## Type Alignment with Go
Types in `src/common/types.ts` match `pkg/common/types.go`:
- **Operator**: `eq`, `neq`, `gt`, `gte`, `lt`, `lte`, `like`, `ilike`, `in`, `contains`, `startswith`, `endswith`, `between`, `between_inclusive`, `is_null`, `is_not_null`
- **FilterOption**: `column`, `operator`, `value`, `logic_operator` (AND/OR)
- **Options**: `columns`, `omit_columns`, `filters`, `sort`, `limit`, `offset`, `preload`, `customOperators`, `computedColumns`, `parameters`, `cursor_forward`, `cursor_backward`, `fetch_row_number`
- **PreloadOption**: `relation`, `table_name`, `columns`, `omit_columns`, `sort`, `filters`, `where`, `limit`, `offset`, `updatable`, `recursive`, `computed_ql`, `primary_key`, `related_key`, `foreign_key`, `recursive_child_key`, `sql_joins`, `join_aliases`
- **Parameter**: `name`, `value`, `sequence?`
- **Metadata**: `total`, `count`, `filtered`, `limit`, `offset`, `row_number?`
- **APIError**: `code`, `message`, `details?`, `detail?`
---
## HeaderSpec Header Mapping
Maps Options to HTTP headers per Go `restheadspec/headers.go`:
| Header | Options field | Format |
|--------|--------------|--------|
| `X-Select-Fields` | `columns` | comma-separated |
| `X-Not-Select-Fields` | `omit_columns` | comma-separated |
| `X-FieldFilter-{col}` | `filters` (eq, AND) | value |
| `X-SearchOp-{op}-{col}` | `filters` (AND) | value |
| `X-SearchOr-{op}-{col}` | `filters` (OR) | value |
| `X-Sort` | `sort` | `+col` (asc), `-col` (desc) |
| `X-Limit` | `limit` | number |
| `X-Offset` | `offset` | number |
| `X-Cursor-Forward` | `cursor_forward` | string |
| `X-Cursor-Backward` | `cursor_backward` | string |
| `X-Preload` | `preload` | `Rel:col1,col2` pipe-separated |
| `X-Fetch-RowNumber` | `fetch_row_number` | string |
| `X-CQL-SEL-{col}` | `computedColumns` | expression |
| `X-Custom-SQL-W` | `customOperators` | SQL AND-joined |
Complex values use `ZIP_` + base64 encoding.
HTTP methods: GET=read, POST=create, PUT=update, DELETE=delete.
---
## Build & Test
```bash
pnpm install
pnpm run build # vite library mode → dist/
pnpm run test # vitest
pnpm run lint # eslint
```
**Config files:** `tsconfig.json` (ES2020, strict, bundler), `vite.config.ts` (lib mode, dts via vite-plugin-dts)
**Externals:** `uuid`, `semver`
---
## Remaining Work
- **Phase 6 — MQTT Client**: Topic-based CRUD over MQTT (optional/future)
- **Phase 7 — Cache**: In-memory response cache with TTL, key = URL + options hash, auto-invalidation on CUD, `skipCache` flag
- **Phase 8 — TanStack Query Integration**: Query/mutation hooks wrapping each client, query key factories, automatic cache invalidation
- **Phase 9 — React Hooks**: `useResolveSpec`, `useHeaderSpec`, `useWebSocket` hooks with provider context, loading/error states
- ESLint config may need updating for new folder structure

# ResolveSpec JS
TypeScript client library for ResolveSpec APIs. Supports body-based REST, header-based REST, and WebSocket protocols.
## Install
```bash
pnpm add @warkypublic/resolvespec-js
```
## Clients
| Client | Protocol | Singleton Factory |
| --- | --- | --- |
| `ResolveSpecClient` | REST (body-based) | `getResolveSpecClient(config)` |
| `HeaderSpecClient` | REST (header-based) | `getHeaderSpecClient(config)` |
| `WebSocketClient` | WebSocket | `getWebSocketClient(config)` |
All clients use the class pattern. Singleton factories return cached instances keyed by URL.
## REST Client (Body-Based)
Options sent in JSON request body. Maps to Go `pkg/resolvespec`.
```typescript
import { ResolveSpecClient, getResolveSpecClient } from '@warkypublic/resolvespec-js';
// Class instantiation
const client = new ResolveSpecClient({ baseUrl: 'http://localhost:3000', token: 'your-token' });
// Or singleton factory (returns cached instance per baseUrl and effective headers)
const client = getResolveSpecClient({ baseUrl: 'http://localhost:3000', token: 'your-token' });
// Read with filters, sort, pagination
const result = await client.read('public', 'users', undefined, {
columns: ['id', 'name', 'email'],
filters: [{ column: 'status', operator: 'eq', value: 'active' }],
sort: [{ column: 'name', direction: 'asc' }],
limit: 10,
offset: 0,
preload: [{ relation: 'Posts', columns: ['id', 'title'] }],
});
// Read by ID
const user = await client.read('public', 'users', 42);
// Create
const created = await client.create('public', 'users', { name: 'New User' });
// Update
await client.update('public', 'users', { name: 'Updated' }, 42);
// Delete
await client.delete('public', 'users', 42);
// Metadata
const meta = await client.getMetadata('public', 'users');
```
## HeaderSpec Client (Header-Based)
Options sent via HTTP headers. Maps to Go `pkg/restheadspec`.
```typescript
import { HeaderSpecClient, getHeaderSpecClient } from '@warkypublic/resolvespec-js';
const client = new HeaderSpecClient({ baseUrl: 'http://localhost:3000', token: 'your-token' });
// Or: const client = getHeaderSpecClient({ baseUrl: 'http://localhost:3000', token: 'your-token' });
// GET with options as headers
const result = await client.read('public', 'users', undefined, {
columns: ['id', 'name'],
filters: [
{ column: 'status', operator: 'eq', value: 'active' },
{ column: 'age', operator: 'gte', value: 18, logic_operator: 'AND' },
],
sort: [{ column: 'name', direction: 'asc' }],
limit: 50,
preload: [{ relation: 'Department', columns: ['id', 'name'] }],
});
// POST create
await client.create('public', 'users', { name: 'New User' });
// PUT update
await client.update('public', 'users', '42', { name: 'Updated' });
// DELETE
await client.delete('public', 'users', '42');
```
### Header Mapping
| Header | Options Field | Format |
| --- | --- | --- |
| `X-Select-Fields` | `columns` | comma-separated |
| `X-Not-Select-Fields` | `omit_columns` | comma-separated |
| `X-FieldFilter-{col}` | `filters` (eq, AND) | value |
| `X-SearchOp-{op}-{col}` | `filters` (AND) | value |
| `X-SearchOr-{op}-{col}` | `filters` (OR) | value |
| `X-Sort` | `sort` | `+col` asc, `-col` desc |
| `X-Limit` / `X-Offset` | `limit` / `offset` | number |
| `X-Cursor-Forward` | `cursor_forward` | string |
| `X-Cursor-Backward` | `cursor_backward` | string |
| `X-Preload` | `preload` | `Rel:col1,col2` pipe-separated |
| `X-Fetch-RowNumber` | `fetch_row_number` | string |
| `X-CQL-SEL-{col}` | `computedColumns` | expression |
| `X-Custom-SQL-W` | `customOperators` | SQL AND-joined |
| `X-Preload-Where` | `preload[].where` | applies to all preloads in `X-Preload`; differing wheres go to `X-Preload-{n}` + `X-Preload-{n}-Where` |
| `X-Expand` | `expand` | `Rel:col1,col2` pipe-separated (LEFT JOIN) |
| `X-Custom-SQL-Join` | `custom_sql_joins` | JOIN clauses, pipe-separated |
| `X-Custom-SQL-Or` | `custom_sql_or` | SQL OR-joined |
| `X-SearchCols` | `search_columns` | comma-separated |
| `X-AdvSQL-{col}` | `advanced_sql` | column -> SQL |
| `X-SpatialFilter-{col}` | `filters` (`st_dwithin`, `st_*`, `bbox`) | JSON `{op,value,logic}` |
| `X-VectorFilter-{col}` | `filters` (`l2_within`, `cosine_within`, `ip_within`) | JSON `{op,value,logic}` |
| `X-Vector-Search-{col}` / `-Vector` / `-As` / `-Dir` | `vector_search` | metric / JSON array / alias / asc\|desc |
| `X-Clean-JSON` | `clean_json` | bool |
| `X-Distinct` | `distinct` | bool |
| `X-SkipCount` / `X-SkipCache` | `skip_count` / `skip_cache` | bool |
| `X-PKRow` | `pk_row` | string |
| `X-SimpleApi` / `X-DetailApi` / `X-Syncfusion` | `response_format` | `simple` \| `detail` \| `syncfusion` |
| `X-Single-Record-As-Object` | `single_record_as_object` | bool (server default true) |
| `X-Transaction-Atomic` | `atomic_transaction` | bool |
| `X-Files` | `xfiles` | JSON, sent as `ZIP_` base64 |
Extended fields live on `HeaderSpecOptions` (extends `Options`); `vector_search` is on `Options`.
### Utility Functions
```typescript
import { buildHeaders, encodeHeaderValue, decodeHeaderValue } from '@warkypublic/resolvespec-js';
const headers = buildHeaders({ columns: ['id', 'name'], limit: 10 });
// => { 'X-Select-Fields': 'id,name', 'X-Limit': '10' }
const encoded = encodeHeaderValue('complex value'); // 'ZIP_...'
const decoded = decodeHeaderValue(encoded); // 'complex value'
```
## WebSocket Client
Real-time CRUD with subscriptions. Maps to Go `pkg/websocketspec`.
```typescript
import { WebSocketClient, getWebSocketClient } from '@warkypublic/resolvespec-js';
const ws = new WebSocketClient({
url: 'ws://localhost:8080/ws',
reconnect: true,
heartbeatInterval: 30000,
});
// Or: const ws = getWebSocketClient({ url: 'ws://localhost:8080/ws' });
await ws.connect();
// CRUD
const users = await ws.read('users', { schema: 'public', limit: 10 });
const created = await ws.create('users', { name: 'New' }, { schema: 'public' });
await ws.update('users', '1', { name: 'Updated' });
await ws.delete('users', '1');
// Subscribe to changes
const subId = await ws.subscribe('users', (notification) => {
console.log(notification.operation, notification.data);
});
// Unsubscribe
await ws.unsubscribe(subId);
// Events
ws.on('connect', () => console.log('connected'));
ws.on('disconnect', () => console.log('disconnected'));
ws.on('error', (err) => console.error(err));
ws.disconnect();
```
## Types
All types align with Go `pkg/common/types.go`.
### Key Types
```typescript
interface Options {
columns?: string[];
omit_columns?: string[];
filters?: FilterOption[];
sort?: SortOption[];
limit?: number;
offset?: number;
preload?: PreloadOption[];
customOperators?: CustomOperator[];
computedColumns?: ComputedColumn[];
parameters?: Parameter[];
cursor_forward?: string;
cursor_backward?: string;
fetch_row_number?: string;
}
interface FilterOption {
column: string;
operator: Operator | string;
value: any;
logic_operator?: 'AND' | 'OR';
}
// Operators: eq, neq, gt, gte, lt, lte, like, ilike, in,
// contains, startswith, endswith, between,
// between_inclusive, is_null, is_not_null
interface APIResponse<T> {
success: boolean;
data: T;
metadata?: Metadata;
error?: APIError;
}
```
## Build
```bash
pnpm install
pnpm run build # dist/index.js (ES) + dist/index.cjs (CJS) + .d.ts
pnpm run test # vitest
pnpm run lint # eslint
```

### Custom HTTP headers
Both `ResolveSpecClient` and `HeaderSpecClient` (including their factory functions)
accept `headers` in `ClientConfig` and send them on every HTTP request:
```typescript
const client = new ResolveSpecClient({
baseUrl: 'http://localhost:3000',
token: 'your-token',
headers: { 'X-Tenant': 'acme' },
});
```
Header names are merged case-insensitively. Custom headers override the default
`Content-Type`; a supplied `token` overrides custom `Authorization`, and HeaderSpec
query options override matching custom query headers. Without a token, custom
`Authorization` is preserved. Configuration is copied at construction; create or
retrieve a client with new configuration to change headers. Factory clients are
cached by URL and effective headers, keeping different tenants and tokens separate.
Grid adapters must forward `dataSourceOptions.headers` to this `headers` option.
