Project structure

The project is divided into two parts - data that are used when compiling the project and data that aren't.

All data that are used during compilation are stored inside the src/ folder.

src/ folder

At the root of the src/ folder are all files or folders that are shared.

  • src/index.js - root of the application
  • src/views/ - contains all React components and views
  • src/store/ - todo
  • src/actions/ - todo
  • src/reducers/ - todo
  • todo other folders/files?


Component is what you'd intuitively think it is. It's a regular React component (doesn't matter whether statefull or stateless).

Global components

All global components are stored in src/views/components/ folder. Global components are such components that are shared across multiple different components or views.

  • For example there's a Button component that is used in both ConnectDevice and AccountSend. ConnectDevice and AccountSend are both placed accross different views so the Button component they're both using must be stored in the global components folder.

Naming & structure convention

Each component has it's own folder. Name of the folder is same as is the name of the component (camel case and first letter is capitalized, e.g.: MyComponent).

If you want to create multiple components of the same type you should put them into a common folder with a lowercase name like this views/components/type/MyComponent.

  • For example there are different types of modals like confirm or device. Because the confirm and device modals are subtypes of modal the folder structure looks like this
    Where Address, SignTx and Duplicate are the actual modal components.

Inside each component's folder is index.js file containing the actual component's code with following export at the end of the file export default ComponentName;

There's only one render function per component's index file. If you need more renders you should probably create new component.

Each component may contain other components in its own components/ folder. Component's components may contain another components etc.


The difference between view and component is rather semantical then technical.

From the React's standpoint a view is just another component. So when is component a regular component and when is it a view? View components basically copy router structure and are composed either from view's own components or global components.

Naming & structure convention

Both naming and structure conventions are similar to components conventions. Each view has its own folder in views/ folder. Name of this folder is same as is the view's name (camel case and first letter is capitalized, e.g.: MyView). Inside the view's folder is always an index.js file containing view's code itself.

View may contain own components inside view's folder - in the components/ folder. One of the differences between a component and a view is that view can have another views. Of course those views may have their own components and views, etc.

  • For example there's a Landing component that is displayed if no device is detected. This view contains its own components in a Landing/components/ folder. These components are then used exclusively in Landing/index.js and together compose different versions of the Landing view.


If you are implementing a new feature from 'trezor-connect' which is not deployed on npm yet follow these steps:

  1. Build trezor-connect npm module locally:
  • go to trezor-connect project
  • call yarn build:npm
  • cd npm
  1. Call yarn link to register this module
  2. go to trezor-wallet project
  3. Call yarn link trezor-connect to link registered module with trezor-wallet

Additionally you can publish trezor-connect to dev server (

  1. go to trezor-connect project
  2. call make build-test
