# CLI

The Wails CLI has a number of commands that are used for managing your projects. All commands are run in the following way:

`wails <command> <flags>`

## init

`wails init` is used for generating projects.

|  Flag                |  Description                           |  Default                   |
| :------------------- | :------------------------------------- | :------------------------- |
|  -n "project name"   | Name of the project. **Mandatory**.    |                            |
|  -d "project dir"    | Project directory to create            | Name of the project        |
|  -g                  | Initialise git repository              |                            |
|  -l                  | List available project templates       |                            |
|  -q                  | Suppress output to console             |                            |
|  -t "template name"  | The project template to use. This can be the name of a default template or a URL to a remote template hosted on github.            | vanilla                    |
|  -ide             | Generate IDE project files          |                            |
|  -f                  | Force build application                | false                      |

Example:
  `wails init -n test -d mytestproject -g -ide vscode -q`

This will generate a a project called "test" in the "mytestproject" directory, initialise git,
generate vscode project files and do so silently.

More information on using IDEs with Wails can be found [here](/docs/guides/ides).

### Remote Templates

Remote templates (hosted on GitHub) are supported and can be installed by using the template's project URL.

Example:
 `wails init -n test -t https://github.com/leaanthony/testtemplate`

A list of community maintained templates can be found [here](/docs/community/templates)

:::warning Attention

  **The Wails project does not maintain, is not responsible nor liable for 3rd party templates!**

  If you are unsure about a template, inspect `package.json` and `wails.json` for what scripts are run and what packages are installed.

## build

`wails build` is used for compiling your project to a production-ready binary.

|  Flag                |  Description                            |  Default                   |

If you prefer to build using standard Go tooling, please consult the [Manual Builds](/docs/guides/manual-builds)
guide.

Example:

`wails build -clean -o myproject.exe`

## doctor

`wails doctor` will run diagnostics to ensure that your system is ready for development.

Example:
```
Wails CLI v2.0.0-beta

## dev

`wails dev` is used to run your application in a "live development" mode. This means:

   - The application is compiled and run automatically
   - A watcher is started and will trigger a rebuild of your dev app if it detects changes to your go files
   - A webserver is started on `http://localhost:34115` which serves your application (not just frontend) over http. This allows you to use your favourite browser development extensions
   - All application assets are loaded from disk. If they are changed, the application will automatically reload (not rebuild). All connected browsers will also reload
   - A JS module is generated that provides the following:
     - Javascript wrappers of your Go methods with autogenerated JSDoc, providing code hinting
     - TypeScript versions of your Go structs, that can be constructed and passed to your go methods
   - A second JS module is generated that provides a wrapper + TS declaration for the runtime

|  Flag                |  Description                            |  Default                   |
| :------------------- | :-------------------------------------- | :------------------------- |
|  -assetdir "./path/to/assets" | The path to your compiled assets  | Value in `wails.json` |
|  -browser | Opens a browser to `http://localhost:34115` on startup | |
|  -compiler "compiler"| Use a different go compiler to build, eg go1.15beta1 | go            |
|  -e                  | Extensions to trigger rebuilds (comma separated)  | go |
|  -ldflags "flags"    | Additional ldflags to pass to the compiler |                         |
|  -tags "extra tags"  | Build tags to pass to compiler (quoted and space separated) |        |
|  -loglevel "loglevel"| Loglevel to use - Trace, Debug, Info, Warning, Error | Debug         |
|  -noreload           | Disable automatic reload when assets change | |
|  -v                  | Verbosity level (0 - silent, 1 - standard, 2 - verbose)  | 1 |
|  -wailsjsdir         | The directory to generate the generated Wails JS modules | Value in `wails.json` |
|  -debounce         | The time to wait for reload after an asset change is detected  | 100 (milliseconds) |
|  -devserverurl "url"         | Use 3rd party dev server url, EG Vite  | "http://localhost:34115" |

If the `assetdir`, `wailsjsdir`, `debounce` or `devserverurl` flags are provided on the command line, they are saved in
`wails.json`, and become the defaults for subsequent invocations.

Example:

`wails dev -assetdir ./frontend/dist -wailsjsdir ./frontend/src -browser`

This command will do the following:

  - Build the application and run it (more details [here](/docs/guides/manual-builds)
  - Generate the Wails JS modules in `./frontend/src`
  - Watch for updates to files in `./frontend/dist` and reload on any change
  - Open a browser and connect to the application

There is more information on using this feature with existing framework scripts [here](/docs/guides/application-development#live-reloading).

## generate

### template

Wails uses templates for project generation. The `wails generate template` command helps scaffold a template so that
it may be used for generating projects.

|  Flag                |  Description                                 |
| :------------------- | :------------------------------------------- |
|  -name               | The template name (Mandatory)                |
|  -frontend "path"    | Path to frontend project to use in template  |

For more details on creating templates, consult the [Templates guide](/docs/guides/templates).

## update

`wails update` will update the version of the Wails CLI.

|  Flag                |  Description                            |
| :------------------- | :-------------------------------------- |
|  -pre                | Update to latest pre-release version    |
|  -version "version"  | Install a specific version of the CLI   |


## version

`wails version` will simply output the current CLI version.
