It has a number of commands:
This will output the cli help message with all the available commands and flags.
The setup command does a number of things - it asks you for your name and email so that it can fill in project templates with your details. It also checks to see if your environment has the dependencies it needs and if not, try to suggest ways on how to install those dependencies.
Setup is also the default command so it can be invoked by simply running
The init command builds out a new project based on a template of your choice. We curently support a number of frameworks including Vue, Vuetify, React, Angular and Svelte. The project will be built automatically after initialisation.
This template consists of a frontend composed of Vue components, bundled together using Webpack. It makes a simple call to the backend.
This template consists of a frontend composed of Vuetify components, bundled together using Webpack. It makes a simple call to the backend.
This template consists of a frontend composed of React components, bundled together using Webpack. It makes a simple call to the backend.
This template consists of a frontend composed of Svelte components, bundled together using Rollup. It makes a simple call to the backend.
This template is a basic angular app using webpack.
When you run
wails serve, it will compile up the backend and run it in headless mode. This allows you to develop the frontend using your standard tooling. When you run your app, it will connect to the backend at startup and make all your backend functions available to you.
We will cover this more in the tutorial.
The build command is the Wails equivalent of
go build, however it does a number of things:
Here is a list of all available flags:
|-f||Force rebuild of frontend dependencies|
|-d||Build application in Debug mode|
|-p||Package application after a successful build|
|-x||Cross-compile to different platform|
|-verbose||Increased output from the build process|
-p flag is currently supports OSX and Windows. On OSX, it bundles your binary into a .app file with the default icon. On Windows, it will generate the application resource files and compile it all into a ‘.exe’. When the
-p flag is used, the packaging files are left available for editing. Any changes will be picked up by the next build (eg icon).
Wails support cross-compiling to the other supported platforms. The target platform is passed using the
-x flag. Example:
wails build -x windows/amd64
This also supports the
-p flag for packaging.
The builds are placed in a
build directory, in your project root directory.
NOTE: Docker is required for this feature
This command does a check to see if the current version is the latest. If not, it will download and install the latest version. It is possible to also use it to install ‘prerelease’ versions by using the
-pre flag. If a specific version is required, then it supports a
wails update -pre will update the latest prerelease version
This command speeds up the process for submitting an issue to the Wails project. When you run the command, you will be asked to answer a couple of questions:
Wails then determines some environmental details such as it’s own version, opens a browser and fills in the default issue template.
Please note: you can edit the template as you feel fit before submitting.
You now have a good basis for your template. Running
wails init will now give you your template as an option to install. When the project is generated using the template, it will create directories, copy non-template files then copy template files. Template files end in .template and will be treated as standard Go templates in which embedded codes are substituted with values in the Project Options.
