TypeScript

TypeScript is an open-source language which builds on JavaScript

Overview

TypeScript is an open-source language which builds on JavaScript by adding static type definitions. Types provide a way to describe the shape of an object, provide better documentation, and allow TypeScript to validate your code.

TypeScript and Angular

Angular applications must be built with TypeScript. As PlaceOS frontend applications are mainly written in Angular, they need TypeScript.

Versioning

TypeScript version depends on your Angular version.

PlaceOS Frontends uses Angular 12 and TypeScript 4.2.4.

TypeScript References and Tooling

The TypeScript Handbook provides detailed documentation specifically related to TypeScript.

PlaceOS uses NX tools to assist with testing and building JavaScript Applications.

NX adds Jest for Unit Testing and Cypress for Integration and End-to-End Testing.

The Angular CLI lets you develop, scaffold and maintain Angular applications. It's used with PlaceOS frontend applications.

Automated Browser Testing

Automated browser testing can check application test cases. Any Selenium based automated test suite would be suitable for this purpose. One possible tool is Katalon Studio.
