Getting Started

Install

bun add @capgo/capacitor-fast-sql
bunx cap sync

Import

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

API Overview

connect

Initialize the database connection and start the HTTP server.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

const conn = await CapgoCapacitorFastSql.connect({ database: 'myapp' });
console.log('Connected on port:', conn.port);

disconnect

Close database connection and stop the HTTP server.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

await CapgoCapacitorFastSql.disconnect({ database: 'myapp' });

getServerInfo

Get the HTTP server port and token for direct communication.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

const info = await CapgoCapacitorFastSql.getServerInfo({ database: 'myapp' });
console.log('Server port:', info.port);

execute

Execute a SQL query via Capacitor bridge (for simple queries). For better performance with large datasets, use the HTTP protocol directly via SQLConnection class.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

const result = await CapgoCapacitorFastSql.execute({
  database: 'myapp',
  statement: 'SELECT * FROM users WHERE age > ?',
  params: [18]
});
console.log('Rows:', result.rows);

beginTransaction

Begin a database transaction.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

await CapgoCapacitorFastSql.beginTransaction({ database: 'myapp' });
// Execute multiple operations
await CapgoCapacitorFastSql.commitTransaction({ database: 'myapp' });

commitTransaction

Commit the current transaction.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

await CapgoCapacitorFastSql.commitTransaction({ database: 'myapp' });

rollbackTransaction

Rollback the current transaction.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

try {
  await CapgoCapacitorFastSql.beginTransaction({ database: 'myapp' });
  // Operations...
  await CapgoCapacitorFastSql.commitTransaction({ database: 'myapp' });
} catch (error) {
  await CapgoCapacitorFastSql.rollbackTransaction({ database: 'myapp' });
}

configureWeb

Configure web-specific options for the sql.js WASM module.

Call this before the first connect() call to load sql.js from a locally bundled path instead of the default CDN. This method is a no-op on iOS and Android.

import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';

// Configure once at app startup (web only)
await CapgoCapacitorFastSql.configureWeb({
  sqlJsUrl: '/assets/sql-wasm.js',
  wasmUrl: '/assets/sql-wasm.wasm',
});
const db = await FastSQL.connect({ database: 'myapp' });

Type Reference

SQLConnectionOptions

Database connection options.

export interface SQLConnectionOptions {
  /**
   * Database name (file will be created in app data directory)
   */
  database: string;

  /**
   * Enable encryption (iOS/Android only)
   */
  encrypted?: boolean;

  /**
   * Encryption key (required if encrypted is true)
   */
  encryptionKey?: string;

  /**
   * Read-only mode
   */
  readOnly?: boolean;
}

SQLValue

SQL value types supported by the plugin.

export type SQLValue = string | number | boolean | null | Uint8Array;

SQLResult

Result of a SQL query execution.

export interface SQLResult {
  /**
   * Rows returned by the query (for SELECT statements)
   */
  rows: SQLRow[];

  /**
   * Number of rows affected by the query (for INSERT/UPDATE/DELETE)
   */
  rowsAffected: number;

  /**
   * ID of the last inserted row (for INSERT statements with auto-increment)
   */
  insertId?: number;
}

IsolationLevel

Transaction isolation levels.

export enum IsolationLevel {
  ReadUncommitted = 'READ UNCOMMITTED',
  ReadCommitted = 'READ COMMITTED',
  RepeatableRead = 'REPEATABLE READ',
  Serializable = 'SERIALIZABLE',
}

WebConfig

Web platform configuration for the sql.js WASM module. Use with configureWeb() to load sql.js from a locally bundled path instead of the default CDN.

export interface WebConfig {
  /**
   * URL to the sql.js JavaScript file (`sql-wasm.js`).
   * When omitted, the plugin loads from the cdnjs CDN.
   * @example '/assets/sql-wasm.js'
   */
  sqlJsUrl?: string;

  /**
   * URL to the sql.js WebAssembly binary (`sql-wasm.wasm`).
   * When omitted, the plugin loads from the cdnjs CDN.
   * @example '/assets/sql-wasm.wasm'
   */
  wasmUrl?: string;
}

SQLRow

SQL row result - values indexed by column name.

export interface SQLRow {
  [column: string]: SQLValue;
}
