Notes

To see the available commands for rnhc you can run:

rnhc --help

To see the available positionals and options for a specific command like create you can run:

rnhc create --help

In order to rnhc to work, you must be at the root of your React Native project. It will check and if somehow you are not at the root of the project, rnhc will prompt:

You don't seem to be at the root of a react native project

In create command, rnhc will create files with the project's used language, so if the project is written with TypeScript, it will write files with TypeScript, the same apply for JavaScript.
If you are in a JavaScript project and somehow you want to create your component or screen in TypeScript, you can use the --typescript or --ts option:

rnhc create -s test-screen --ts

It doesn't matter what case you name your component or screen, rnhc will always create a component or screen with the same name, but with the first letter in uppercase, and the folder will be in kebab case. So if you name your component with test-comp, it will create a component or screen with the name TestComp in the index.jsx file under the ./src/components/test-comp/ folder. Check the example below:

rnhc create -c test-comp

rnhc create -c testComp

rnhc create -c TestComp

The above commands produce the same outcome:

JavaScript
TypeScript

src/
└── components
    └── test-comp
        ├── __tests__
        │   └── index.spec.jsx
        ├── index.jsx
        └── styles.js

src/
└── components
    └── test-comp
        ├── __tests__
        │   └── index.spec.tsx
        ├── index.tsx
        └── styles.ts

You can always overwrite your implementation using the --overwrite or -o option, for example:

rnhc create -c test-component -o

rnhc create -s TestScreen -o

rnhc create -r -o

rnhc create --reducer testReducer -o

rnhc create --action testReducer test-action -o

This is helpful when you want to update your navigation files, for example you already have a navigation file in src/screens/ folder and you want to update it with the new screens you created:

rnhc create -n stack --overwrite

When creating reducers you should have already a redux implmentation created with rnhc create -r so it can work.
When creating actions, you should have already a redux implementation created with rnhc create -r as well as an existed reducer with rnhc create --reducer <reducer-name> so it can create actions for that specific reducer.
Creating and deleting reducers and actions will not just delete files, but also update other files that depends on them under the src/redux/ folder (Or your specified path for the root of redux folder in rnhc.config.json).
You can use the --silent option to avoid the prompts for all commands:

rnhc create -c foo --silent

rnhc will recommend you similar commands if you type a command that doesn't exist. For example, if you type rnhc crete -c, it will prompt you with the following:

rnhc <command> [option]

Commands:
  rnhc create [name]   Create components, screens, navigations and redux
                       implementation
  rnhc delete [name]   Delete components, screens, navigations and redux
                       implementation
  rnhc combine [name]  Combine components or screens in a folder

Options:
  --version  Show version number                                       [boolean]
  --silent   Do not show log messages                                  [boolean]
  --help     Show help                                                 [boolean]

Did you mean create?

When creating, deleting or combining components in atom design pattern, if you provide more than one type (e.g rnhc create -c test --atom --molecule), rnhc will prompt you to choose one of them.
