Cordova/PhoneGap sqlite storage adapter

Native interface to sqlite in a Cordova/PhoneGap plugin for Android, iOS, Windows Universal (8.1), Amazon Fire-OS, and WP(7/8) with API similar to HTML5/Web SQL API.

License for Android, Windows Universal (8.1), Amazon Fire-OS, and WP(7/8) versions: MIT or Apache 2.0

License for iOS version: MIT only

Status

Cordova sqlite storage (0.7.6) published in PhoneGap Build
Windows Universal (8.1) version is in pre/alpha state:
- No background processing
- Database close and delete operations not yet implemented
- Not all Windows CPU targets are supported by automatic installation
- Does not work properly with Cordova CLI due to CB-8866. Please install using litehelpers / cordova-windows_allcpufix and plugman as described below.
Status for the other target platforms:
- Android: now using the sqlite4java library (sqlite 3.8.7 embedded)
- iOS: sqlite 3.8.9 embedded
- WP7: possible to build from C#, as specified by plugin.xml - NOT TESTED
- WP8: performance/stability issues have been reported with the CSharp-SQLite library. Windows (universal) platform is recommended for the future.
API to open the database may be changed somewhat to be more streamlined. Transaction and single-statement query API will NOT be changed.

Announcements

Highlights

Drop-in replacement for HTML5 SQL API, the only change should be window.openDatabase() --> sqlitePlugin.openDatabase()
Failure-safe nested transactions with batch processing optimizations
As described in this posting:
- Keeps sqlite database in a user data location that is known; can be reconfigured (iOS version); and synchronized to iCloud by default (iOS version; can be disabled as described below).
- No 5MB maximum, more information at: http://www.sqlite.org/limits.html
Android is supported back to SDK 10 (a.k.a. Gingerbread, Android 2.3.3); support for older versions is available upon request.
Pre-populated database option (usage described below)

Known issues

Issue reported with PhoneGap Build Hydration.
For some reason, PhoneGap Build may fail to build the iOS version unless the name of the app starts with an uppercase and contains no spaces (see #243; Wizcorp/phonegap-facebook-plugin#830; phonegap/build#431).
Multi-page apps are not supported and known to be broken on Android and Amazon Fire-OS.
Using web workers is currently not supported and known to be broken on Android and Amazon Fire-OS.
Triggers have only been tested on iOS, known to be broken on Android (in case sqlite4java is disabled) and Amazon Fire-OS.
INSERT statement that affects multiple rows (due to SELECT cause or using triggers, for example) does not report proper rowsAffected on Android (in case sqlite4java is disabled) or Amazon Fire-OS.
On Windows (8.1), rowsAffected can be wrong when there are multiple levels of nesting of INSERT statements.
Memory issue observed when adding a large number of records on Android and Amazon Fire-OS, due to JSON implementation (ref: #18)
A stability issue was reported on the iOS version when in use together with SockJS client such as pusher-js at the same time (see #196). The workaround is to call sqlite functions and SockJS client functions in separate ticks (using setTimeout with 0 timeout).

Other limitations

The db version, display name, and size parameter values are not supported and will be ignored.
This plugin will not work before the callback for the "deviceready" event has been fired, as described in Usage. (This is consistent with the other Cordova plugins.)
The Android and Amazon Fire-OS versions cannot work with more than 100 open db files due to the threading model.
UNICODE line separator (\u2028) is currently not supported and known to be broken in iOS version.
UNICODE characters not working in WP(7/8) version
Blob type is currently not supported and known to be broken on multiple platforms.
UNICODE \u0000 (same as \0) character not working in Windows (8.1) or WP(7/8) versions
Case-insensitive matching and other string manipulations on Unicode characters, which is provided by optional ICU integration in the sqlite source and working with recent versions of Android, is not supported for any target platforms.
iOS version uses a thread pool but with only one thread working at a time due to "synchronized" database access
Large query result can be slow, also due to JSON implementation

Limited support (testing needed)

DB Triggers (as described above - known to be broken for Amazon Fire-OS)
UNICODE characters not fully tested in the Windows Universal (8.1) version

Other versions

litehelpers / Cordova-sqlcipher-adapter - supports SQLCipher for Android, iOS, and Windows (8.1)
Original version for iOS (with a different API): davibe / Phonegap-SQLitePlugin

Other SQLite adapter projects

EionRobb / phonegap-win8-sqlite - WebSQL add-on for Win8/Metro apps (perhaps with a different API), using an old version of the C++ library from SQLite3-WinRT Component (as referenced by 01org / cordova-win8)
SQLite3-WinRT Component - C++ component that provides a nice SQLite API with promises for WinJS
01org / cordova-win8 - old, unofficial version of Cordova API support for Windows 8 Metro that includes an old version of the C++ SQLite3-WinRT Component
MSOpenTech / cordova-plugin-websql - Windows 8(+) and Windows Phone 8(+) WebSQL plugin versions in C#
MetaMemoryT / websql-client - provides the same API and connects to websql-server through WebSockets.

Usage

The idea is to emulate the HTML5/Web SQL API as closely as possible. The only major change is to use window.sqlitePlugin.openDatabase() (or sqlitePlugin.openDatabase()) instead of window.openDatabase(). If you see any other major change please report it, it is probably a bug.

Opening a database

There are two options to open a database:

Recommended: var db = window.sqlitePlugin.openDatabase({name: "my.db", location: 1});
Classical: var db = window.sqlitePlugin.openDatabase("myDatabase.db", "1.0", "Demo", -1);

The new location option is used to select the database subdirectory location (iOS only) with the following choices:

0 (default): Documents - visible to iTunes and backed up by iCloud
1: Library - backed up by iCloud, NOT visible to iTunes
2: Library/LocalDatabase - NOT visible to iTunes and NOT backed up by iCloud

IMPORTANT: Please wait for the "deviceready" event, as in the following example:

// Wait for Cordova to load
document.addEventListener("deviceready", onDeviceReady, false);

// Cordova is ready
function onDeviceReady() {
  var db = window.sqlitePlugin.openDatabase({name: "my.db"});
  // ...
}

NOTE: The database file name should include the extension, if desired.

Pre-populated database

For Android, iOS, and Amazon Fire-OS (only): put the database file in the www directory and open the database like:

var db = window.sqlitePlugin.openDatabase({name: "my.db", createFromLocation: 1});

or to disable iCloud backup:

db = sqlitePlugin.openDatabase({name: "my.db", location: 2, createFromLocation: 1});

IMPORTANT NOTES:

Put the pre-populated database file in the www subdirectory. This should work well with using the Cordova CLI to support both Android & iOS versions.
The pre-populated database file name must match exactly the file name given in openDatabase. The automatic extension has been completely eliminated.
The pre-populated database file is ignored if the database file with the same name already exists in your database file location.

TIP: If you don't see the data from the pre-populated database file, completely remove your app and try it again!

Android sqlite implementation

By default, this plugin uses sqlite4java which is more efficient than the built-in Android database classes. The sqlite4java library consists of a Java part and a NDK part.

Unfortunately some app developers have encountered problems using sqlite4java with Ionic and Crosswalk. To use the built-in Android database classes instead:

var db = window.sqlitePlugin.openDatabase({name: "my.db", androidDatabaseImplementation: 2});

Workaround for Android db locking issue

Issue #193 was reported (as observed by several app developers) that on some newer versions of the Android database classes, if the app is stopped or aborted without closing the database then:

(sometimes) there is an unexpected database lock
the data that was inserted is lost.

This issue is suspected to be caused by this Android sqlite commit, which references and includes the sqlite commit at: http://www.sqlite.org/src/info/6c4c2b7dba

There is an optional workaround that simply closes and reopens the database file at the end of every transaction that is committed. The workaround is enabled by opening the database with options as follows:

var db = window.sqlitePlugin.openDatabase({name: "my.db", androidDatabaseImplementation: 2, androidLockWorkaround: 1});

This option is ignored if androidDatabaseImplementation: 2 is not specified.

IMPORTANT NOTE: This workaround is only applied when using db.transaction() or db.readTransaction(), not applied when running executeSql() on the database object.

Background processing

The threading model depends on which version is used:

For Android, Amazon Fire-OS, and WP(7/8), one background thread per db;
for iOS, background processing using a very limited thread pool (only one thread working at a time);
for Windows Universal (8.1), no background processing (for future consideration).

Sample with PRAGMA feature

This is a pretty strong test: first we create a table and add a single entry, then query the count to check if the item was inserted as expected. Note that a new transaction is created in the middle of the first callback.

// Wait for Cordova to load
document.addEventListener("deviceready", onDeviceReady, false);

// Cordova is ready
function onDeviceReady() {
  var db = window.sqlitePlugin.openDatabase({name: "my.db"});

  db.transaction(function(tx) {
    tx.executeSql('DROP TABLE IF EXISTS test_table');
    tx.executeSql('CREATE TABLE IF NOT EXISTS test_table (id integer primary key, data text, data_num integer)');

    // demonstrate PRAGMA:
    db.executeSql("pragma table_info (test_table);", [], function(res) {
      console.log("PRAGMA res: " + JSON.stringify(res));
    });

    tx.executeSql("INSERT INTO test_table (data, data_num) VALUES (?,?)", ["test", 100], function(tx, res) {
      console.log("insertId: " + res.insertId + " -- probably 1");
      console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");

      db.transaction(function(tx) {
        tx.executeSql("select count(id) as cnt from test_table;", [], function(tx, res) {
          console.log("res.rows.length: " + res.rows.length + " -- should be 1");
          console.log("res.rows.item(0).cnt: " + res.rows.item(0).cnt + " -- should be 1");
        });
      });

    }, function(e) {
      console.log("ERROR: " + e.message);
    });
  });
}

Sample with transaction-level nesting

In this case, the same transaction in the first executeSql() callback is being reused to run executeSql() again.

// Wait for Cordova to load
document.addEventListener("deviceready", onDeviceReady, false);

// Cordova is ready
function onDeviceReady() {
  var db = window.sqlitePlugin.openDatabase("Database", "1.0", "Demo", -1);

  db.transaction(function(tx) {
    tx.executeSql('DROP TABLE IF EXISTS test_table');
    tx.executeSql('CREATE TABLE IF NOT EXISTS test_table (id integer primary key, data text, data_num integer)');

    tx.executeSql("INSERT INTO test_table (data, data_num) VALUES (?,?)", ["test", 100], function(tx, res) {
      console.log("insertId: " + res.insertId + " -- probably 1");
      console.log("rowsAffected: " + res.rowsAffected + " -- should be 1");

      tx.executeSql("select count(id) as cnt from test_table;", [], function(tx, res) {
        console.log("res.rows.length: " + res.rows.length + " -- should be 1");
        console.log("res.rows.item(0).cnt: " + res.rows.item(0).cnt + " -- should be 1");
      });

    }, function(e) {
      console.log("ERROR: " + e.message);
    });
  });
}

This case will also works with Safari (WebKit), assuming you replace window.sqlitePlugin.openDatabase with window.openDatabase.

Delete a database

window.sqlitePlugin.deleteDatabase({name: "my.db", location: 1}, successcb, errorcb);

location as described above for openDatabase (iOS only)

NOTE: not implemented for Windows Universal (8.1) version.

Installing

Windows Universal target platform

IMPORTANT: The Cordova CLI currently does not support all Windows target platforms due to CB-8866. Please use plugman instead, as described here.

using plugman

make sure you have the latest version of plugman installed: npm install -g plugman
Download the cordova-windows-nufix 3.9.0-nufixpre-01 zipball (or you can clone litehelpers / cordova-windows-nufix instead)
Create your Windows Universal (8.1) project using litehelpers / cordova-windows-nufix:
- path.to.cordova-windows-nufix/bin/create.bat your_app_path your.app.id YourAppName
cd your_app_path and install plugin using plugman:
- plugman install --platform windows --project . --plugin io.litehelpers.cordova.sqlite
Put your sql program in your project www (don't forget to reference it from www\index.html and wait for deviceready event)

Then your project in CordovaApp.sln should work with "Mixed Platforms" on Windows 8.1 or Windows Phone 8.1.

NOTE: You may encounter an issue that SQLite3.winmd is not found if you try to run your project on both Windows 8.1 and Windows Phone 8.1. If you encounter this issue:

delete the Debug and Generated Files from the cordova\plugins\io.litehelpers.cordova.sqlite\src\windows\SQLite3-WinRT\SQLite3 subdirectory of your project and try it again.

This is due to keeping SQLite3.Windows.vcxproj and SQLite3.WindowsPhone.vcxproj in the same subdirectory and will be fixed soon.

using Cordova CLI

WARNING: This is still in ~~pre-alpha~~ experimental state and is currently NOT supported. Please read and follow these items very carefully.

Please make sure your Cordova tooling is updated: npm update -g cordova cordova-windows
To create a new project: cordova create MyProjectFolder com.my.project MyProject (and then cd into your project directory)
To add the plugin: cordova plugin add io.litehelpers.cordova.sqlite
To add the Windows target platform (if it does not exist): cordova platform add windows
If you are using Visual Studio Express (2013), you may have to remove the Windows 8.0 build from the Visual Studio solution.
Due to CB-8866: If you use Cordova CLI for fully-automatic installation (as described here), you cannot run the project for "Any CPU" or "Mixed Platforms". Please specify a CPU type (such as x86 or x64).

NOT RECOMMENDED: To target all CPUs (partially manual): make a clone of this project and in your clone, remove (or comment out) the items that include the SQLite3.Windows.vcxproj and SQLite3.WindowsPhone.vcxproj framework projects:

--- a/plugin.xml
+++ b/plugin.xml

Easy install with plugman tool

plugman install --platform MYPLATFORM --project path.to.my.project.folder --plugin https://github.com/litehelpers/Cordova-sqlite-storage

where MYPLATFORM is android, ios, or wp8.

A posting how to get started developing on Windows host without the Cordova CLI tool (for Android target only) is available here.

NOTE: Automatic installation for the Windows target platform is not properly supported by the plugman tool.

Easy install with Cordova CLI tool

npm install -g cordova # if you don't have cordova
cordova create MyProjectFolder com.my.project MyProject && cd MyProjectFolder # if you are just starting
cordova plugin add io.litehelpers.cordova.sqlite

You can find more details at this writeup.

WARNING: for Windows target platform please read the section above.

IMPORTANT: sometimes you have to update the version for a platform before you can build, like: cordova prepare ios

NOTE: If you cannot build for a platform after cordova prepare, you may have to remove the platform and add it again, such as:

cordova platform rm ios
cordova platform add ios

Common traps & pitfalls

The plugin class name starts with "SQL" in capital letters, but in Javascript the sqlitePlugin object name starts with "sql" in small letters.
Attempting to open a database before receiving the "deviceready" event callback.

Support

Reporting issues

If you have an issue with the plugin please check the following first:

You are using the latest version of the Plugin Javascript & platform-specific Java or Objective-C source from this repository.
You have installed the Javascript & platform-specific Java or Objective-C correctly.
You have included the correct version of the cordova Javascript and SQLitePlugin.js and got the path right.
You have registered the plugin properly in config.xml.

If you still cannot get something to work:

Make the simplest test program you can to demonstrate the issue, including the following characteristics:
- it completely self-contained, i.e. it is using no extra libraries beyond cordova & SQLitePlugin.js;
- if the issue is with adding data to a table, that the test program includes the statements you used to open the database and create the table;
- if the issue is with retrieving data from a table, that the test program includes the statements you used to open the database, create the table, and enter the data you are trying to retrieve.

Then you can raise the new issue.

Community forum

If you have any questions about the plugin please post them to the new discussion forum at Ost.io / @litehelpers / Cordova-sqlite-storage.

Professional support

Professional support is available, please contact info@litehelpers.net.

Unit tests

Unit testing is done in spec.

running tests from shell

To run the tests from *nix shell, simply do either:

./bin/test.sh ios

or for Android:

./bin/test.sh android

To run then from a windows powershell do either

.\bin\test.ps1 android

or for Windows (8.1):

.\bin\test.ps1 windows

or for Windows Phone (7/8):

.\bin\test.ps1 wp8

Adapters

Lawnchair Adapter

Common adapter

Please look at the Lawnchair-adapter tree that contains a common adapter, which should also work with the Android version, along with a test-www directory.

Included files

Include the following Javascript files in your HTML:

cordova.js (don't forget!)
lawnchair.js (you provide)
SQLitePlugin.js (in case of Cordova pre-3.0)
Lawnchair-sqlitePlugin.js (must come after SQLitePlugin.js in case of Cordova pre-3.0)

Sample

The name option determines the sqlite database filename, with no extension automatically added. Optionally, you can change the db filename using the db option.

In this example, you would be using/creating a database with filename kvstore:

kvstore = new Lawnchair({name: "kvstore"}, function() {
  // do stuff
);

Using the db option you can specify the filename with the desired extension and be able to create multiple stores in the same database file. (There will be one table per store.)

recipes = new Lawnchair({db: "cookbook", name: "recipes", ...}, myCallback());
ingredients = new Lawnchair({db: "cookbook", name: "ingredients", ...}, myCallback());

KNOWN ISSUE: the new db options are not supported by the Lawnchair adapter. The workaround is to first open the database file using sqlitePlugin.openDatabase().

PouchDB

The adapter is now part of PouchDB thanks to @nolanlawson, see PouchDB FAQ.

Contributing

Community

Testimonials of apps that are using this plugin would be especially helpful.
Reporting issues at litehelpers / Cordova-sqlite-storage / issues can help improve the quality of this plugin.

WARNING: Please do NOT propose changes from your master branch. In general, contributions are rebased using git rebase or git cherry-pick and not merged.

Code

Patches with bug fixes are helpful, especially when submitted with test code.
Other enhancements welcome for consideration, when submitted with test code and are working for all supported platforms. Increase of complexity should be avoided.
All contributions may be reused by @brodybits (Chris Brody) under another license in the future. Efforts will be taken to give credit for major contributions but it will not be guaranteed.
Project restructuring, i.e. moving files and/or directories around, should be avoided if possible.
If you see a need for restructuring, it is better to first discuss it in the forum at Ost.io / @litehelpers / Cordova-sqlite-storage (or in a new issue) where alternatives can be discussed before reaching a conclusion. If you want to propose a change to the project structure:
- Remember to make (and use) a special branch within your fork from which you can send the proposed restructuring;
- Always use git mv to move files & directories;
- Never mix a move/rename operation with any other changes in the same commit.
