开始使用

安装

您可以使用我们的 AI 助手设置来安装插件。将 Capgo 技能添加到您的 AI 工具中，使用以下命令:

npx skills add https://github.com/Cap-go/capgo-skills --skill capacitor-plugins

然后使用以下提示:

Use the `capacitor-plugins` skill from `Cap-go/capgo-skills` to install the `@capgo/capacitor-fast-sql` plugin in my project.

如果您prefer手动设置，安装插件并运行以下命令并遵循以下平台特定说明：

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

导入

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

API 概述

connect

初始化数据库连接并启动 HTTP 服务器。

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

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

disconnect

关闭数据库连接并停止 HTTP 服务器。

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

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

getServerInfo

获取 HTTP 服务器端口和令牌进行直接通信。

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

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

execute

通过 Capacitor 桥执行 SQL 查询（适用于简单查询）。 对于大数据集的更好性能，使用 HTTP 协议直接通过 SQLConnection 类。

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

开始数据库事务。

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

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

commitTransaction

提交当前事务。

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

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

rollbackTransaction

回滚当前事务。

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

调用此

在开始工作新功能之前 首次 第一步 connect() 类型参考

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' });

类型参考

SQLConnectionOptions

数据库连接选项

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

插件支持的SQL值类型

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

SQLResult

事务隔离级别

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

复制到剪贴板

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

WebConfig

sql.js WASM 模块的 Web 平台配置。使用 configureWeb() 以本地打包路径加载 sql.js 代替默认 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 行结果 - 值按列名索引。

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

真实数据来源

重新同步公共 __CAPGO_KEEP_0__ 时更改上游。 src/definitions.ts重新同步时，应根据上游的公共API变动。
