![]() ![]() We initially worked around this issue by copying a pre-populated sqlite3 database to a special directory where it would be picked up by WebKit (e.g. Pre-populating the database via javascript adds to initial app load time.Size of database is limited to 5MB (the user can be prompted to allow more, but we didn't want such prompts in our app).We started off using a plain old Web SQL Database in our PhoneGap app, but ran into the following limitations: ![]() (key, value).We ended up using the PhoneGap SQLite plugin, here's why: Replace below code: import from 'app-home', In the file, import plugin then adds in Imports array in NgModule. $ npm install -save Import declare plugin in Application's module file To enable SQLite storage in the Ionic application, we'll install Cordova plugin and Native wrapper module by running below commands $ ionic cordova plugin add cordova-sqlite-storage ![]() # Install Cordova and Ionic Native Plugin Move to the application directory $ cd ionic-sqlite-tutorial Now we'll create a new Ionic application using Angular framework by adding -type=angular option with a blank template $ ionic start ionic-sqlite-tutorial blank -type=angular Run the following command to install or update the package to build Ionic 5 application using Angular version 8 $ npm install -g Create a new Ionic application We are going to create Ionic Angular application in latest version 6.6.0. Let’s start the implementation of SQLite Plugin in Ionic Application # Update Ionic CLI But Ionic Storage is a substituting to LocalStorage to save data in Key-Value pairs which we discussed here. SQLite Database acts like a real database where SQL queries can be executed to do CRUD operations. Note: Ionic SQLite Database and Ionic Storage using SQLite plugin work diffently. Ionic 4 | Storage Tutorial in Ionic using Native Storage PluginĬomplete SQLite CRUD Tutorial for Ionic 4 Angular Applications On Progressive Web Apps platform IndevedDB, WebSQL or localStorage is chosen in a defined order. LocalStorage engines are managed by the plugin itself according to OS on which application is installed or running like in Native app context Storage will be done using SQLite, which is one of the most stable and most preferred file-based storage databases. But this locally stored data will remain until the application is Uninstalled or device is formatted. Using Ionic’s Native storage plugin we can storage key-value pairs which may have any type of data from a simple string or integers to JSON objects. The selection of storage type is managed by the Ionic framework itself.Īpplication developers sometimes need to save a bunch of information on the user side to control some features and provide some offline functionalities to application users, in that case, local storage proves very handy. Ionic Storage can be used in Web as well as in native devices but web uses LocalStorage and Native device use SQlite based storage system. Hybrid Applications built using Ionic Framework can easily access and use Native storage systems like SQLite. In a portable device, storage helps a developer to store local data like user settings, offline records, profile preferences etc. Storage capacity mainly depends on device memory thus provides a good space to do common tasks on a local device. It is a relational database management system which is available in a device itself to store local data on a device. ![]() The SQLite type of storage is used by most of the Native devices like android. In Ionic’s Angular, we use Native wrapper to access SQLite storage in a native device. In this post, we’ll discuss how to use SQLite storage in an Ionic application using Cordova’s cordova-sqlite-storage plugin. ![]()
