How to use it on ionic existing project

[jpujol880807]

I have this configuration
ionic/app-scripts : 3.1.2
Cordova Platforms : android 6.3.0
Ionic Framework : ionic-angular 3.9.2
Node: 6.11.5
Npm: 3.10.10
System: Windows 10
I'm trying to use the npm package on existing project and it works well on the browser, but it doesn't render the map on android devices, i'm missing some step to make it work?
I added
import 'promise-polyfill';
import 'whatwg-fetch';
and installed them with npm

Hello,
I tested the sample with your configuration seems working without --prod to ionic cordova build android. I will investigate on this issue.

EDIT: I found the problem, the npm packages that I made were using sql.js 0.4.0 I updated it to 0.5.0 but another bug came from this version webpack was throwing a heap out of memory error when building with --prod so I found a fix, this issue is related to webpack/ionic-app-script : https://github.com/ionic-team/ionic-app-scripts/issues/1036.

I prefer adding "config": { "ionic_source_map_type": "cheap-source-map" } to the package.json than using node --max-old-space-size=8192 in every build.

In definitive update the npm package npm i leaflet-tilelayer-mbtiles-ts@latest and add :
"config": { "ionic_source_map_type": "cheap-source-map" }, to your package.json

When I added it manually, it works well at iOS Simulator. But it doesn't work at real Android device like issue #6 . How about you, @jpujol880807 ?
