How to develop an application

This chapter contains pratical tutorials, leads on our environment tools, boilerplates, and code-level explanations on the SDK.

Whereas the "deliver" section was intended to be focused on mandatory subjects with little further specification, you should find in this one more detailed information (or links to detailed information) and explanations.

What the framework contains

To get your project started quickly, we provide a complete framework made to develop device applications. This framework works on Linux, Mac and Windows. It contains:

• Several boilerplate applications, to be used as a modifiable bases to create your own application:
  • A C Boilerplate (opens in a new tab)
  • A Rust Boilerplate (opens in a new tab) and
  • A Plugin Boilerplate (opens in a new tab)
• A Visual Studio Code extension (ledger-dev-tools) (opens in a new tab) packaging all the tools required to build, test and load an application inside the VSCode IDE
• An OS emulator called Speculos (opens in a new tab)
• A test framework called Ragger (opens in a new tab), using Speculos
• CI workflows (opens in a new tab)
• Docker containers (opens in a new tab) providing up-to-date development environments

More information on these components can be found in the tutorials, development environment and tools sections.
