• option 1: start app: npm run start
• option 2: create executable: npm run dist (creates new folder Serial Port Monitor-...)

Screenshots

How it works

Node.js

• JavaScript runtime
• https://nodejs.org/en/
• command: npm - package manager
• file: package.js - description of the app and its dependencies

TypeScript

• JavaScript on steroids (transpiles into JavaScript - makes life much more easier)
• TypeScript in 5 minutes
• file: tsconfig.json - configuration of the TypeScript compiler
• file: tslint.json - additional code analysis and automatic formatting
• command: tsc - transpiles code into JavaScript (folder /dist)

Electron

• creates cross-platform desktop apps with JavaScript, HTML, and CSS
• https://www.electronjs.org/
• command: electron . - finds the main JavaScript file in package.json and starts the application
• command: npm run start - creates JavaScript files and immediately starts the application
• command: npm run dist - builds and creates executable application into the folder /Serial Port Monitor-...

Main process

/ts/main/index.js

• creates an application window;
• links html file into window (file: /web/index.html)
• manages communication with serial port

Renderer process

/ts/renderer/index.js

• linked through the index.html file.
• creates user interface
