Decorators in commands

[lukfor85]

Hi all,

I want to use decorated "run" method in command. My command is defined like so:

import { BaseCommand } from '@adonisjs/core/build/standalone';
import ConversionService from 'App/Services/ConversionService';
import { loggedCommand } from 'Commands/index';

export default class ConvertPaymentsAmount extends BaseCommand {
    public static commandName = 'convert:payments_amount';
    public static description = 'not important';

    public static settings = {
        loadApp: true,
    };

    @loggedCommand()
    public async run(): Promise<{ paymentsConverted: number } | undefined> {
        return ConversionService.convertMissingPaymentsAmount(20, 100);
    }
}

The decorator is a pretty standard one (used for logging command output and performance to database):

export const loggedCommand = (): MethodDecorator => {
    return function (target: any, _propertyKey: string, descriptor: PropertyDescriptor) {
        const originalMethod = descriptor.value;
        descriptor.value = async function (...args: Array<any>) {
            // DB logging code
        };

        return descriptor;
    };
};

All goes well until I want to run
node ace generate:manifest

I am getting

TypeError: (0 , index_1.loggedCommand) is not a function

and the import is undefined when I am trying to log it.

What might be the cause and how is the workaround? Am I doing anything wrong?

Hey @lukfor85! 👋🏻

Since you are using a custom path, ensure you have registered it inside the .adonisrc.json file and the tsconfig.json file.

Also, to ensure this is not an issue about loading, you can try to load your decorator with a relative path.

thank you, relative import helped me instantly. Shame on me I didn't realize such an obvious thing.
