We will be using `SQLite` for this purpose with `WebSql` fallback when in developing. SQLite with WebSQL fallback (our choice and the defacto for many production ready hybrid apps). Cache Storage (better used with Service Workers, however that's an advanced use case and most likely not very useful in case of tabular data).ģ. Local Storage (not good for critical or persistent data, can be erased by OS when running out of memory).Ģ. There are a few options when it comes to choosing a database library:ġ.

Next in the line is the database library selection. However, this also means that if we want something to be available through the app, we need to use a provider (or a service, this days both are almost the same). Thus, using scopes, we can find and fix bugs more easily. Angular 2 scopes isolate each component, which is great since errors in one component will not affect the other. **Note 2:** Also note this command is made to work in unix-based terminals, so if you're in a different OS like `Windows`, you'll need to edit that command accordingly (or install a unix terminal).

**Note 1:** In case you're not very skilled with the terminal, using `&` between commands ensure all of them are run in serial way, and if one fails the next ones doesn't execute. At the end your browser should show something similar to this: The whole process could take between one and five minutes, depending on your ethernet bandwidth and your computer's CPU, RAM, and drive speed. You'll probably see a lot of output in the console from Ionic about downloading and installing modules and building your app before showing it in the browser. That will start an Ionic 2 `typescript` app using the side menu starter, and after it finishes it will open the folder and start the app, your browser will open and show you your new app. Ionic start ionicDBManagerGuide sidemenu -v2 -ts & cd ionicDBManagerGuide & ionic serve

Īfter the Ionic CLI (Command Line Interface) is installed, we need to create a new app we will use the side menu starter repo. Next let's install Ionic 2 with npm, open a console and type the following commands which will install both `cordova` and which is the current version of ionic 2 since it's still in beta as of. Installation is relatively straightforward and covered thoroughly in other guides. The first thing to do is creating a new Ionic 2 app, if you are adding this feature to an existing app jump to the next section.įirst we need to have `Node` and `NPM` (Node Package Manager) installed. Using raw queries for getting insertions IDs. This guide will teach you the following parts of database management in Ionic 2:ģ. This may not be a must-have in all applications, but if you choose the path of `offline first` for mobile app (usually an easy choice since a mobile device often gets disrupted signal when used without wi-fi), you'll have to rely on a local database to store data. This guide will cover building an essential part of the app: `databases`. However, hybrid app structure standards are still very limited in Ionic 2. The hybrid mobile app market has been expanding a lot since the release of `Ionic 2`, built with `Angular 2`. Since Ionic 2.0-RC.0 the SqlStorage package that this tutorial rely on has been removed, and the WebSql fallback support has been dropped, you may be able to use versioning to only SqLite in mobile but web version has been sent to the trash, i'd suggest to stop thinking in Sql like databases and start learning NoSql since it seems browsers are moving into it (specially since WebSql specs are deprecated and the only browser that still works WebSql is Chrome).
