angular-sqlite-app-refactor's Issues

Using the refactor code in a service

I had two issues in implementing the refactor code. Maybe the documentation or test app could be expanded to include these.

  1. The sql calls are contained in a service, and not in the page.ts
  2. The initial page is a list page that queries the database. The query must not run before the database is connected and opened.

This is how I solved these.

In app.component.ts:

      this.databaseService.dbReady.subscribe(isReady => {
        if (isReady) {
          SplashScreen.hide();
 ...```

In databaseService.service.ts:
```  dbReady = new BehaviorSubject(false);
...
  async init() {
    await this._SQLiteService.initializePlugin().then(retInit => {
      this.initPlugin = retInit;
    })
    this.db = await this._SQLiteService.retrieveConnection("example");
    if(this.db == null) {
      this.db = await this._SQLiteService.createConnection("example");
    }
    let ret: any = await this.db.open();
    let retExe = await this.db.execute(createSchema);
    this.dbReady.next(true);
  }

All other calls to the database use "this.db." instead of "db.".

Then in list.page.ts:

this.databaseService.dbReady.subscribe(isReady => {
        if (isReady) {
          this.getList();
        ...
