A base application for showing device location history information in table and Google Map layouts.
Potential users may be fleet managers who would subscribe to the locating service provided by the application. Pricing can be determined by built-in administrator controllable service constraints. A detailed description of the user interface is available in the Screenshots.pdf file.
The base application is serverless in that it uses the Google Firebase/Firestore cloud database for access to location data as well as user and account information. Location data may be provided by any device capable of accessing Firestore. A sample Android application for this purpose is provided by https://github.com/lvhellgren/LayTrax.
Tracker is a single page Angular application written in TypeScript taking advantage of Angular features such as routing, reactive processing, templating, Material Design, etc.
Tracker employs Angular Flex-Layout to automatically format UI layouts to fit various screen sizes.
Tracker is designed for modular development. The Core module provides sign-in capability and basic features for use by other modules. The Setup module manages users and accounts as well as the relationships between these entities. Application-specific functionality may be implemented by creating new modules (or by extending existing placeholder modules).
User authentication is provided through the Firebase Java Web Token implementation. Users can sign in using email and password authentication and also through Auth0 identity providers, such as Google.
Users and accounts have a many-to-many relationship, so that a given user may have access to one or more accounts and an account may have one or more users.
User permissions are governed through rules defined in the Firestore database, so that a given user may, for example, be assigned create, update, or read roles for accessing data collections in the database. Users having access to multiple accounts may be given different permissions depending on the account.
Only users in the special Principal account and with create permission can create new accounts. These users will also create the initial user for a new account. An account user with create permission can then create additional users for that account but for that account only.
A user ID created from Tracker must be a valid email address available to the intended user. Initially, a randomly generated, unknown password is created. The user signing in for the first time will then need to use the Create or Reset Password option to create a known password.
