安装
标题: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-sqlbunx cap syncimport { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';connect
Section titled “连接”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
Section titled “断开连接”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
Section titled “获取服务器信息”获取HTTP服务器端口和令牌以进行直接通信。
import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';
const info = await CapgoCapacitorFastSql.getServerInfo({ database: 'myapp' });console.log('Server port:', info.port);execute
执行通过Capacitor桥执行一个SQL查询(适用于简单的查询)。 对于大型数据集的更好性能,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
beginTransaction开始一个数据库事务。
import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';
await CapgoCapacitorFastSql.beginTransaction({ database: 'myapp' });// Execute multiple operationsawait CapgoCapacitorFastSql.commitTransaction({ database: 'myapp' });commitTransaction
commitTransaction提交当前事务。
import { CapgoCapacitorFastSql } from '@capgo/capacitor-fast-sql';
await CapgoCapacitorFastSql.commitTransaction({ database: 'myapp' });rollbackTransaction
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
标题:配置 Web为 sql.js WASM 模块配置 Web 特定的选项。
调用此 在开始开发新功能之前, 在首次 connect() 加载 sql.js 从本地打包路径而不是默认 CDN。这在 iOS 和 Android 上是无操作的。
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
标题:类型参考SQLConnectionOptions
标题: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
SQLValue插件支持的SQL值类型。
export type SQLValue = string | number | boolean | null | Uint8Array;SQLResult
SQLResultSQL查询执行的结果。
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
IsolationLevel事务隔离级别。
export enum IsolationLevel { ReadUncommitted = 'READ UNCOMMITTED', ReadCommitted = 'READ COMMITTED', RepeatableRead = 'REPEATABLE READ', Serializable = 'SERIALIZABLE',}WebConfig
WebConfig用于sql.js WASM模块的Web平台配置。请与 configureWeb() 从本地打包路径加载 sql.js 代替默认的 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
SQLRow 部分SQL 行结果 - 值按列名索引。
export interface SQLRow { [column: string]: SQLValue;}真实数据来源
真实数据来源部分本页面由插件生成的。 src/definitions.ts当公共 API 在上游发生变化时,请重新同步。
