# App Package

## Introduction

App package is a zip package, including app configuration files, code files for implementing app functions and other static resources. The root directory of app package must contain a configuration file called `manifest.json`.

Apps are developed using `HTML+Javascript+CSS` technologies. You can use popular frameworks to develop your apps, such as `React + Typescript`. You can host these resources in Comm100 System or other servers.

## Structure

The root directory of app package must contain `manifest.json` file. When uploading a package, the system will check this file in the root directory. There are no strict requirements for the organization of other resources, but the general app package structure is as follows:

- `css` folder: All style and font files are here.
- `images` folder: All the picture resources are put here.
- `js` folder: All the script files are here.
- `index.html`: The entry page of the app. If your app is configured with multiple widgets, there may be multiple entry pages in one app package.
- `manifest.json`: The config file for the app.

The `manifest.json` is the configuration file of the app. Click [here](/docs/app-manifest) for more information.
