🛠️ Installation

In addition to the graphical start-up method based on VeighNa Station, you can also create run.py in any directory and write the following sample code:

// Bad
validateAndSubmitForm() {
    // validate...
    this.setState({isLoading: true});
    signIn()
        .then((response) => {
            if (result.jsonCode === 200) {
                return;
            }

            this.setState({error: response.message});
        })
        .finally(() => {
            this.setState({isLoading: false});
        });
}

// Good
validateAndSubmitForm() {
    // validate...
    signIn();
}
