integrate-me v1.0.2

Integrate Me

Simple integration checker for your API services and external modules when it is crucial for your app.

Install

npm i integrate-me

Usage

Package provides a simple builder with methods that take integration name and a async callback. If callback throws then an integration would be considered as failed. Otherwise it is OK.

It designed to use at application start by simply awaiting integrateMeChecker.check() to check all services availability before all application logic.

import { IntegrationCheckBuilder } from 'integrate-me';

const config = {
  retry: 4,            // Retry attemts before failing the check
  throwOnError: false, // default true
};

const integrateMeChecker = new IntegrationCheckBuilder(config)
  .addModuleIntegration('DatabaseConnection', async () => {
    await prisma.$connect(); 
  })
  .addModuleIntegration('myOtherModule', async () => {
    if (1 === 1) {
      Promise.resolve();
    }
  });


const res: IntegrationCheckResult = await integrateMeChecker.check();

If { throwOnError: false } integrateMeChecker will not throw an error if some of the integrations were not successful. The IntegrationCheckResult will be returned instead for manual handling.

interface IntegrationError {
  integrationName: string;
  error: string;
  status: IntegrationStatus.ERROR;
  errObj?: Error;
}

interface IntegrationSuccess {
  integrationName: string;
  status: IntegrationStatus.OK;
}

type IntegrationCheckResult = IntegrationSuccess | IntegrationError;
