use representationOptions.searchQuery instead.
// Before (v2.0.x)
await session.context({ searchQuery: '...' })
// After (v2.1.0+)
await session.context({ representationOptions: { searchQuery: '...' } })
17. Broader fetch retry logic (v2.1.1+)
The SDK now retries on all TypeError network failures (connection resets, DNS errors, etc.) instead of only those with 'fetch' in the message. No code changes needed — this is transparent.
