@cereusdb/standard

Standard CereusDB browser package. Everything in @cereusdb/minimal, plus PROJ-backed ST_Transform and CRS-aware reprojection support.

This package includes browser object stores for ranged remote Parquet reads and S3/GCS/Azure/HTTP providers.

Install

npm install @cereusdb/standard

SQL function availability

Current runtime surface:

• 131 runtime ST_* names
• 0 runtime RS_* names

Included function families:

• Everything from @cereusdb/minimal: core SedonaDB functions, geo functions, GEOS predicates/operations, relation joins, distance joins, and ST_KNN.
• PROJ-backed CRS transformation with ST_Transform.

Examples of available functions:

• Core and geo: ST_Point, ST_GeomFromWKT, ST_AsText, ST_SRID, ST_Buffer, ST_Distance, ST_DWithin, ST_AsGeoJSON
• GEOS: ST_Contains, ST_Within, ST_Crosses, ST_Touches, ST_Union, ST_Difference, ST_MakeValid, ST_Polygonize
• PROJ: ST_Transform

Not included in this package:

• S2 geography kernels
• Raster RS_* functions

Object storage support

Browser object stores are included in @cereusdb/standard. Use registerObjectStores() to configure http, s3, gcs, or azure providers, then registerParquetTable() to register an exact Parquet object or provider-backed prefix.

JS / TS API

Exports:

• CereusDB
• CereusDBOptions
• ObjectStoreRegistryConfig
• ObjectStoreConfig
• ObjectStoreProvider
• RegisterParquetTableOptions
• RasterFormat
• QueryResult

Main types:

type RasterFormat = 'geotiff' | 'tiff';
type ObjectStoreProvider = 'http' | 's3' | 'gcs' | 'azure';

interface CereusDBOptions {
  wasmUrl?: string;
  wasmSource?:
    | RequestInfo
    | URL
    | Response
    | BufferSource
    | WebAssembly.Module
    | Promise<Response>;
  objectStores?: ObjectStoreRegistryConfig;
}

interface ObjectStoreRegistryConfig {
  maxConcurrency?: number;
  stores: ObjectStoreConfig[];
}

interface ObjectStoreConfig {
  name?: string;
  provider: ObjectStoreProvider;
  url: string;
  options?: Record<string, string | number | boolean>;
}

interface RegisterParquetTableOptions {
  fileExtension?: string;
  targetPartitions?: number;
}

Main API:

class CereusDB {
  static create(options?: CereusDBOptions): Promise<CereusDB>;
  sql(query: string): Promise<Uint8Array>;
  sqlJSON(query: string): Promise<Record<string, unknown>[]>;
  registerRemoteParquet(name: string, url: string): Promise<void>;
  registerObjectStores(config: ObjectStoreRegistryConfig): void;
  registerParquetTable(
    name: string,
    url: string,
    options?: RegisterParquetTableOptions,
  ): Promise<void>;
  registerFile(name: string, file: File): Promise<void>;
  registerGeoJSON(name: string, geojson: string | object): void;
  registerRaster(name: string, data: BufferSource, format: RasterFormat): void;
  registerGeoTIFF(name: string, data: BufferSource): void;
  dropTable(name: string): void;
  tables(): string[];
  version(): string;
}

API notes:

• sql() returns Arrow IPC bytes as Uint8Array.
• sqlJSON() returns parsed JSON rows.
• registerFile() supports .parquet, .geoparquet, .geojson, and .json in this package.
• registerObjectStores() and registerParquetTable() support browser-backed ranged Parquet reads for http, s3, gcs, and azure providers.
• S3 temporary credentials use access_key_id, secret_access_key, and token, where token is the STS SessionToken.
• S3-compatible endpoints can be configured with endpoint; use allow_http: true for local HTTP endpoints such as MinIO or LocalStack.
• registerRaster() and registerGeoTIFF() are part of the shared wrapper, but raster registration requires @cereusdb/full.

Example

import { CereusDB } from '@cereusdb/standard';

const db = await CereusDB.create();

const rows = await db.sqlJSON(`
  SELECT ST_AsText(
    ST_Transform(
      ST_GeomFromWKT('POINT(13.4 52.5)'),
      'EPSG:4326',
      'EPSG:3857'
    )
  ) AS geom
`);

console.log(rows);
