Background Geolocation Tracking with Ionic 5+ PouchDB

Background Geolocation Tracking with Ionic 5+ PouchDB

Step 1
Create a new Ionic project.

npm install -g ionic@latest
ionic start ionic4-background-geo-pouchdb blank

Step 2
Install plugin and dependencies.

// geolocation tracking
ionic cordova plugin add @mauron85/cordova-plugin-background-geolocation
npm install --save @ionic-native/background-geolocation

// sqlite as storage without limits
ionic cordova plugin add cordova-sqlite-storage
npm install @ionic-native/sqlite

// pouchDB
npm install pouchdb-adapter-cordova-sqlite --save
npm install pouchdb --save

That's all what you need to install in order to start using PouchDB with SQLite in your Ionic app without any storage limits.

Step 3
Create Couch Provider

import { Injectable } from '@angular/core';
import * as PouchDB from 'pouchdb/dist/pouchdb';
import * as cordovaSqlitePlugin from 'pouchdb-adapter-cordova-sqlite/dist/pouchdb.cordova-sqlite';

  providedIn: 'root'
export class CouchApiService {

  constructor() {

  addEntry(name, entry) {
     const db = new PouchDB(name + '.db',
                auto_compaction: true,
                adapter: 'cordova-sqlite',
                iosDatabaseLocation: 'Library',
                androidDatabaseImplementation: 2,
                timeout: 15000,
                batch_size: 500


Step 4
Add to app.module.ts

import { BackgroundGeolocation } from "@ionic-native/background-geolocation/ngx";
import { CouchApiService } from './providers/couch-api.service';

providers: [

import {
} from "@ionic-native/background-geolocation/ngx";

import * as PouchDB from 'pouchdb/dist/pouchdb';
import * as cordovaSqlitePlugin from 'pouchdb-adapter-cordova-sqlite/dist/pouchdb.cordova-sqlite';

import { CouchApiService } from '../providers/couch-api.service';

  selector: 'app-home',
  templateUrl: '',
  styleUrls: ['']
export class HomePage{

    	private readonly couchApiService: CouchApiService, 
    	private readonly backgroundGeolocation: BackgroundGeolocation
    ) {
    startBackgroundGeolocation() {
    const config: BackgroundGeolocationConfig = {
      desiredAccuracy: 10,
      stationaryRadius: 20,
      distanceFilter: 100,
      debug: true, //  enable this hear sounds for background-geolocation life-cycle.
      stopOnTerminate: false // enable this to clear background location settings when the app terminates

    this.backgroundGeolocation.configure(config).then(() => {

          .subscribe((location: any) => {
            if (location.speed == undefined) {
              location.speed = 0;
            // add location into pouchDB
            this.couchApiService.addEntry('MyDatabaseName', location)
                .then(data => {
                  this.backgroundGeolocation.finish(); // FOR IOS ONLY
                .catch(error => {
                  this.backgroundGeolocation.finish(); // FOR IOS ONLY

            // IMPORTANT:  You must execute the finish method here to inform the native plugin that you're finished,
            // and the background-task may be completed.  You must do this regardless if your operations are successful or not.
            // IF YOU DON'T, ios will CRASH YOUR APP for spending too much time in the background.

    // start recording location

Step 5
Add platform

ionic cordova platform add android
ionic cordova prepare android

ionic cordova platform add ios
ionic cordova prepare ios
