Overview

The directory structure of a basic TEN framework software package is shown below.

.
├── bin/
├── src/
├── manifest.json
├── manifest-lock.json
├── property.json
└── ten_packages/
    ├── extension/
    │   ├── <extension_foo>/
    │   └── <extension_bar>/
    ├── extension_group/
    │   └── <extension_group_x>/
    ├── protocol/
    │   └── <protocol_a>/
    └── system/
        ├── <system_package_1>/
        └── <system_package_2>/

Depending on the programming language, there may be additional required files. For example, in a C++ project, since the build system is ten_gn, a BUILD.gn file would be present. In a Go project, there would be files such as go.mod and go.sum. In a Python project, you might find a requirements.txt file.

TEN Framework Software Package Kinds

There are two types of software packages:

• Release package

• Development package

The relationship between these two package types is as follows:

• A release package can be generated from a development package through a build process.

• If we add source-related content to a release package, it becomes a development package.

• If we remove source-related content from a development package, it becomes a release package.

In short, the directory structures of development and release packages are very similar, with the difference being that a development package includes source-related content, whereas a release package does not.

Development package

The primary purpose of a development package is to develop TEN software packages. For instance, if you want to create a new TEN extension, you can modify an existing development package to achieve this. This is because the development package contains all the source-related content, enabling the creation of new TEN software packages from it.

Release package

The primary purpose of a release package is to create and run graphs. Since no build tasks are required, a release package can be used to perform these actions. However, a development package can also be used for these tasks. Essentially, the application scope of a development package is broader than that of a release package.
