Requirements

• nvm (to download the correct version of Node)
• csv asset to read and test stuff. You can use this one Kagle

Instalation

• git clone https://github.com/henriquesss/web-workers-at-browser
• nvm use
• npm run start

Architecture

• src/controller.js= Intermediador/validador de recursos
• src/index.js = Centraliza tudo para ser importado pelo index.html
• src/service.js = Regras de negócio
• src/view.js = Operacoes de frontend
• src/worker.js = Operacoes nas threads do navegador

Apprenticeship

• cat database.csv | wc-l (count the number of lines in a file)
• Work threads is paralels threads running with main
• Too much console.log can downgrade de software performance

Todo

• Improve UI of the project
• Create a new layer with validations (middleware?)
• Discover and use a good practice at src/service.jsinstead of lines.shift()
• Use lib csvtojson instead of function at src/service.js
• Fix the line numbers
