Proposed error handling

budgetsHandler.js

const { generic_error_handler } = require('./lib/generice_error_handler');
const { BudgetsService } = require('./lib/generice_error_handler');

module.exports = {
    uploadBudget: async (request, h) => {
        try {
            const response = await BudgetsService.get({ budgetId });
        } 
        cacth(e) {
            if(e instanceof BudgetServiceForbidden) { throw Boom.forbidden(e.get.FORBIDDEN); }
            if(e instanceof ApiBaseError) { generic_error_handler(e); }
            // reraise error, so that it can be handle generically in plugin
            throw e;
        }
    }
}
  

generic_error_handler.js

const { ApiUnauthorized, ApiForbidden, ApiBaseError } = require('./lib/errors');

// This can be abtracted in to a generic plugins so that we don't have to call it in every method
module.exports = {
    generic_error_handler: (error) => {
        if(error instanceof ApiUnauthorized){ throw Boom.unauthorized(); }
        if(error instanceof ApiForbidden){ throw Boom.forbidden(); }
        if(error instanceof ApiNotFound){ throw Boom.notFound(); }
        throw Boom.badImplementation(err);
    }
}

ReportService.js

const { ApiUnauthorized, ApiForbidden, ApiBaseError } = require('./lib/errors');

class ReportsService {
    static async getOrganizationDetails({ orgId, container }) {
        const response = await fetch();
        
        switch (response.status) {
            case 401: throw new ApiUnauthorized(response);
            case 403: throw new ApiForbidden(response);
            default: throw new ApiBaseError(response);
        }
    }
}
