# Introduction to Open Pioneer Trails

## What is Open Pioneer Trails (OPT) ? 

Open Pioneer Trails, or simply OPT, is an open-source framework for creating client-side, GeoIT applications. The architecture consists of a set of packages, which can be used across different applications, or developed within a single application. The technology stack within the OPT framework is composed of the following: <br>

* Vite is used as the development environment and application bundler.&#x20;
* Vitest runs tests
* React provides the foundation for the UI&#x20;
* Chakra UI is used for components
* Internationalization is supported through FormatJS
* Framework code is in TypeScript. It is recommended, but not required, to use TypeScript for application development as well.&#x20;
* PNPM is the package manager.&#x20;
* Applications are shipped as Web Components.&#x20;
