Ionic capacitor Sqlite源码可以在github上查看https://github.com/capacitor-community/sqlite，目前中文的资料比较少，以前主要是Cordova的Sqlite，capacitor比较新，不过好在github上的资料也还算比较全面

capacitor 的Sqlite支持Android, iOS, Web和Electron,在web平台测试了一下，生成的的数据库可以在chrome下开发工具里面查看，在Application(应用)栏，Storage, IndexedDB, jeepSqliteStore

运行(await this.sqliteConnection.checkConnectionsConsistency()).result之前要先运行 await this.sqliteConnection.initWebStore();

否则console中可以看到报了以下错误

node_modules_capacit…ist_esm_web_js.js:2 ERROR 

Error: The jeep-sqlite element is not present in the DOM! Please check the @capacitor-community/sqlite documentation for instructions regarding the web platform.
