¶ Write a code
The easiest way to start is to procure an application that you can create using Extreme CLI:
$ guitar-shop app init
After generating the workpiece, you will see something like this catalog tree:
guitar-shop/
functions/
setup/
src/
setup.ts
package.json
ui/
src/
app.tsx
main.tsx
index.html
package.json
Open the file guitar-shop/ui/src/app.tsx in the editor and add the following code to the App:
function App() {
return <h1> Hello Extremum! </h1>;
}
Assemble the front-end:
$ cd guitar-shop/ui
$ npm install
$ npm run build
Check that everything works correctly by executing the following command from the directory guitar-shop/ui:
$ npm start
If everything is fine, a new browser tab will open with a login page to the application.
Enter the user name (for example, who you are logged into your CLI account) and password, click "Sign In." A page with the following content should open:
Congratulations, your first app is ready!
