javascript - Setting up and inserting data in PouchDb on Ionic 2 -


hi guys im new ionic 2,

but know js/ts , fun stuff already. want use pouchdb in ionic app here home.ts file:

import { component } '@angular/core';  import * pouchdb 'pouchdb';   import cordovasqliteplugin 'pouchdb-adapter-cordova-sqlite';  @component({   selector: 'page-home',   templateurl: 'home.html' }) export class homepage { }   pouchdb.plugin(cordovasqliteplugin); var db = new pouchdb('test', { adapter: 'cordova-sqlite' });    function setdata(data) {  var todo = {     title: data,     completed: false   };   db.post(todo, function callback(err, result) {     if (!err) {       console.log('successfully posted todo!');     }   }); }    function getdata() {   console.log(db.alldocs); }

here first problem var db = new pouchdb....is no fuction when put in on startup function error because "setdata" function doesnt know "db" is. how can fix that? , importing stuff right?

next question have import stuff in app.module.ts file too? need provider?

import { ngmodule, errorhandler } '@angular/core'; import { browsermodule } '@angular/platform-browser'; import { ionicapp, ionicmodule, ionicerrorhandler } 'ionic-angular'; import { myapp } './app.component';  import { aboutpage } '../pages/about/about'; import { contactpage } '../pages/contact/contact'; import { homepage } '../pages/home/home'; import { tabspage } '../pages/tabs/tabs'; import { statusbar } '@ionic-native/status-bar'; import { splashscreen } '@ionic-native/splash-screen';    @ngmodule({   declarations: [     myapp,     aboutpage,     contactpage,     homepage,     tabspage   ],   imports: [     browsermodule,     ionicmodule.forroot(myapp),    ],   bootstrap: [ionicapp],   entrycomponents: [     myapp,     aboutpage,     contactpage,     homepage,     tabspage   ],   providers: [     statusbar,     splashscreen,     {provide: errorhandler, useclass: ionicerrorhandler}] }) export class appmodule {}
