Intermezzo – NestJS + Jest vs Angular + Jasmine

Bingo

Bingo is a small project, written in TypeScript , and developed with Alexandru Badita in launch break (one hour - more or less). You can find sources at https://github.com/alexandru360/PresentationBingoCards/ . Those are my blog posts for Bingo : ( scroll below for the post)

We decided to add an Angular project.  As a immediate consequence , the compile ( tsc ) of the API ( bingo-cards-api) it failes with the first error being:

../node_modules/@types/jasmine/ts3.1/index.d.ts:16:1 – error TS6200: Definitions of the following identifiers conflict with those in another file: beforeAll, beforeEach, afterAll, afterEach, describe, fdescribe, xdescribe, it, fit, xit, expect, DEFAULT_TIMEOUT_INTERVAL, CustomMatcherFactory, CustomEqualityTester

 

Obviously, we have a conflict… And the conflict is done by Angular( that comes with Jasmine by default) and Nest ( that comes with Jest) ( and us, that we have choose Jest)

 

There are 3 solving paths:

  1. Convert all to Jasmine
  2. Convert all to Jest
  3. Eliminate the tests from the Angular , eliminate the tests from Nest and create the own library to test (we have done already this, in bingo-meeting-objects-test)

 

Solution 1 : means re-factor all. Not good.

I have tried the 2 , but , in spite of many tutorials on the internet, some problems have arrived.

So we have the 3 : eliminate all references to Jest and Jasmine, with the exception of bingo-meeting-objects-test

And… it worked!

The easy way to test an application is to make a simple command line version . You can find the code at https://github.com/alexandru360/PresentationBingoCards/blob/master/bingo-meeting-console/index.ts

You can run also with Docker by running https://github.com/alexandru360/PresentationBingoCards/blob/master/dockerize/bingo_cli.bat

What were the steps ?

1. Install the @types/node, ts-node , typescript and others – see

https://github.com/alexandru360/PresentationBingoCards/blob/master/bingo-meeting-console/package.json

2. Create an index.ts with the required CLI ( hint: prompt, figlet, chalk , username , inquirer,console.table are good to have) – read https://dev.to/hugodias/building-your-first-interactive-node-js-cli-1g2c

3. Created an async main() and calling with

(async () => {
  try {
      await main();
        } catch (e) {
      console.log(JSON.stringify(e));
  }
})();

 

4. Modify package.json  to have

“main”: “dist/index.js”,

“types”: “dist/index.d.ts”,

“scripts”: {

“start”: “ts-node index.ts”,

“build”: “tsc”,

“compile”: “tsc”

}

5. Put in the root package

“scripts”: {

“test”: “cd bingo-meeting-objects-test && yarn test”,

“runConsole”: “cd bingo-meeting-console && yarn start”

}

and then run yarn runConsole

I can say that the C# console experience is better 😉

Obtain data from ANAF(local IRS)

In ROmania ANAF is providing a WebAPI that allows access to some of the information that any enterprise should provide. The API is described at https://webservicesp.anaf.ro/PlatitorTvaRest/api/v3/ ,

I have made a C# console and a node,js script.

The differences:

1.it is easiear in node to make an http request.

2. For C# – I think in components. For node – I think in application.

Without further ado, here is the code

using RestSharp;
using System;

namespace InfoAnafWS
{
    class Program
    {
        static void Main(string[] args)
        {
            if(args.Length == 0)
            {
                Console.WriteLine("lipseste CUI ");
                return;
            }
            var client = new RestClient("https://webservicesp.anaf.ro");
            var request = new RestRequest("PlatitorTvaRest/api/v3/ws/tva", Method.POST);
            request.RequestFormat = DataFormat.Json;
            string date = DateTime.Now.AddDays(-5).ToString("yyyy-MM-dd");
            string req = "";
            foreach (var item in args)
            {
                req += string.Format(@"{{'cui': {1}, 'data':'{0}'}}", date, item);
            }
            req = req.Replace("'", "\"");
            req = "[" + req + "]";

            request.AddParameter("application/json", req, ParameterType.RequestBody);
            var data = client.Execute(request);
            Console.WriteLine(data.Content);
        }
    }
}


const start = async () => {
	
let request = require('request');

const d = require('delay');
await d(1000);
var fs = require('fs');
var array = fs.readFileSync('CUI.txt').toString().split("\r\n");
var start=0;

while(start<array.length){
	var nr = Math.floor(Math.random() * Math.floor(495))+1;
	var jsonData=[];
	console.log('start at ' + start+  ' for nr ' + nr);
	var i=0;
	while(i<nr && i+start<array.length){
		jsonData.push({"cui": array[i+start], "data":"2018-03-26"});
		i++;		
	}
	
	var finish=false;
	console.log('array :'+ jsonData[0].cui + '-'  + jsonData[nr-1].cui);
	request.post(
    'https://webservicesp.anaf.ro/PlatitorTvaRest/api/v3/ws/tva',
    { json: jsonData },
    function (error, response, body) {
		finish=true;
        if (!error && response.statusCode == 200) {
            console.log(body);
			fs.writeFile(`text${start}_${nr}.json`, JSON.stringify( body ), function (err) {
            if (err) {
                return console.log(err);
            }

            console.log("The file was saved!" + `text${start}_${nr}.json`);
        });

        }
    });
	start = start+nr;
	while(!finish){
		console.log('waiting');
		await d(13000);
	}
	

}
console.log('finish')
return;

}
start();
