Last interview job task (Part 1)

My last interview job-task was to create such small app using Typescript (opens new window) (A super-set of JS) in node.js (opens new window)

I decide to use the Typescript Vue Starter (opens new window) and document my own workflow process to do it. Thanks to multiple reliable & open source documentation ( my words can not express my huge humble gratitute and in the near future i would like to help aswell ). Such as:

• Node Best Practices (opens new window)
• TypeScript Node Starter (opens new window)
• Typescript Node.js from basarat (opens new window)
• Open Weather (opens new window)

The app is simple (as every app should be, following the KISS (opens new window) principle ).

Given an array of ( location-name , postal-code ) show current time & weather

1. Init project

Create a new repo, TimeForecast-OBS (opens new window) in Github.

Set Git ( Global information tracker, a Distributed Version System Control )

git init

skip this part if you configurate you git

git config --global user.email "your_email@example.com"

optional: define alias to save some keystrokes 👍

git config --global alias.co checkout
git config --global alias.br branch
git config --global alias.ci commit
git config --global alias.st status

add remote repo URL

git remote add origin git@github.com:reilue/TimeForecast-OBS.git

Set yarn

yarn init

Later add Typescript and @types/node.

yarn add typescript --dev
yarn add @types/node --dev
npx tsc --init --rootDir src --outDir dist --esModuleInterop --resolveJsonModule --lib es6,dom --module commonjs
echo "/node_modules" > .gitignore
mkdir ./dist
mkdir -p ./src/components

Ok @types/node it's just a contract or node API interface to expose and consume it easily.

npx is a command to run binary file downloaded, it's super helpful to create in this case tsconfig.json.

add a .gitignore file with "/node_modules" to tell git don't track any in file in it.

Optional: Live compile & run

yarn add ts-node --dev
yarn add nodemon --dev

ts-node is used to live compile & run in node nodemon will invoke ts-node whenever a file is changed

and add this snippet to script in the package.json.

  "scripts": {
    "start": "yarn run build:live",
    "build": "tsc -p .",
    "build:live": "nodemon --watch 'src/**/*.ts' --exec 'ts-node' src/index.ts"
  }

great one last step create two file

./src/components/forecast.ts

export function forecast {
  console.log("module Forecast");
}

./src/index.ts

import { forecast } from "./components/forecast/forecast"
console.log(forecast())

in your terminal type yarn start and Voilá. You'll see the "module Forecast" message. 😎

If you follow me, damn dude, you're awesome cause i know it's freaking tedious, bunch of concept to learn, but what i can tell you is, dedicate your time fully focus to:

• learn once,
• automatize,
• update and
• adapt your workflow

Repeat

In the next post i'll create this small app.
