Changelog
v0.3.4All notable changes to @syncagent/js and @syncagent/react.
v0.3.4
latestMay 14, 2026Bug fixes, new features across all SDKs, and Vue/Angular version alignment
FixbaseUrl config was ignored — always used hardcoded URL. Now correctly respects user-provided baseUrl for development/self-hosted setups.
FixReact Provider useMemo only tracked apiKey/connectionString — now detects changes to filter, operations, language, and all other config options.
FixVue composable mutated placeholder message object directly — now uses separate streaming variable for clean reactivity.
FixReact hook stale isLoading closure could allow double-sends — now uses ref to check current value.
Newcontext field added to ChatOptions type — TypeScript users now get autocomplete for context in chat options.
NewonMessage callback in ChatOptions — fires for each complete message, useful for logging/analytics.
NewgetSchema() now retries once on network errors — matches the retry behavior of chat().
NewConnection string validation — warns on unrecognized format at construction time (doesn't throw, just console.warn).
NewsetMessages exposed from React useSyncAgent and Vue useSyncAgent — lets users hydrate conversation history from their own backend.
NewAngular: isConfigured signal — templates can disable inputs until configure() is called.
NewAngular: onError and onStatus callbacks in SyncAgentServiceConfig — log errors to Sentry/etc without subscribing to observables.
NewVue: onStatus callback in useSyncAgent options — react to status changes without watching the ref.
NewdetectPageContext() now exported from all framework packages (@syncagent/react, @syncagent/vue, @syncagent/angular, @syncagent/nextjs).
ImprovedDeduplicated request body construction in JS SDK — extracted buildRequestBody() helper to prevent drift between retry paths.
ImprovedVue and Angular packages bumped from 0.1.0 to 0.3.4 — all packages now share the same version number.
ImprovedAll package.json files now include homepage and repository fields for better npm discoverability.
ImprovedREADME files updated across all packages with Get Your API Key section, pricing table, supported databases, and links to docs.
v0.3.3
April 15, 2026System instructions, write confirmation, language, maxResults, sensitive fields, middleware hooks & bug fixes
NewsystemInstruction config — customize the agent's personality, tone, domain rules. Prepended to system prompt with priority.
NewconfirmWrites config — agent describes write operations and waits for explicit user confirmation before executing
Newlanguage config — agent responds entirely in the specified language (French, Spanish, Japanese, etc.). Field names stay in English.
NewmaxResults config — configurable default query limit (default 50). Set lower for mobile, higher for dashboards.
NewsensitiveFields config — specify which fields the agent masks. Default: password, token, secret.
NewonBeforeToolCall / onAfterToolCall middleware hooks — intercept client tool calls for logging, audit, or dynamic blocking
NewVanilla JS widget now supports filter, context, systemInstruction, language, and confirmWrites
Fixdatabase_overview now always counts live from DB instead of using stale cached schema counts
FixReact hook streaming no longer mutates state objects directly — uses ref-based accumulator
NewAutomatic retry on network errors — 1 retry with 1s delay on fetch failures (not on HTTP errors or aborts)
v0.3.2
April 8, 2026Auto page detection, structured context, and multi-tenant filter fixes
NewAuto page detection — SDK automatically detects currentPage, currentPath, currentRecordId, and query params from window.location on every message
NewdetectPageContext() exported from @syncagent/js — works in React, Vue, Angular, Next.js, and vanilla JS (SSR-safe)
NewautoDetectPage config option (default: true) — set false to disable auto-detection
NewContext sent as dedicated field in request body and injected into AI system prompt as structured USER CONTEXT section
FixMongoDB parseFilter now converts ALL ObjectId-like strings (not just _id) — fixes multi-tenant filters returning 0 results
FixMongoDB aggregate now parses ObjectId strings in $match stages — fixes scoped aggregations returning empty
FixAll SQL connectors (PostgreSQL, MySQL, SQLite, MSSQL, Supabase) now apply $match stages as WHERE clauses in aggregations
FixSupabase count now handles operator filters ($gt, $lt, etc.) instead of silently dropping them
Fix7 advanced tools now respect mandatory filter — field_distribution, find_duplicates, sample_data, collection_stats, database_overview, get_distinct_values, copy_collection
Fixraw_query and rename_collection disabled in multi-tenant mode — they bypassed tenant scoping
Fixcross_search no longer uses $regex (broke SQL connectors) — uses universal scoped approach
FixDead code bug: __sa_data emission was after a return statement — onData callback now fires correctly
v0.3.1
April 5, 2026Tools-only mode — use the agent with only your custom tools, no database required
NewtoolsOnly config option — disables all built-in database tools so the agent only calls your custom tools
NewconnectionString is now optional when toolsOnly is enabled — no DB connection needed
NewDedicated tools-only system prompt that instructs the agent to exclusively use client-provided tools
NewServer skips DB connection, schema discovery, and schema refresh entirely in tools-only mode
ImprovedEdge case handling — toolsOnly without tools gracefully falls back to requiring connectionString
ImprovedDocumentation updated across all SDK READMEs and the docs page with tools-only examples
v0.3.0

FixTypeScript intellisense — full autocomplete and Go-to-Definition now works out of the box
Fixpackage.json exports pointing to wrong file paths (.cjs → .js to match tsup output)
NewtypesVersions fallback for all moduleResolution settings (node, node16, nodenext, bundler)
NewConditional types in exports — separate .d.mts for ESM and .d.ts for CJS
ImprovedSchema cache TTL reduced from 1 hour to 5 minutes for faster schema change detection
NewAuto schema refresh — when a tool hits a 'collection not found' error, the agent automatically re-discovers the schema and retries

NewEmpty response detection with automatic retry using trimmed context
NewonAction callback in JS SDK for context_warning, context_compacted, force_compact events
NewClient-side Compact History button wired to server-driven alerts
